Choose one of two values
Date: Mon, 28 Sep 2009 07:40:31 -0700 (PDT)
I'm running a simple select stmt thus:
select A.value, b.value
from A, B
However, either A.value or B.value is null and I need to select the
non null value.
Is there a way of specifying within pl/sql this construct?
Select ( if (A.value) is null and (B.value) is not null then B.value
else if (B.value) is null and (A.value) is not null then A.value else if (B.value) is not null and (A.value) is not null thenA.value)
From A, B
In the third case above, either is ok so I arbitrarily cose A.value.
Hope this is clean enough.
Thanks in advance,
