I can. I attach part of mylog output where the problem is described.
I try explain it in english and I hope you can understand.
Application call select on non-exists table. It's allocate stmt then
it prepare stmt. Then it call NumResultCols. Error raise in this
function but it return SQL_SUCCESS (I think this is right) and set
stmt status to STMT_PREMATURE. Then it call Execute. There is
clean_error so it return SQL_SUCCES and I think this is wrong>.
After it app call Fetch and it fail.
Application doesn't expect failure in Fetch after success execute.
I don't have source for app because it's commercial one. So I can't
change it's behaviour. I tried create table but app fails later.
When I patch psqlodbc it's doing what I expect. But I'm not sure
if it's good for all situations. I don't see so far.
The opposite one situation which I think about is execute twice or
more times with different binding parameters. So I add test status
to STMT_FINISHED. As I said I'm not sure if it's correct.
