Table Partitioning - Range On Datatype Number (21, 7) And Varchar2
Nov 15, 2013
Database Version : DB : Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit ProductionOS : HP-UX nduhi18 B.11.31 U ia64 1022072414 unlimited-user licenseAPP : SAP - ERP I have to RANGE partition on UPDATED_ON or PROFILE either one table which is having below
structure : Name Null? Type
-------------------- -------- --------------------------------
MANDT NOT NULL VARCHAR2(9) MR_ID NOT NULL VARCHAR2(60) PROFILE NOT NULL VARCHAR2(54) REGISTER_ID NOT NULL VARCHAR2(30) INTERVAL_DATE NOT NULL VARCHAR2(24) AGGR_CONSUMPTION NOT NULL NUMBER(21,6) MDM_VERS_NO NOT NULL VARCHAR2(9) MDP_UPDATE_DATE NOT NULL VARCHAR2(24) MDP_UPDATE_TIME NOT NULL VARCHAR2(18) NMI_CONFIG NOT NULL VARCHAR2(120) NMI_CONFIG_FLAG NOT NULL VARCHAR2(3) MDM_DATA_STRM_ID NOT NULL VARCHAR2(6) NSRD NOT NULL VARCHAR2
[Code]....
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
I am facing issue related to Number data while it is being converted to Varchar2, it is automatically getting rounded off after 32 decimal place.My database version is "Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production".
"First" string got rounded off to 97 (last 2 digits) instead of 9679 but for "Second" record it holds the actual value.Only thing which I could figure out while the number is getting type casted to String, it is getting rounded off to 32 decimal place.throw off some light on it and provide the solution how the original record can be kept intact without rounding off.
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.
I have a stored proc which takes IN parameter of datatype varchar2.When I am trying to run the proc it is throwing error that "input buffer too small".The datatype assigned to IN parameter is of varchar2(200) but actually the length of the parameter passed is around 500 characters.the way to increase the length of Input parameter to 500 characters??
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')) (partition p0 values less than (20120101))
I'm facing a problem where I create a form and I want to feed time in "HH:MI" format, Firstly I choose the "Date" datatype, but during the feeding of time i.e "00:30", means if I want to feed only mints, then it doesn't accept, at the other hand if I feed "01:30" means mints with hr then it accepts.
To get rid of this problem I changed datatype "Date" to "Varchar2".
I create 3 columns on my form "TTL_WORKING_TIME" - "TTL_RUN_TIME" = "BRK_DWN_TIME". If I get any value in "BRK_DWN_TIME" column thn it has to be distribute in 3 or 4 reason of B/D, means if I get 00:30 mints brkdwn thn 00:15 mints for "reason1" and 00:15 mints for "reason2".
How I make calculation where I use "Varchar2" datatype.
I have to change the datatype of a column from CLOB to varchar2, without changing the order of the columns. The table has no data. I could find any other way other than dropping the CLOB columns and then adding new columns with varchar2 datatype. But this changes the order of the columns in the table.
here is the situation, I have to write a function that receive as parameter a datatype varchar2 and validate if the letter is less than "A" or greater than "Z", it must print do not correct, or correct depending on the situation, no problem so far, the only problem I've got is: If the symbol is ";" is valid, but i do not know how to write it, It does not depend on the PL/SQl languaje but depends on the logic itself.
DECLARE v_nombre varchar2(20):='john;%'; vv varchar2(1); begin for i in 1..length(v_nombre) loop
I am trying to load the data from .csv file into the table using SQL Loader.
The table has the following schema: src_id : number, dest_id : number, range: intsys.interval_typ --- > a type containing (lower,upper) payload : varchar2(100)
The loader.ctl file is :
load data infile * append into table sb_packet fields terminated by "," optionally enclosed by ' " ' (src_id,dest_id,range,payload) BEGINDATA 3,32,intsys.interval_typ(10043,142703),"misc data"
When I use the following this ctl file to transfer the data, i get the following error:
SQL*Loader-418: Bad datafile datatype for column RANGE
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?
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')));

I have 2 tables.The column in table A is number and Column in table B is a varchar2 datatype.I have to use the Column of table B as a filter to column of Table A.Below is the example.
create table A(Col1 number); Inert into A values(1); Inert into A values(2); Inert into A values(3); Inert into A values(4);
Create table B(Col1 Varchar2(100)); Insert into b value ('1,2,3');
Select * from A where col1 in (select col1 from b) Error: Invalid Number
Is there a way to convert the varchar to number.The varchar field have multiple characters (numbers) seperated by commas.
When I try to convert numeric values � number(19) p.s 111111111111111111, the to_char function returns �1111111111111110000� because the to_char functions doesn�t support precision bigger than 15.
I have table customer which contains a column CUSTOMER_FIRST_NAME
CUSTOMER_FIRST_NAME VARCHAR2(50)
What will be sql statement to add a constraint on the CUSTOMER_FIRST_NAME column of the CUSTOMERS table so that the value inserted in the column does not have numbers ?
I need to create a composite unique index on varchar2, number and CLOB column. I haven't used such index before that have the CLOB column indexing. I found the below link related to CLOB indexing...
[URL]......
Links from where I can get related info. Also I would like to know the impact of such index on performance. I have to store and process around 50 million records in such a way, will it be beneficial to use this index?
In my table there is column with number datatype of size col1 number(15,3) and my data in column is like
001 002 003
and i am changing its size to number(10,3) by alter table command but it not allowing. why?????? as my data in that column still satisfy the the changes.
and even when i modify the char column to varchar2 column by alter table command and changing the size of that column,it is not allowing me to change it why?
I want to decrease the size of testid column of number datatype in my "test" named table from size 20 to 15 and the data of maximum size is of 10 digits. but oracle throws an error "ORA-01440: column to be modified must be empty to decrease precision or scale". i cant understand why it is happening?
what is the reason behind it even though new size is maximum than the maximum size of existing data. but when i decrease the size of "varchar2" then oracle does not through any error.
We have truncated number based on the decimal value. i tried to truncate number based on the precision using cast function. i got an error "value larger than specified precision allowed for this colum".
create table TEST_NUMBER (id number(4,1)); insert into TEST_NUMBER values(1234.789888888888);
[code]...
ORA-01438: value larger than specified precision allowed for this column 01438. 00000 - "value larger than specified precision allowed for this column" *Cause: When inserting or updating records, a numeric value was entered that exceeded the precision defined for the column. *Action: Enter a value that complies with the numeric column's precision, or use the MODIFY option with the ALTER TABLE command to expand the precision.
I have a Number(18,0) datatype.It could have millions/billions stored in that field.How can I show that amount in the form of $7,123,787 ($ sign and commas)?
By using To_char function like below, I am not getting the desired format.
Select to_char(123000000.25, '$9,9999999999.00') FROM dual;
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.
