| 718 | 1 " Vim indent file |
| 856 | 2 " Language: SQL |
| 3996 | 3 " Maintainer: David Fishburn <dfishburn dot vim at gmail dot com> |
| 4 " Last Change: 2012 Dec 05 | |
| 5 " Version: 3.0 | |
| 718 | 6 " Download: http://vim.sourceforge.net/script.php?script_id=495 |

| 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 | |
| 11 " fuctions and Oracle packages which contain stored procedures and | |
| 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: | |
| 23 " 3.0 (Dec 2012) | |
| 24 " Added cpo check | |
| 25 " | |
| 26 " 2.0 | |
| 27 " Added the FOR keyword to SQLBlockStart to handle (Alec Tica): | |
| 28 " for i in 1..100 loop | |
| 29 " |<-- I expect to have indentation here | |
| 30 " end loop; | |
