RE: [SQL] TRANSACTIONS and TCP/IP

Hi,

I would like to thank everyone for their responses.  I was able to get it
working by using the
various suggestions I received.  I had to turn off the ODBC drivers
autocommit and then
I could use the Tdatabase types' StartTransaction, Commit and RollBack
methods.

Thanks again everybody,

Barry
