Hi George,

The pre-query event triggers every time the datasource is queried, just before the execution. I guess you want to run your custom procedure only once, just before the first execution of the datasource. If so, you can define a flag and check it in the pre-query event.

Best Regards,

Hi Ibrahim,

Ya, I tried that. Unfortunately I am not able get the name of the datasource that is invoking the pre-query. I need to know the datasource in pre-query so that I can make my procedure generic. Otherwise I will need to write as many pre-query procedures as there are datasources in my system.

Can you kindly help me with the right API for getting the datasource name that is invoking the pre-query?

George.

Hi George,

You can use api_application.getEvent().objectName_tx to get the name of the datasource that is invoking the pre-query.

Regards,
Ibrahim
