NAME ^

DBIx::Class::Storage::DBI::mysql - Storage::DBI class implementing MySQL specifics

SYNOPSIS ^

Storage::DBI autodetects the underlying MySQL database, and re-blesses the $storage object into this class.

  my $schema = MyApp::Schema->connect( $dsn, $user, $pass, { on_connect_call => 'set_strict_mode' } );

DESCRIPTION ^

This class implements MySQL specific bits of DBIx::Class::Storage::DBI, like AutoIncrement column support and savepoints. Also it augments the SQL maker to support the MySQL-specific STRAIGHT_JOIN join type, which you can use by specifying join_type => 'straight' in the relationship attributes

It also provides a one-stop on-connect macro set_strict_mode which sets session variables such that MySQL behaves more predictably as far as the SQL standard is concerned.

STORAGE OPTIONS ^

set_strict_mode

Enables session-wide strict options upon connecting. Equivalent to:

  ->connect ( ... , {
    on_connect_do => [
      q|SET SQL_MODE = CONCAT('ANSI,TRADITIONAL,ONLY_FULL_GROUP_BY,', @@sql_mode)|,
      q|SET SQL_AUTO_IS_NULL = 0|,
    ]
  });
