I would like to know if there is possible to transform a CLOB type variable intro a long type variable. I know, that LONG is obsolete in Oracle, but I need it, because in a PL/SQL 'execute immediate' sentence a CLOB is not allowed.
I am more of a C/C++ guy and relatively amateur in oracle. I have to update a table field from "Long" to "CLOB". I have planned to do a simple alter table, and as far as I know there won't be any issues.
Queries: 1. Although I have triple checked, is there any scenario under which there can be any data loss during the data type change? The data is very critical and no data loss can be entertained. 2. Is there any easy way to update all the related views without having to do so manually? 3. Any particular precautions I should take before introducing the change?
We have a huge table in production, with LONG column. We are trying to change its datatype to CLOB. The table has 120 Million records and is of 270 GB in size.
We tried using the oracle expdp/impdp option to try the conversion in our perf environment. With 32 parallels, the export completed in 1.5 hrs. However, the import took 13 hrs.
I also tried the to_lob option using inserts, it went on for 20 hrs and I killed the process. Are there any ways to improve the performance of LONG to CLOB conversion on huge tables?
display or get values stored in a long column.i tried the below code, but myvar is shown as null. am i missing something here or is there a better apporoach than this ?. There are actually 16 rows returned for this query but with empty values for 'high_value' column which is critical for me. How can i do this long to varchar convertion ?
SET SERVEROUTPUT ON DECLARE my_var long; BEGIN for x in ( SELECT high_value FROM all_tab_partitions WHERE table_name = 'SALES_DISCOUNT' AND table_owner = 'CED12' ORDER BY partition_position DESC ) [code]....
But now I need to convert all my CLOB data into UTF-8 charset for external requirements and stored this new CLOB in a table column.
I can't change the charset of the session. I've tried to use a function
{code} FUNCTION convert_xml (pcl_xml IN CLOB) RETURN CLOB
[Code]....
This function apparently works, but when I try to validate the XML content (after I replace the encoding="ISO-8859-1" to encoding="UTF-8") the validation software tells me that I have some characters that should not be present in a file using UTF-8 encoding.
I got an exception when I was using sesame adapter to dump a turtle file which contains long texts as objects into oracle semantic database. The exception information is:

resolve problem with move lob objects ? I move table partition and lob (BLOB) from one tablespace to another :

I have a problem i need to convert a blob column contains pic file to long row
i had many tries but no one succeeded
----------------------------------- Source table | destination table id number | id number img blob | img long raw ------------------------------------
1 - INSERT INTO destination table SELECT id , img FROM Source table WHERE ROWNUM < 2
i have this error ORA-22835 Buffer too small for CLOB to CHAR or BLOB to RAW conversion (actual: 146092, maximum: 2000)
2 - INSERT INTO destination table SELECT id , dbms_lob.SUBSTR(img,0,2000) FROM Source table WHERE ROWNUM < 2
I'm creating a package function that would return the image from the table HR.PER_IMAGES.
Here's the table description of HR.PER_IMAGES IMAGE_ID NUMBER(15) IMAGE LONG RAW PARENT_ID NUMBER(15) TABLE_NAME VARCHAR2(30)
I have also created a simple PL/SQL code that would supposed to extract the value of the IMAGE column and store it in a variable then return it from a function.
DECLARE x LONG RAW; BEGIN SELECT image INTO x FROM per_images WHERE parent_id = :p_parent_id ; END;
However, I'm getting the "ORA-06502: PL/SQL: numeric or value error" message. I have tried retrieving an specific image using Oracle Reports Developer and when I queried it was able to render the image on the report page.
We are on Oracle 11.2.0.2 on Solaris 10. I have a procedure call that errors out with this error:
SP2-0027: Input is too long (> 2499 characters) - line ignored.
It is one single procedure but it takes too many long inputs in it. This giant procedure call -with some names changed - is as below -

SP2-0027: Input is too long (> 2499 characters) - line ignored.
when i look at the max(length(rowid)) from our tables - i see that the value is 18, while the length in the query is 38.
this seems to be the problem, but i don't understand why, and didn't see a proof of it in the documentation.
also, in the log of the application debug, i see another error on executing the exact statement - ORA-00054: resource busy and acquire with NOWAIT specified or timeout expired.
1. What can cause the ora-00972 error? is it the Rowid value?
2. How do i know what is the max length of rowid allowed?
3. is the first error somehow related to ORA-00054?
I am not sure but may be I need to set long size before running above query. But when I try to set long size gives below error. "The output from DBMS_METADATA.GET_DDL is a LONG datatype. When using SQL*Plus, your output may be truncated by default. Issue the following SQL*Plus command before issuing the

I am receiving a ORA-01489: result of string concatenation is too long error on the following code. The size of the MNO_NOTE fields is: MNO_NOTES_1 X(2000). I'd rather not modify the DB table column size, but rather that capacity of the "notes", or whatever structure the concatenated string is stored in. Could I use the substring method?
SELECT TO_DATE(TO_CHAR(mno_date_recorded,'yyyymmdd')|| TO_CHAR(mno_time_recorded,'0009'),'yyyymmddhh24mi') AS create_date, stf_id AS create_user, RTRIM(MNO_NOTES_1)|| RTRIM(MNO_NOTES_2)|| RTRIM(MNO_NOTES_3)|| RTRIM(MNO_NOTES_4)|| RTRIM(MNO_NOTES_5)|| [code]...
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.
