Dynamic conditions

Question

Hello.

I have a small software where i need to retrieve a conditional string from database and then check this condition in code.

For instance, i store in database string like this:

x>9&&y==1

In code, I want to replace x and y with values, for instance:

x=5

y=1

and then execute

if(5>9&&y==1)

   // do something

Anyone have an idea how to do so?

Thanks in advanced!
