body: <p>I created a sequence in ORACLE 10g database</p>
  
  <pre><code>CREATE SEQUENCE "test_seq" 
  START WITH 1 INCREMENT BY 3 
  NOMAXVALUE NOMINVALUE NOORDER NOCYCLE NOCACHE;
  </code></pre>
  
  <p>I also have a table in database to use this sequence</p>
  
  <pre><code>CREATE TABLE USER_TEST
  (
     U_NAME   VARCHAR2 (100),
     PWD      VARCHAR2 (100),
     SR_NO    NUMBER
  )
  NOCACHE
  LOGGING;
  </code></pre>
  
  <p>But when inserting values in table using </p>
  
  <pre><code>INSERT INTO USER_TEST VALUES( test_seq.NEXTVAL,'QWERTY','1QWE')
  </code></pre>
  
  <p>it gives following error</p>
  
  <blockquote>
    <p>ORA-02289: sequence does not exist</p>
  </blockquote>
