Interfacing with RDBMS stored procedures
defined in the temp-table that will receive the result set. No mapping exists between the
result set and the temp-table. Therefore, the first field defined in the temp-table
corresponds to the first column of the result set and so forth.
Additional temp-table examples
This section presents more examples that show various techniques to code
temp-tables.
Example 15 follows this initial explanation; the stored procedure myProc is comprised
of two fields—one is an integer and the other is a character, and a result set.
SELECT “myProc,” cust_num, cust_name FROM
Example 15: Temp-table code technique
Example 16 shows the basics of executing a call to a stored procedure using the
LOAD-RESULT-INTO functionality. Note that in this example, PROC-STATUS function is
not specified. Therefore, there is no possibility of a return value.
/* Calling a stored procedure, using the LOAD-RESULT-INTO phrase*/
DEFINE VARIABLE res AS INTEGER NO-UNDO.
DEFINE VARIABLE ttHndl AS HANDLE NO-UNDO.
DEFINE TEMP-TABLE ttl
FIELD f1 AS INTEGER
FIELD f2 AS CHARACTER.
ttHndl = TEMP-TABLE tt:HANDLE.
RUN STORED-PROC myProc LOAD-RESULT-INTO ttHndl (INPUT 1, OUTPUT res).

LOAD-RESULT-INTO functionality
Example 17 shows the basics of using an existing dynamic temp-table without the
TEMP-TABLE-PREPARE () method. In this instance, send-sql-statement is used
rather than a predefined stored proc. In contrast, the third example code that appears
later in this section shows the same approach, but explicitly defines the existing
dynamic temp-table with the TEMP-TABLE-PREPARE() method.
/* Calling a stored procedure, using an existing temp-table without temp table
prepare */
DEFINE VARIABLE ttHndl AS HANDLE NO-UNDO.
CREATE TEMP-TABLE ttHndl.
RUN STORED-PROC send-sql-statement LOAD-RESULT-INTO ttHndl
(“select * from customer”).

TEMP-TABLE-PREPARE ( ) method
