Case Sensitive collation in MySQL

Posted by: admin November 1, 2017 Leave a comment

Questions:

Is there any Collation type in MySQL which supports Case Sensitive.
I had all type of collation in MySQL they all have _ci at the end of their name so they are case Insensitive collation. Thank you in advance.

Answers:

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.
