Truncate / Drop Partitions In Table Having Nested Table Columns
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)?

PL/SQL :: How To Truncate Data In Table Partitions
Aug 9, 2013I couldn't either DROP or TRUNCATE the table partitions that were created. Here are the DDLs and DMLs I'm using.
Create table student(no number(2),name varchar(2)) partition by range(no) (partition
p1 values less than(10), partition p2 values less than(20), partition p3 values less
than(30),partition p4 values less than(40));
Insert into student values(1,'a');
Insert into student values(11,'b');
Insert into student values(21,'c');
Insert into student values(31,'d');
When I do the following query, it returns data.
SELECT * FROM STUDENT PARTITION(p1);
But, when I try to perform any of the following queries, it says invalid partition name.
ALTER TABLE STUDENT DROP PARTITION p4;
ALTER TABLE STUDENT TRUNCATE PARTITION p3;
I am using Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit

View 6 Replies View RelatedPL/SQL :: Index-Organized Table Truncate Vs Lock / Stage / Drop / Recreate?
Apr 24, 2013I ran into an issue in a project where a function is recreating an index-organized table by doing:Table Structure:
CREATE TABLE table_iot(
...)
ORGANIZATION INDEX
OVERFLOW ...;
Recreate Steps:
1) Populate global temporary staging table (gtt) with data
-- where gtt is staging for target index-organized table (iot)
2) Lock the target index-organized table (iot)
3) Copy old iot data to gtt
-- gtt now contains old and new data
4) Create new index-organized table (iot2) from gtt
-- iot2 now contains old and new data
[code]...
Because index-organized tables are primarily stored in a B-tree index, you can encounter fragmentation as a consequence of incremental updates. However, you can use the ALTER TABLE...MOVE statement to rebuild the index and reduce this fragmentation.The following statement rebuilds the index-organized table admin_docindex:
ALTER TABLE admin_docindex MOVE;

Export/Import/SQL Loader :: Import To New Table That Has Additional Fields
Dec 22, 2012I am trying to migrate a table to a new table that has the field sequence changed and also has a new field added. My main question is if it is possible to have datapump add values to the new field in the target table.For example:
-original table has fields a, b, d, c
-new table has fields b, c, d, a, e
I want to load the new table and also include adding values for field e. In this case, field e is a year field, so it should be loaded with '2012'..Does datapump have the ability to do this? Is reorganizing the fields going to cause me any problems? We are on oracle version 11.2.0.3

Truncate Partition From PL/SQL Package
May 8, 2013I have an Oracle Package with a procedure in which
package with a procedure in which there is a truncate partition, ALTER TABLE table_name TRUNCATE partition_name DROP STORAGE and the all is run with an EXECUTE IMMEDIATE 'alter table ...' .
The point is that the procedure in the package is started from another DB via DB Link (schema USER1) and doesn't work because of lack of privileges.
Instead, if the same procedure is started as a procedure, standalone, not in the package but from the same user (USER1) it works perfectly.
Don't understand why and which privileges must give to the user to run the procedure from inside the package.
