parameter count mismatch in parameterized query

Question

I am using quite a lot of parameterized queries in my code for performance reasons. In short, some of them work, some don\'t.

I initialize the query during construction

Answer 1

Usually this error means that the SELECT/UPDATE query itself is incorrect. You did not give the schema of the database so it's not possible to pinpoint which one. So one or more of somevalue, sometable, one_feature, or second_feature is not in the database/table.
