Hello,

I Want to make a query that is selecting the date part from a datetime field in sql server 2008 db, and order the query on
the date field the query selected.
I have the following query that selects the datetime field,
(underlined). I want to chanche that by selecting the date part from that field.

 SELECT     TOP (100) PERCENT dbo.Orders.Klantnummer, (dbo.Orders.Orderdatum) AS Date, dbo.Orderdetail.Verkoopprijs, dbo.Orderdetail.Tal, 
                      SUM(dbo.Orderdetail.Verkoopprijs * dbo.Orderdetail.Tal) AS Expr1, dbo.Orders.Store, dbo.Orders.IsBetaald
FROM         dbo.Orders INNER JOIN
                      dbo.Orderdetail ON dbo.Orders.Orderid = dbo.Orderdetail.OrderId
GROUP BY dbo.Orders.Klantnummer, (dbo.Orders.Orderdatum) , dbo.Orderdetail.Verkoopprijs, dbo.Orderdetail.Tal, dbo.Orders.Store, dbo.Orders.IsBetaald
HAVING      (dbo.Orderdetail.Tal <> 0) AND (dbo.Orders.Store IS NULL) AND (dbo.Orders.IsBetaald <> 3)
ORDER BY (dbo.Orders.Orderdatum) DESC

Can someone help?

Txs,

John

make it DATEADD(dd,DATEDIFF(dd,0,dbo.Orders.Orderdatum),0)

Ihave used the syntaxis in my query ; this query filters the date from the datetime field (yyyy-mm-dd 00:00:00.000)

ViewInkPermndLing

[CODE]

SELECT TOP (100) PERCENT dbo.Orders.Klantnummer, DATEADD(dd, DATEDIFF(dd, 0, dbo.Orders.Orderdatum), 0) AS Datum, dbo.Orderdetail.Verkoopprijs, dbo.Orderdetail.Tal,
SUM(dbo.Orderdetail.Verkoopprijs * dbo.Orderdetail.Tal) AS Expr1, dbo.Orders.Store, dbo.Orders.IsBetaald
FROM dbo.Orders INNER JOIN
dbo.Orderdetail ON dbo.Orders.Orderid = dbo.Orderdetail.OrderId
GROUP BY dbo.Orders.Klantnummer, DATEADD(dd, DATEDIFF(dd, 0, dbo.Orders.Orderdatum), 0), dbo.Orderdetail.Verkoopprijs, dbo.Orderdetail.Tal, dbo.Orders.Store,
dbo.Orders.IsBetaald
HAVING (dbo.Orderdetail.Tal <> 0) AND (dbo.Orders.Store IS NULL) AND (dbo.Orders.IsBetaald <> 3)
ORDER BY Datum DESC

[/CODE]

From that query I take the sum:

ViewInkPermndLing1
[CODE]
SELECT Datum, SUM(Expr1) AS Som, Klantnummer
FROM dbo.ViewInkPermndLin
GROUP BY Datum, Klantnummer
HAVING (Klantnummer <> 1869) AND (Klantnummer <> 1847) AND (SUM(Expr1) > 0)
[/CODE]
And I want to have the sum of the previous query order by month and year:

ViewTotalMonth
[CODE]
Transform Sum(Som) As SomofSom
SELECT format(Datum, mmm) AS Month, Month(Datum) AS Expr 1
FROM dbo.ViewInkPermndLing1
GROUP BY Format(Datum, mmm), Month(Datum)
Order By Month(Datum), Year (Datum)
[/CODE]

How do I do this?

Txs,

John

[code]
SELECT Month(Datum), Year (Datum),Sum(Som) As SomofSom
FROM dbo.ViewInkPermndLing1
GROUP BY Month(Datum), Year (Datum)
Order By Month(Datum), Year (Datum)
[/code]

Txs,

Is there also a way to put the results in a way like in access (a crosstabel query?)

month Year2010 Year2011 Year2012
01 2314 3214 3421
02 3212 5462 4352

and so on...

John

you can
see


SELECT     Month(Datum), 
SUM(CASE WHEN Year(Datum) = 2010 THEN Som END) As [Year2010],
SUM(CASE WHEN Year(Datum) = 2011 THEN Som END) As [Year2011],
SUM(CASE WHEN Year(Datum) = 2012 THEN Som END) As [Year2012]
FROM         dbo.ViewInkPermndLing1
GROUP BY Month(Datum)
Order By Month(Datum)

Txs,

it works great.
But I have a few questions:
1. Does it mean I have to update the view each year?
2. What with null values in the query (or view)?
Because I use the view to fill a datagridview where I calculate
the sum. And with Null values this gives an error.

Is there a way to fill in an integer (0 value as integer) so the calcultion in vb.net can take place?

Txs,
John

you can make it dynamic
see
http://beyondrelational.com/modules/2/blogs/70/posts/10840/dynamic-pivot-in-sql-server-2005.aspx

2. What with null values in the query (or view)?

its just a warning
you can disable it by setting ANSI_WARNINGS OFF

Is there a way to fill in an integer (0 value as integer) so the calcultion in vb.net can take place?
you mean replace NULL with 0?
yes its possible using ISNULL or COALESCE()

Txs,
John
