I have an unexpected issue with a side effects on a table which is ignored
by a recursive query. I've tried to simplify the issue to a simple
example, see the attached sql script.
Version 1 results in:
it / fid / stuff / foo full contents
0 | 0 | | {1:one,2:two}
1 | 1 | one | {1:one,2:*}
2 | 2 | two | {1:*,2:*}
The key issue for me is that table Foo is updated (as shown by the last
column), but although 'two' was updated to '*' by iteration 1, the last
iteration still sees the initial 'two' which does not exist anymore.
Version 2 illustrates more or less the behavior I would have expected.
I've read again Section 7.8 about WITH queries, but I have not seen
anything that would disprove my expectation.
Am I wrong somewhere? Or is this a subtle bug?
