MySQL's MD5 hash is incorrect

问题

PHP's md5("123123") gives me a correct value of 4297f44b13955235245b2497399d7a93, while mysql's

select md5("123123");

gives me '6e9abeea535938c496a261b3b39c0d79'.

Why would this happen ? does this have anything to do with mysql server incoding? I kinda lost it, help much appreciated!

Thank you!

回答1:

6e9abeea535938c496a261b3b39c0d79 is the value of md5("132123"),so I think you have a type mistake.

回答2:

I get the same value from mysql and php. Might have something to do with multi-byte characters?
