5 This is a filetype plugin to work with SQL files.
6
7 The Structured Query Language (SQL) is a standard which specifies statements
8 that allow a user to interact with a relational database. Vim includes
9 features for navigation, indentation and syntax highlighting.

32 ==============================================================================
33 1. Navigation *sql-navigation*
34
35 The SQL ftplugin provides a number of options to assist with file
36 navigation.
37
38
39 1.1 Matchit *sql-matchit*
40 -----------
41 The matchit plugin (http://www.vim.org/scripts/script.php?script_id=39)
42 provides many additional features and can be customized for different
43 languages. The matchit plugin is configured by defining a local
44 buffer variable, b:match_words. Pressing the % key while on various
45 keywords will move the cursor to its match. For example, if the cursor
46 is on an "if", pressing % will cycle between the "else", "elseif" and
47 "end if" keywords.
48
49 The following keywords are supported: >
50 if
51 elseif | elsif
52 else [if]
53 end if
54
55 [while condition] loop
56 leave
57 break
58 continue
59 exit
60 end loop
61
62 for
63 leave
64 break
65 continue
66 exit
67 end loop
68
69 do
70 statements
71 doend
72
73 case
74 when
75 when
76 default
77 end case
78
79 merge
80 when not matched
81 when matched
82
83 create[ or replace] procedure|function|event
84 returns
85
86
87 1.2 Text Object Motions *sql-object-motions*
88 -----------------------
89 Vim has a number of predefined keys for working with text |object-motions|.
90 This filetype plugin attempts to translate these keys to maps which make sense
91 for the SQL language.
92
93 The following |Normal| mode and |Visual| mode maps exist (when you edit a SQL
94 file): >
95 ]] move forward to the next 'begin'
96 [[ move backwards to the previous 'begin'
97 ][ move forward to the next 'end'
98 [] move backwards to the previous 'end'
99
100
101 1.3 Predefined Object Motions *sql-predefined-objects*
102 -----------------------------
103 Most relational databases support various standard features, tables, indices,
104 triggers and stored procedures. Each vendor also has a variety of proprietary
105 objects. The next set of maps have been created to help move between these
106 objects. Depends on which database vendor you are using, the list of objects
107 must be configurable. The filetype plugin attempts to define many of the
108 standard objects, plus many additional ones. In order to make this as
109 flexible as possible, you can override the list of objects from within your
110 |vimrc| with the following: >
111 let g:ftplugin_sql_objects = 'function,procedure,event,table,trigger' .
112 \ ',schema,service,publication,database,datatype,domain' .
113 \ ',index,subscription,synchronization,view,variable'
114
115 The following |Normal| mode and |Visual| mode maps have been created which use
116 the above list: >
117 ]} move forward to the next 'create <object name>'
118 [{ move backward to the previous 'create <object name>'
119
120 Repeatedly pressing ]} will cycle through each of these create statements: >
121 create table t1 (
122 ...
123 );
124
125 create procedure p1
126 begin
127 ...
128 end;
129
130 create index i1 on t1 (c1);
131
132 The default setting for g:ftplugin_sql_objects is: >
133 let g:ftplugin_sql_objects = 'function,procedure,event,' .
134 \ '\\(existing\\\\|global\\s\\+temporary\\s\\+\\)\\\{,1}' .
135 \ 'table,trigger' .
136 \ ',schema,service,publication,database,datatype,domain' .
137 \ ',index,subscription,synchronization,view,variable'
138
139 The above will also handle these cases: >
140 create table t1 (
141 ...
142 );
143 create existing table t2 (
144 ...
145 );
146 create global temporary table t3 (
147 ...
