i have a requirement To partition a Table byRange partition with a Number column. but the issue is the range Must be in a Date datatype ,
For example
partition by range (date_key)
( PARTITION DEF VALUES LESS THAN ('01-SEP-10'))
the date_key column has values of date in number format. like "20101014"

As per my knowledge, RANGE is better suited for DATE or NUMBER. and INTERVAL partition is possible on DATE or NUMBEr . Column PROFILEIts is of VARCHAR2 datatype. I know still I can partition as Oracle internally convert varchar2 to number while inserting data. But INTERVAL is not possible. How to RANGE partition on PROFILE ? Column CREATED_ON :It is of NUMBER with decimal
11gr2, We need to do partition a existing table of size 20g, But partition key column is NUMBER type and data stored in unix date format.I would like to create a monthly partition table as below. But not able to create.
create table student ( ENTRY_ID number(5,1), NAME varchar2(30 BYTE) ) partition by range ( fun_unix_to_date (ENTRY_ID) ) --> fun_unix_to_date is a customized function to convert unix time stamp to date format.
INTERVAL (100) ( PARTITION CATCH_ALL values LESS THAN (to_date('01-MAR-12','DD-MON-YY')));
ERROR at line 5:ORA-00907: missing right parenthesis
Other than the obvious to me, where interval partitioning creates partitions as needed. Is there any performance benefit from using interval partitions vs date range partitions.
One draw back for me is that developers do access the partition name in some of their queries, so if I use date range partitioning this will not break their code. I could not find a way to assign a name to a partition when using intervals, is this always system generated or can this be over-ridden.
I am running Oracle 11.1.0.7 soon to be running on 11.2.0.0
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'))

I have a database 10.2.0.4 running on 64bit Solaris 5.10 SPARC.
Question:
CREATE TABLE SYSTEM.BIG_TABLE1
(
ID NUMBER(10),
LOOKUP_ID NUMBER(10),
DATA VARCHAR2(50 BYTE)
)
[code].......
When I query dba_tab_partitions. I get this result
select table_name, partition_name, high_value, high_value_length from dba_tab_partitions where table_name = 'BIG_TABLE1' ;
table_name partition_name high_value HIGH_VALUE_LENGTH
------------- -------------- ---------- -----------------
BIG_TABLE1 BIG_TABLE_2003 1000000000 10
BIG_TABLE1 BIG_TABLE_2004 5000000000 10
BIG_TABLE1 BIG_TABLE_2005 MAXVALUE 8
3 rows selected.
Now my question is why do I see max_value_lengh=8 when my column value is 10. I don't get any error. But I do like to understand it.
At moment we use range-hash partitioning of a large dimension table (dimension model warehouse) table with 2 levels - range partitioned on columns only available at bottom level of hierarchy - date and issue_id.
Result is a partition with null value - assume would get a null partition in large fact table if was partitioned with reference to the large dimension.Large fact table similarly partitioned date range-hash local bitmap indexes
