Thanks for the help. You are right on the money. However, I am getting the data as strings and I do not know what I will get. I get hundreds of thousands of them and I have no idea what they would look like.
I might get any string. couple of examples: select 1 + 1 + 1 + 1 from dual select 1 + (2 - 3)/4 + 5 / 4 + (6 + 7) / ( 5 + 5 + 0) So my requirement is different. When I use bind variables, either I use a bind variable for each literal and it will work, or use one bind variable for all literals and then all I will get back is one of the above string in the result set. The best answer is tht programmer should calculate the data as it comes in based on the token he gets and when he/she parses the data coming from the table. This might take place eventually. Right now I am trying to reduce huge library cache and shared pool contentions by elimating literal non-shared SQL. I come from C/C++/Pro*C development environment and I can not imagine ever using sys.dual to do arithmatic.
