Re: [cx-oracle-users] ORA-01036

[Anthony T. <ant...@gm...>]

Hi,

My only thoughts are that you are using that cursor for some other
queries besides the one shown here? Do you have threads running in
this application and you forgot to turn on threaded mode? Besides
those possibilities I can't think of anything else -- and the only
time I run into that exception is when my sql and my bind variables
don't match for some reason. It would be nice if Oracle told you
__which__ bind variable it didn't like as that would aid in debugging
the problem but unfortunately it does not. :-( Good luck!

Anthony
