    From the examples:
    CREATE TABLE Dept_tab (
    Deptno NUMBER(3) PRIMARY KEY,
    Dname VARCHAR2(15),
    Loc VARCHAR2(15),
    CONSTRAINT Dname_ukey UNIQUE (Dname, Loc),
    CONSTRAINT LOC_CHECK1
    CHECK (Loc IN ('NEW YORK', 'BOSTON', 'CHICAGO')));
    Regards

    hiii,thanks
    table abc
    columnname-- status.
    status should be like this

    A-ADMINISTRATOR
    S-STAFF
    E-EXPIRED
    S-SUSPEND
    Above values should be valid by using "check" constraint.

    any one give me syntax
    thanks
