Re: odd behaviour of prepared statement - Mailing list pgsql-jdbc

Kevin-

It looks like you're preparing the statement before you tack on the last
piece after the order by, so the parser just sees "Order By" at the end of
the string with no fields following it.

BTW, since you're not passing any parameters in, it seems like you might as
well just execute this statement straight rather than going through
preparing it.
