select distinct USERID , PRODUCTID ,ProductName  from tableA inner join tableB on tableA.PRODUCTID  = tableB.ID

for a specific USERID:
select distinct USERID , PRODUCTID ,ProductName  from tableA inner join tableB on tableA.PRODUCTID  = tableB.ID where USERID = theuserid

you can prefix the columns based on which table they came from, i.e.

select TableA.USERID, TableA.PRODUCTID, TableB.ID, TableB.ProductName
from TableA
 inner join TableB on TableA.PRODUCTID = TableB.ID
