718 | 1 " Vim indent file |
856 | 2 " Language: SQL |
3996 | 3 " Maintainer: David Fishburn <dfishburn dot vim at gmail dot com> |
4073 | 4 " Last Change: 2012 Dec 06 |
3996 | 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. | |

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; | |

49 " SQL is generally case insensitive, so this files assumes that | |

51 " an indent right, since the SQLBlockStart is used for those keywords | |
