Notice that after we specify the SalesOrderHeader table in the FROM clause, we then include the CROSS APPLY keywords, following by the function, with the SalesOrderID column passed in as the parameter value. Is there a way to stop the function from being executed when a NULL is passed in as a parameter value?” “I’m creating a scalar function that will be used against a column that contains multiple NULL values. Should I create a stored procedure or a user-defined function?” The query will aggregate a subset of values based on an input parameter and return the aggregated value as a column in the query results.
