Print CLOB content out as is in Oracle SQL script

To start with here is the bigger picture of the task I\'m trying to do. I need to create a xml file from the results of the particular SQL request and store it in a file on the

Answer 1

One possible approach is to do the following:

1. Create a database table with a single column and row of type CLOB.
2. On server, insert the produced XML into that table.

3. On client run the SQL*PLus script like this:

   SET WRAP OFF  
   SET HEADING OFF  
   SET ECHO OFF  
   SPOOL file_name.xml
   
   SELECT your\_clob\_column FROM your\_table;
   
   SPOOL OFF
   

That will dump your XML into file_name.xml After that, you will need to truncate you table by issuing:

TRUNCATE TABLE your\_table DROP STORAGE;

otherwise the table won't shrink even if you delete the line with CLOB.
