join type or sub query join

So I have a query that is checking for the count of the items of a certain type with in a certain area of the warehouse.  What I now have to check is where we are selling the items -- one of the warehouse managers want to see if there is discontinued stock still out there.

So the two tables that have data on selling the item are cET and cETd, the cET table tells me where the item is selling (field name = SELLING) and the cETd table tells me whether the item is out on the floor (field name = AVAIL).  What I was going to use to join the tables is the sku number (field name = SKU) is in the myplay table and that links to the cET field by the same name and that gets you the field name SELLING.  The cET is linked to cETd by the fielld name cET_id and that gets you the field name AVAIL.

What I am having problems with is doing the join to check for both conditions.  Can someone help?
select tc, jhgh06, COUNT(*) AS OccNum
from db45.myplay
group by tc, jhgh06
Order by tc, jhgh06

i hope i understood you
are you looking for something like:

select tc, jhqh06, count(*) as OccNum
from db45.myplay t1 join cet t2 on t1.sku = t2.sku
  join cetd t3 on t2.cet_id = t3.cet_id
group by tc, jhqh06
order by tc, jhqh06

Then would I put in a where clause to say where SELLING = '0' and AVAIL = '0'?

Are you sure you want "= 0" (equals 0) instead of "<> 0" (not equals 0)?

So you want to list the COUNT(*) only from rows that have no SELLING and no AVAIL?

I now have to check ... where we are selling the items...

If SELLING = '0', isn't that a row indicating NOT SELLING? I suspect that I'm not understanding the design of this database.

If COUNT(*)>0 for rows where AVAIL=0, is that an indication that the item is at the location but not "out on the floor", e.g., in storage?

Ugh you are correct.  *hangs head in shame*  Not sure why that only dawned on me now.

No problem. I just wanted to be sure the direction was right.