Suggested to use would get automatic partition-wise joins if used reference partitioningWould have thought would get that with range-hash on both dimension.
Our organization is attempting to learn more about the partitioning features of Oracle 11g. I've been reading the partitioning manuals, and I have not found a clear answer on this topic, but I suspect I know the answer.
If you create a range partitioned table; using interval partitioning, say something like this:
CREATE table range_parti (
CODE NUMBER(5),
DESCRIPTION VARCHAR2(50),
CREATED_DATE DATE)
PARTITION BY RANGE (created_date)
INTERVAL (NUMTOYMINTERVAL(1,'MONTH'))
(
PARTITION my_parti VALUES LESS THAN (TO_DATE('01-NOV-2007','DD-MON-YYYY'))
);
but you try to insert a null value as the partition key, you get the following error:
SQL> INSERT INTO range_parti VALUES (1,'one',NULL);
INSERT INTO range_parti VALUES (1,'one',NULL)
*
ERROR at line 1:
ORA-14400: inserted partition key does not map to any partition
Elapsed: 00:00:00.07
Is there no way to tell it to use a default partition for NULL values? Or specifically designate a partition for NULL values WITHOUT having to manually list out each partition? It seems it works if you don't use the INTERVAL keyword, list out your partitions, and use MAXVALUE. However, our hope to avoid having that as it creates monstrously huge DDL statements for tables that have lots of date ranges, and we will be forced to manually add new partitions each month as data is added/time passes.
It appears from my experience so far, if your column can allow nulls, you cannot use interval range partitioning on that column.
I have a table with two columns Column1 and column2
Like such
create table testTable (column1 number(15), column2 number(15));
insert into testTable values (1,5);I need to find the numbers between column 1 and column 2 including the column 1's number and column's 2 number.
so my answer set should be
1,2,3,4,5
I have following requirement. Let say i have to generate a range based on "start number" and "end number" dynamically.Some kind of hash buckets.
e.g Start Number : 1 and End Number : 1001.
Also i want to divide that range based on some dynamic value like for above example 10 ranges of 100 each. and both 1 and 1001 should be included only once and the next row start number cannot be same as previous row end number.
Means
Range 1 1 -101
Range 2 102-200
Range 3 201-300
...
Range 10 901-1001
Is there any way of doing it automatically. I tried with Model clause. it works fine for even cases but for odd i have issues also when i take small start and end number i get an error.
SELECT case when ranges=1 then ranges else ranges+1 end Start_Id, ranges+round((1001-1)/10) End_Id
from
(
[Code].....
I want this to be generic for any values here 1 is Start Number 1001 is end number and 10 is the bucket. I need these parameters dynamic and want's the same kind of results for any values.
I have a query that seems to repeatedly call an index scan on a table for reasons I'm not sure about. Why it would be doing the index scan on totaldwellingarea in the dimensions table (DIMEN_PID_TDWELLAREA) repeatedly?

