Partition reports

Question

Hello people
I have quite a lot of tables, with many partitions each:
SELECT table_name, partition_name
FROM user_tab_partitions
ORDER BY 1;
My partititions are in the following format:
P2009W01 -> weekly partitions
P2009M01 -> montly partitions
P2009Q01 -> quarterly partitions
P20090307 -> daily partitions
I need a report that will read the above formats (strings) and display a report of the partitins, if it is weekly, daily, monthly or quarterly
eg:
table_name partition_name period
quarterly_tab P2009Q01 Quarterly
monthly_tab P2009M01 Montly
So I suppose I have to do something: if th 5th character is Q , print quarterly, and so on.
Case, decode ?
Thank you in advance for your help

I would be more explicit across the whole sting, and thereby identify all the partitions not named properly
select  dtp.Table_Name
       ,dtp.Partition_Name
       ,case
          when dtp.Partition_Name like 'P____Q_' then
            'Quarterly'
          when dtp.Partition_name like 'P____M_' then
            'Monthly'
          when dtp.Partition_Name like 'P____W_' then
            'Weekly'
          when dtp.Partition_Name like 'P________' then
            'Daily'
          else
            'Unknown'
        end Partition_Type
from    dba_tab_partitions  dtp
where   dtp.Partition_Name  like 'P____%'
and     dtp.Table_Owner     =  :p_Schema
and     dtp.Table_name      not like '%$%'Edited by: bluefrog on Jul 2, 2010 2:27 PM
