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