148 );
149
150 By default, the ftplugin only searches for CREATE statements. You can also
151 override this via your |vimrc| with the following: >
152 let g:ftplugin_sql_statements = 'create,alter'
153
154 The filetype plugin defines three types of comments: >
155 1. --
156 2. //
157 3. /*
158 *
159 */
160
161 The following |Normal| mode and |Visual| mode maps have been created to work
162 with comments: >
163 ]" move forward to the beginning of a comment
164 [" move forward to the end of a comment
165
166
167
168 1.4 Macros *sql-macros*
169 ----------
170 Vim's feature to find macro definitions, |'define'|, is supported using this
171 regular expression: >
172 \c\<\(VARIABLE\|DECLARE\|IN\|OUT\|INOUT\)\>
173
174 This addresses the following code: >
175 CREATE VARIABLE myVar1 INTEGER;
176
177 CREATE PROCEDURE sp_test(
178 IN myVar2 INTEGER,
179 OUT myVar3 CHAR(30),
180 INOUT myVar4 NUMERIC(20,0)
181 )
182 BEGIN
183 DECLARE myVar5 INTEGER;
184
185 SELECT c1, c2, c3
186 INTO myVar2, myVar3, myVar4
187 FROM T1
188 WHERE c4 = myVar1;
189 END;
190
191 Place your cursor on "myVar1" on this line: >
192 WHERE c4 = myVar1;
193 ^
194
195 Press any of the following keys: >
196 [d
197 [D
198 [CTRL-D
199
200
201 ==============================================================================
202 2. SQL Dialects *sql-dialects* *sql-types*
203 *sybase* *TSQL* *Transact-SQL*
204 *sqlanywhere*
205 *oracle* *plsql* *sqlj*
206 *sqlserver*
207 *mysql* *postgres* *psql*
208 *informix*
209
210 All relational databases support SQL. There is a portion of SQL that is
211 portable across vendors (ex. CREATE TABLE, CREATE INDEX), but there is a
212 great deal of vendor specific extensions to SQL. Oracle supports the
213 "CREATE OR REPLACE" syntax, column defaults specified in the CREATE TABLE
214 statement and the procedural language (for stored procedures and triggers).
215
216 The default Vim distribution ships with syntax highlighting based on Oracle's
217 PL/SQL. The default SQL indent script works for Oracle and SQL Anywhere.
218 The default filetype plugin works for all vendors and should remain vendor
219 neutral, but extendable.
220
221 Vim currently has support for a variety of different vendors, currently this
222 is via syntax scripts. Unfortunately, to flip between different syntax rules
223 you must either create:
224 1. New filetypes
225 2. Custom autocmds
226 3. Manual steps / commands
227
228 The majority of people work with only one vendor's database product, it would
229 be nice to specify a default in your |vimrc|.
230
231
232 2.1 SQLSetType *sqlsettype* *SQLSetType*
233 --------------
234 For the people that work with many different databases, it would be nice to be
235 able to flip between the various vendors rules (indent, syntax) on a per
236 buffer basis, at any time. The ftplugin/sql.vim file defines this function: >
237 SQLSetType
238
239 Executing this function without any parameters will set the indent and syntax
240 scripts back to their defaults, see |sql-type-default|. If you have turned
241 off Vi's compatibility mode, |'compatible'|, you can use the <Tab> key to
242 complete the optional parameter.
243
244 After typing the function name and a space, you can use the completion to
245 supply a parameter. The function takes the name of the Vim script you want to
246 source. Using the |cmdline-completion| feature, the SQLSetType function will
247 search the |'runtimepath'| for all Vim scripts with a name containing 'sql'.
248 This takes the guess work out of the spelling of the names. The following are
249 examples: >
250 :SQLSetType
251 :SQLSetType sqloracle
252 :SQLSetType sqlanywhere
253 :SQLSetType sqlinformix
254 :SQLSetType mysql
255
256 The easiest approach is to the use <Tab> character which will first complete
257 the command name (SQLSetType), after a space and another <Tab>, display a list
258 of available Vim script names: >
259 :SQL<Tab><space><Tab>
260
261
262 2.2 SQL Dialect Default *sql-type-default*
263 -----------------------
264 As mentioned earlier, the default syntax rules for Vim is based on Oracle
265 (PL/SQL). You can override this default by placing one of the following in
266 your |vimrc|: >
267 let g:sql_type_default = 'sqlanywhere'
268 let g:sql_type_default = 'sqlinformix'
269 let g:sql_type_default = 'mysql'
270
271 If you added the following to your |vimrc|: >
272 let g:sql_type_default = 'sqlinformix'
273
274 The next time edit a SQL file the following scripts will be automatically
275 loaded by Vim: >
276 ftplugin/sql.vim
277 syntax/sqlinformix.vim
278 indent/sql.vim
279 >
280 Notice indent/sqlinformix.sql was not loaded. There is no indent file
281 for Informix, Vim loads the default files if the specified files does not
282 exist.
