It is not a real 3 table join. You should use the Table3 5 times in your
join.
You would have something like this
SELECT
A.COL1, U.COLZ ,V.COLZ ,W.COLZ ,X.COLZ ,Y.COLZ
FROM
TABLE1 A, TABLE2 B, TABLE3 U, TABLE3 V, TABLE3 W, TABLE3 X, TABLE3 Y
WHERE A.COL2 = B.COL1, B.COL2 = U.COL1, B.COL3 = V.COL1, B.COL4 = W.COL1,
B.COL5 = X.COL1, , B.COL6 = Y.COL1
