Thread: RE: [HACKERS] FYI: snapshot 4/28/1999 (fwd)

The weird thing is that the JDBC driver hasn't been sending an empty
string since 6.2.x. Starting from 6.3, I replaced the empty string with
a query to fetch the current DATESTYLE so the date and time code would
work properly.

It would be interesting to see if this patch fixes it however.

The following patch was posted this evening by Tom Lane that could fix
your
problem.  It fixed a similar problem I was having with ODBC.

If you don't have CVS access and don't want to wait for tonight's
snapshot,
here is the patch:

Peter, thought that you would like to know that the snapshot for
todaywill not allow a jdbc connection.  I don't know if this is a jdksecurity thing, or not.  The snapshot from Monday,
allows
connections.
I'm using jdk1.2.1, solaris 2.7, WorkShop Compilers 5.0 98/12/15
C
5.0

I'm unsure whether to blame my empty-query goof for the JDBC problem or
not.  You say Monday's snapshot was OK --- but I committed that booboo
on Sunday, so it should have been in Monday's snap.  Let us know whether
the problem is still there...
        regards, tom lane

Well Tom,   The patch fixed it.  With the snapshot from 4/28/1999, I can now
connect.

Thanks Peter, Michael & Tom.
