Connect SQL form - Completing the Open tab
You can 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. 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. 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.
DATE
does not directly correspond to any
Pega Platform
property type. Use syntax similar to the following as a workaround:
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.
Field | Description |
---|---|
Open SQL | Follow the guidelines in Data Mapping in
SQL. Enter a single SQL statement directly into the text box. Typically
this tab contains a SELECT statement, which may include the
WHERE and ORDER BY clauses. You can use an
EXECUTE statement (or equivalently a CALL
statement for Oracle) on this tab. The results of the RDB-Open method are properties and values added to the step page (of the step that contains the RDB-Open method) for the selected row. (If the Step Page column of that step is blank, the system uses the primary page of the activity.) |
Error Handler Flow |
Optional. Identify a flow rule that is to be started when this connector rule is started by a flow rule but fails when the Integrator shape throws a
ConnectorException
exception. The default flow rule
Work-.ConnectionProblem
provides one approach for handling such problems. See
Handling connector exceptions.

Test Connectivity | After you save this rule, you can click to confirm connectivity to the database. No database operations are performed. See More about Connect SQL rules. |