I have a table which has 2 range partitions on a date column currently.
CREATE TABLE TABLEA (
RUN_TIME INT NOT NULL
)
PARTITION BY RANGE (RUN_TIME)
(
PARTITION DATAONE VALUES LESS THAN (20110101000000) TABLESPACE SPACE1
PARTITION DATATWO VALUES LESS THAN (MAXVALUE) TABLESPACE SPACE2
);
I am planning to drop one partition i.e DATAONE. So table will have one partition left for MAXVALUE. Does it make sense to have a partition with MAXVALUE? Isn't it same as TABLEA in terms of number of records? TABLEA is also in tablespace SPACE2. Should i remove partition DATATWO also? If i have to what is the best way to move all DATATWO records to base table TABLEA?

We are using Oracle 11g with Apex 3.2 on AIX. We are reporting data from customer satisfaction surveys. I'm using the following sql to create my report
<code>select * from(
select month,'Overall Satisfaction' as q_group, 1 as srt,Overall Satisfaction,site,
case when count(*) < 31 then '*' else
round((sum(ttos)/count(*))*100,0)||'/'|round((sum(bfos)/count(*))*100,0)||'/'||count(*) end ospct
from v_XXX_report a,(select distinct month_dt month from v_XXX_report) b
where Overall_Satisfaction is not null and year_dt = 2012
[Code]....
The problem is that site is not allways present and sometimes I have other variables in addition to site. This creates a situation where the month columns will not allways appear at the same column number. For example, When I run this query as is then the "JAN" column is Col3 (first column is a break, col2 is not shown). When I run this query without site then "JAN" is the second column. I would like to create column links for the "JAN" - "DEC" columns but not for any other columns.
Another issue - in the column link creation screen I can create up to 3 variables that I can pass to the next page. Since my query is a pivot I'm uncertain how to pass the column heading or the row value (for col2)
ie
Overall Satisfaction JAN FEB MAR APR MAY ...
Overall Satisfaction 12/12/200 12/12/210 12/12/220 12/12/230 12/12/240...
Recommend 12/12/200 12/12/210 12/12/220 12/12/230 12/12/240...
etc.
So if I clicked on the values at Recommend:FEB how can I get "Recommend" and "FEB" into variables that I can use on the next page? I've tried #column_name#, #month#, #q_name# and #APEX_APPLICATION.G_F10# but no luck.
I have problem to transfer data in non partitioning table to partitioning table.
I have non partitioning table and i create new table partitioning that have same column and type like in non partitioning. So how can i transfer data from table in non partitioning to table in partitioning?
I have a table where i have description column which free text column, the data in description column is seperated and i want to corvert 1 row data in multiple rows dependeing on the number of words.
eg
id description
78664 Pumps Alarm from CAMS RTU154
In the above example this column has 5 word so i want data in 5 rows like below
78664 Pumps
78664 Alarm
78664 from
78664 CAMS
78664 RTU154
This column data can be varied from 1 to any number of words.
is there some performance/access difference between a bitmap index on a number column and char(1) column? Both columns are not null with a default value.My application has a querie like this:
select ass.column20, ass.column30from table_a pucinner join table_b asson ass.column1 = puc.column1where pc.column_char = 'S'and ass.column_char02 = 'P'
If I create a bitmap index on column "column_char", the access plan is not changed. But changing the column datatype to number(1) and obviously the values, the index is accessed and the cost decreases.This table has 4.000.000 rows. Oracle 11.2.0.2SO

alter table n546830.mth modify (DAY_DK date);
Next I tried making my temporary table "mth" a date column. When I an the exchange partition command I get the following error:

Method I can use to convert a number(10) to date column and keep the information in a table. Note, I don't care about HH:MM:SS as I never had that information to begin with and would be happy to set that part of the date column to all zeroes "00:00:00"

How do I perform it?
I have a query that should return count the number of rows depending on the value of SLOT. The expected result will be like this:
WIPDATAVALUE SLOT N M
1-2 TRALTEST43S1 1 3
1-2 TRALTEST43S1 2 3
3 TRALTEST43S1 3 3
4-6 TRALTEST43S2 1 4
4-6 TRALTEST43S2 2 4
4-6 TRALTEST43S2 3 4
7 TRALTEST43S2 4 4
The M column is used to count the total number of occurrences of a SLOT. Now, as for the N field, this is used to count the occurrence of the SLOT. In my example for the SLOT TRALTEST43S1, it has three occurrences so M will be 3. Why 3, is because of the WIPDATAVALUE. The WIPDATAVALUE of TRALTEST43S1 is 1-2 and 3. 1-2 WIPDATAVALUE signifies two occurrences (one to two) and 3 signifies only one occurrence. As for N, it should just count the number of occurrence. To further explain, see below:
WIPDATAVALUE SLOT N M
1-2 TRALTEST43S1 1 3 -> First occurrence in the total of 3
1-2 TRALTEST43S1 2 3 -> Second occurrence in the total of 3
3 TRALTEST43S1 3 3 -> Third occurrence in the total of 3
4-6 TRALTEST43S2 1 4 -> First occurrence in the total of 4
4-6 TRALTEST43S2 2 4 -> Second occurrence in the total of 4
4-6 TRALTEST43S2 3 4 -> Third occurrence in the total of 4
7 TRALTEST43S12 4 4 -> Fourth occurrence in the total of 4
This is the query that I have so far:
SELECT DISTINCT
WIPDATAVALUE, SLOT
, LEVEL AS n
, m
FROM
(
SELECT
WIPDATAVALUE
, SLOT
, (dulo - una) + 1 AS m
[code]....
I think that my current query is basing its M and N results on WIPDATAVALUE and not the SLOT that is why I get the wrong output. I have also tried to use the WITH Statement and it works well but unfortunately, our system cant accept subquery factoring.
