    sqlplus matching

    Hi Friends,

    I have table EMP with column empname and another
    LOANS_TABLE with column fullname.

    EMP
    ======
    EMPNAME
    -----------
    TOM WELLING
    SCOTT WILSON


    LOANS_TABLE
    ===========
    FULLNAME
    ------------
    WELLING, TOM

    I want to list/match the employees with loans, eventhough lastname is
    entered first in the loans table. In this case TOM WELLING is same
    as WELLING, TOM

    Can you help me please...

    Thanks a lot

      5        length(y)) || ' ' ||

    Can you say "full table scan baby"? Also, this method has tons of potential for error... As pando says, make your data clean.

    Thanks hun.....but there are still some records that can not be hit...

    I want something that uses the "like" function... as in:

    select x.empname, y.fullname from EMP x, LOANS_TABLE y
    where y.fullname like '%TOM%' and y.fullname like '%WELLING%');

    Can u help me split the empname to be similar to the above form?


    Thanks again
