Function to covert LONG to CLOB

Can you please tell me the name of the function through which I can change the LONG datatype to CLOB.

There is a function called to_lob(). You can use it only inside a subquery of an INSERT statement.
Try doing something like this..
1. Create an equivalent table except that instead of LONG use a CLOB datatype.
2. Insert into that table using something like...
INSERT INTO table_name SELECT a, b, to_LOB(long_column), c FROM original_table;
3. DROP ur table and rename the other table.
Or you can do some other trickery.

Using long vs. clob datatype with Oracle 8.1.7 and interMedia

I am trying to determine the best datatype to use for a column I
wish to search using the interMedia contains() function. I am
developing a 100% java application using Oracle 8.1.7 on Linux.
I'd prefer to use the standard JDBC API's for PreparedStatement,
and not have to use Oracle extensions if possible. I've
discovered that there are limitations in the support for LOB's
in Oracle's 100% java driver. The PreparedStatement methods
like setAsciiStream() and setCharacterStream() are documented to
have flaws that may result in the corruption of data. I have
also noticed that socket exceptions sometimes occur when a large
amount of data is transferred. If I use the long datatype for
my table column, the setCharacterStream() method seems to
transfer the data correctly. When I try to search this column
using the interMedia contains() function, I get strange
results. If I run my search on Oracle 8.1.6 for Windows, the
results seem to be correct. If I run the same search on Oracle
8.1.7 for Linux, the results are usually incorrect. The same
searches seem to work correctly on both boxes when I change the
column type from long to clob. Using the clob type may not be
an option for me since the standard JDBC API's to transfer data
into internal clob fields are broken, and I may need to stick
with standard JDBC API's. My customer wishes to purchase a
version of Oracle for Linux that will allow us to implement the
search capability he requires. Any guidance would be greatly
appreciated.

I've finally solved it!
I downloaded the following jre from blackdown:
jre118_v3-glibc-2.1.3-DYNMOTIF.tar.bz2
It's the only one that seems to work (and god, have I tried them all!)
I've no idea what the DYNMOTIF means (apart from being something to do with Motif - but you don't have to be a linux guru to work that out ;)) - but, hell, it works.
And after sitting in front of this machine for 3 days trying to deal with Oracle's, frankly PATHETIC install, that's so full of holes and bugs, that's all I care about..
The one bundled with Oracle 8.1.7 doesn't work with Linux redhat 6.2EE.
Don't oracle test their software?
Anyway I'm happy now, and I'm leaving this in case anybody else has the same problem.
Thanks for everyone's help.

Function keys no longer working with a new keyboard...

I got a new keyboard and my function keys no longer work with it. I am used to have them used in the standard format, i.e. F10-F12 control the voume, etc. I have the "Use all f1,f2, etc." button clicked. I have also tried restarting my computer. Any thoughts?

Try doing a SMC reset and PRAM reset.
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

How to copy a table with LONG and CLOB datatype over a dblink?

Hi All,
I need to copy a table from an external database into a local one. Note that this table has both LONG and CLOB datatypes included.
I have taken 2 approaches to do this:
1. Use the CREATE TABLE AS....
SQL> create table XXXX_TEST as select * from XXXX_INDV_DOCS@ext_db;
create table XXXX_TEST as select * from XXXX_INDV_DOCS@ext_db
ERROR at line 1:
ORA-00997: illegal use of LONG datatype
2. After reading some threads I tried to use the COPY command:
SQL> COPY FROM xxxx/pass@ext_db TO xxxx/pass@target_db REPLACE XXXX_INDV_DOCS USING SELECT * FROM XXXX_INDV_DOCS;
Array fetch/bind size is 15. (arraysize is 15)
Will commit when done. (copycommit is 0)
Maximum long size is 80. (long is 80)
CPY-0012: Datatype cannot be copied
If my understanding is correct the 1st statement fails because there is a LONG datatype in XXXX_INDV_DOCS table and 2nd one fails because there is a CLOB datatype.
Is there a way to copy the entire table (all columns including both LONG and CLOB) over a dblink?
Would greatelly appriciate any workaround or ideas!
Regards,
Pawel.

Hi Nicolas,
There is a reason I am not using export/import:
- I would like to have a one-script solution for this problem (meaning execute one script on one machine)
- I am not able to make an SSH connection from the target DB to the local one (although the otherway it works fine) which means I cannot copy the dump file from target server to local one.
- with export/import I need to have an SSH connection on the target DB in order to issue the exp command...
Therefore, I am looking for a solution (or a workaround) which will work over a DBLINK.
Regards,
Pawel.

Literal too long when inserting 4000 chars to long or clob

How to avoid getting the 'literal too long' error when inserting a string >4000 chars to a long or clob field?

A string literal can only be 4000 characters. To insert into a LOB, you need to use the dbms_lob package.

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;

Seems the gyroscope function is no longer working on my iPhone 5c. Suggestions?

Seems the gyroscope function is no longer working on my iPhone 5c. Suggestions?

Thank you so much for this reply. I had already seen this reboot suggestion and actually tried it. During the night I realized that I had phrased the question wrong because I really had the issue of getting my iPhone to change to LANDSCAPE mode. For some reason I asked for help on the gyroscope Thinking that the gyroscope controlled this feature. I found that I had accidentally turned on the "orientation lock" and by bringing up the control panel from the bottom of the screen I was able to find this lock button and correct the problem. The truth is ---- the iPhone scree is so small that I was not able to see this little lock symbol at all. I found this symbol on my iPad and transferred the knowledge to my iPhone. Everything is working fine now And I thank you very much for taking the time to write to me. SuzanneVA

Procedure to convert from long to clob

please need to procedure migrate data from long to clob,with variables
V_SRC_TABLE (LONG) to V_TRAGT_TABLE (CLOB)
SOURCE AND TARGET TABLE HAVE TWO COLUMNS
SOURCE_TABLE
VARACHAR2
LONG
TARGET_TABLE
VARACHAR2
CLOB

Hi,
assuming you want to convert data always from source_table to target_table knowing the column names, let's say:
SQL> CREATE TABLE source_table(col1 VARCHAR2(10), col2 LONG);
Table created.
SQL> CREATE TABLE target_table(col1 VARCHAR2(10), col2 CLOB);
Table created.You can just copy the data using SQL:
INSERT INTO target_table SELECT col1, TO_LOB(col2) FROM source_table;Or, as a procedure:
CREATE OR REPLACE PROCEDURE migrate_to_clob IS
BEGIN
EXECUTE IMMEDIATE 'INSERT INTO target_table SELECT col1, TO_LOB(col2) FROM source_table';
END;Hope it helps.

HELP! - Converting LONG to CLOB in PL/SQL

can i pass in a LONG as a parameter to a stored procedure and in
the stored procedure convert or assign it to a CLOB column? i
have tried passing in a CLOB as an input parameter using OO4O
without any success. i am using the oracle oledb provider
currently but may convert it over to using OO4O if i have to. i
know i can pass in a LONG via ADO as an adLongVarChar datatype,
but i am not sure what to do with the LONG inside the stored
procedure. if anyone knows how to get a LONG into a CLOB could
you please post some very basic sample PL/SQL code.
if there is an easier way please let me know!
the reason i am using CLOB's is because i need more than one
LONG in certain tables, and you can only have 1 LONG per table.
thanks

i should have mentioned i am using oracle 8.1.7.2.1 and when i
try to use TO_LOB() i get "Identifier TO_LOB must be declared."
so i am assuming this is an oracle 9 function. is this correct?

Long and clob datatype

Hello Gurus
we are working on oracle 8.1.4.0.in our database i have a table that contain a long column and a clob cloumn. i need backup of this table so that i can create the same table with data in other schema. Is there any recommmanded way. Can use copy or i need to use an export backup .
thanks

If possible, try to upgrade your long columns to lob. Working with long columns will severely limit the possibilities of adopting new features. It would have been easier to use the
ALTER TABLE MOVE ... command.

String literal too long for CLOB

Q1. I would like to insert text of 10000 chars into a column with data type CLOB via an ASP program connecting to Oracle9i. Which data type is most appropriate to input 10000 chars into a column?
Q2. I would like to insert text UNICODE Traditional Chinese into a column with data type NCLOB, data is stored but when it is retrieved via Internet Explorer, strang chars are displayed instead of Traditional Chinese. Can any one tell me how you could store Chinese Chars, retrieve and display Chinese Chars properly in Internet Exlplorer via ASP program?

10,000 characters is too long for a varchar2 column, but CLOB's will let you store a couple of Gb.
When you're dealing with inserting and retrieving Traditional Chinese characters, you need to ensure that the NLS settings on your client and on your database are such that the character sets on both machines actually support the characters in question. I'm guessing that your client machine isn't configured to support those characters. If you go to http://tahiti.oracle.com and search for NLS, you'll get a boat-load of documents about how to approach this sort of problem If you haven't reviewed these yet, I'd strongly suggest doing so.

Function to retrieve long text in FI document for payment file

Hi
Is there a function i could use to retrieve the long text in the invoice document for the payment reference field in the payment file?

Possiblity could be that you have passed the wrong object name id or any parameters.
See below the similar code.
If you want to know the correct tdobject and correct tdname combinations go to table STXH and under name give the document number ie 1900000000 ie docno then you will come to know the correct tdname and object and tdid from which you can use the read_text function module

           tdname   TYPE thead-tdname,
           tdid     TYPE thead-tdid,

DATA : lines    TYPE STANDARD TABLE OF tline INITIAL SIZE 0,
         wa_lines TYPE tline.
CONCATENATE bkpf-bukrs bkpf-belnr bkpf-gjahr INTO tdname.