283
284
285 ==============================================================================
286 3. Adding new SQL Dialects *sql-adding-dialects*
287
288 If you begin working with a SQL dialect which does not have any customizations
289 available with the default Vim distribution you can check http://www.vim.org
290 to see if any customization currently exist. If not, you can begin by cloning
291 an existing script. Read |filetype-plugins| for more details.
292
293 To help identify these scripts, try to create the files with a "sql" prefix.
294 If you decide you wish to create customizations for the SQLite database, you
295 can create any of the following: >
296 Unix
297 ~/.vim/syntax/sqlite.vim
298 ~/.vim/indent/sqlite.vim
299 Windows
300 $VIM/vimfiles/syntax/sqlite.vim
301 $VIM/vimfiles/indent/sqlite.vim
302
303 No changes are necessary to the SQLSetType function. It will automatically
304 pickup the new SQL files and load them when you issue the SQLSetType command.
305
306
307 ==============================================================================
308 4. OMNI SQL Completion *sql-completion*
309 *omni-sql-completion*
310
311 Vim 7 includes a code completion interface and functions which allows plugin
312 developers to build in code completion for any language. Vim 7 includes
313 code completion for the SQL language.
314
315 There are two modes to the SQL completion plugin, static and dynamic. The
316 static mode populates the popups with the data generated from current syntax
317 highlight rules. The dynamic mode populates the popups with data retrieved
318 directly from a database. This includes, table lists, column lists,
319 procedures names and more.
320
321 4.1 Static Mode *sql-completion-static*
322 ---------------
323 The static popups created contain items defined by the active syntax rules
324 while editing a file with a filetype of SQL. The plugin defines (by default)
325 various maps to help the user refine the list of items to be displayed.
326 The defaults static maps are: >
327 imap <buffer> <C-C>a <C-\><C-O>:call sqlcomplete#Map('syntax')<CR><C-X><C-O>
328 imap <buffer> <C-C>k <C-\><C-O>:call sqlcomplete#Map('sqlKeyword')<CR><C-X><C-O>
329 imap <buffer> <C-C>f <C-\><C-O>:call sqlcomplete#Map('sqlFunction')<CR><C-X><C-O>
330 imap <buffer> <C-C>o <C-\><C-O>:call sqlcomplete#Map('sqlOption')<CR><C-X><C-O>
331 imap <buffer> <C-C>T <C-\><C-O>:call sqlcomplete#Map('sqlType')<CR><C-X><C-O>
332 imap <buffer> <C-C>s <C-\><C-O>:call sqlcomplete#Map('sqlStatement')<CR><C-X><C-O>
333
334 The static maps (which are based on the syntax highlight groups) follow this
335 format: >
336 imap <buffer> <C-C>k <C-\><C-O>:call sqlcomplete#Map('sqlKeyword')<CR><C-X><C-O>
337
338 This command breaks down as: >
339 imap - Create an insert map
340 <buffer> - Only for this buffer
341 <C-C>k - Your choice of key map
342 <C-\><C-O> - Execute one command, return to Insert mode
343 :call sqlcomplete#Map( - Allows the SQL completion plugin to perform some
344 housekeeping functions to allow it to be used in
345 conjunction with other completion plugins.
346 Indicate which item you want the SQL completion
347 plugin to complete.
348 In this case we are asking the plugin to display
349 items from the syntax highlight group
350 'sqlKeyword'.
351 You can view a list of highlight group names to
352 choose from by executing the
353 :syntax list
354 command while editing a SQL file.
355 'sqlKeyword' - Display the items for the sqlKeyword highlight
356 group
357 )<CR> - Execute the :let command
358 <C-X><C-O> - Trigger the standard omni completion key stroke.
359 Passing in 'sqlKeyword' instructs the SQL
360 completion plugin to populate the popup with
361 items from the sqlKeyword highlight group. The
362 plugin will also cache this result until Vim is
363 restarted. The syntax list is retrieved using
364 the syntaxcomplete plugin.
