TCustomSQLQuery.OnPostError property

Declaration

property OnPostError:;

Description

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

Event triggered when a post operation fails.

OnPostError is triggered when the Post method fails to post the changes in the dataset buffer to the underlying database, because the database engine reported an error. The event handler can be used to indicate what the response to the failed post operation should be. To this end, it gets the exception object passed to it (parameter E), and it can examine this object to return an appropriate action in the DataAction parameter. The following responses are supported:

daFail

The operation should fail (an exception will be raised).

daAbort

The operation should be aborted (edits are undone, and an EAbort exception is raised).

daRetry

Retry the operation.
