As it is known, HTP.PRN procedure does not support clob data. None of the HTP.PRN procedures shown in below support CLOB data type as input.
HTP.PRN (cbuf IN VARCHAR2);
HTP.PRN (dbuf IN DATE);
HTP.PRN (nbuf IN NUMBER);
So, the following procedure provide to print clob data.
PROCEDURE HTPPRN(PCLOB IN OUT NOCOPY CLOB)
IS
V_TEMP VARCHAR2(32767);
V_CLOB CLOB := PCLOB;
V_AMOUNT NUMBER := 32000;
V_OFFSET NUMBER := 1;
V_LENGTH NUMBER := DBMS_LOB.GETLENGTH(PCLOB);
V_RESULT CLOB;
BEGIN
WHILE V_LENGTH >= V_OFFSET LOOP
V_TEMP:= DBMS_LOB.SUBSTR(V_CLOB, V_AMOUNT, V_OFFSET);
HTP.PRN(V_TEMP);
V_OFFSET := V_OFFSET + LENGTH(V_TEMP);
END LOOP;
END;
