select * from DBA_UNUSED_COL_TABS
where owner ='EQUIPMENT' and table_name = 'ETHRNT_VRTL_CNXN_HRLY_AGG_SWP';

Sep 7, 2012I have a table that has 2 columns of type nested table. Now in the purge process, when I try to truncate or drop a partition from this table, I get error that I can't do this (because table has nested tables). how I will be able to truncate/drop partition from this table? IF I change column types from nested table to varray type, will it work?
Also, is there any short method of moving existing data from a nested table column to a varray column (having same fields as nested table)?

View 2 Replies View RelatedCompressed Table - Drop Unused Column
Feb 9, 2012what happens if you mark a column unused in a compressed table and then alter table drop unused columns? We had a customer do this and Oracle threw a -3113 (end of communication) error. They did a system restore before contacting us and blew away any evidence in alert logs/trace files. They did this on a 400GB compressed table.
My question is, when you drop an unused column off a compressed table, does it uncompress? Where does this uncompression occur? In the instances default tablespace? In the tablespace configured for the table?
Basically, we are wondering whether the error was due to poor error-handling of the system running out of space during decompression and trying to see if we can reproduce it. This was on an 11.1.0.7 system.

View 12 Replies View RelatedDrop Statement On Table Taking Long Time
Sep 20, 2010We are firing a normal Drop command on our database and the database version is 10.2.0.4.The database is running on AIX v5.The command is taking more time than usual .
When i am monitoring the session i can see that a call is being made to procedure "aw_drop_proc".Could i ask you if this is something that is taking more time than usual.
We are not having any partitions on the nested tables .We have a pack of tables and we are dropping this pack through a procedure.The pack comprises of nested tables & normal tables.To drop a nested table it is taking around 6 seconds(Table with no rows) and a normal table(With no rows) it is taking 17 milli seconds.We have a partition on Normal table.
The same operation in windows is taking very less time when compared to AIX.

SQL & PL/SQL :: Unable To Drop Interim Table After Redefinition Process
May 11, 2012I performed the Table Redefinition process on one of my transaction tables. I wanted to redefine the existing table to a new table with partitions. Everything worked fine until i reached the last step where we had to drop the interim table. Now in between the redefinition , we created the interim table with partition along with the constraints and indexes and then atlast ran the "dbms_redefinition.finish_redef_table" proc to finish the redefinition.
And after that when I tried to drop the interim table , I am getting the below error message
"ERROR at line 1: ORA-02449: unique/primary keys in table referenced by foreign keys"
So this means all the constraints from my actual table were swapped with the interim table and hence I am getting this error.So is this a normal case or I have missed something while performing the redefinition? If thats normal then should i Just Drop table tablename CASCADE CONSTRAINTS?
