hi all

i need ur help to write a query. please cosider the following scenario:

There is a table having colums (Attribute, Value) and data:
Attribute Value
a1 1
a2 2
a3 3.2
a4 a1*a2+a3
a5 a3 - a1

is it possible to write a query which will bring:
a1 1
a2 2
a3 3.2
a4 5.2
a5 2.2

Meaning the same column (Value) contains the numeric values as well as the formulas. There can be any number of operands, and all kind of possible operators.

Waiting for a response.
