13.7.5.5. SHOW COLLATION Syntax

SHOW COLLATION    [LIKE 'pattern' | WHERE expr]

This statement lists collations supported by the server. By default, the output from SHOW COLLATION includes all available collations. The LIKE clause, if present, indicates which collation names to match. The WHERE clause can be given to select rows using more general conditions, as discussed in Section 20.32, "Extensions to SHOW Statements". For example:

mysql> SHOW COLLATION LIKE 'latin1%';+-------------------+---------+----+---------+----------+---------+| Collation         | Charset | Id | Default | Compiled | Sortlen |+-------------------+---------+----+---------+----------+---------+| latin1_german1_ci | latin1  |  5 |         |          |       0 || latin1_swedish_ci | latin1  |  8 | Yes     | Yes      |       0 || latin1_danish_ci  | latin1  | 15 |         |          |       0 || latin1_german2_ci | latin1  | 31 |         | Yes      |       2 || latin1_bin        | latin1  | 47 |         | Yes      |       0 || latin1_general_ci | latin1  | 48 |         |          |       0 || latin1_general_cs | latin1  | 49 |         |          |       0 || latin1_spanish_ci | latin1  | 94 |         |          |       0 |+-------------------+---------+----+---------+----------+---------+

The Collation and Charset columns indicate the names of the collation and the character set with which it is associated. Id is the collation ID. Default indicates whether the collation is the default for its character set. Compiled indicates whether the character set is compiled into the server. Sortlen is related to the amount of memory required to sort strings expressed in the character set.

To see the default collation for each character set, use the following statement. Default is a reserved word, so to use it as an identifier, it must be quoted as such:

mysql> SHOW COLLATION WHERE `Default` = 'Yes';+---------------------+----------+----+---------+----------+---------+| Collation           | Charset  | Id | Default | Compiled | Sortlen |+---------------------+----------+----+---------+----------+---------+| big5_chinese_ci     | big5     |  1 | Yes     | Yes      |       1 || dec8_swedish_ci     | dec8     |  3 | Yes     | Yes      |       1 || cp850_general_ci    | cp850    |  4 | Yes     | Yes      |       1 || hp8_english_ci      | hp8      |  6 | Yes     | Yes      |       1 || koi8r_general_ci    | koi8r    |  7 | Yes     | Yes      |       1 || latin1_swedish_ci   | latin1   |  8 | Yes     | Yes      |       1 |...
