Help! Update a column in LONG data type

I am looking for help on how to update a column with the long data type in a oracle 7.34 table on sun Solaris 2.6.:
SQL> desc searchengine;
Name Null? Type
ENGINE_ID NOT NULL NUMBER(38)
ENGINEHTML LONG
SQL> set long 10000
Then when I run the following update statement I always get the error
ERROR at line 1:

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 !

Urgent!!!----Update a field of Long data type via trigger

While it is obvious that it is no way for an Oracle trigger to update a field of a Long data type, is it a feasible way to call a java stored procedure from the trigger to achieve that purpose? If not, can you suggest any good solution to this?
Thanks so much.

Scripter -
When you try to do a Set and Put, it is always good to explicitly set the statement's cursor type to something other than forward only, like keyset, and the lock type to something other than read-only. See if that helps...

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

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.

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.

create another table with clob datatype
1)create table clob_tab(pkval number,clob_col clob);
2) insert into clob_tab (select pkval,to_lob(long_col) from
long_tab);
3) use dbms_lob package to do string manipulation using
substr,instr functions on clob column.

How to insert data in a column with uniqueidefier data type

Guys,
I need insert data in a column with uniqueidefier data type, when i am trying to that getting error.
error message says: "Conversion failed when converting from a character string to uniqueidentifier."
I have data in table a col1,col2,col3,col4 - col3,col4 has datatype as varchar and i am updating table b columns col1,col2 with table a col3 and col4.
Please guide how to do it.

Hi,
Not any String can be convert to uniqueidentifier.
1. you have to make sure u use a value which is fir to be uniqueidentifier
2. Use convert or cast in the insert query in order to convert the string into uniqueidentifier
insert X ... convert(uniqueidentifier, 'string which fit to be convert to uniqueidentifier')
Please post DDL+DML for more specific help
DDL = Data Definition Language. In our case that is, CREATE TABLE statements for your tables and other definitions that are needed to understand your tables structure and there for let us to test and reproduce the problem in our server. Without DDL no one
can execute any query.
How to get DDL: Right click on the table in Object Explorer and select script table as CREATE. Post these create table scripts here.
DML = data manipulation language is a family of queries used for manipulating the data it self like: inserting, deleting and updating data. In our case we need some sample data in order to check the query and get result, so we need some indert query for
sample data.
If you post a "create query" for the tables and "insert query" with some sample, then we could help you without Assuming/Guessing. There is a reason that DDL is generally asked for and expected when discussing query problems - it helps
to identify issues, clarify terminology and prevent incorrect assumptions. Sample data also provides a common point of reference for the discussion. A script that can be used to illustrate or reproduce the issue you have, will encourage others to help.

Error in getting Long data type from Table

Hi All,
I have one table say xx_long. In this table one column is having Long data type.
Now I want this values will get in to the PL/SQL variable. I taken variable data type as long but it is showing error "ORA-00997: illegal use of LONG datatype".
Sample code with which I tried:
declare
a long;
begin
select slno into a from xx_long where slno = 100;
dbms_output.put_line('Value:'||a);
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.
Here's my procedure....

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)

