there was a question coming up to my mind. Is there any possibility to use the current timestamp instead of a selected date in the Where Clause?

```

SELECT this, that
FROM here
WHERE start>='2010-07-01'
```

I thought it would be sth. like: start='now()' or curdate() or curtime().
Anything I found was that they're used in the Select Clause, but I need it in Where.

Any help is much appreciated.
