I MariaDB kan du bruge SHOW COLLATION administrativ SQL-sætning for at returnere alle tilgængelige sorteringer i MariaDB.
Syntaks
Syntaksen ser sådan ud:
SHOW COLLATION [LIKE 'pattern' | WHERE expr]
Der er mange sorteringer, så det hjælper at bruge LIKE og/eller Hvor klausuler, når du har en idé om den undergruppe af kollationer, du leder efter.
Eksempler
Her er nogle eksempler til demonstration.
LIKE Klausul
Her er et eksempel, der bruger LIKE klausul for at returnere alle sammenstillinger, der starter med latinsk :
SHOW COLLATION LIKE 'latin%';Resultat:
+-------------------------+---------+------+---------+----------+---------+ | 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 | +-------------------------+---------+------+---------+----------+---------+
HVOR Klausul
Her er et eksempel, der bruger WHERE klausul for at returnere alle sammenstillinger med en Sortlen af 2 :
SHOW COLLATION WHERE Sortlen LIKE '2';Resultat:
+-------------------+---------+----+---------+----------+---------+ | Collation | Charset | Id | Default | Compiled | Sortlen | +-------------------+---------+----+---------+----------+---------+ | latin1_german2_ci | latin1 | 31 | | Yes | 2 | | cp1250_czech_cs | cp1250 | 34 | | Yes | 2 | +-------------------+---------+----+---------+----------+---------+
AND Søgeord
Vi kan kombinere betingelser med AND søgeord:
SHOW COLLATION
WHERE Sortlen LIKE '4'
AND Collation LIKE 'utf%';Resultat:
+---------------------+---------+-----+---------+----------+---------+ | 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 | +---------------------+---------+-----+---------+----------+---------+
Returner alle sorteringer
For at returnere alle sammenstillinger skal du blot fjerne alle klausuler:
