Hi,
I am trying to dump the content of a view into a text file. I am following the steps below
1. select the colmn to cursor
2. Fetch cursors into variables
3. concatinate all variables into a single string
4. Write to string using UTL_FILE package.
I have the problem in step 3, where I am trying to concatinate all the cursor values to a single varchar variable.
I get the following error
ERROR at line 1:
ORA-20000: ORU-10027: buffer overflow, limit of 2000 bytes
ORA-06512: at "SYS.DBMS_OUTPUT", line 106
ORA-06512: at "SYS.DBMS_OUTPUT", line 65
ORA-06512: at "MNDB.RESPONSE_FILE", line 310
ORA-06512: at line 1
Lenght of all the columns in the view will not exceed 1200 characters
Please help me;

Looks like you are using dbms_output for something. By default, you can only spool 2000 bytes using dbms_output. You can increase it by using the dbms_output.enable method:
dbms_output.enable(1000000);

Hi!
Ok, here is what I know:
DBMS_OUTPUT has a buffer, which default size is 20000. Your buffer size is set as 2000, the minimum possible.
Here a note from the DBMS_OUTPUT header in the Oracle documentation:
"Messages sent using DBMS_OUTPUT are not actually sent until the sending subprogram or trigger completes. There is no mechanism to flush output during the execution of a procedure. "
That mean that your buffer don't get clear until the end of your PL-SQL block, so the problem is not the lenght of one of your line, but the sheer size of all the line of your view together.
But there is a way to solve the problem: change the size of the buffer. You could set a size of maximum 1,000,000 using the following:
DBMS_OUTPUT.ENABLE(your_new_size_in_integer);
It solve my problem not long ago: hope it help you as well!
