Hi Mike,
But does the position of (+) make any difference in the query?
That is, how the query:
SELECT E.FIRST_NAME, A.STATE
differs from the query:
SELECT E.FIRST_NAME, A.STATE
Thanks,
FROM EMPLOYEES E, ADDRESS A
WHERE E.LAST_NAME LIKE 'j%'
AND E.ADDRESS_ID (+) =A.ADDRESS_ID
FROM EMPLOYEES E, ADDRESS A
WHERE E.LAST_NAME LIKE 'j%'
AND E.ADDRESS_ID =A.ADDRESS_ID (+)
