NULLS

I am finding results are not coming back out of DLZ if certain fields  
are not NULL.  However, looking at the mysql query log, and the WHERE  
condition, I can not see that it matters why the non SOA records may  
have non NULL values in ttl, serial, etc.

Can someone help me understand this one?
