    sqlplus-need help

    This is my table. I need to add a null constraint using alter table.

    alter table gradstudent
    add constraint gradstudent_sfname_nn not null(s_fname);

    alter table gradstudent
    add constraint gradstudent_slname_nn not null(s_lname);

    What am I doing wrong? Is it possible to put it in one statement?

    Name Null? Type
    ----------------------------------------- -------- ----------------------------
    S_ID NUMBER(3)
    S_LAST VARCHAR2(10)
    S_FIRST VARCHAR2(10)
    S_MI CHAR(1)
    S_ADD VARCHAR2(25)

    hum, are you specifying the right column name in your add constraints?
    s_fname, s_lname are not the same as S_LAST and S_FIRST of your select...

    yes, the database just prints everythimg in caps.
    Here is my table part of the script. Would it be better to use a modify statement?

    create table student
    (
    s_id number(3),
    s_last varchar2(10),
    s_first varchar2(10),
    s_mi char(1),
    s_add varchar2(25)
    );

    that's my point, it's not just diffrent caps, one is "s_last" the other is "s_lname"! Same with "s_first" and "s_fname"...
