Thanks, Manish!
So I tried to put the preprocess forwarding into CoalesceFunctionNode,
and that works too. It also looks more in line with the
present design, so I have proceeded with that solution.
This patch
- adds a preprocess method to CoalesceFunctionNode to override the one
in ValueNode, thus making sure the arguments get handled.
- adds a printSubNodes method to CoalesceFunctionNode (was missing
too, I discovered, when I was trying to look at the parse tree after
binding).
- adds a new test case to coalesceTests.java and an updated master
I have run derbyall without errors and also run the modified test to verify
that
it exposes the problem in absence of the fix. The patch is ready for review.

> The following statements generate a NullPointerException:
> CREATE TABLE t1 (i INTEGER);
> CREATE TABLE t2 (i INTEGER);
> UPDATE t1
> SET i = COALESCE(
> (SELECT i FROM t2 WHERE t2.i=t1.i),
> 0);
> Any further SQL statements generate an internal error in RawStore, e.g.:
> SELECT * FROM t1;
