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.

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

1`utf8mb4_bin` exists, too, since it's 2019 now :-) – artfulrobot Aug 10 '19 at 10:12

To convert utf8 value to charset latin1 and then use latin1_general_cs for like-comparison use: select ... convert(cast(convert(myfield using utf8) as binary) using latin1) COLLATE latin1_general_cs like '...' – jfx Jan 12 '23 at 10:27

Try a collation ending in _bin
, such as latin1_bin
or utf8_bin
, depending on your character set.
