Hi Matthew,

Is it working without the quotes “ / "  ?   (I see you are using 2 types of 
quotes, weird)
I guess that’s not needed, and probably causing troubles.   I don’t have to use 
quotes anyway.

Alternatively check the types of data in those 2 tables (if the field types are 
not the same in both tables, the join will not work).

Good luck,
  Constantin

Subject: Inner Join not returning any results in Phoenix

Hi guys,

I’m a little bit stuck with doing an Inner Join with Phoenix. I set up one 
environment, created tables in HBase, and then created views (rather than 
tables) in Phoenix, and am able to query as expected (when I join my two tables 
I see results). I’ve just promoted to another environment, with the exact same 
setup, but my Inner Join returns no results!

I run the following two individual queries:

SELECT * FROM "mytable1" hc
where hc."myId" = 'XS0'

SELECT * FROM "mytable2" bs
where bs."myId" = 'XS0'

And both of these queries give results. But when I run:

SELECT * FROM "mytable1" hc
INNER JOIN “mytable2” bs
On hc."myId" = bs.”myId”

I get no results. I also get no results if I try:

SELECT * FROM "mytable1" hc
where hc."myId" in (select distinct “myId” from “mytable2”)

I have checked in HBase shell and can see the “myId” value is as expected (XS0 
in both tables). I am not sure if there are any logs that I can look at to get 
some insight?

Many thanks in advance for any suggestions!

Cheers,
Matt

PS Something that may or may not be of note: In the environments I am using:
WORKING: hbase-0.98.8-hadoop2 / phoenix-4.2.2-server.jar
FAILING:     hbase-0.98.9-hadoop2 / phoenix-4.2.2-server.jar
