Connect SQL form

Alternative: Starting in V5.3, if
your application needs to perform a simple save operation against an
external database, it is best practice to use the Connector and Metadata
Accelerator to configure access to the rows as an external class. When such
external access is configured for an external table, you can use the
Obj-Open, Obj-Browse, and other Obj- methods to interact with that table
through a class that represents it; you do not need to create SQL
connector rules. See About
generating connector rules.
However, you can still use the Save tab to
enter the SQL statement that saves an instance to the database.
However, you can still use the Open tab to enter a SQL statement that opens a single row in the database and copies its column values as properties onto a clipboard page. To execute the SQL statement on this tab, an activity uses the RDB-Open method.
As a best practice, include only one SQL statement on this tab. If your situation requires multiple statements, place one statement each in separate Connect SQL rules. Your activity can cause the statements to be executed in the desired sequence. STEWS TN 8/22/02 If your situation requires many statements executed in sequence, consider using a stored procedure.
If the SELECT
statement when executed
causes no rows to be retrieved, or more than one row to be
retrieved, the RDB-Open method produces a fail status, and no properties
are added to the step page. TURBT 10/21/02 R-5708?Complete the
Browse tab, not the Open tab, if you want to search the database in a way
that may result in none, one, or multiple matches.
The IBM DB2 data type DATE
does not
directly correspond to any Process Commander property type. Use syntax
similar to the following as a workaround: SR-7589 B-14387
SELECT TIMESTAMP(RPT_DATE, '00.00.00') AS ".RPT_DATE"
Properties retrieved by browsing an external database are not tracked for changes by Declare Expression processing.
