OpenEdge Data Management: DataServer for Microsoft SQL Server

RDBMS Stored Procedure Details
3–12
DEFINE VARIABLE handle1 AS INTEGER NO-UNDO.
RUN STORED-PROC send-sql-statement handle1 = PROC-HANDLE
("SELECT name, address, city, state, postal_code
FROM customer WHERE credit_limit >= 500").
FOR EACH proc-text-buffer WHERE PROC-HANDLE = handle1:
DISPLAY proc-text-buffer.
END.
CLOSE STORED-PROC send-sql-statement WHERE PROC-HANDLE = handle1.
Example 3–1: Passing a SELECT statement as a parameter
Example 3–1 returns the name, address, city, state, and postal_code for all customers
whose max–credit is greater than or equal to $500. You must read the results into a buffer as
you would with a stored procedure called by an OpenEdge procedure. You can read the results
into the proc–text–buffer defined by OpenEdge as shown in the example above.
Alternatively, you can define your own buffer from within your data source that can accept
other data types as well as the CHARACTER data type.
With the Load-Result-Into option
Example 3–2 shows how to use the send-sql-statement with the LOAD-RESULT-INTO option. It
also shows that the PROC-STATUS phrase must be defined as part of the RUN STORED-PROC
statement because of the implicit CLOSE STORED-PROC that is associated with the
LOAD-RESULT-INTO phrase.
DEFINE VARIABLE res AS INTEGER NO-UNDO.
DEFINE VARIABLE tthndl AS HANDLE NO-UNDO.
CREATE TEMP-TABLE tthndl.
RUN STORED-PROCEDURE send-sql-statement LOAD-RESULT-INTO tthndl
res = PROC-STATUS (“SELECT * FROM customer”).
IF res THEN
DISPLAY “succeeded”.
DISPLAY stat.
Example 3–2: Using the send-sql-statement with the LOAD-RESULT-INTO
option
Also note in Example 3–2 that the PROC-STATUS phrase does not need an associated
PROC-HANDLE phrase to close the associated procedure because it is retrieved using the RUN
STORED-PROC statement; although the PROC-HANDLE is typically used after the execution of the
RUN STORED-PROC statement, it is not needed in this context because of the implicit procedure
close.
