Are there any OR's in the WHERE clause? If so, you might need to use
parentheses to get the right result. For instance: 

  WHERE condition1 OR condition2 AND condition 3

...will be unpredictable as to what it will retrieve. It could
alternatively be interpreted in either of these two ways: 

  WHERE (condition1 OR condition2) AND condition 3
  WHERE condition1 OR (condition2 AND condition 3)

The parentheses are essential to insure that it gets interpreted in
the way you want it to be interpreted.
