sql --> query for empty column

Hi,


I need to query for an empty column in a certain record.  
The column in question definitly has some empty entries.
I've tried <''>,<null>,<blanks>, and length(column). All
come back with no hits.



These records were created with sqlloader, if that has 
anything to do with it. The particlular column either
had a text string (varchar2) or nothing. What's the trick?
I suspect this is basic stuff; I'm new at this.



Solaris 2.51


Oracle 7.3.3



I'd appreciate any help,


crd
