Partitioned Table Based On Field
Nov 27, 2012
I have partitioned the table based on field.But when I am selecting by Partition or by the field I am getting Explain plan as Table Access full.I am pasting the sql and Explain Plan here. The table has two partition by BOOKING_DT_WID. One less than 20100801 and other less than 99991231.
CODESELECT * FROM WC_BOOKING_SALESREP_F WHERE BOOKING_DT_WID >= 20100801;
SELECT * FROM WC_BOOKING_SALESREP_F PARTITION(SALESREP_LESS1_99991231);
Here is the Explain Plan for the same.
CODESELECT STATEMENT ALL_ROWSCost: 1,501 Bytes: 293,923,641 Cardinality: 809,707
4 PX COORDINATOR
[code]....
How do I know if the sql is doing partition prune.

I have a table where i need to update one field values based on another field of the same table , simply as it is.I have done this using one select all check box , on clicking that all check boxes of item_trans table will get selected , then i will un select some of check box and then using one button, i will update the value of the fields which are checked only.
I have put the sample code but when i am updating its taking long time and hanging.I am also attaching the form based on the test case provided.
--tables with insert statement
create table item_trans (trans_item varchar2(12),trans_qty number,trans_act_qty number)
insert into item_trans(TRANS_ITEM,TRANS_QTY,TRANS_ACT_QTY) VALUES ('TREE1',40,NULL);
insert into item_trans(TRANS_ITEM,TRANS_QTY,TRANS_ACT_QTY) VALUES ('TREE2',20,NULL);
insert into item_trans(TRANS_ITEM,TRANS_QTY,TRANS_ACT_QTY) VALUES ('TREE3',20,NULL);
--i want to set the value of trans_Act_qty as trans_qty
--i create one dummy or test block to keep the select all check box. for that table test script is
CREATE TABLE TEST
(
C VARCHAR2(2000 BYTE),
B NUMBER,
A NUMBER
);
insert into test (C,B,A) values ('A',1,1);
--code written in select all check box which is created on test.block.
BEGIN
GO_BLOCK('item_trans');
FIRST_RECORD;
LOOP
:M_END_YN := :M_END_ALL;
[code].......
--code written in M_END_YN ( actual check boxes where i will uncheck).
IF :M_END_YN = 'N' THEN
:M_END_ALL := 'N';
END IF;
--code written on button to update those values which are checked.
BEGIN
GO_BLOCK('item_trans');
FIRST_RECORD;
LOOP
IF :M_END_YN = 'Y' THEN
[code]......

I want to display Week No as the heading.So, I have these:
define week_no=number
column week_col new_value week_no
select to_number(to_char(sysdate, 'ww')) week_col from dual;
I have tested it and it is working as the way I expected: select 'to display week no as column' "Week &week_no" from dual;
The output:
Week 16
----------------------------
to display week no as column ...So how do I display Week 15, Week 17 etc based on the calculation of &week_no e.g. &week_no+1?

In the query below, I'm attempting to replace task codes with task descriptions by left joining to a multi-purpose control table.
In our corp, the description for the task code varies based on the value of change_program in each record, so rather than referencing the value of code_index.tabl statically as I do in the query below (201), I need a dyanamic variable to be defined for each record based on the value of work.change_program, which would represent the value for code_index.tabl.
For each record
if change_program =1 then v_tabl = 201
elseif change_program =2 then v_tabl = 202
elseif change_program =3 then v_tabl = 203
else v_tabl = 201
how to declare and use variables.
SELECT account,
change_program,
task_code_01,
task_code_02,
task1.longdesc,
task2.longdesc
FROM work

I was about to move some tables from one table space to another but it seems it is not possible to move partitioned tables between table spaces of different block sizes.
So far the only option I have is to export and then import back the data.
know if there is any way to move a partitioned table between table spaces of different block size?

I have a list sample:
Order#Location VendorName
--------- --------- ------- -------
145646842 MLIQUID02T 368308 JOHNNEISHA
134962284 MLIQUID02T 368308 JERRY
141138899 MLIQUID02T 368308 CARLENA
5078916 MLIQUID02T 368308 DONNA
[code]....
What I'd like to do is run SQL that can create output where I get 2 records from each Location. Example:
Order#Location VendorName
--------- --------- ------- -------
145646842 MLIQUID02T 368308 JOHNNEISHA
134962284 MLIQUID02T 368308 JERRY
13999694 MLIQUID03T 368308 TINA
175439805 MLIQUID03T 368308 RANDI
4801973 MLIQUID05T 368308 DIANA
55907648 MLIQUID05T 368308 DESIREE
Personally, I don't need the top value(s), but it would be nice.I was trying a few routes with rownum, and I can get it to pull 1 set of pairs with a where location= condition, but I can't seem to successfully combine the two.

I have a need to change the LOV of a page item's select list based on the selection in another page item's select list. So in other words, for a page item that is a select list, I need to use one LOV normally, and a different LOV if the value of a different page item is set to X.
A dynamic action would be useful here (on change where Select List 1 = x), but I don't know how to take the action of changing LOVsfor Select List 2 based on that action.

I have a table like this:
CREATE TABLE CARGA_P_RECARGA_NEW1
(
TELE_NUM VARCHAR2(10) NOT NULL,
FECHA DATE NOT NULL,
[Code].....
Then I tried to insert some rows in that table, every insert statement is like this:
INSERT INTO CARGA_P_RECARGA_NEW1
VALUES
('3134769595','20/01/2013 07:22:50','1107','CONFB_20121121_20121122175002 60000000000000000090.TXT',0,16,'8327--7991284',1);
Every insert I executed had the month 01 because I expected to query results only from partittion p_0113 but nevermind how query I execute, the result is always the same. I mean if I excute this statement:
SELECT * FROM CARGA_P_RECARGA_NEW1 P_0113;
I get the same result when I execute any other like this:
SELECT * FROM CARGA_P_RECARGA_NEW1 P_0213
What is the error here ?

