TCustomSQLQuery.BeforeOpen property

Declaration

Description

Not described here; this is what TDataSet.BeforeOpen says of it:

Event triggered before the dataset is opened.

BeforeOpen is triggered before the dataset is opened. No actions have been performed yet when this event is called, and the dataset is still in dsInactive state. It can be used to set parameters and options that influence the opening process. If an exception is raised during the event handler, the dataset remains closed.
