Print CLOB data using Oracle PL/SQL

Objective:

To print clob data.

Solution:

Step 1: Create plsql procedure to print the clob.

 CREATE OR REPLACE PROCEDURE print_clob_to_output (p_clob IN CLOB)
 IS
   l_offset     INT := 1;
 BEGIN
   dbms_output.put_line('Print CLOB');  
    loop
        exit when l_offset > dbms_lob.getlength(p_clob);
        dbms_output.put_line( dbms_lob.substr( p_clob, 255, l_offset ) );
        l_offset := l_offset + 255;
    END LOOP;
 END print_clob_to_output;

 This query will print the complete clob data.

Step 2: Call the procedure.

 DECLARE
  l_xml CLOB;
BEGIN
  SELECT dbms_xmlgen.getxml('select * from emp') xml 
    INTO l_xml 
    FROM dual;
  
  print_clob_to_output (l_xml);

END;
