I have a range date partition table month wise which i want to truncate the partition and load for each month data i get from source.
How can i get the partion name based on data value.
e.g
source data
SALES_IDSALES_DT
101/02/2008
101/03/2008
101/04/2008
101/05/2008
target table has same structure as source but has more data but i want to delete only those which is coming from source if it is there in target and then load. so i want to get partition name so that i can truncate and load them.
I'm using Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production and TNS for Linux: Version 11.2.0.3.0 - Production.Requirement is to create a script to add a LIST partition to some selected tables in a schema (tables do not have data, they are not partitioned). There are about 300 such tables (can vary) and their names are maintained in a separate table. Example -Existing table
-CREATE TABLE test_part(id number (2), name varchar2(20), audit_userid number (9)); Expected table -CREATE TABLE test_part(id number (2), name varchar2(20), audit_userid number (9)) PARTITION BY LIST (audit_userid) (PARTITION p1_audit_userid VALUES (1));
Ultimate goal is to add more partitions based on the amount of data to be populated.
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 truncate the partition based on the given input. I've below table partitioned on dt field. How can i truncate the whole partition which contain the date 2013/04/30.
CREATE TABLE TST_SUMMARY ( CUST_ID NUMBER(38) NOT NULL ,
i am trying to create Procedure which will create the partitions based on the other table date values one per each day.
CREATE OR REPLACE PROCEDURE PARTITION_TEST(PART_DATE_TABLE IN VARCHAR2, TABLE_NAME IN VARCHAR2,SCHEMA_NAME IN VARCHAR2) AS V_PART_NM VARCHAR2(20); V_PART_CNT NUMBER; V_DATE DATE; V_SCHEMA_NAME VARCHAR(15);
[Code]..
It is not creating the partitions and even not giving any errors.
I need to partition a existing table based on varchar2 field (which is actaully date value but storing as character in the table). Using below statement for creating table, but getting error.
How can we partition a table based on date if it does not have a date column.
Actually I have to compare two tables on daily basis and fetch few rows from those two tables and enter it to a third table.But both these tables does not have a date column.
I am confused if i need to alter those tables and add date column or if there is some way in which i can compare the data from the two tables for that particular day only and not the whole table data.
i have table with range partition and list sub-partition..can i add one more list sub-partition if it is not possible , i have to drop first sub-partition.
Let us say, if i enter empno 10 (which is not there in database) in FIND Screen --> press FIND Button, it's showing up 'QUERY CAUSED NO RECORDS', Till this point it's working fine;. But after this, if i press CTR+F11 in block A, it's not pulling records. only this case it's not pulling records.
But if i enter something else in FIND Screen, if it returns any data, then if i press CTR+F11,it's pulling all records.
why it's failing to pull records if i try to query data in first case only.
I have table and it will contain huge data, so we have implemented as partitioned table. Every day when we load data into table there will be one partition created by the ETL Process by default with the Date Column(day wise). Now we may receive data for the previous days as well(Date column in table will have the date associated to the Data). No i would like the data should be inserted into partition which assocites to its own date.
I have a range partitioned table with one lob column. Each partion is on a separate tablespace except two partitions which are on same tablespace. Now I want to move a partition from one tablespace to another tablespace along with lob data. By using a simple alter table move partition will also move the lob data or there is some special procedure to adopt.
We would like to remove the partitions from a particular table. The table in question has 12 partitions. Based on some initial investigation, I've come up with the following options. because the table we going to remove partition will have millions of records so on considering the db downtime we are looking for a alternative way. Is there a better way?
Copy data into another table, drop all partitions, then copy the data back into the original table Copy data into another table, drop the original table, then rename the new table and rebuild the indexes.
I have 2 tables with same no of column and range partition based on date.At the end of month i want to copy the data of one table to another table.Instead of copy the data i want to copy the data of one partition completely to another table partition ..
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).
I have a table that partitioned into six partitions. each partitions placed in different table space and every two table space placed it on a different hardisk
when I will do query select with the non-partition keys condition, how the search process ? whether the sequence (scan sequentially from partition 1 to partition 6) or partition in a hardisk is accessed at the same time with other partition in other hardisk. ( in the image, partition 1,4 accessed at the same time with partition 2,5 and 3,6)
I have a staging table with 70 million rows and nearly 90 columns. We just want to verify and perform some validations on the data and then move this data to final tables. There staging table has a primary key in it.
We are planning to create the final table in following ways.
1. Create n number of final tables. 2. Create n number of final tables with partitions based on the primary key value in staging table. 3. Create single final table with partition based on the primary key value staging table.
how to get the output in below format. Count how many times each file is selected in a month.

What i want is I want the data which account is having more than 5 subaccounts within the last one month. Also need data with other date criteria like last 100 days if more than10 sub accounts. need single query.
Having more than 8lacks in my database. i wrote the query but it is taking much time and didnt give the data even after 14 hours.
My query is : select * from table a where account in (select account from table b where b.subaccount=a.subaccount and b.date>=sysdate-35 group by b.account having count(b.subaccount)>5) union select * from table a where account in (select account from table b where b.subaccount=a.subaccount and b.date>=sysdate-100 group by b.account having count(b.subaccount)>10)
how to retrieve the Subaccounts which satisfies my requirements.
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.

Activity1 Structure Which I have Done Partitioning When I insert data from Activity to Activity1 it gives that error ORA-14400: inserted partition key does not map to any partition what I am doing wrong
CREATE TABLE ACTIVITY1( ACTIVITY_TYPE CHAR (1) NOT NULL, ACTIVITY_DATE DATE DEFAULT sysdate NOT NULL, ACTIVITY_ON VARCHAR2 (30) NOT NULL, REFERENCE_NO VARCHAR2 (19),

When I am trying to insert record from tbl_mittal into tbl_temp table. I am facing "ORA-14400: inserted partition key does not map to any partition" error
SQL> insert into tbl_temp select * from tbl_mittal; insert into tbl_temp select * from tbl_mittal * ERROR at line 1: ORA-14400: inserted partition key does not map to any partition
AS tbl_mittal is having hugh number of records so I am providing only few rows from tbl_mittal table as test data.
For the above data set i need to divide into 5 partittions and need to updated the partitonid with the partition number for each partition set,like the below result set
As per Article mentioned in Oracle Base,I have converted non-partitioned table (1 million data) into range-partition table,but,I don't see performance improvement in explain .
