Re: Select after insert to the unique column

Thank you for your answer. I think it's very interesting behaviour. Is
it a feature or bug ?

I have try this my jUnit test for another DB systems (e.g. Oracle 9i,
MS SQL Server 2000, MySQL, DB2, Sybase, SAP DB) and it works for each of
these databases (it was possible tu run next command successfully after
an exception occured before).

With baset regards,
