ORA-00947: not enough values tips

Oracle Error Tips by Burleson Consulting


Oracle docs note this about ORA-00947:

  • ORA-00947 not enough values

    Cause: This error occurs when a SQL statement requires two sets of values equal in number, but the second set contains fewer items than the first set. This can occur in a WHERE or HAVING clause in which a nested SELECT returns too few columns as in:


    Another common cause of this error is an INSERT statement in which the VALUES or SELECT clause does not contain enough values needed for the INSERT, as in


    Action: Check the number of items in each set and change the SQL statement to make them equal.

  • On Oracle DBA-Forums, has a great example of ORA-00947, and a resolution. 
  • Question:
  • How do I resolve ORA-00947 in this situation?
  • SQL> run 1
    1 merge into aim m1
    2 using flataim m2 on ( = m1.snam)
    3 when matched then update set m1.snam =,
    4 m1.fnam = m2.fn, m1.lnam = m2.ln, m1.midnam =,
    5 m1.maidn =, m1.cntry =, =,
    6 =, m1.empt =, m1.nick = m2.nk,
    7 = m2.zp, m1.street = m2.rd
    8 when not matched then insert ((select aimsq.nextval from dual),
    9 m1.fnam, m1.lnam, m1.midnam,
    10 m1.maidn, m1.cntry, m1.state,, m1.nick,
    11, m1.street, m1.snam, m1.empt)
    12 values ( m1.fn, m2.ln,,,,,
    13* m2.nk, m2.zp, m2.rd,,;
    when not matched then insert ((select aimsq.nextval from dual),
    ERROR at line 8:
    ORA-00947: not enough values


    Because the ORA-00947 error signifies that there are not enough values passing through INSERT, the insert in the aim table should match all columns.  Here is an example, using snam:

    when not matched then insert
    m1.fnam, m1.lnam, m1.midnam,
    m1.maidn, m1.cntry, m1.state,, m1.nick,, m1.street, m1.snam, m1.empt)
    m1.fn, m2.ln,,,,,,
    m2.nk, m2.zp, m2.rd,,;


    Also, keep in mind while troubleshooting for ORA-00947, that the (select aimsq.nextval from dual) needs to be on the VALUES side.

    MOSC also offers information on ORA-00947 when it occurs along with attempting to add an insert statement, with all necessary columns properly stated. Here is an example:

    SQL> create table mytab (c1 date, c2 number);

    Table created.

    SQL> insert into mytab values(to_date('01-MAY-95',1));
    insert into mytab values(to_date('01-MAY-95',1))
    ERROR at line 1:
    ORA-00947: not enough values

    In this ORA-00947 case, you need to keep in mind that your parenthesis need to be meticulously placed and counted in order for ORA-00947 to be resolved.
