I want to assign the results of an SQL ExecuteScalar to an int. Which is fine when the ExecuteScalar returns a value (i.e the paramater sent to the stored procedure caused the SELECT function to find a valid record).
BUT if the paramater does not pass the SELECT procedure a value that is already in the table the assignment to an int causes an exception (as no record was returned).
Can i do this without using a try/catch block?

you can't do it without using try catch or an if statement which in this case is the same.