365
366 Using the 'syntax' keyword is a special case. This instructs the
367 syntaxcomplete plugin to retrieve all syntax items. So this will effectively
368 work for any of Vim's SQL syntax files. At the time of writing this includes
369 10 different syntax files for the different dialects of SQL (see section 3
370 above, |sql-dialects|).
371
372 Here are some examples of the entries which are pulled from the syntax files: >
373 All
374 - Contains the contents of all syntax highlight groups
375 Statements
376 - Select, Insert, Update, Delete, Create, Alter, ...
377 Functions
378 - Min, Max, Trim, Round, Date, ...
379 Keywords
380 - Index, Database, Having, Group, With
381 Options
382 - Isolation_level, On_error, Qualify_owners, Fire_triggers, ...
383 Types
384 - Integer, Char, Varchar, Date, DateTime, Timestamp, ...
385
386
387 4.2 Dynamic Mode *sql-completion-dynamic*
388 ----------------
389 Dynamic mode populates the popups with data directly from a database. In
390 order for the dynamic feature to be enabled you must have the dbext.vim
391 plugin installed, (http://vim.sourceforge.net/script.php?script_id=356).
392
393 Dynamic mode is used by several features of the SQL completion plugin.
394 After installing the dbext plugin see the dbext-tutorial for additional
395 configuration and usage. The dbext plugin allows the SQL completion plugin
396 to display a list of tables, procedures, views and columns. >
397 Table List
398 - All tables for all schema owners
399 Procedure List
400 - All stored procedures for all schema owners
401 View List
402 - All stored procedures for all schema owners
403 Column List
404 - For the selected table, the columns that are part of the table
405
406 To enable the popup, while in INSERT mode, use the following key combinations
407 for each group (where <C-C> means hold the CTRL key down while pressing
408 the space bar):
409 Table List - <C-C>t
410 - <C-X><C-O> (the default map assumes tables)
411 Stored Procedure List - <C-C>p
412 View List - <C-C>v
413 Column List - <C-C>c
414
415 Windows platform only - When viewing a popup window displaying the list
416 of tables, you can press <C-Right>, this will
417 replace the table currently highlighted with
418 the column list for that table.
419 - When viewing a popup window displaying the list
420 of columns, you can press <C-Left>, this will
421 replace the column list with the list of tables.
422 - This allows you to quickly drill down into a
423 table to view it's columns and back again.
424
425 The SQL completion plugin caches various lists that are displayed in
426 the popup window. This makes the re-displaying of these lists very
427 fast. If new tables or columns are added to the database it may become
428 necessary to clear the plugins cache. The default map for this is: >
429 imap <buffer> <C-C>R <C-\><C-O>:call sqlcomplete#Map('ResetCache')<CR><C-X><C-O>
430
431
432 4.3 SQL Tutorial *sql-completion-tutorial*
433 ----------------
434
435 This tutorial is designed to take you through the common features of the SQL
436 completion plugin so that: >
437 a) You gain familiarity with the plugin
438 b) You are introduced to some of the more common features
439 c) Show how to customize it to your preferences
440 d) Demonstrate "Best of Use" of the plugin (easiest way to configure).
441
442 First, create a new buffer: >
443 :e tutorial.sql
444
445
446 Static features
447 ---------------
448 To take you through the various lists, simply enter insert mode, hit:
449 <C-C>s (show SQL statements)
450 At this point, you can page down through the list until you find "select".
451 If you are familiar with the item you are looking for, for example you know
452 the statement begins with the letter "s". You can type ahead (without the
453 quotes) "se" then press:
454 <C-Space>t
455 Assuming "select" is highlighted in the popup list press <Enter> to choose
456 the entry. Now type:
457 * fr<C-C>a (show all syntax items)
458 choose "from" from the popup list.
