Hi Pravin, The problem you are seeing here is probably related to the fact you have some other foreign keys that rely on the user_id column, Mysql will do everything to make your life miserable if you change the name of the column/size of type that has other constraints depend on it - and the error message is not exactly helpful here.
To fix your issue you will have to first drop the other constraints that depend on the column, then rename it, and then recreate constraints again. -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
