How to insert in long data type column

I would like to know how could I insert data in a long data type column.
Thanks

Don't use LONG, use CLOB instead. You can write to CLOBs using the DBMS_LOB package.

1. Export and import
2. Sql*Plus 'copy' command
It is a good idea to move from 'LONG' to 'CLOB'.

How to deal with LONG data type in RTF template

Hi,
I'm developing a PO request report in which I should print some attachments. The attachments are stored in the database in table fnd_attachments_long_text in column long_text which data type is LONG. In my case the content of the column long_text is always plain text.
The query I use to get the text from the table is something like:
select long_text
from fnd_documents_long_text
where <some_conditions....>
The query runs fine in SQL developer but when I run the XML report I get following error: "Stream has already been closed". The XML file generated is complete in its structure but the XML node which should contain the text of the attachment is empty, therefore I cannot print the attachment in the report.
I made some researches on metalink and I've found note 832903.1 which explains the same error I'm getting. Looks like I cannot execute more than 1 query using the same JDBC connection if one of these queries retrieves a LONG data type.
Any advice on how can I get the attachment text to show correctly in my report?
Thank you

Hi,
Thank you for your reply,
Yes, I tried to get the text as described in that article but maybe I'm missing something because my data template doesn't show the attachment text.
The article talks about support for BLOB, CLOB and RAW and at the end it states "but we do not have support for RAW and LONG column types at the moment - we're looking into that for a future release". So this makes me think that I won't be albe to retrieve my text since it's stored in a LONG column.
I think that the error I'm getting is not strictly related to XML publisher but it is in some way related to the JDBC connection used to get the data. Infact I have an old version of the same report I'm trying do develop which is made in Report Builder and it is retrieving the attachment text correctly.
Right now I'm trying to use the Report Builder engine to get the XML data and then use XML Publisher to create the PDF output. Anyway, if it is possible, I would like to avoid Report Builder and use only XMLP.
Thanks

How can I retrieve a LONG data type using ADO

In VB I am using an ADODB object to retrieve data from an Oracle table that has a LONG data type column...
specifically: SELECT TRIGGER_BODY FROM USER_TRIGGERS WHERE TRIGGER_NAME = 'MYTRIGGER'
I have tried using the GETCHUNK method but it only returns the first 150 or so characters no matter how
many times I call it???? here is the sample code I'm using........
Dim Cn As ADODB.Connection, Rs As ADODB.Recordset, SQL As String
Dim sChunk() As Byte
Set Cn = New ADODB.Connection
Set Rs = New ADODB.Recordset
Cn.CursorLocation = adUseServer
Cn.Open "Provider=OraOLEDB.Oracle.1;Password=hrzadmin;Persist Security
Info=True;UserID=hadmin;Data Source=xxx.local"
SQL = "SELECT trigger_body from user_triggers where trigger_name = 'MYTRIGGER'"
Rs.Open SQL, Cn, adOpenStatic, adLockReadOnly
Debug.Print Rs!trigger_name
Debug.Print Rs!trigger_body
sChunk = rs.Fields("trigger_body").GetChunk(500)
Debug.Print sChunk

I have a similar code which works for chunk size >400,
The image I am trying to retrieve is huge so the chunksize is also more.
Did you try with any non meta table?
For your reference I am pasting my application code below.
Hope it helps.

Yes Prathap, I need to update a single column of type number in the search results table.but each of that column value would be updated with different values like one row in that column will take a value 325 while another will take 500 etc based on user input.
Your help in this is very much appreciated, Thanks in advance !

Hi
my problem is, for each job_id there is many users. Oh that's something completlty different...
I Strongly Recommand to_
1.*create 2 tables Jobs & users*
2.*create a relation between them* 1 to many to get for each job more than a user that's the way that Must be -- execuse me the bad design of the db pulled u into this trap -
3.then u can deal with it normally no need to a sample code but just a form with Jobs as (Master) and Users as (detail) with a relation and with a simple query u can display each job_id is for many users.
no null values no commas r needed.
Hope this helps...

Need to convert long data type to varchar2

I need to convert a long datatype in an existing table to a
varchar2, in either another table or view. I have a 3rd party
application which needs to query the data in the long data type,
but it can "handle" the long.
What is the best way to do this? I tried to make a trigger, but
I must be missing something. Here is the trigger.
CREATE OR REPLACE TRIGGER "PROD".SV_GET_RTG_COMNT
BEFORE INSERT OR UPDATE ON PROD.RELS_RTG_SEQ_COMNT
FOR EACH ROW
WHEN (OLD.rels_rtg_no = NEW.rels_rtg_no)
DECLARE
-- DECLARE VARIABLES
RTG_COMNT_VAR VARCHAR2(32);
RTG_COMNT_LONG LONG;
BEGIN
Select COMNT_TXT into RTG_COMNT_LONG
from rels_rtg_seq_comnt;
RTG_COMNT_VAR := 'TEXT' || substr(RTG_COMNT_LONG,1,32);
-- If INSERTING
Insert into SV_RTG_SEQ_COMNT (print_cd, comnt_no,
seq_no, rtg_no, comnt_txt) values
(:new.print_cd, :new.comnt_no, :new.seq_no, :new.rels_rtg_no,
rtg_comnt_var);
END;
I tried to use the substr command on the comnt_txt in view but
received an invalid datatype error.
Any help would be greatly appreciated.

end;
Please help me on this.
Thanks in advance.

