DBIx::Class::Storage::DBI::mysql(3pm) User Contributed Perl Documentation DBIx::Class::Storage::DBI::mysql(3pm)
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 = MyDb::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|,
]
});
