SQL Server error “Procedure expects parameter”

Question

I\'m writing a login script. But when I want to check if user already exist the error:

Additional information: Procedure or function \'checkIfUserExcist\

Answer 1

You need to tell your SqlCommand that it uses a stored procedure - like this:

SqlCommand com = new SqlCommand("checkIfUserExcist", conn);
-- add this line here
com.CommandType = CommandType.StoredProcedure;
com.Parameters.AddWithValue("@username", username);
