XPath Select An Attribute Based On Value?

Mar 26, 2010

Using VB.Net,I have an XmlNode object, xNode.I need to select an attribute of this node if it has a particular value.

e.g. xNode.SelectSingleNode(".[@attr1='1']")

I would expect this statement to return the attribute "attr1", only if it has a value of "1". However, I get an error - Expression must evaluate to a node-set.When I tried this - xNode.SelectSingleNode("@attr1[@attr1='1']")It always returns Nothing, even if the attribute has a value of 1.

Select The Record Based On An Id?

May 8, 2009

I have a table and I need to select the record based on an Id. I only want to return the record that has the Max(Date) on a date field. How do I do that?

In SQL Server I use this

SELECT * FROM dch
WHERE EffectiveDate = (SELECT MAX(EffectiveDate) FROM dch
WHERE ID = 99) AND ID = 99

How can I do this in Linq. Unfortunately this app is coded in VB.NET as we inherited it that way.

I was trying these

Dim qry = (From dch In db.dch _
Where dch.Dealer.Equals(Dealer) _
Select dch.EffectiveDate).Max()

Asp.net - Select Query In LINQ Based On Foreign Table

Mar 2, 2011

I have 2 Tables , OrderDetails and Requests In my LINQ to SQL dbml file. OrderDetailsID is a foreign key in Requests Table.

I want to write the query to get the sum of UnitCost from OrderDetails based on OrderId. And If there is a row in Requests Table for each OrderDetailsID, and the Requests.Last.RequestType="Refund" I want to reduce the total refund amount from the main sum otherwise If there is no row based on OrderDetailsID, add to sum.

Here is the way I implement that. I am looking to prevent using "For each".

iRefund = (From od1 In dc.OrderDetails _
Where od1.OrderID =1 _
Select od1.UnitCost).Sum
