Hash Sub partitioning on Multiple column

user585870Jun 28 2015 — edited Jun 28 2015

Dear All ,


I have a hash sub partitioned on multiple columns for a table. Say sub partition by hash (column B, column C). Main partition is list on (column A).

 

Recently application introduced a query which is like,

Query 1:


Select * from TABLE_A

Where column A=201411

And column B =’MAUP’;

 

The above query 1 is not utilizing the sub partition and query execution is taking time.

 

Below is the earlier query which was benefitting partition & sub partition and this is running fine.


  Query 2:


Select * from TABLE_A

Where column A=201411

And column B = ’MAUP’

And column C = ‘GHRV’;

 

Can you please share the possible solution to handle this scenario.


Thanks in Advance
