Now... here is the problem I am having... the above SQL query is
retrieving results from one table: sales
I have another table called customers with a couple of fields
(customerid, and customername are two of the fields).
I want to join on the customerid in both tables to retrieve the
customername in the query.
So I need the results to look something like this:
customerid | customername |
TODAYS_USERS | LAST 7 DAYS | LAST 30 DAYS
bigint | varchar |
bigint | bigint
| bigint

8699 | Joe Smith | 1

1 | 1
8700 | Sara Olson | 1
| 12
| 17
8701 | Mike Jones | 3

5 | 19
Can someone show me how to use a JOIN with the above SQL Statement? I
need to bring the customername field into the query from the other
table and I have been having issues writting the query... can this
even be done?
something like...
SELECT results.customerid, c.customername, count(distinct count1) AS
"TODAYS_USERS",
count(distinct count2) AS "LAST 7 DAYS" ,
count(distinct count3) AS "LAST 30 DAYS"
FROM (SELECT distinct case when s.modified >= '2010-02-11' then
s.modelnumber else null end as count1,
case when s.modified >= '2010-02-04' then s.modelnumber else null
end as count2,
case when s.modified >= '2010-01-11' then s.modelnumber else null
end as count3, s.customerid
FROM sales as s WHERE s.modelnumber LIKE 'GH77%') AS results
JOIN customers as c ON (results.customerid = c.customerid)
GROUP BY results.customerid
