    Selecting the number of characters from a field?

    Gurus,

    I'm new to SQL and I'm hoping someone can help me. I need to write an SQL statement to give me the number of users with less than 8 characters in the name. Please help!!!

    declare
    v_len number;
    c1_rec c1%ROWTYPE;
    cursor c1 is select username from dba_users;
    begin
    open c1;
    loop;
    fetch c1 into c1_rec;
    exit when c1_rec%NOTFOUND;
    select getlength(c1_rec.username) into v_len from dual;
    if(v_len>8)
    then
    dbms_output.put_line();
    fi;
    end loop;
    close c1;
    end;

    Regards

    I'm sorry to say that, Barun, but your script is nothing but bunch of errors.

    The sql needed might be something like this:
    Code:
    select count(*) from the_table where length(username)<8;

    Wow! Script doesn't even attempt to solve poster's business specifications. Why would you do it simple and well when you can do it complex and all wrong, isn't it?

    Ales is spot on correct.
