You can change a query that already exists. The Rdbms Query View that opens when you edit an existing
query is, typically, the most convenient place to work with queries
as you are developing them because the query executes immediately
and the lower pane displays the results as soon as you click the Run button (or with some delay, depending on database
size and network connection speed). If there are errors in the query,
an error window opens with an error message.
The query you are working on already exists.
- Expand the , expand your rdbDatabase
and the Points folder it contains, right-click
the RdbmsPointQuery node, and click .
The
Rdbms Query View opens.
Note: This view executes on display. So as soon as you open this view the
saved query executes and displays results in the Query Results pane.
- To edit the saved query, select and work with the text
in the editor box (top box).
Each valid query entry in the
Sql property
returns a set of data. Two properties define the query:
Sql is a large text editor that displays
the text of the Query (if any).
Update Frequency displays when (in hours,
minutes, and seconds) the driver executes the query and updates the
control points.
- To test-run the query, click Run.
- To save the query for future use, click Save.
CAUTION: If you change (or refresh) the view without
clicking Save, any unsaved changes are lost.
No warning is given.
