Question

Trying to use records with the cursor and later index by table in the mix.

DECLARE CURSOR emp_cur IS
    SELECT employee_id, first_name||' '|| last_name "name"
    FROM employees 
    ORDER BY salary desc;

emp_rec emp_cur%ROWTYPE;

BEGIN 
    FOR emp_rec IN emp_cur
    LOOP
        DBMS_OUTPUT.PUT_LINE('Employee ID:'||emp_rec.employee_id||CHR(10)||
                             'Employee Name:'||emp_rec.name);
        EXIT WHEN emp_cur%ROWCOUNT = 10;
    END LOOP;
END;

When I run above code I get

 ERROR at line 13, "NAME" must be declared.

How can I access the column first_name||’ ‘||last_name inside the For loop? or do I just have to do traditional OPEN, simple loop, FETCH and close?

Answer 1

You’re very close; the problem is just that identifiers that are not in double-quotes get converted to uppercase, while identifiers that are in double-quotes do not. So name, NAME, and "NAME" are equivalent to each other, and all of them are different from "name". Either change this:

first_name||' '|| last_name "name"

to this:

first_name||' '|| last_name name

or else, if you prefer, change this:

'Employee Name:'||emp_rec.name

to this:

'Employee Name:'||emp_rec."name"
