To access rows returned in a result set, use the FETCH statement the same way you use it for cursors. The FETCH statement can be executed after any successful EXECUTE statement for a procedure that returns a result set.
Example
FETCH emp_proc INTO :emp_name_var;
Using FETCH after EXECUTE
Following an EXECUTE statement for a procedure, you can use the FETCH statement only to access values produced by the SELECT statement in the database stored procedure.
Since PowerBuilder cannot determine at compile time what result set will be returned when a database stored procedure executes, you must code FETCH statements so that the stored procedure exactly matches the format of the result set during execution. Assume you coded the second FETCH statement in the example above as:
FETCH emp_proc INTO :var1, :var2, :var3;
The statement compiles without errors. However, you will get an execution error indicating that the number of columns in the FETCH statement does not match the number of columns in the result set.
