Hello. Can anyone tell me how to copy a table with a long column using PL/SQL? I tried the following code using a cursor but it errors out (ORA-06502: PL/SQL: numeric or value error)

The cursor copy works when I create the tmp table without the long and remove the long column from the cursor copy.

Hello,

I have written a little test procedure and it works ...
Here it is ... it runs without throwing an exception

PROCEDURE SCOTT.TESTPROC
IS
CURSOR cuSelect IS
SELECT feld1, feldlong FROM scott.testtab;
rRec cuSelect%ROWTYPE;
BEGIN
OPEN cuSelect;
FETCH cuSelect INTO rRec;
WHILE cuSelect%FOUND LOOP
dbms_output.put_line('Long = ' || rRec.feldlong);
FETCH cuSelect INTO rRec;
END LOOP;
CLOSE cuSelect;

EXCEPTION
WHEN OTHERS THEN
dbms_output.put_line('Fehler');
END;

Defintion feld1 = VARCHAR2
feldlong long

Database 8.1.6

Hello:

I modified you SQL to copy the records into a similar table and it also works. So it appears there is a problem with the data in the original table, although I do not know what it is.

Thanks for your help.

Hello,

could it be, that the LENGTH of the LONG field is greater that 32767 ?
I rember that %ROWTYPE with a LONG converts the field to char and
operation on VARCHAR > 32767 throws exceptions (that depends on the PL/SQL version you are using)

That is only an idea ....