We have a partitioned transaction table in our Datawarehouse environment which has the following partition strategy
SCHEME=DATE-HASH
GRAIN=DAILY
SUBGRAIN=NONE
HASH=8
FROM=31/12/2011
We recently had to delete data from the table. This was a simple delete statement with a where clause and without taking into consideration any partition/subpartition clauses. Post committing the delete we have a count mismatch problem with two queries in particular
select count(0) count_without_parallel FROM TRANSACTION_TABLE t;
--THIS RETRIEVES *15774811* ROWS
select /* parallel(t,default) */count(0) count_with_parallel FROM TRANSACTION_TABLE t+
--THIS RETRIEVES *15777617* ROWS WHICH IS THE ACTUAL EXPECTED COUNT.
I also ran the following just to summarize
select (select count_with_parallel from (
select /* parallel(t,default) */count(0) count_with_parallel FROM TRANSACTION_TABLE t))+
-
+(select count_without_parallel from (+
select count(0) count_without_parallel FROM TRANSACTION_TABLE t)) as false_difference
from dual;
The difference in *2806* rows as expected.To re-affirm my counts I ran
select /*+ parallel(t,default) */
'count_on_t',count(*) from TRANSACTION_TABLE t
group by 'count_on_t'
order by 1;
--THIS RETRIEVES *15777617* ROWS
Removing the parallel hint reverts back to the lesser count. Not sure what is wrong but something prevents the query from parsing the whole table and/or partitions and subpartitions.

A question regarding analyzing behavior of partition table on Oracle -
Is analyzing different sub partitions within a partition is same as analyzing that partition and what about vice-versa?

I created table that is range partitioned:
CODEPARTITION t1p1 VALUES LESS THAN (TO_DATE('2011-11-01', 'YYYY-MM-DD'))
PARTITION t1p2 VALUES LESS THAN (TO_DATE('2011-11-02', 'YYYY-MM-DD'))
....
PARTITION t1p4 VALUES LESS THAN (MAXVALUE)
Every year partitions will be added for next 12 month. The table partition will be dropped every month (I have to have data from last six month so in July I could drop partition t1p1, in August - t1p2....). How many tablespaces should I create for this table and how place partitions in them to have data for last six month and use minimum space on disk?
I was thinking about one tablespace for whole table because space of each dropped partition will be reused, what do you think about that?

I have a partitioned table that is streamed to another database. I need to archive data on that table. That is I need to add a partition and remove a partition.
If I make those changes to the source table, will it stream over to the destination table?
If not, can I ...
pause streaming make changes to source table make same changes to destination table sreenable streaming. I know making data changes to the destination table can screw up streams but not sure if that holds for ddl.

I have a partitioned table (one partition per month). Every month there are added about 1GB data. What extent size should I set? 1GB will be ok?
What if data will be greater than 1GB, adding new 1GB extent takes probably a lot of time and clients may see delays while they're inserting in this time? (it's OLTP system)
When new extent is allocated? Exact in time of lacking space in existing extent or before? Partitions are dropped after one year so free space isn't a problem.

Facts:
Oracle 10.1.0.5
AIX 5.3
My table, HMTX have 10 partitions each of one have 6 millions of rows (average). We have 7 partitioned LOCAL indexes in that table.
Every month we load data into a new partition (6 million of rows aprox) and drop the oldest partition in table HMTX.
In order to do that we have a script that contain the next statements:
drop of all indexes
drop index n1;
drop index n...;
drop index n7;
[Code]...
create indexes again with tha same storage and degree parameters
CREATE INDEX hmtx_TST_N1 ON hmtx (campo1, campo2, campo3 .... campo8)
TABLESPACE xxxx
PCTFREE 0
INITRANS 2
[Code]....
My problem is in rhe index creation section, despite use parallel with degree 8 and nologging the index was created in :
Elapsed: 02:43:50.85.
In past months that index was created in :
Elapsed: 01:43:36.94
Elapsed: 04:48:31.24
Elapsed: 00:57:16.28
there are another way in order speed the index creation ?? o another way to disable ths index ??

I have table with 4 partition by range partition. I am loading the table in bulk mode to latest partition. Before I load , I dropped the index and after Load I will be creating index. So when I am dropping index, it is dropping index from all the partitions and when creating the index, I am creating the index for all partitions. When I am creating index using local, it is telling you have to create local index for all partitions at the same time. because of that I have to drop and recreate all indexes again. Again I have to gather stats for whole table .
I was thinking we can build index for one partition and index should remain as is for old partitions If this is not the case, how do I plan my load for a partitioned table using bulk mode to latest partition.

I have normal tables with hugh Data and would like to increase the performace by following means:
1) Add a new column in each table. Say this column Name is IS_LIVE. This new column have only two value 1 ( LIVE ) OR 0 ( NOT LIVE ).
2) Change the normal tables to Partitioned table. There would be only two partitioned in all the table. The partitioned key column would be IS_LIVE and both partitioend recrods would be in two different tablespace.
3) Added a POLICY function to these partitioned table to Always add a Query Predicate of '1' to all queuries.
I am interested to know that what kind of Indexes ( Global Or local ) would be suitable for these kind of Design.Is there any use of having Local index on IS_LIVE.Please note that Primary Key doesnot have this new column in it.
