> {noformat}
> explain

> FROM myinput1 a LEFT OUTER JOIN myinput1 b on a.value = b.value  RIGHT OUTER

> Pushing the first condition to the first join, triggers a merge of the 2 
> QBJoinTrees. During merge all the right side  filters identified for pushing 
> are assumed to refer to the merging table (b in this case). But the pushable 
> filters can refer to any left table.
