MySQL 5.7 Reference Manual  /  INFORMATION_SCHEMA Tables  /  The INFORMATION_SCHEMA COLLATIONS Table

24.3 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.

Notes

Collation information is also available from the SHOW COLLATION statement. See Section 13.7.5.4, “SHOW COLLATION Syntax”. The following statements are equivalent:

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

SHOW COLLATION
  [LIKE 'wild']
