Subject Re: [IBO] no return message of error in contraint of type check
Author Magni Thor Mortensen
Hello all,

I have noticed this as well.
if you do a "select from non_existing_table" for example and trap the
exception with the usual
"on e:exception do begin end;" e.message is empty
the onError event on IB_Connection and IB_Session does not work
correctly either
if you trap an exception elsewhere the onError event is never fired.
and the RaiseException variable inside the onError event seems to be ignored

this is only a problem if you use TIBOQuery, with TIB_Query it seems fine.

Example:
procedure test;
var
c : TIB_Connection;
q : TIBOQuery;
begin
c := TIB_Connection.Create(self);
q := TIBOQuery.Create(self);
q.IB_Connection := c;
c.DatabaseName := 'localhost:C:\Firebird\examples\EMPLOYEE.FDB';
c.Username := 'SYSDBA';
c.Password := 'masterkey';
q.SQL.Text := 'select * from non_exsisting_table';
try
q.Open;
except
on e:exception do begin
showmessage(e.message);
end;
end;
end;
