SQL::Translator::Producer::MySQL - MySQL-specific producer for SQL::Translator
Use via SQL::Translator:
use SQL::Translator; my $t = SQL::Translator->new( parser => '...', producer => 'MySQL', '...' ); $t->translate;
This module will produce text output of the schema suitable for MySQL. There are still some issues to be worked out with syntax differences between MySQL versions 3 and 4 ("SET foreign_key_checks," character sets for fields, etc.).
This producer takes a single optional producer_arg
mysql_version, which provides the desired version for the target database. By default MySQL v3 is assumed, and statements pertaining to any features introduced in later versions (e.g. CREATE VIEW) are not produced.
Valid version specifiers for
mysql_version are listed here
Normally the tables will be created without any explicit table type given and so will use the MySQL default.
Any tables involved in foreign key constraints automatically get a table type of InnoDB, unless this is overridden by setting the
mysql_table_type extra attribute explicitly on the table.
The producer recognises the following extra attributes on the Schema objects.
Set the list of allowed values for Enum fields.
Set the MySQL field options of the same name.
Use when producing diffs to indicate that the current table/field has been renamed from the old name as given in the attribute value.
Set the type of the table e.g. 'InnoDB', 'MyISAM'. This will be automatically set for tables involved in foreign key constraints if it is not already set explicitly. See "Table Types".
Please note that the
ENGINE option is the preferred method of specifying the MySQL storage engine to use, but this method still works for backwards compatibility.
Set the tables default charater set and collation order.
Set the fields charater set and collation order.
