24 | |
25 | SQL::Translator::Parser::DBI::MySQL - parser for DBD::mysql |
26 | |
27 | =head1 SYNOPSIS |
28 | |
171fd49f |
29 | This module will be invoked automatically by SQL::Translator::Parser::DBI, |
30 | so there is no need to use it directly. |
34d79f68 |
31 | |
32 | =head1 DESCRIPTION |
33 | |
171fd49f |
34 | Uses SQL calls to query database directly for schema rather than parsing |
35 | a create file. Should be much faster for larger schemas. |
