Class::DBI::DATA::Schema - Execute Class::DBI SQL from DATA sections
package Film.pm; use base 'Class::DBI'; # ... normal Class::DBI setup use 'Class::DBI::DATA::Schema'; Film->run_data_sql; __DATA__ CREATE TABLE IF NOT EXISTS film (....); REPLACE INTO film VALUES (...); REPLACE INTO film VALUES (...);
This is an extension to Class::DBI which injects a method into your class to find and execute all SQL statements in the DATA section of the package.
Using this module will export a run_data_sql method into your class. This method will find SQL statements in the DATA section of the class it is called from, and execute them against the database that that class is set up to use.
It is safe to import this method into a Class::DBI subclass being used as the superclass for a range of classes.
WARNING: this does not do anything fancy to work out what is SQL. It merely assumes that everything in the DATA section is SQL, and applies each thing it finds (separated by semi-colons) in turn to your database. Similarly there is no security checking, or validation of the DATA in any way.
There are undocumented arguments that will allow this module to translate the SQL from one database schema to another, and also to cache the result of that translation. People are relying on these, so they're not going to go away, but you're going to need to read the source and/or the tests to work out how to use them.