459
460 When writing stored procedures using the "type" list is useful. It contains
461 a list of all the database supported types. This may or may not be true
462 depending on the syntax file you are using. The SQL Anywhere syntax file
463 (sqlanywhere.vim) has support for this: >
464 BEGIN
465 DECLARE customer_id <C-C>T <-- Choose a type from the list
466
467
468 Dynamic features
469 ----------------
470 To take advantage of the dynamic features you must first install the
471 dbext.vim plugin (http://vim.sourceforge.net/script.php?script_id=356). It
472 also comes with a tutorial. From the SQL completion plugin's perspective,
473 the main feature dbext provides is a connection to a database. dbext
474 connection profiles are the most efficient mechanism to define connection
475 information. Once connections have been setup, the SQL completion plugin
476 uses the features of dbext in the background to populate the popups.
477
478 What follows assumes dbext.vim has been correctly configured, a simple test
479 is to run the command, :DBListTable. If a list of tables is shown, you know
480 dbext.vim is working as expected. If not, please consult the dbext.txt
481 documentation.
482
483 Assuming you have followed the dbext-tutorial you can press <C-C>t to
484 display a list of tables. There is a delay while dbext is creating the table
485 list. After the list is displayed press <C-W>. This will remove both the
486 popup window and the table name already chosen when the list became active. >
487
488 4.3.1 Table Completion: *sql-completion-tables*
489
490 Press <C-C>t to display a list of tables from within the database you
491 have connected via the dbext plugin.
492 NOTE: All of the SQL completion popups support typing a prefix before pressing
493 the key map. This will limit the contents of the popup window to just items
494 beginning with those characters. >
495
496 4.3.2 Column Completion: *sql-completion-columns*
497
498 The SQL completion plugin can also display a list of columns for particular
499 tables. The column completion is trigger via <C-C>c.
500
501 NOTE: The following example uses <C-Right> to trigger a column list while
502 the popup window is active. This map is only available on the Windows
503 platforms since *nix does not recognize CTRL and the right arrow held down
504 together. If you wish to enable this functionality on a *nix platform choose
505 a key and create one of these mappings (see |sql-completion-maps| for further
506 details on where to create this imap): >
507 imap <buffer> <your_keystroke> <C-R>=sqlcomplete#DrillIntoTable()<CR>
508 imap <buffer> <your_keystroke> <C-Y><C-\><C-O>:call sqlcomplete#Map('column')<CR><C-X><C-O>
509
510 Example of using column completion:
511 - Press <C-C>t again to display the list of tables.
512 - When the list is displayed in the completion window, press <C-Right>,
513 this will replace the list of tables, with a list of columns for the
514 table highlighted (after the same short delay).
515 - If you press <C-Left>, this will again replace the column list with the
516 list of tables. This allows you to drill into tables and column lists
517 very quickly.
518 - Press <C-Right> again while the same table is highlighted. You will
519 notice there is no delay since the column list has been cached. If you
520 change the schema of a cached table you can press <C-C>R, which
521 clears the SQL completion cache.
522 - NOTE: <C-Right> and <C-Left> have been designed to work while the
523 completion window is active. If the completion popup window is
524 not active, a normal <C-Right> or <C-Left> will be executed.
525
526 Lets look how we can build a SQL statement dynamically. A select statement
527 requires a list of columns. There are two ways to build a column list using
528 the SQL completion plugin. >
529 One column at a time:
530 < 1. After typing SELECT press <C-C>t to display a list of tables.
531 2. Choose a table from the list.
532 3. Press <C-Right> to display a list of columns.
533 4. Choose the column from the list and press enter.
534 5. Enter a "," and press <C-C>c. Generating a column list
535 generally requires having the cursor on a table name. The plugin
536 uses this name to determine what table to retrieve the column list.
537 In this step, since we are pressing <C-C>c without the cursor
538 on a table name the column list displayed will be for the previous
539 table. Choose a different column and move on.
540 6. Repeat step 5 as often as necessary. >
541 All columns for a table:
542 < 1. After typing SELECT press <C-C>t to display a list of tables.
543 2. Highlight the table you need the column list for.
544 3. Press <Enter> to choose the table from the list.
545 4. Press <C-C>l to request a comma separated list of all columns
546 for this table.
547 5. Based on the table name chosen in step 3, the plugin attempts to
548 decide on a reasonable table alias. You are then prompted to
549 either accept of change the alias. Press OK.
550 6. The table name is replaced with the column list of the table is
551 replaced with the comma separate list of columns with the alias
552 prepended to each of the columns.
