Execute a parameterized singleton SELECT statement

The instructions in the preceding section assume that the parameterized SELECT statement returns more than one row and, therefore, is associated with a cursor. If you know that at the time you write the program that the parameterized SELECT statement will always return just one row, you can omit the cursor and use the EXECUTE...USING SQL DESCRIPTOR...INTO statement instead of the OPEN...USING SQL DESCRIPTOR statement to specify parameter values from a system-descriptor area.
