SQL::Translator::Parser::MySQL

NAME

SQL::Translator::Parser::MySQL − parser for MySQL

SYNOPSIS

  use SQL::Translator;
  use SQL::Translator::Parser::MySQL;
  my $translator = SQL::Translator−>new;
  $translator−>parser("SQL::Translator::Parser::MySQL");

DESCRIPTION

The grammar is influenced heavily by Tim Bunce’s "mysql2ora" grammar.

Here’s the word from the MySQL site (http://www.mysql.com/doc/en/CREATE_TABLE.html):

  CREATE [TEMPORARY] TABLE [IF NOT EXISTS] tbl_name [(create_definition,...)]
  [table_options] [select_statement]
  or
  CREATE [TEMPORARY] TABLE [IF NOT EXISTS] tbl_name LIKE old_table_name;
  create_definition:
    col_name type [NOT NULL | NULL] [DEFAULT default_value] [AUTO_INCREMENT]
              [PRIMARY KEY] [reference_definition]
    or    PRIMARY KEY (index_col_name,...)
    or    KEY [index_name] (index_col_name,...)
    or    INDEX [index_name] (index_col_name,...)
    or    UNIQUE [INDEX] [index_name] (index_col_name,...)
    or    FULLTEXT [INDEX] [index_name] (index_col_name,...)
    or    [CONSTRAINT symbol] FOREIGN KEY [index_name] (index_col_name,...)
              [reference_definition]
    or    CHECK (expr)
  type:
          TINYINT[(length)] [UNSIGNED] [ZEROFILL]
    or    SMALLINT[(length)] [UNSIGNED] [ZEROFILL]
    or    MEDIUMINT[(length)] [UNSIGNED] [ZEROFILL]
    or    INT[(length)] [UNSIGNED] [ZEROFILL]
    or    INTEGER[(length)] [UNSIGNED] [ZEROFILL]
    or    BIGINT[(length)] [UNSIGNED] [ZEROFILL]
    or    REAL[(length,decimals)] [UNSIGNED] [ZEROFILL]
    or    DOUBLE[(length,decimals)] [UNSIGNED] [ZEROFILL]
    or    FLOAT[(length,decimals)] [UNSIGNED] [ZEROFILL]
    or    DECIMAL(length,decimals) [UNSIGNED] [ZEROFILL]
    or    NUMERIC(length,decimals) [UNSIGNED] [ZEROFILL]
    or    CHAR(length) [BINARY]
    or    VARCHAR(length) [BINARY]
    or    DATE
    or    TIME
    or    TIMESTAMP
    or    DATETIME
    or    TINYBLOB
    or    BLOB
    or    MEDIUMBLOB
    or    LONGBLOB
    or    TINYTEXT
    or    TEXT
    or    MEDIUMTEXT
    or    LONGTEXT
    or    ENUM(value1,value2,value3,...)
    or    SET(value1,value2,value3,...)
  index_col_name:
          col_name [(length)]
  reference_definition:
          REFERENCES tbl_name [(index_col_name,...)]
                     [MATCH FULL | MATCH PARTIAL]
                     [ON DELETE reference_option]
                     [ON UPDATE reference_option]
  reference_option:
          RESTRICT | CASCADE | SET NULL | NO ACTION | SET DEFAULT
  table_options:
          TYPE = {BDB | HEAP | ISAM | InnoDB | MERGE | MRG_MYISAM | MYISAM }
  or      ENGINE = {BDB | HEAP | ISAM | InnoDB | MERGE | MRG_MYISAM | MYISAM }
  or      AUTO_INCREMENT = #
  or      AVG_ROW_LENGTH = #
  or      [ DEFAULT ] CHARACTER SET charset_name
  or      CHECKSUM = {0 | 1}
  or      COLLATE collation_name
  or      COMMENT = "string"
  or      MAX_ROWS = #
  or      MIN_ROWS = #
  or      PACK_KEYS = {0 | 1 | DEFAULT}
  or      PASSWORD = "string"
  or      DELAY_KEY_WRITE = {0 | 1}
  or      ROW_FORMAT= { default | dynamic | fixed | compressed }
  or      RAID_TYPE= {1 | STRIPED | RAID0 } RAID_CHUNKS=#  RAID_CHUNKSIZE=#
  or      UNION = (table_name,[table_name...])
  or      INSERT_METHOD= {NO | FIRST | LAST }
  or      DATA DIRECTORY="absolute path to directory"
  or      INDEX DIRECTORY="absolute path to directory"

A subset of the ALTER TABLE syntax that allows addition of foreign keys:

  ALTER [IGNORE] TABLE tbl_name alter_specification [, alter_specification] ...
  alter_specification:
          ADD [CONSTRAINT [symbol]]
          FOREIGN KEY [index_name] (index_col_name,...)
             [reference_definition]

A subset of INSERT that we ignore:

  INSERT anything

ARGUMENTS

This parser takes a single optional parser_arg "mysql_parser_version", which provides the desired version for the target database. Any statement in the processed dump file, that is commented with a version higher than the one supplied, will be stripped.

The default "mysql_parser_version" is set to the conservative value of 40000 (MySQL 4.0)

Valid version specifiers for "mysql_parser_version" are listed here
