The constants are the stub (SELECT and FROM clauses etc) and the tail (ORDER
BY clause) of the SQL stament, which you need so you can patch the WHERE
clause between them. You can mock up a query, and swith it to SQL View (View
menu) to see an example of the statement you are trying to create.
The IsNull() has to wrap around the name of an unbound control (text box) on
your form.
The extra quotes are intended exactly as they are.
