Re: timeout implementation issues

Jessica,

My reading of the JDBC spec would indicate that this is a statement
level property (aka query level) since the method to enable this is on
the Statement object and is named setQueryTimeout(). There is nothing I
can find that would indicate that this would apply to the transaction in
my reading of the jdbc spec.

thanks,
