Case Sensitive collation in MySQL
Is there any Collation type in MySQL which supports Case Sensitive. I had all type of collation in MySQL they开发者_运维技巧 all have _ci at the end of their name so they are case Insensitive collation.
According to MySQL Manual http://dev.mysql.com/doc/refman/5.0/en/charset-mysql.html you should be able to set collation to _cs
for case sensitivity. You can get a list of _cs
collations by executing SHOW COLLATION WHERE COLLATION LIKE "%_cs"
query
After a little research:
Apparently there are no utf8_*_cs
in MySQL (yet). If you need case sensitive collation for utf8 fields, you should use utf8_bin
. This will mess up ORDER BY
, but this can be fixed by ORDER BY column COLLATE utf8_general_ci

Try a collation ending in _bin
, such as latin1_bin
or utf8_bin
, depending on your character set.
The new version of MySQL (8.0.1 and higher) comes (finally) with a set of utf8mb4_*_0900_as_cs
collations.