LONG columns cannot appear in certain parts of SQL statements:
WHERE clauses, GROUP BY clauses, ORDER BY clauses, or CONNECT BY clauses or with the DISTINCT operator in SELECT statements
The UNIQUE operator of a SELECT statement
The column list of a CREATE CLUSTER statement
The CLUSTER clause of a CREATE MATERIALIZED VIEW statement
SQL functions (such as SUBSTR or INSTR)
Expressions or conditions
SELECT lists of queries containing GROUP BY clauses
SELECT lists of subqueries or queries combined by the UNION, INTERSECT, or MINUS set operators
SELECT lists of CREATE TABLE ... AS SELECT statements
SELECT lists in subqueries in INSERT statements

Using DBMS_DATAPUMP with LONG data type

I've got a procedure below that calls the DBMS_DATAPUMP procedure using a REMOTE_LINK to move a schema from one database to another. However, a couple of the tables within that schema have columns with the LONG data type. And when I run it I get an error saying that you cannot move data with the LONG data type using a REMOTE LINK. So no data in those particular tables gets moved over.
Has anyone else had this issue? If so, do you have a work around? I tried adding a CLOB column to my table and setting the new CLOB to equal the LONG, but I couldn't get that to work either...even when I tried using a TO_LOB. If I could get that to, then I could just drop the LONG, move the schema, then recreate the LONG column on the opposite side.

But the application we have that uses the database cannot be changed to read from a CLOBWhy can't you change the application?
Well, anyway you should point out to your superiors that Oracle documented years ago to not use LONGS anymore...
http://download.oracle.com/docs/cd/B19306_01/server.102/b14220/datatype.htm#sthref3806
It clearly states:
LONG Datatype
Note:
Do not create tables with LONG columns. Use LOB columns (CLOB, NCLOB) instead. LONG columns are supported only for backward compatibility.
Oracle also recommends that you convert existing LONG columns to LOB columns. LOB columns are subject to far fewer restrictions than LONG columns. Further, LOB functionality is enhanced in every release, whereas LONG functionality has been static for several releases.
How do I go from CLOB to LONG?I'm sorry, cannot help you on that one, I don't think you can do that at all (Oracle wants us to stop using LONGS, so, it's a one-way conversion...):
http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:1037232794454#15512131314505
So: NO built_in, you'll need to write a program if the clob is ALWAYS LESS THAN 32k in size, you can use plsql..but is that the case in your case? Only you know that.
I believe that question is still unanswered on this forum, but you might try searchin for answers on this forum, and
the 'Database-General' forum: General Database Discussions
Perhaps you can google a Q&D workaround...
( And consider convincing your collegues to just convert your LONGS to LOBS)

Getting past days data based on DATE data type column

Hi,
When you say "last 2 days" do you mean the 48 hours right before run-time?
If so, you want to compare col to SYSDATE:
select *
from    tbl
where   col > SYSDATE - 2
and     col <= SYSDATE
;If you mean the "last 2 days" before some other event, then replace SYSDATE with that date in both places above.
If you were trying
where   col > col - 2then you should have been getting all rows that have a non-NULL col. If you were getting no results, then something is very wrong.
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all the tables involved, and the results you want from that data.
If the results depend on when you run the query, then give a couple of different examples, with the run-time. for example "If I run this at 03:00:00 on July 1, 2012, then I should get ... but if I run ir at 15:00:00 on July 1, 2012, then the results should be ...".
Explain, using specific examples, how you get those results from that data.
Always say what version of Oracle you're using.

When you do this, there is no fundamental difference between "08:00:00" and "here's your sign".
Data should always be stored in the correct data type. For dates and times, that data type is either DATE or TIMESTAMP. Period.
in this format: 08:00:00
now i have to insert this value in timestamp column in table. how to insert this value in timestamp column?
Hopefully as remediation to the original bad design.
thanks

Retrieve data from LONG data types

Hi,
I am trying to retrieve data from LONG data types with following query.
select * from all_views where upper(text) like '%TABLE_NAME%';
In above query text column has long datatype. This query works for varchar, but it returns an error for long.
How can I modify the query so that it returns data from text column.
Thanks in advance,
Aditya

You can't use any expressions against LONG. One solution is to use PL/SQL:
BEGIN
    FOR v_rec IN (SELECT * FROM ALL_VIEWS) LOOP
      IF UPPER(v_rec.text) LIKE '%TABLE_NAME%'
        THEN
          DBMS_OUTPUT.PUT_LINE(v_rec.text);
      END IF;
    END LOOP;
END;
/SY.

ADF View Object query to use Oracle LONG data type

Hi,
I'm using a view object that uses Oracle LONG data type.The following exception is thrown
*"java.sql.SQLException: Stream has already been closed"* and it is not fetching the correct data.
I have searched in many forums,they suggested to use LOB instead of LONG as LONG is deprecated. But in my case I can't avoid using LONG as some of my legacy applications using the same DB.
Please suggest me a way
Thanks in Advance
Felix

Thanks for your reply Arun,
I have solved this problem using the solution suggested by this blog [AskTom-Link|http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:839298816582]
In the above blog link,they have suggested to convert Long to Varchar by functions and asked to use this function in the column.
Thank you all guys who have seen this post.
