   Consider this:  what is the definition of 'NULL' and how can anything   
   'equate' to that 'value'?   
      
   You want to use the 'IS NULL', not the '= NULL' construct.   
      
   (This is basic SQL - please consider reviewing your/an 'introduction to   
   SQL' documentation or book.  Things like this are not intuitive to the   
   uninitiated and will lead to frustration.)
