Chapter 3: RDBMS Stored Procedure Details Without the Load-Result-Into option You use the RUN STORED–PROC statement with the send–sql–statement option and pass the Transact-SQL statements as a parameter. The syntax of the statement must be valid Transact-SQL syntax. Example 1 shows how this code passes a SELECT statement as a parameter. Note: The SQL statement(s) passed to the send-sql-statement stored procedure is not limited to the 32,000 bytes of a OpenEdge CHARACTER field. To pass SQL of greater size, store the SQL text in a LONGCHAR field and pass that as a parameter to the send-sql-statement stored procedure. 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 1: Passing a SELECT statement as a parameter Example 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 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 2: Using the send-sql-statement with the LOAD-RESULT-INTO option 130 OpenEdge Data Management: DataServer for Microsoft SQL Server
Run Stored-Procedure details Also note in Example 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.
