Grammars
The grammars have been pulled from the following sources:
| Grammar | Last Retrieved | URL |
|---|---|---|
| MySQL | 2020/08/01 | https://github.com/mysql/mysql-workbench/tree/8.0/library/parsers/grammars |
| T-SQL | 2021/03/03 | https://github.com/antlr/grammars-v4/tree/master/sql |
| PL/SQL | 2021/03/03 | https://github.com/antlr/grammars-v4/tree/master/sql |
| PL/pgSQL | 2021/03/03 | https://github.com/pgcodekeeper/pgcodekeeper/tree/master/apgdiff/antlr-src |
We generate directly from the grammars supplied by those sources and make no modifications to them (this makes it easier to stay up to date). Some grammars use in-line code or base classes that must be added in after generating the parsers and lexers. Instructions for individual grammars are described in the Building section.
Are our grammars out of date?
