Execute SQL query when a parameter changes

Ignition
1

Good morning.

In Ignition 8.0.14, I have a SQL Query in a “Query Tag”.
The query uses a parameter. I would like the query to run only when the parameter value changes to avoid unnecessary requests to the server.
So, the correct execution mode would be “Event Driven”?

Yes, that’s precisely how event driven works. A parameter change is the only way to trigger re-execution, as I understand it.
