SQL & PL/SQL :: Apply Redefinition And Create Range Partition And Hash Sub-partition?
Apr 3, 2013At present we have a non partitioned table.
Can we apply redefinition and create range partition and hash sub partition on it?
At present we have a non partitioned table.
Can we apply redefinition and create range partition and hash sub partition on it?
Can I add range sub partition to a hash partition table. Example like this.
CREATE TABLE test
(
test_id VARCHAR2(10 ) ,
test_TYPE VARCHAR2(5) ,
CREATE_DATE date
)
partition by hash (test_id, test_type)
Partitions 3
SUBPARTITION BY RANGE (CREATE_DATE);
When Tried, I am getting syntax error as invalid option.
I Know we can create dynamic partitions on table in oracle 11g. Is it possible to create normal partition and sub partition both dynamically.I have to create Normal partition range on date and sub partition list on Batch ID (varchar).

The table contains around 30 fields with 'MOBILE_NO' as primary key. most of the queries are having 'mobile_no' in where clause .I am planning to hash partition that table using mobile_no column as there is no other column available which can be used for partition.
clarify whether creating hash partition on such key would increase performance of data extraction as I have read on net that hash partitioning is not effective for performance tuning.
I have a existing non partition table with more than 100 million records,planning to re design using Hash partition.This table doesn't has any range column to do range partitioning.
Table has 40 columns with a Primary Key on two columns (guest_sales_Id ,Version Flag). guest_sales_Id is unique for entire table but with anopther column version Flag declared as Primary key.(Version Falg will have only two distinct values in entire table)
If i do hash partition,do i need to declare on two columns which are declared ad Primary key ?If i use only guest_sales_id to declare hash prtition any issues ?
I created the 32 hash partition on a fact table. Based on hash parititon technique it should evenly distribute data accross the different partition.But when i analyze the table and check the distribution its not at all even.

While trying partition exchange feature of Oracle with 2 hash partitioned tables, I come to know that I can't directly exchange partitions between 2 partitioned tables
I have two hash partitioned tables , so to move partition data from one table to another will include-
1) Exchange from partitioned table to non-partitioned table.
2) exchange from non-partitioned table to new partitioned table.
But I am not sure in which hash partition my data will go in new partitioned table (data need to be moved has single key value on basis of which tables are partitioned),
In my prod table few partition need to be added.
I tried below both syntax, but I am getting error
1)
Alter table STS.DNA_ACCESSION add PARTITION DNA_ACC_P143 VALUES LESS THAN (286000000);

I have a table partitioned by Range and subparitioned by hash.
i am issuing the following query .Bcos of security purposes i cannot post the full query.

When i use INDEX_SS hint in the query then only the partition scan is happening.

Performance while using the index is very very slow.Is there any way without using the index and just the partition full scan can be forced by using some hint..
I am trying to create a partitioned table so that a number (which date converted to number ) partition is created on inserting a new row for release_date column.
note that release_date column is having number data type (as per design) and people want to create an interval based partition on this.
They want data type NOT to be altered.
create table product(
prod_id number,
prod_code varchar2(3),
release_date number)
partition by range(release_date)
interval(NUMTOYMINTERVAL (1,'MONTH'))
(partition p0 values less than (20120101))
Script to add range partition automatically. This script should be running every month and add the partitions for next 3 months

I have partition based table one the basis of year month. And we have 8 local indexes on this table. Every month we have to create a new partition and load data into this partition and the volume of the data is around 14million and the load process is taking long time due to indexes. Is it possible to drop the indexes from particular partition?

How to find the size pf a partition in a partition table?I guess we need to query views like dba_tab_partitions but I am not very sure. will running dbms_stats.gather_table_stats('schema_name,'table_name,'partition_name')
View 3 Replies View RelatedI plan to create a copy of original partition table as below in source database DB1.
create table tblname as select * from sourcetab;
The purpose i am creating copy of original tables is i want to have same partition tables with data in target database DB2 (where the partition feature is diabled).
So i am creating copy of original partition tables ,will then create dump of duplicate tables using export method and then load the dump into target database using import.
Both source and target database are in different servers. Partition is disabled in target database. Partition table size is 2GB and it has 5 partitions P1,P2,P3,P4,P5 .Each partition is of size 100 MB. Count of partition table is 15805412
1.My question is would there be any problem while loading dump into target database (where the partition feature is not enabled)?
2.Is it feasible to create a copy of partition tables using below statements in same database ?
create table tblname as select * from sourcetab;
I need to create partition on the non partition table without dropping a table.
Range partition on stage tables and hash partition on fact tables.
I have an IOT table with partitioned on list. I have p1,p2 and p3 partitions. Now I would like to create a bitmap index on partition key.
I gave ALTER TABLE .. MOVE MAPPING TABLE;
But getting the below error,
ORA-28660: Partitioned Index-Organized table may not be Moved as a whole.
Is there any rule in documentation, when create partition index? For tables, it is said to partition when table is greater than 2GB, but what about index? WHat size it should have to partition?
