Hi I am running a query against Oracle Table which is partition locally. All index are also partition locally and I had index on table1 column name COl1. Table is partition by ID,dateofBirth column Now when I running select * from table1 where col1=12345; Is there advantage I will get on the above query which is partitioned but not with Col1. Is there any disadvantage of using partition in this case. The requirement for partition is to delete data when it is more that 1 yr old and each month partition can have 10-20G data. thanks Sanjay __________________________________ Do you Yahoo!?
