SQL::Translator::Producer::MySQL(3)

NAME
SQL::Translator::Producer::MySQL - MySQL-specific producer for SQL::Translator

SYNOPSIS
Use via SQL::Translator:

  use SQL::Translator;

  my $t = SQL::Translator->new( parser => '...', producer => 'MySQL', '...' );
  $t->translate;

DESCRIPTION
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.).

ARGUMENTS
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

  Table Types
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.

  Extra attributes.
The producer recognises the following extra attributes on the Schema objects.

field.list
    Set the list of allowed values for Enum fields.

field.binary, field.unsigned, field.zerofill
    Set the MySQL field options of the same name.

field.renamed_from, table.renamed_from
    Use when producing diffs to indicate that the current table/field has been renamed from the old name as given in the attribute value.

table.mysql_table_type
    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.

table.mysql_charset, table.mysql_collate
    Set the tables default character set and collation order.

field.mysql_charset, field.mysql_collate
    Set the fields character set and collation order.
