39 | |
40 | =head1 DESCRIPTION |
41 | |
42 | This script uses SQL::Translator to parse the SQL schema and create a |
43 | Perl script that can connect to the database and dump the data as |
5a3f5c82 |
44 | INSERT statements (a la mysqldump) or MySQL's LOAD FILE syntax. You may |
45 | specify tables to "skip" (also using a "skiplike" regular expression) |
46 | and the generated dumper script will not have those tables. However, |
47 | these will also be options in the generated dumper, so you can wait to |
48 | specify these options when you dump your database. The database |
49 | username, password, and DSN can be hardcoded into the generated |
50 | script, or part of the DSN can be intuited from the "database" |
51 | argument. |
