[comp.databases] Informix, subquery and outer join

jo@wdl1.UUCP (Jo Mitchell) (04/12/90)

	What happens if you try your query with just two tables - badge
	and timegroup?  I'm tending to think theres some type of restriction
	when using "outer" (there was with Sybases when I used it 6mos 
	ago - something about not allowing it on a table that was
	used in a nested query).

	If you figure it out - post it,ok?

This is not possible, since the heart of the problem is that there are
three tables invovled, with the outer join and subquery on *different*
tables.  Eliminating the third table reduces the example to a subquery,
which works.

Based on a posting from someone at Informix, who said that the examples
I posted produced, when run using the Informix 4.0 release, produced the
results I claimed would be correct, rather than the results I am getting,
this is obviously a bug in the Informix releases I have.
