Hi,
I have three tables t1(a, b, c, d), t2(a, b, c, k), and t3(c, e). I need to
outer join them as shown below, but only have all tuples from t1 as output.
But the following syntax does not allow me to do so.
SELECT t1
Hi,
I have three tables t1(a, b, c, d), t2(a, b, c, k), and t3(c, e). I need to
outer join them as shown below, but only have all tuples from t1 as output.
But the following syntax does not allow me to do so.
SELECT t1.*
FROM (t1 outer join t2 on (t1.a=t2.a and t1.b=t2.b)) t outer join t3 on
