आशा है कि यह उदाहरण स्पष्ट रूप से दिखाता है कि मैं क्या समझाने की कोशिश कर रहा हूं।
SET SQLBL ON;
SET DEFINE OFF;
CREATE TABLE CLOB_TEST
(
clob_in CLOB
);
INSERT
INTO CLOB_TEST VALUES
(
'I am working as a DBA and senior database resource in L&T Infotech in Pune India'
);
SELECT DBMS_LOB.SUBSTR(CLOB_IN,3000) ot FROM CLOB_TEST;
-----------------------------OUTPUT------------------------------------------
OT
