25.6 The INFORMATION_SCHEMA COLLATIONS Table

The COLLATIONS table provides information about collations for each character set.

The COLLATIONS table has these columns:

  • COLLATION_NAME

    The collation name.

  • CHARACTER_SET_NAME

    The name of the character set with which the collation is associated.

  • ID

    The collation ID.

  • IS_DEFAULT

    Whether the collation is the default for its character set.

  • IS_COMPILED

    Whether the character set is compiled into the server.

  • SORTLEN

    This is related to the amount of memory required to sort strings expressed in the character set.

  • PAD_ATTRIBUTE

    The collation pad attribute.

Notes

Collation information is also available from the SHOW COLLATION statement. See Section 13.7.7.4, “SHOW COLLATION Statement”. The following statements are equivalent:

SELECT COLLATION_NAME FROM INFORMATION_SCHEMA.COLLATIONS
  [WHERE COLLATION_NAME LIKE 'wild']

SHOW COLLATION
  [LIKE 'wild']
