Hi,

I am use the phoenix to do the follow union all query:

select distinct t1.IDNO from (select IDNO from LOC_TRAVEL union all select IDNO from LOC_HOTEL) t1 join (select IDNO from LOC_TRAVEL union all select IDNO from LOC_HOTEL) t2 on t1.IDNO = t2.IDNO;

but some error was reported:
Error: Encountered exception in sub plan [0] execution. (state=,code=0)
java.sql.SQLException: Encountered exception in sub plan [0] execution.

if I change the first union all statement as some other query statement, for example:

select distinct t1.IDNO from (select IDNO from LOC_TRAVEL) t1 join (select IDNO from LOC_TRAVEL union all select IDNO from LOC_HOTEL) t2 on t1.IDNO = t2.IDNO;

it can work. 

I don't know why phoenix take the union all operator as a table in the first statement? are there some limits in Phoenix sql.

Please help me about this, it's an urgent issue to .

 

thanks a lot!
