Обсуждение: select inside transactions

I had to revert the patch on pgSetBase.cpp (Rev4986) because to handle
the very special case of selects inside transactions when executed in a
single step (I'd recommend to execute them step by step) the standard
case of a query returning no data (e.g. drop table foo) didn't return
messages any more.

Yikes. I guess my disclaimer was well placed ;-)

Did you just revert it, or did you figure out a proper way of doing it?

Just reverted. Currently I don't see a proper way to implement it,
unless multiple output panes (as in isqlw) are implemented.

Bummer. I had that feeling - it seemed to easy :-(

You could try to store the last result (for later returning), and drop
it if a newer is detected. Please take care that return code of *all*
commands are reported.