553 7. Step 3 and 4 can be replaced by pressing <C-C>L, which has
554 a <C-Y> embedded in the map to choose the currently highlighted
555 table in the list.
556
557 There is a special provision when writing select statements. Consider the
558 following statement: >
559 select *
560 from customer c,
561 contact cn,
562 department as dp,
563 employee e,
564 site_options so
565 where c.
566
567 In INSERT mode after typing the final "c." which is an alias for the
568 "customer" table, you can press either <C-C>c or <C-X><C-O>. This will
569 popup a list of columns for the customer table. It does this by looking back
570 to the beginning of the select statement and finding a list of the tables
571 specified in the FROM clause. In this case it notes that in the string
572 "customer c", "c" is an alias for the customer table. The optional "AS"
573 keyword is also supported, "customer AS c". >
574
575
576 4.3.3 Procedure Completion: *sql-completion-procedures*
577
578 Similar to the table list, <C-C>p, will display a list of stored
579 procedures stored within the database. >
580
581 4.3.4 View Completion: *sql-completion-views*
582
583 Similar to the table list, <C-C>v, will display a list of views in the
584 database.
585
586
587 4.4 Completion Customization *sql-completion-customization*
588 ----------------------------
589
590 The SQL completion plugin can be customized through various options set in
591 your |vimrc|: >
592 omni_sql_no_default_maps
593 < - Default: This variable is not defined
594 - If this variable is defined, no maps are created for OMNI
595 completion. See |sql-completion-maps| for further discussion.
596 >
597 omni_sql_use_tbl_alias
598 < - Default: a
599 - This setting is only used when generating a comma separated
600 column list. By default the map is <C-C>l. When generating
601 a column list, an alias can be prepended to the beginning of each
602 column, for example: e.emp_id, e.emp_name. This option has three
603 settings: >
604 n - do not use an alias
605 d - use the default (calculated) alias
606 a - ask to confirm the alias name
607 <
608 An alias is determined following a few rules:
609 1. If the table name has an '_', then use it as a separator: >
610 MY_TABLE_NAME --> MTN
611 my_table_name --> mtn
612 My_table_NAME --> MtN
613 < 2. If the table name does NOT contain an '_', but DOES use
614 mixed case then the case is used as a separator: >
615 MyTableName --> MTN
616 < 3. If the table name does NOT contain an '_', and does NOT
617 use mixed case then the first letter of the table is used: >
618 mytablename --> m
619 MYTABLENAME --> M
620
621 omni_sql_ignorecase
622 < - Default: Current setting for|ignorecase|
623 - Valid settings are 0 or 1.
624 - When entering a few letters before initiating completion, the list
625 will be filtered to display only the entries which begin with the
626 list of characters. When this option is set to 0, the list will be
627 filtered using case sensitivity. >
628
629 omni_sql_include_owner
630 < - Default: 0, unless dbext.vim 3.00 has been installed
631 - Valid settings are 0 or 1.
632 - When completing tables, procedure or views and using dbext.vim 3.00
633 or higher the list of objects will also include the owner name.
634 When completing these objects and omni_sql_include_owner is enabled
635 the owner name will be replaced. >
636
637 omni_sql_precache_syntax_groups
638 < - Default:
639 ['syntax','sqlKeyword','sqlFunction','sqlOption','sqlType','sqlStatement']
640 - sqlcomplete can be used in conjunction with other completion
641 plugins. This is outlined at |sql-completion-filetypes|. When the
642 filetype is changed temporarily to SQL, the sqlcompletion plugin
643 will cache the syntax groups listed in the List specified in this
644 option.
645 >
646
647 4.5 SQL Maps *sql-completion-maps*
648 ------------
649
650 The default SQL maps have been described in other sections of this document in
651 greater detail. Here is a list of the maps with a brief description of each.
