Using aliases-declarations in sql, PL-SQL Programming

Assignment Help:

Using Aliases

The Select-list items fetched from a cursor related with the %ROWTYPE should have simple names or, if they are expressions, should have aliases. In the example below, you use an alias known as the wages:

-- available online in file ’examp4’
DECLARE
CURSOR my_cursor IS
SELECT sal + NVL(comm, 0) wages, ename FROM emp;
my_rec my_cursor%ROWTYPE;
BEGIN
OPEN my_cursor;
LOOP
FETCH my_cursor INTO my_rec;
EXIT WHEN my_cursor%NOTFOUND;
IF my_rec.wages > 2000 THEN
INSERT INTO temp VALUES (NULL, my_rec.wages, my_rec.ename);
END IF;
END LOOP;
CLOSE my_cursor;
END;
