Right, that is what I understood, I can't find a way to extract that data from the Tx property and I believe you are looking for a summary report like this:
SQL with variables:
..
Select 1 from dual
Select 2 from ***
select 3 from yyy
..
Maybe you can try to use CLWorstation or APMSQLserver, filter only dynamic sqls and/or the specific ones and then use awk/sed to extract the information as you need to
I hope this helps,
