Whether Collate Latin1_General_CS_AS and Collate utf8_bin are same, well they are different the former is for Latin1 开发者_如何转开发charset and the latter is for utf8 charset but i wanted to know whether both of will do case sensitive and Accent sensitive match.

Actually just now i have migrated my database from sql server2000 to MySQL 5.2 and i have a password field which i want to compare with case sensitive and Accent sensitive in sql server that Collate Latin1_General_CS_AS is working fine but i want to know Collate utf8_bin is the replacement for that in MySQL or there are some other better ways to achieve the same.


I don't know SQL server and the collation you mention, but utf8_bin, being a binary collation, is indeed case and accent sensitive.

You don't necessarily need to have the entire database in that collation though - binary collations are not great at sorting. You can force a binary comparison in a non-binary collation (like utf8_general_ci) using the COLLATE keyword:

SELECT column FROM table WHERE password COLLATE utf8_bin = "abcäöü";
