Subj:   COMPRESS on NULL Values.
 
From:   Chakinala, Raju

Help me understand "COMPRESS" clause on columns. Does Teradata compress 'null' values by default for columns that are not defined any other values for compression?

I understood that null values are compressed if column defined with COMPRESS or COMPRESS ('value1','value2',.), but I am not sure above case.


Thanks,
