114 | =head1 DESCRIPTION |
115 | |
116 | This script is part of the SQL Fairy project. It will try to convert |
117 | any source file for which it has a grammar into any format for which |
118 | it has a producer. |
119 | |
af2301d7 |
120 | If using "show-warnings," be sure to redirect STDERR to a separate file. |
44598b94 |
121 | In bash, you could do this: |
122 | |
123 | $ sql_translator.pl -f MySQL -t PostgreSQL --show-warnings \ |
124 | file.sql 1>out 2>err |
125 | |
126 | You can specify a parser or producer located in any module that Perl |
127 | knows about, allowing you to easily substitute your own. |
