SQL Code Help... Making it harder than needs to be
I have a table that has multiple rows with the same value in column 'x' with 'x' being the name of an item in this case. So 'x' might have 4 or 5 rows with 'y' and 'z' containing different data. Column 'z' is a true/false column and 'y' has different traits about 'x'. I want to have it so that when I select 'x' it only appears in the output when every 'x' row has a 'z' value of 'True'.
I know that the above is verbose. I'll paste what I have below with comments...
SELECT dbo.Drink.Title, dbo.Ingredient.Title AS Ingredient, dbo.Component.NumUnitsMin, dbo.Unit.UnitName, dbo.Ingredient.IsInMyBar
FROM dbo.Drink INNER JOIN
dbo.Component ON dbo.Drink.DrinkID = dbo.Component.DrinkID INNER JOIN
dbo.Ingredient ON dbo.Component.IngredID = dbo.Ingredient.IngredID INNER JOIN
dbo.Unit ON dbo.Component.UnitID = dbo.Unit.UnitID
WHERE IsInMyBar = 'True' //Trying to limit but oviously this is wrong. For every 'x' there should be no 'x' returned while 'z' = 'true'
Thanks, I've played for hours trying to write a proper where clause.

Heh... great post... I'll bet the new guy is really impressed... much better than posting a solution
Brux...
Here's one way... you'll need to ****************-horn the "test" table into a CTE... I can't do that because I don't have 2005 to test with...
Code:
SELECT t.*
FROM yourtable t,
(
SELECT X,COUNT(*) AS FullCount
FROM yourtable
GROUP BY X
) fc
,
(
SELECT X,COUNT(*) AS TrueCount
FROM yourtable
WHERE Z='T'
GROUP BY X
) tc
WHERE t.x = fc.x
AND t.x = tc.x
AND fc.FullCount = tc.TrueCount
Of course, you'll need to modify the code with the correct column names and table names...
I remember replying to his other post in SQL forum. Infact there he mentioned that he is not known how to move this post, thats why this reply. I think he will be really impressed as you said.

Sorry I was out of town for the last few days. Thanks for the replies. Sorry about the cross-post. I'll give the syntax a try tonight when I settle in for the evening.
As far as being impressed... Anybody who can give advice, on things I don't know, impresses me. I came here to learn, and I did.
