Table Access for NULL value Criteria

560426Feb 8 2007 — edited Feb 8 2007
When I try to execute an explain plan for a query having a criteria checking for NULL values,there is a full scan of tables.Is there any method where I can avoid the full scan and have an indexed scan.(P.S: There is an index created on the column used in the where clause)
