718 | 1 " Vim indent file |
856 | 2 " Language: SQL |
3996 | 3 " Maintainer: David Fishburn <dfishburn dot vim at gmail dot com> |
25973 | 4 " Last Change: 2021 Oct 11 |
5 " Version: 4.0 | |
718 | 6 " Download: http://vim.sourceforge.net/script.php?script_id=495 |
7 | |
8 " Notes: | |
9 " Indenting keywords are based on Oracle and Sybase Adaptive Server | |
10 " Anywhere (ASA). Test indenting was done with ASA stored procedures and | |
25773 | 11 " functions and Oracle packages which contain stored procedures and |
718 | 12 " functions. |
856 | 13 " This has not been tested against Microsoft SQL Server or |
718 | 14 " Sybase Adaptive Server Enterprise (ASE) which use the Transact-SQL |
15 " syntax. That syntax does not have end tags for IF's, which makes | |
16 " indenting more difficult. | |
17 " | |
18 " Known Issues: | |
19 " The Oracle MERGE statement does not have an end tag associated with | |
20 " it, this can leave the indent hanging to the right one too many. | |
3996 | 21 " |
22 " History: | |
25973 | 23 " 4.0 (Oct 2021) |
24 " Added b:undo_indent | |
25 " | |
3996 | 26 " 3.0 (Dec 2012) |
27 " Added cpo check | |
28 " | |
29 " 2.0 | |
30 " Added the FOR keyword to SQLBlockStart to handle (Alec Tica): | |
31 " for i in 1..100 loop | |
32 " |<-- I expect to have indentation here | |
33 " end loop; | |
34 " | |
718 | 35 |
36 " Only load this indent file when no other was loaded. | |
