EDatabaseError not raised

Post by LHSoft » Wed 29 Jun 2016 13:24

I tried to open a table where one field missing in table of Database.
Data.DB correctly raises the EDatabaseError in

Code: Select all

procedure DatabaseError(const Message: string; Component: TComponent = nil);
but this error does not arrive in your TLiteConnection.onError.

Shouldn't be that handled in OnError of TLiteConnection?

best regards

If the number of fields or their types don't match, then the error is generated not by the database, but by Delphi using a usual method Raise. Therefore the onError event doesn't occur, since it works with errors generated by the database. If you need to handle this error, you can use a try...except block.