Need help regarding the maximum limit for data type

Hi,
this is Sravan. for my application am inserting the bulk data in XML format into a column of Database table.
the sample inserted XML data will be in format... like
'<ACC count = "10">
<Acc ac_no = "1111111111" cn_nr = "US" eflag = "Y" />
<Acc ac_no = "1111111111" cn_nr = "US" eflag = "Y" />
<Acc ac_no = "1111111111" cn_nr = "US" eflag = "Y" />
<Acc ac_no = "1111111111" cn_nr = "US" eflag = "Y" />
<Acc ac_no = "1111111111" cn_nr = "US" eflag = "Y" />
<Acc ac_no = "1111111111" cn_nr = "US" eflag = "Y" />
<Acc ac_no = "1111111111" cn_nr = "US" eflag = "Y" />
<Acc ac_no = "1111111111" cn_nr = "US" eflag = "Y" />
<Acc ac_no = "1111111111" cn_nr = "US" eflag = "Y" />
<Acc ac_no = "1111111111" cn_nr = "US" eflag = "Y" />
</ACC>'
this data in XML can have more than 1000 accounts.
now, i need to take a Parameter value from XML node and write into a file. for this i have written a procedure by looping the Nodes from XML data and building Dynamic Query like..
if nvl(v_int, 0) > 0 then
v_sql := '';
     for v_count in 1..v_int
     loop
     if v_sql is null then
          v_sql := 'select extractvalue(empdetails, ''/ACC/Acc' || v_count ||'/@ac_no'')||extractvalue(empdetails, ''/ACC/Acc' || v_count
||'/@cn_nr'')||extractvalue(empdetails, ''/ACC/Acc' || v_count ||'/@eflag'') string from sample1';
     elsif v_sql is not null then
               v_sql := v_sql || ' union all select extractvalue(empdetails, ''/ACC/Acc' || v_count ||'/@ac_no'')||extractvalue(empdetails, ''/ACC/Acc' || v_count
||'/@cn_nr'')||extractvalue(empdetails, ''/ACC/Acc' || v_count ||'/@eflag'') string from sample1';
          end if;
     end loop;
end if;
i will get this variable "v_int" from <ACC count = "10"> ACC count Attribute, here 10 is the value for v_int variable but in real time the variable value can be more than 1000.
at the time of Building Dynamic Query I make using the Variable v_SQL which is of Data Type "Long",
this variable stores dynamic query which is build at the time of executing procedure but this v_sql Variable is throughing Exception that ....
"numeric or value error Character String Buffer is Too Small"... but Long Data type will store upto 2GB..
this variable cant able to hold much data which is dynamically build.
will you please help me to resolve this issue Or will u suggest me another method to pick the data from XML column.
thanks,
sravan.

i changed the code, now its working fine.
direct assigning the dynamic query to a Clob variable raised error.
for dynamic query building i used another variable and assigned this variable value to actual query variable.Nice!

REPLACE function on a long data type

How can I use the replace function on a long data type?
I am getting ORA-00932: inconsistent datatypes: expected CHAR got LONG

Thanks so much dainge! Your example helped me to do it. I guess the trick is to put the long datatype into the declared variable first. This is what worked (of course commit after):
declare
l long;
begin
select rppl_sql_statement into l
from rppl
where rppl_slct = 12128;
l := replace(l,'ROPPL96','ROPPL97');
update rppl
set rppl_sql_statement = l
where rppl_slct = 12128;
end;

Create Tabel having LONG Data Type

HI Team,
I want to create table but for table i have 2 LONG data type is throwing error message please give the light

JustinCave wrote:
1) When you're getting an error, it's always helpful to include the error. Otherwise, we have to guess. And if we guess wrong, our answers will be incorrect and we'll waste everyone's time. Including the Oracle version is also useful.
2) Why, oh why would you want to use the LONG data type? That type has been depricated since 9.0.1. It was replaced by the CLOB data type (assuming you are storing large amounts of character data-- BLOB would be the replacement for LONG RAW columns). Data in a LONG is terribly difficult to work with in PL/SQL.
3) My recollection is that one of the (many, many, many) restrictions on a LONG is that you can only have 1 per table. I'm guessing that is the error you're getting (though if you post the error, I wouldn't have to guess).
Justin
Even oracle should probably re-consider its data dictionary views not to use long datatype.
e.g. Does not look perfect when you see LONG datatype for TEXT column in dba_views/all_views/user_views and that too in latest version Oracle 12c

Manik.

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.

How to display images in BI Publisher from a LONG data type

We are storing images in Oracle Database as LONG data type. When I am giving query in BI Publisher and view the XML generated, I am getting the following error.
name was started with an invalid character. Error processing resource 'http://.......
<X_SIGNATURE>"N!0$$$$$$$#B!0$$$"X$$$$!3$$$!2$$#a$$$!1$!1$$$$$d$$$$#7$"X!0$"}@E$e"1"XM">K#@!P!P!Ga}!1!@!P!C#C"O!>...
Can anyone suggest the solution?

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...

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

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.

Felix
