i am trying to calculate the avg size of a row, in which i have one column which has clob datatype,
for rest of the datatypes i am using (avg(vsize(col_name,varchar2(10)))), i want a simple function that can calculate the clob datatype.
I would need to convert the column datatype from BLOB to CLOB. currently in the table, the BLOB column has the data. the requirement is to convert this column from BLOB to CLOB datatype.
How to convert from BLOB datatype to CLOB datatype ?
how can i update CLOB values in Oracle? I am passing string values to Clob datatype from .Net Eg '13223311','12122112','122125552'
View 6 Replies View Related<ORACLE VERSION : 11.2.0.2.0> i have created a table with CLOB as datatype for one of the columns, I am trying to store a string ( I am not sure about the length of the string) , when i am querying on my table for the CLOB column,instead of the actual string "(HUGECLOB)" is coming. How to get the actual string in case the problem is with the SIZE.
View 1 Replies View RelatedI 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.
How could we concat a clob with a char datatype.
declare
a clob;
b varchar2;
c clob;
begin
c:=a||b;
end;
When execute above code in form runtime, I get error ora-32767.
"ORA-29287: invalid maximum line size Cause: An invalid maximum line size value was specified.
Action: Correct the maximum line size to be in the range [1, 32767]."
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
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.
when trying to calculate the occupied space for a table, I'm using DBA_SEGMENTS, which works fine as long as the table does not have a BLOB column.
As far as I can tell, the size of the BLOB data is stored with the SEGMENT_TYPE = 'LOBSEGMENT', but I cannot find a view that tells me which DBA_SEGMENT row belongs to the BLOB column in the table I'm checking.
To give you an example:
select sum(BYTES)
from DBA_SEGMENTS
where owner = user
and segment_name = 'MY_TABLE'
group by SEGMENT_NAME
returns 262144
running:
SELECT sum(length(blob_column))
FROM my_table
returns 821333
There are entries in DBA_SEGMENTS for my user with the type LOBSEGMENT, but I cannot find a way to map the correct DBA_SEGMENTS row to the table I am checking.
I'm using Oracle 10.2.0.3.0 on Redhat

We have 2 tables.
Example :

I what create new table/view which contains all value of both table and new column called Total Amount.
