Subject:Re: avoiding use of NullsA
View as plain text  
It seems that someone got bitten very hard in a soft area by a Null one 
day.
On a more practical level, Oracle recommended to design the table with 
the field where NULLs are to be expected at the end of the table, that 
saves a little space and two, as the use of indexes is invalidated in 
case of nulls its is better to place the important indexed fields toward 
the beginning of the table.
