--This is the hidden INNER JOIN Code
--that will only get me those stores that owe Royalties. Unless all stores in Florida owe,
--then there will be missing records.
Select t1.StoreID, t1.StoreName, t1.GeneralManager, t1.EstablishDate, t3.RoyaltiesDue
from StoreInfo t1
LEFT OUTER JOIN FranchiseDetails t3
on t1.StoreID = t3.StoreID
where t1.StoreState = ‘FL’ and t3.RoyaltiesDue > 0.00;
--Code that will get me all stores in Florida and then print RoyaltiesDue for ONLY
--the stores that owe Royalties
Select t1.StoreID, t1.StoreName, t1.GeneralManager, t1.EstablishDate, t3.RoyaltiesDue
from StoreInfo t1
LEFT OUTER JOIN FranchiseDetails t3
on t1.StoreID = t3.StoreID
and t3.RoyaltiesDue > 0.00
where t1.StoreState = ‘FL’;
Does that make sense to you?
This was perfect Brandie, I was approaching it from the complete inverse situation, where moving my criterion into the JOIN still exploded my resultset, instead of limiting it, but was NOT what I wanted. Apologies for no data, lunch is over, gotta get back to the nosy grindstone...sample of what I mean:
--left join with the argument in the WHERE
SELECT DISTINCT am2.memid,am2.ratecode
FROM dbo.vwActiveMembers AS am2
LEFT JOIN dbo.capterm AS c2 ON am2.ratecode = c2.ratecode
WHERE am2.fullname LIKE 'a%'
AND c2.ratecode='C600A25'--278 rows
ORDER BY am2.memid,am2.ratecode--,c2.capamount
go
--left join with the argument in the JOIN
SELECT DISTINCT am2.memid,am2.ratecode
FROM dbo.vwActiveMembers AS am2
LEFT JOIN dbo.capterm AS c2 ON am2.ratecode = c2.ratecode
AND c2.ratecode='C600A25'
WHERE am2.fullname LIKE 'a%'--10,334 rows
-- essentially returns all values from vwActiveMembers and
-- only returns values from capterm where the ratecode='C600A25'
ORDER BY am2.memid,am2.ratecode--,c2.capamount
go Your example made me consider it from a different angle (as far as when you would WANT to do this), and I think I have a handle on it now...although I'll still go check out that other thread, definitely. ;-):-D

BUSHY PLANS!! Thank you, Paul. Time to give that another read.

Isn't associative memory wonderful?
Stick or branch join...bushy plans...funny!

Jon,Where you place the criteria for OUTER JOIN's DOES make a difference. Whenever you place criteria in the WHERE clause that references a column in your OUTER table SQL Server will convert that JOIN to an INNER JOIN. This is because of when the criteria is evaluated. I don't have the order of evaluation memorized but it does make a difference. Itzik covers this in one of his books, I think it is Professional T-SQL Programming, but not sure.
Itzik also had a great tips and tricks session where he showed order of JOIN criteria can make a difference as well.
I didn't follow this the first time I read it, but I do now. Thanks Jack!

/* Give me all persons their relationship and the typenote the second join is INNER and the ON for it is defined first and the
ON Clause for the LEFT JOIN is defined second which means
SQL Server does the INNER JOIN first and then the OUTER JOIN
on that Virtual Table */
SELECT
*
FROM
#persons AS P LEFT JOIN
#relationships AS R JOIN
#relationship_types AS RT
ON R.relationship_type_id = RT.relationship_type_Id
ON P.person_id = R.person_id;
That is sick and twisted stuff....I like it!

The more I thought about the clock and metric time, the more confused I got.
Defining a day, hours, and minutes - not so bad.
But then I started thinking there are 10 days in a week, 10 weeks in a month, and 10 months in a year.
At this point, my head started to hurt.
And then there suddenly is some technical discussion happening.
I just hope when we go metric with time, that I only work 5 days a week, and 4 weeks a month.
And can live with the fact that I will short change them by 2 months a year.

Both should do it. I could use some reading on the subject :w00t::w00t:

With this, would day and night be on a rotating schedule? Some days at 2pm it would be night and some days it would be day?

Hey, we wouldn't age as far because our birthdays would only come every 1000 days instead of every 365 days. 😛
(10 day/week x 10 week/month x 10 month = 1000 days)

Thus the new 40 will be 20. I don't know if I want to fell 40 when I am twenty - that's just not right.

No, that's a metric calendar and you're not going to get that until you live in space. Since we still have to deal with the vagarities of Earth's orbit our best bet with the calendar is the 13 month calendar with 7 days a week and 4 weeks a month.
Once you live in space, feel free to jump to the metric calendar! You'll get to make all kinds of new names up for the days and months. Maybe even the weeks if you're feeling creative!

I was banking on the day being the same length. I could live easier with the seasons being messed up than not having a clue that in several weeks what I thought would be the middle of the day is the middle of the night.
I think the space I will live in won't be outer space, but a nice padded room.

Off the technical and metric time topic (I love non-metric cause I'm an American :-D). Just had my PASS NomCom interview. Hard to tell how it went because it's on the phone so you don't get feedback you get in person.
