SQL & PL/SQL :: Decrease Size Of Number Datatype Column
May 24, 2012
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.

The below table and functions are examples, but issue is like this.
i have one issue while forming below sql , Application will form this query at run time wih required inputs
it is failing because the application will not support the clob datatype.
Table : T_E (similar to EMP table structure)
This table has data similar to emp but bulk data around 10k records.
Query formed
select empno,ename, get_employees(deptno)
from t_e;
This sql query this is failing when function return varchar2 string more than 4000 size.Because in sql query size should not exceed 4000 for varchar2 data type , function return size can be upto 20000
Function which
CREATE OR REPLACE FUNCTION get_employees (p_deptno in emp.deptno%TYPE)
RETURN varchar2
IS
l_text varchar2(32767) := NULL;
BEGIN
FOR cur_rec IN (SELECT ename FROM t_e WHERE deptno = p_deptno) LOOP
l_text := l_text || ',' || cur_rec.ename;
END LOOP;
RETURN LTRIM(l_text, ',');
END;
I can try this with clob but application doesn't support that..so i tried with using clob in above function , after that while returning to application i want to conver the clob to char and return the entire string
select empno,ename, to_char(substring(get_employees(deptno),1,4000)) -- first 4000 characters
, to_char(substring(get_employees(deptno),4000,8000)) -- next 4000 characters
from t_e;
But this is failing how to return the entire string in above sql

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 want result like 1.8

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;
Result is (no commas):
$123000000.25

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".
1) create table test18 ( col1 varchar2(10), val Number);
create table succeeded.
2) insert into test18 values ('First', -347026.6408499652467480885711448714129679); -- After decimal 34 digits
1 rows inserted
insert into test18 values ('Second', -347026.64084996524674808857114487141296); -- After decimal 32 digits
1 rows inserted
3) select * from test18;
COL1 VAL
---------- ----------------------
First -347026.6408499652467480885711448714129679
Second -347026.64084996524674808857114487141296
4) As per the requirement, all the columns would need to be concatenated as a single string along with comma delimiter
select col1 || ',' || val as record_string
from test18;
RECORD_STRING
---------------------------------------------------
First,-347026.64084996524674808857114487141297
Second,-347026.64084996524674808857114487141296
"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.
Expected Output_
RECORD_STRING
---------------------------------------------------
First,-347026.6408499652467480885711448714129679
Second,-347026.64084996524674808857114487141296

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

on this query. I need to get a particular value from a column which is a BLOB datatype. Here is the sample
data ID TESTDATA1 Best Buy
00001234 12222 30 00 2
Lowes 00001234 12222 100 00 3
Walmart 00001234 12222 129 00 4
abc 00001234 12222 5000 00 5
Toshiba 00001234 12222 21 00 6
abcdefghij 00001234 12222 49 00
Where '00001234' is the Invoice , '12222' is Netamount field and highlighted in red is the $ amount for that invoice.
The only data i need query to return 12222 (netamount)= $amount. I tried using substr select substr((TESTDATA),19,26)test from TABLEA; But this gives me the only the first row but not other amount which have different positions.
Here is the desired output
OutputID TESTDATA 1
12222 30 2 12222 100 3
12222 129 4 12222 5000 5
12222 21 6 12222 49

in this query pdate has timestamp datatype and in shift sample ppdate column has date type. so i am not able to insert value from process daily data table.
getting this error.

I have a table defined where some columns are of the datatype RAW(16). In fact these are foreign keys to other tables. Our company has a policy that all primary keys are of the datatype RAW(16). Not much I can do about that.
Now I want to retrieve all columns of a certain row in that table and just visualize the foreign keys in hex format. All values are filled out nicely, except the columns with datatype RAW(16). Is there something special I have to do to retreive and display these? I defined an item as text-field for these, but this doesn't seem to be working...
I'm using APEX 4.1.1.00.23 at this moment...

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.

I have a table that has column with BLOB datatype. I am trying read only the inputted String from the BLOB datatype column. I have used the below query,
SELECT utl_raw.cast_to_varchar2(column1) FROM TAB1
and it gives the result as
<H2><FONT color=#cc0000><EM><U>test</U></EM></FONT></H2>
However I would like to extract only the string "test" which is inputted. Is there any build-in function in oracle which will satisfy this requirement?

payload : varchar2(100)
The loader.ctl file is :

I need to modify the column type that already has data in it, i need it change varchar to number then The datas entered have $ and , (e.g $3,200). I need the $ and , removed with column type set to numbers.
When i currently do this i get the following error:
The TABLE operation was not successful for the following reason:
ORA-01439: column to be modified must be empty to change datatype
I've tried unloading the data and loading the data using the spreadsheet, cut and past and csv file but both give me more errors, so i just want that one column modified.
