For all I know, there is the following syntax:
Syntax one: The ON follows the JOIN, from top to bottom
SELECT * ;
FROM Cur1 ;
INNER JOIN Cur2 ;
ON Cur1.Field=Cur2.Field ;
;
INNER JOIN Cur3 ;
ON Cur2.Field=Cur3.Field
Syntax two: The ONs follows the JOINs, inside to outside
SELECT *;
FROM Cur1;
INNER JOIN Cur2;
INNER JOIN Cur3;
ON Cur2.Field=Cur3.Field;
ON Cur1.Field=Cur2.Field
You are free to mix the styles. It might create a headache, but is it possible.
