OpenEdge Data Management: DataServer for Microsoft SQL Server

RDBMS Stored Procedure Details
3–28
Example 3–18 shows the basics of using an existing dynamic temp-table with the
TEMP-TABLE-PREPARE() method.
/* Calling a stored procedure, using an existing temp-table with temp table
prepare*/
DEFINE VARIABLE ttHndl AS HANDLE NO-UNDO.
CREATE TEMP-TABLE tt1Hndl.
ttHndl:ADD-NEW-FIELD(“custNum”, ”integer”).
ttHndl:ADD-NEW-FIELD(“name”, ”character”).
ttHndl:TEMP-TABLE-PREPARE(“ordX”).
RUN STORED-PROC send-sql-statement LOAD-RESULT-INTO ttHndl
(“select custNum,name from myDB.customer”).
Example 3–18: Using an existing dynamic temp-table with the
TEMP-TABLE-PREPARE ( ) method
Note the following points as they relate to Example 3–18:
• As a prerequisite for creating the code shown, the developer would need to define the
schema for the table.
• Once the temp-table schema begins preparation from the clear state, the temp-table must
be defined to the exact specifications for the result sets as generated by the RUN
STORED-PROC statement or send-sql- statement. Otherwise, the RUN STORED-PROC will end
in failure. Also, note the TEMP-TABLE-PREPARE must be called at the completion of the
temp-table definition associated with the stored procedure results.
Example 3–19 shows passing the handles of empty dynamic temp-tables to enable a MS SQL
Server DataServer to create schema based on the result-set schema.
/ *Calling a stored procedure, and using the EXTENT phrase to pass handles of
empty temp-tables to enable the MS SQL DataServer to create schema holder
definitions based on each temp-table’s result-set schema. */
DEFINE VARIABLE ttCustomer AS HANDLE NO-UNDO.
DEFINE VARIABLE ttHandle AS HANDLE NO-UNDO EXTENT 2.
DEFINE VARIABLE ttOrder AS HANDLE NO-UNDO.
CREATE TEMP-TABLE ttCustomer.
CREATE TEMP-TABLE ttOrder.
ttHand1e[1] = ttCustomer.
ttHand1e[2] = ttOrder.
RUN STORED-PROC send-sql-statement LOAD-RESULT-INTO ttHandle
(“Select * from customer; select * from order”).
