Re: Help With Aggragate MAX

if you really want to do it that way you can do

SELECT TOP 1 MAX(value) as MyValue, UTCDateTime
FROM TableName
GROUP BY UTCDateTime

you have to have the top 1 otherwise you will get all of the max values for every dateTime, in descending order..

Please remember to rate helpful or unhelpful answers, it lets us and people reading the forums know if our answers are any good.

This seems to work....I jusk stumbling around until this happened.....

SELECT ActualValue, UTCDateTime
FROM dbo.tblActualValueFloat
WHERE (ActualValue = (SELECT MAX(ActualValue) AS Expr1
FROM dbo.tblActualValueFloat AS tblActualValueFloat_1
WHERE (PointSliceID = '782') AND (UTCDateTime - 0.167 > '5/1/2008')
AND (UTCDateTime - 0.167 < '6 / 1 / 2008'))) AND (PointSliceID = '782')
AND (UTCDateTime - 0.167 > '5 / 1 / 2008') AND (UTCDateTime - 0.167 < '6 / 1 / 2008')

I know there are some hard coded test variables but this seems to be working for now.
Thanks to all

Please help me with the below sql query

I am having 4 tables

I think he wanted to ask the compatibility level(SQL 7.0/2000/2005 etc).

Here's the GUI process:
In the management studio, right click on the db -> select Properties -> click on Options -> the Compatibility Level is displayed along with the collation and recovery model.

But I dont know how to retrieve it using T-SQL.

Hi,

You would need something like this:

CREATE TRIGGER Duplicate ON TableName
AFTER INSERT AS
	INSERT INTO AnotherTable (Column1, Column2...) SELECT Column1, Column2... FROM inserted
END

Oi,

Eu já fiz algumas bases de dados e nunca precisei á data, de usar triggers (em sql).
Mas queres inserir dados ao mesmo tempo em duas tabelas? Porque não fazes isso com uma store procedure normal, achas que não dá para isso?!
O que tens na ideia? talvez te possa ajudar. Cool | :cool:

We need to know what the data looks like in your file and exactly what you want when you are done with your query. It sounds like you do not have much experience with SQL so I'd suggest taking a look at some of these sites to get some basic knowledge:

Another IN clause Question

I'm having some issues with a Query I'm trying to use to fine similar records in a master table. There are several child tables that will be searched in a similar way. Basically, if there are more than two matches in the sub query I want to display those records.
Can anyone point me in the right direction to get this query to work? I understand why I can't use more than one field in my subquery but I can't think of another way to do this.

SELECT *
FROM   UC
WHERE uc_key IN (SELECT mo_Key, COUNT(mo_key) as KeyCount 
		 FROM MO  
		 WHERE (mo_MoKey = @Key1 AND mo_Value = @Value1) OR (mo_MoKey = @Key2 AND mo_Value = @Value2) <- there will be a variable number of these that get generated programatically
                    AND KeyCount > 2)

(note, the table names have been mangled to protect the innocent)

Thanks, any ideas are appreciated.

You probably still want a JOIN; avoid using IN for anything other than literal lists.

I can imagine. Your first task should be to eliminate the subqueries; they don't benefit from indices.

I had to change some of my JOINs the other day because the statements seemed to just sit there, now they zip along.
