I am finishing up the development of a web site in ASP.NET with VB.NET and MS SQL Server 2005 on MS Visual Web Developer.  I have a query which pulls the record for a specified product from the table, returning the description field (varchar(6000)).  On my web page, I want to display just the first 100 characters of the description, followed by an elipse (...).  I'm out of time on this project so would like some help, please.
Dim myConn2 As New SqlConnection(ConfigurationManager.ConnectionStrings("omahavaccineConnectionString").ToString)
        myCmd2.Connection = myConn2
        myCmd2.CommandType = CommandType.Text
        myCmd2.CommandText = "Select * from Product where sku='" & strSKU & "' "
        myConn2.Open()
        Dim myReader2 As SqlDataReader = myCmd2.ExecuteReader()
        Do While myReader2.Read
            lblshort_description = (TRIM(myReader2("description")),100) & " ..."
        Loop
        myConn2.Close()

you could do this on the database level
SELECT *, CASE 
	WHEN LEN([Description]) <=100 THEN [Description]
	ELSE SUBSTRING([Description], 1,100) + '(...)'
END AS ShortDescription FROM Product where ...

Ooh, I like that better than what I was thinking.  Why return all that extraneous text when I only need about 100 characters?!?  I'll give that a try!
