I have a string of hex characters "0x89504e". I convert this to a string of binary characters @sOutput = "100010010101000001001110". I then run SELECT CAST(@sOutput AS BINARY). This returns me "0x313030303130303130313031303030303031303031313130000000000000".

How would I go about converting the string to binary such that the value would return as the original "0x89504e"? It's looking like the CAST is treating the string as numeric and converting a really large int to binary.

It is treating the string as a string and converting it in to its ASCII codes.

I don't use binary data types much, but the following works:

DECLARE @hex AS VARBINARY(10)
SET @hex = 0x89504e
SELECT @hex

NOTE: There are no quotes/apostrophes around the hex value.

If you are coming from an application, use varbinary parameters and pass the value to the paramter as a byte array (byte[])

Hi all,

I have a function called fnGetOrderItemPriceDummy, which takes two parameters, such as @OrderID & @chord. I was trying to execute this function in our linked server, and it fired error. My code follows.....

(Select * from Openquery([linkedserver],'select myserver.dbo.fnGetOrderItemPriceDummy ( '+ Convert(varchar(50) ,@OrderID)+' , '''''+ @chord+'''''))

.

Can anyone say where is my mistake....

Thanks for your time.....

Sebastian

I don't know syntax of OPENQUERY command, but I am sure that you are missing a database name here:

select myserver.DATABASE.dbo.fnGetOrderItemPriceDummy

I have these tables

Customer Table:
CustomerID int; PK
FirstName nvarchar;
LastNaem nvarchar;
etc.;

Products Table:
ProductID int; PK
Name varcahr;
etc.;

OrderItems Table:
OrderItemID int; PK
ProductID int; FK
CustomerID int; FK
etc.;

Now I would like to get all users that have ordered: Product1 AND Product2, etc.
Only those people that orders all the selected products

Pass @Products --> with comma separated values like 'product1,product2'
and no of items @ProductCount --> 2

Select * from Customers Where CustomerID in
(Select CustomerID From
(Select CustomerID from OrderItems Inner Join Products on Products .ProductID = OrderItems.productid
Where [Name] IN (@products)
Group by CustomerID,[Name]) as Temp
Group by CustomerID having Count(CustomerID) = @productCount)

This can't possibly work, can it?

I mean, the WHERE [Name] IN (@Products) part specifically.

If this has to work then the query should get execute using "EXEC sp_executesql" command

You could create the inner query like this:

SELECT oi.CustomerID
FROM OrderItems oi
	JOIN Products p
WHERE p.ProductID IN ('Product1', 'Product2')
GROUP BY oi.CustomerID
HAVING COUNT(*) = 2

You'll have to dynamically create the WHERE p.ProductID IN (...) part, and the value for the HAVING COUNT(*) = 2 should use a parameter.

Joined with the customer table, the results could look something like this:

DECLARE @NumberOfProducts int
SET @NumberOfProducts = 2

SELECT
	c.*
FROM Customer c
	JOIN
	(
		SELECT oi.CustomerID
		FROM OrderItems oi
			JOIN Products p
		WHERE p.ProductID IN ('Product1', 'Product2')
		GROUP BY oi.CustomerID
		HAVING COUNT(*) = @NumberOfProducts
	) AS t
		ON t.CustomerID = c.CustomerID

sqlclient uses a an ole connection and you can use to connect it to SQL Server, this is the prefered method and is used in most examples.

dear friends,

I develop an Win application by using MS Access.I have got a problem in SQL statement.I have got a form that has

got 2 ComboBox and a DataGridView.The name of the first is cmbCategories and the second one is cmbContent.Content

is listing the content of categories.I use an array to transfer letters when I choose the category in

cmbCategories as it is Alphabetical Array.When I choose a letter from cmbContent like A,B or another one,but no

records is listing in the DataGridView.I try to use "Like" statement for this action.It is like this:

string strSQL = "select FilmName from films where FilmName like" + "'" + cmbContent.Text + "*'";

cmbContent has got the Alphabetical letters by sequence.I want to list the FilmName that is beginning as

alphabetic.For example,when I choose letter A,the films begins A must be listed.Does anybody help me?Thanks for

your help.

I tried,but it doesnt work.I wrote the whole code below.maybe it helps what I want to do.

private DataView Get_DataAlphabetic()
{
string constr = "Provider=Microsoft.JET.OLEDB.4.0;Data Source=" + Environment.CurrentDirectory + "\\mdb\\film_db.mdb";

OleDbConnection con_ole = new OleDbConnection(constr);

string strSQL = "select FilmName from films where FilmName like " + "'" + cmbContent.Text + "*'";
OleDbDataAdapter da = new OleDbDataAdapter(strSQL, con_ole);
DataTable dt = new DataTable();
da.Fill(dt);
DataView dv = new DataView(dt);
dv.Sort = "FilmName ASC";
da.Dispose();
con_ole.Close();
return dv;
}

I send it to a datagrid's datasource property in another method as I use cmobobox's SelectedIndexChanged method.Hope it is clear.I wait for your replies

Why you aren't trying to use Filter instead of getting directrly from database.

Download all data at first time from database then use filter property.
