We could not reproduce the problem. Please send to odac*devart*com a complete small sample that demonstrates the problem, including the script for creating database objects.

You can simply recreate this error editing your demo

C:\Programmi\CoreLab\Odac for Delphi 2007\Demos\Win32\OdacDemo\MultiQueries\Multiquery.pas

add one button to the form , and this code
procedure TMultiQueriesFrame.Button1Click(Sender: TObject);
begin
inherited;
OraQuery1.BreakExec;
end;

bye

Please check the type of the error that occurs. It is normal that EOraError with message 'ORA-01013: user requested cancel of current operation' occurs after you call the BreakExec method. So check if an access violation or EOraError occurs.

Yes I know that ORA-1013 is normal, but like in the thread title after the upgrade sometime when break a query i got an access violation

exception message : Access violation at address 00405048 in module 'T007.exe'. Read of address FFFFFFDC.
