SQL injection

I am testing an external script I wrote. I just discovered that the user can inject code into an UPDATE query through one of the form fields by entering clever values. For example:

UPDATE tablename SET field = '$_POST[var]'

So I need to check that the posted variable is clean. I'm not sure where to start and I want to cover all possibilities. Any hints, tips, advice?

thx

vB3 3.0.0
I don't suppose vB3 has a function for this?

It is not a VB3 engine, just a parsed copy!
