    Hi Friends,

    Can I use default contriant to assign sequence no. to
    a column?

    e.g.

    CREATE TABLE EMP
    (IDNO NUMBER DEFAULT SEQ1.NEXTVAL,
    HIREDATE DATE DEFAULT SYSDATE,
    NAME VARCHAR2(30) NOT NULL)
    /

    I got error in line #2.... but #3 works.

    SOS please.

    well, I can select both using DUAL....

    SQL> SELECT SYSDATE FROM DUAL;

    SYSDATE
    ---------
    04-JUL-02

    SQL> SELECT SEQ1.NEXTVAL FROM DUAL;

    NEXTVAL
    ----------

    No, sequence can not be referenced for default value for the column.
