SQL & PL/SQL :: Compress Already Existing - Partitioned Index
Jul 5, 2012Today I found myself in a situation where I needed to compress an already existing, partitioned index. First I issued an alter table to rebuild and compress the whole index:
SQL> ALTER INDEX MY_INDEX REBUILD COMPRESS;
ERROR at line 1:ORA-14086: a partitioned index may not be rebuilt as a wholeSo next I tried to rebuild compress one of the partitions:
SQL> ALTER INDEX MY_INDEX REBUILD PARTITION PART1 COMPRESS;
ERROR at line 1:ORA-28659: COMPRESS must be specified at object level first
Turns out that there is no way you can do a rebuild compress on partitioned indexes. I did not realize that until I stumbled across document 312843.1 on Metalink. It says the only way to compress a partitioned index is to drop it and recreate it (through 11.2).
My question is do we have any new feature in Oracle 11gR2 to rebuild partition indexes?

Existing Database (11.2.0.3) Can Be Upgraded As Pluggable Database And Plug It In CDB?
Sep 11, 2013I would like to know about oracle 12c. In 12c, when i read documents,i understood that one container DB(CDB) can contain upto 253 pluggable DB and this pluggable DB(PDB) is similar to our traditional database(pre 12c).
1) whether my existing database (11.2.0.3) can be upgraded as pluggable DB and plugged it in CDB?
2)i read that we can move from local data center model to cloud in this version. Is that mean that once PDB is ready, whether we can plug it in CDB using private cloud or public also possible?
3)If public cloud is possible, are both CDB and PDB accessed through cloud client only?If so, whether our user data that is available under PDB also moved to external place?

SQL & PL/SQL :: Check Existing Entries In Table
Apr 3, 2012I am abolute new in PL SQL and I am working on following topic:
I have to check if an entry exists in a table.
- if it exists ...... do something
- if not ...... simply go on
I tried the following:
select Count(*)from products p
where p.productNbr = temp_Nbr
Group By t.produkt;
I fetched the result into a variable entries
if entries > 0 .....
MY problem is the following:
If there are entries (entries>0) --> it works
If there are no entries, entries is not 0 but 'no data found' --> crash
I cannot work with Exceptions because this all happens in a Loop which must go on in both cases!

How To Add Sequence Column To Existing Table With Records
Dec 8, 2012I had created a new table named USERLOG with two fields from a previous VIEW. The table already consist of about 9000 records. The two fields taken from the VIEW, i.e. weblog_views consist of IP (consists of IP address), and WEB_LINK (consists of URL). This is the code I used,
CREATE TABLE USERLOG
AS
SELECT C_IP, WEB_LINK FROM weblog_views;
I want to add another column to this table called the USER_ID, which would consists of a sequence starting with 1 to 9000 records to create a unique id for each existing rows. I'm using Oracle SQL Developer: ODMiner version 3.0.04. I tried using the AUTO-INCREMENT option,
ALTER TABLE USERLOG
ADD USER_ID INT UNSIGNED NOT NULL AUTO_INCREMENT;
But I get an error with this,
Error report:
SQL Error: ORA-01735: invalid ALTER TABLE option
01735. 00000 - "invalid ALTER TABLE option"
Partitioning - Switch Partition Key On Existing Table?
Jan 23, 2011I recently started working with legacy code and noticed that some huge tables (5 years worth of data, don't have more details on me right now but can post later if needed) are partitioned based on time sequence number column while majority of queries are done based on time (different column). Queries performance is degrading and I'd like to try to modify partitioning and run some tests to evaluate performance improvement.
My only concern is with so much live data I have to come up with solution on how to switch partitioning with the least impact on applications running 24 x 7. Something you have done in the same situation and it worked?
