    Selecting a CLOB into .csv

    Hi All,
    I am currently trying to select all of the date in a table and spool it to a csv file. The issue is that one of the fields is a clob. When I run it I only get the first 80 characters of the record. When I take out the CLOB I get all the other fields (with the clob it cuts off after about 6 fields.) I know CLOBs can be tricky to work with, but I hope the solution is simple. Here's my SQL:

    set pagesize 0
    set termout off
    set trimspool on
    set linesize 32767
    set feedback off
    set trimout on
    set underline off
    set time off
    set timing off
    SET NEWPAGE 0
    SET SPACE 0
    SET ECHO OFF
    SET VERIFY OFF
    SET HEADING OFF
    SET MARKUP HTML OFF
    SET tab off

    /* Data for Extract */

    spool foo.csv
    select
    ',"'||TRIM(E_PARTNER_KEY)||'",'||
    '"'||TRIM(E_NAME)||'",'||
    '"'||TRIM(E_WEBSITE)||'",'||

    /* Formatting of this column is off due to SQL-PLUS limitations, there is a large amount of whitespace between the previous column and this one. This field also can't be concatenated with the previous since it is a CLOB column. So for now, we have to live with a large amount of spaces embedded between fields. Also, the trailing quote at the end of the line is not showing up, there appears to be a problem with Concatenating text to the tail end of a CLOB. So, for the short term we are appending a quote to the end of the line in post-processing
    */
    ',"'||substr(J_DESCRIPTION,1,DBMS_LOB.GETLENGTH(J_DESCRIPTION))||'"'

    Try:

    SET LONG 32000

    That helped. Thanks so much. The only other problem I have now is that when I try to append the final double quote at the end, a hard return is inserted right before that. I need the return after the quote.

    For example, each record comes out looking like:

    ,"cxcore","CoreTechs, Inc","","Engineering - Other","dpk_cxcore.090104","du_cxcore.090104","","Hide Everything","Not","Specified","","cxcore.090104","HVAC Plumbing/Piping Sr. Engineer or Project Manag",Yes,"Job","No",08/05/04,09/04/04,"50-70 or 70-95k.","URL","","",No,08/05/04,09/04/04,No,"Seattle","WA","United States of America","Mechanical Construction/Engineering Company needs Senior Engineers and/or Project Managers with a proven track record in innovative design and management on large commercial projects.

    Cool -1?

    Did you try this:

    substr(J_DESCRIPTION,1,DBMS_LOB.GETLENGTH(J_DESCRIPTION)-1)||???

    Hi, I know this is a very very old thread but I can't find any solution in the web. This thread is the closest thing I found to answer my problem.

    So here it goes. I want to extract data and save it into a CSV file. One column from the table is CLOB. I followed the solution in the previous post and was able to extract the CLOB column but I encountered a different problem. Instead of giving me a single line for every row of data, the CSV file contains multiple lines per row of data. How can I solve this problem? Below is the sample of my SQL code:

    SET LINESIZE 32000;

    SET NEWPAGE 0;
    SET SPACE 0;
    SET PAGESIZE 0;
    SET LONG 32000;
    SET ECHO OFF;
    SET FEEDBACK OFF;
    SET HEADING OFF;
    SET TERMOUT OFF;
    SET VERIFY OFF;
    SET TRIMSPOOL ON;

    SELECT NVL(ID, ' ') || '|' ||
    NVL(AGTFLAG, 0) || '|' ||
    NVL(ATTEMPTS, 0) || '|' ||
    NVL(DTVALID, SYSDATE) || '|' ||
    NVL(FNAME, ' ') || '|' ||
    NVL(CODE, ' ') || '|' ||
    NVL(LSTLOGIN, SYSDATE) || '|' ||
    NVL(LNAME, ' ') || '|' ||
    NVL(LSTPWRDUPDT, SYSDATE) || '|' ||
    NVL(LSTPDTE, SYSDATE) || '|' ||
    NVL(LGNFLAG, 0) || '|' ||
    NVL(MNTNDBY, ' ') || '|' ||
    NVL(MNAME, ' ') || '|' ||
    NVL(PWRD, ' ') || '|' ||
    NVL(ID, ' ') || '|' ||
    NVL(REMARKS, ' ') || '|' ||
    NVL(SESSION, ' ') || '|' ||
    NVL(STAT, ' ') || '|' ||
    NVL(TTLATTEMPTS, 0) || '|' ||
    NVL(CREATIONDTE, SYSDATE) || '|' ||
    NVL(BACKUPID, 0) || '|' ||
    NVL(AUTHORIZATIONLMT, 0) || '|' ||
    NVL(PWSOURCE, ' ') || '|' ||
    NVL(SUBSTR(PWCERTIFICATE, 1, DBMS_LOB.GETLENGTH(PWCERTIFICATE) - 1), ' ') || '|' ||
    NVL(EMAILADD, ' ') || '|'
    FROM USER
    WHERE CODE = '&1';

    This is the sample result that I'm getting
