In MariaDB, you can use the SHOW COLLATION administrative SQL statement to return all available collations in MariaDB.
Syntax
The syntax goes like this:
SHOW COLLATION [LIKE 'pattern' | WHERE expr]There are a lot of collations, so it helps to use the LIKE and/or WHERE clauses whenever you have an idea of the subset of collations you’re looking for.
Examples
Here are some examples to demonstrate.
The LIKE Clause
Here’s an example that uses the LIKE clause to return all collations that start with latin:
SHOW COLLATION LIKE 'latin%';Result:
+-------------------------+---------+------+---------+----------+---------+ | Collation | Charset | Id | Default | Compiled | Sortlen | +-------------------------+---------+------+---------+----------+---------+ | latin1_german1_ci | latin1 | 5 | | Yes | 1 | | latin1_swedish_ci | latin1 | 8 | Yes | Yes | 1 | | latin1_danish_ci | latin1 | 15 | | Yes | 1 | | latin1_german2_ci | latin1 | 31 | | Yes | 2 | | latin1_bin | latin1 | 47 | | Yes | 1 | | latin1_general_ci | latin1 | 48 | | Yes | 1 | | latin1_general_cs | latin1 | 49 | | Yes | 1 | | latin1_spanish_ci | latin1 | 94 | | Yes | 1 | | latin1_swedish_nopad_ci | latin1 | 1032 | | Yes | 1 | | latin1_nopad_bin | latin1 | 1071 | | Yes | 1 | | latin2_czech_cs | latin2 | 2 | | Yes | 4 | | latin2_general_ci | latin2 | 9 | Yes | Yes | 1 | | latin2_hungarian_ci | latin2 | 21 | | Yes | 1 | | latin2_croatian_ci | latin2 | 27 | | Yes | 1 | | latin2_bin | latin2 | 77 | | Yes | 1 | | latin2_general_nopad_ci | latin2 | 1033 | | Yes | 1 | | latin2_nopad_bin | latin2 | 1101 | | Yes | 1 | | latin5_turkish_ci | latin5 | 30 | Yes | Yes | 1 | | latin5_bin | latin5 | 78 | | Yes | 1 | | latin5_turkish_nopad_ci | latin5 | 1054 | | Yes | 1 | | latin5_nopad_bin | latin5 | 1102 | | Yes | 1 | | latin7_estonian_cs | latin7 | 20 | | Yes | 1 | | latin7_general_ci | latin7 | 41 | Yes | Yes | 1 | | latin7_general_cs | latin7 | 42 | | Yes | 1 | | latin7_bin | latin7 | 79 | | Yes | 1 | | latin7_general_nopad_ci | latin7 | 1065 | | Yes | 1 | | latin7_nopad_bin | latin7 | 1103 | | Yes | 1 | +-------------------------+---------+------+---------+----------+---------+
The WHERE Clause
Here’s an example that uses the WHERE clause to return all collations with a Sortlen of 2:
SHOW COLLATION WHERE Sortlen LIKE '2';Result:
+-------------------+---------+----+---------+----------+---------+ | Collation | Charset | Id | Default | Compiled | Sortlen | +-------------------+---------+----+---------+----------+---------+ | latin1_german2_ci | latin1 | 31 | | Yes | 2 | | cp1250_czech_cs | cp1250 | 34 | | Yes | 2 | +-------------------+---------+----+---------+----------+---------+
The AND Keyword
We can combine conditions with the AND keyword:
SHOW COLLATION
WHERE Sortlen LIKE '4'
AND Collation LIKE 'utf%';Result:
+---------------------+---------+-----+---------+----------+---------+ | Collation | Charset | Id | Default | Compiled | Sortlen | +---------------------+---------+-----+---------+----------+---------+ | utf8_thai_520_w2 | utf8 | 578 | | Yes | 4 | | utf8mb4_thai_520_w2 | utf8mb4 | 610 | | Yes | 4 | | utf16_thai_520_w2 | utf16 | 674 | | Yes | 4 | | utf32_thai_520_w2 | utf32 | 738 | | Yes | 4 | +---------------------+---------+-----+---------+----------+---------+
Return All Collations
To return all collations, simply remove all clauses:
