Re: setFetchSize() bug - Mailing list pgsql-jdbc

Hi Felipe,

Your SQL DDL does not match your patch.

Nevertheless, I was able to reproduce your problem and tested Kim's
solution with the attached patch.  It indeed solves the problem.

We will try and make a test case based on your example.
Thanks for sending it.

Regards,
Fernando

data,as the error ocurrs when you call ResultSet.next()
