Effective or not? What kind of question is this? Further, use comment feature if you want to interact to some answer.

Effective or not? I am not sure what you are asking but hope if your db table contains unique userid/email you can change your query to
select * from mcs_User where userid=@userid
so that instead of reading all rows you can read only those with userid passed.
