when i try to create table an error is occured

its reason is character problem.

for example following query gives error :


word wtih problem is BabaAdı

ı -------------> Turkish Character

How can i recognize Turkish-character set ?????????????

sounds like a setup issue, what character set are you using?
you can set it via mysqld
a word of warning - that means all application using that server will us the same settigns, so its fine if your app is the sole user, but could cuase problems if not. if yo uare changing the character set yu may also want o consider changing the error messages in addition (my.cnf) and sort order.