652
653 Static Maps
654 -----------
655 These are maps which use populate the completion list using Vim's syntax
656 highlighting rules. >
657 <C-C>a
658 < - Displays all SQL syntax items. >
659 <C-C>k
660 < - Displays all SQL syntax items defined as 'sqlKeyword'. >
661 <C-C>f
662 < - Displays all SQL syntax items defined as 'sqlFunction. >
663 <C-C>o
664 < - Displays all SQL syntax items defined as 'sqlOption'. >
665 <C-C>T
666 < - Displays all SQL syntax items defined as 'sqlType'. >
667 <C-C>s
668 < - Displays all SQL syntax items defined as 'sqlStatement'. >
669
670 Dynamic Maps
671 ------------
672 These are maps which use populate the completion list using the dbext.vim
673 plugin. >
674 <C-C>t
675 < - Displays a list of tables. >
676 <C-C>p
677 < - Displays a list of procedures. >
678 <C-C>v
679 < - Displays a list of views. >
680 <C-C>c
681 < - Displays a list of columns for a specific table. >
682 <C-C>l
683 < - Displays a comma separated list of columns for a specific table. >
684 <C-C>L
685 < - Displays a comma separated list of columns for a specific table.
686 This should only be used when the completion window is active. >
687 <C-Right>
688 < - Displays a list of columns for the table currently highlighted in
689 the completion window. <C-Right> is not recognized on most Unix
690 systems, so this maps is only created on the Windows platform.
691 If you would like the same feature on Unix, choose a different key
692 and make the same map in your vimrc. >
693 <C-Left>
694 < - Displays the list of tables.
695 <C-Left> is not recognized on most Unix systems, so this maps is
696 only created on the Windows platform. If you would like the same
697 feature on Unix, choose a different key and make the same map in
698 your vimrc. >
699 <C-C>R
700 < - This maps removes all cached items and forces the SQL completion
701 to regenerate the list of items.
702
703 Customizing Maps
704 ----------------
705 You can create as many additional key maps as you like. Generally, the maps
706 will be specifying different syntax highlight groups.
707
708 If you do not wish the default maps created or the key choices do not work on
709 your platform (often a case on *nix) you define the following variable in
710 your |vimrc|: >
711 let g:omni_sql_no_default_maps = 1
712
713 Do no edit ftplugin/sql.vim directly! If you change this file your changes
714 will be over written on future updates. Vim has a special directory structure
715 which allows you to make customizations without changing the files that are
716 included with the Vim distribution. If you wish to customize the maps
717 create an after/ftplugin/sql.vim (see |after-directory|) and place the same
718 maps from the ftplugin/sql.vim in it using your own key strokes. <C-C> was
719 chosen since it will work on both Windows and *nix platforms. On the windows
720 platform you can also use <C-Space> or ALT keys.
721
722
723 4.6 Using with other filetypes *sql-completion-filetypes*
724 ------------------------------
725
726 Many times SQL can be used with different filetypes. For example Perl, Java,
727 PHP, Javascript can all interact with a database. Often you need both the SQL
728 completion as well as the completion capabilities for the current language you
729 are editing.
730
731 This can be enabled easily with the following steps (assuming a Perl file): >
732 1. :e test.pl
733 2. :set filetype=sql
734 3. :set ft=perl
735
736 Step 1
737 ------
738 Begins by editing a Perl file. Vim automatically sets the filetype to
739 "perl". By default, Vim runs the appropriate filetype file
740 ftplugin/perl.vim. If you are using the syntax completion plugin by following
741 the directions at |ft-syntax-omni| then the |'omnifunc'| option has been set to
742 "syntax#Complete". Pressing <C-X><C-O> will display the omni popup containing
743 the syntax items for Perl.
744
745 Step 2
746 ------
747 Manually setting the filetype to 'sql' will also fire the appropriate filetype
748 files ftplugin/sql.vim. This file will define a number of buffer specific
749 maps for SQL completion, see |sql-completion-maps|. Now these maps have
750 been created and the SQL completion plugin has been initialized. All SQL
751 syntax items have been cached in preparation. The SQL filetype script detects
752 we are attempting to use two different completion plugins. Since the SQL maps
753 begin with <C-C>, the maps will toggle the |'omnifunc'| when in use. So you
754 can use <C-X><C-O> to continue using the completion for Perl (using the syntax
755 completion plugin) and <C-C> to use the SQL completion features.
756
757 Step 3
758 ------
759 Setting the filetype back to Perl sets all the usual "perl" related items back
760 as they were.
