Hello,

I'm trying to insert new row in a system catalog table and then I'd like
to retrieve this value in one command internally. I started new
transaction for insertion operation and commited that transaction. And
insert operation works well, but I give me server crash error. Could you
let me know how can I handle transactions for insertion and selection
sequentially in one command?

I think rather than starting and committing a new transaction, what you
want to do is CommandCounterIncrement() after inserting without messing
the transaction mechanism.

Thank you. At the first time, it works well. But if I try to do same
command again, it still give me a server crash error.
