<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 RepliesI 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 ?
I have question related to LONG datatype. Actually from google and get to know that one table can have only one LONG datatype when i searched for reason . i got these resons:-
With 9i (I believe) and later versions, Oracle deprecates using the long datatype in favor of the lob (clob, nclob and blog) datatypes. It is only supported for backward compatibility.
Restriction:- It can not be used in create type as an attribute of the defined type.
It can not be used in where conditions.
There can be no indexes on long columns.
Regular Expression are not possible.
long can not be returned from a stored function.
SQL can not call functions that have an attribute of type long.
And even more restrictions.
So I want to know that is only reason because of that Oracle doesn't allow us to make two Column or is there any strong reason which make it more logical Like storing of data in Row blocks or some thing else.
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 Relatedi 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 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.

Action: Correct the maximum line size to be in the range [1, 32767]."

I have a table called Student and a column as name now if i write a Query

I have one query regarding how to retrieve the CLOB data.
The requirement is something that in the select statement there are around 20+ columns which i need to retrieve from around 5 tables after joining.
Since the result set after joining also will get duplicate values i need to use distinct keyword to filter the resultset. But in the 20+ columns there are 2 CLOB data columns which i need to retrieve.
Whenever i use DISTINCT i'm getting ORA-00932: inconsistent datatypes: expected - got CLOB error. I know that DISTINCT keyword cannot be used for CLOB datatypes.
I have a two question.
Question 1:How to select all columns from table except those columns which i type in query
Question 2:How to select all columns from table where all columns are not null without type each column name which is in empty data

I'm trying to create a table 'a' with column name as 'flag' and datatype as 'boolean' ie. create table a(flag boolean);
is it possible in sql or pl/sql in oracle?
If its possible to create a table and also let me now inserting row and what boolean should return.
a) What if i want to find out the Datatype of a specific column in the Table.
b) How do i find the Column Datatypes?
Below is my requirement.
Need to change the precision of a column in a existing table. Statistics about the table
* has over 130 columns
* More than 300 million records
* Column to modify is #121 which has data
* No primary key defined
Since the column has data, it is not possible to modify with a simple Alter.
Second option - create temp column in same table, update from original, put null in original, alter, update back from temp, drop the temp column. This approach is very expensive and time consuming.
Also the Column ID needs to preserved as #121.

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 ?
