Procedure which searching UserId in all tables in databases
===

I want writing a procedure in MySQL which searching a UserId which we write example 

    call NEW_PROCEDURE(2) 

where 2 = UserId which we want search in all tables. I have an idea but I dont know how do it. First we must search all columns in database where column_name = UserId and Second we must search a value that we called in the procedure and UserId = our value

Can somebody help me ?
