.net - Update 2 Table Values In One Query In LINQ?
Apr 26, 2010I have 2 tables Table1 with columns [BId,Name,Amount] Table2 with columns [CId,BId, ExpenseType,Expense]. BId Is the foreign key in Table2. The Amount field in Table1 is always higher than Expense in Table2. I need to update the values of Amount (increase or decrease) based on value of Expense and I want to do it in single query in LINQ. Eg If the Expense has to be updated with 200, I would decrease(negate) Amount value with 200. If Expense is reduce to 100 then the Amount is increased by a value of 100.
View 1 RepliesQuery Table Retrieve Filtered Values?
May 24, 2011I am trying to Query a table with data from another table and return a filtered result
Dim i As Integer = 0
For Each lrow In dtlist.Rows()
Dim lat As Double = dtlist.Rows(i)("Latitude") 'CDbl(Me.SubjLat_txt.Text)
Dim lon As Double = dtlist.Rows(i)("Longitude") 'CDbl(Me.SubjLon_txt.Text)
[code]....
Obviously doesnt work but the idea is thats the Value i need to put in the Value Column of dtlist In short the project, loops through one table(dtlist) of address's and gets the distances of it from the address's in the second table(dtsold) then gets the higest value from dtsold within a certain distance?

View 1 RepliesFilter Parent / Child Table In Linq Query Based On Entities In Child Table?
Jul 9, 2010I have a table (Projects) which is linked to projectVersions on projectID..projectVersions contains several columns on which I'd like to filter a returned project (and associated projectVersions) list. For example there is a "capacity" column and a "country" column. I am doing a filtered list of projects on one page and I'd like to include all projects where any one of the associated projectVersions has a capacity of 750ml and a country of "France" for example.It may be that a particular parameter is not set and so I pass a zero to indicate not to filter on that.I guess this needs some kind of subquery as when I try and do something like this: [code] it doesn't work as the "xxx" bit, being one-to-many, expects me to specify an item to get at the entities within and yet I want to query where ANY of the associated versions match one of the criteria.
View 1 RepliesTake Values From One Table, Based Off The Values In Another?
Apr 9, 2012[code]If I wanted to get Part Name for multiple PartIDs from OrderDetails, how would I go about doing this? Would I use two DataTables? I'm confused as I cannot see an efficient way to do this. The only thing that I can think of is to create a DataTable with SQL:[code]and then maybe use a For loop to take each PartID, create another DataTable to find the PartName for that and then give this to a variable. There could be up to 10 PartIDs to search through and I don't want to have variables such as PartID1 PartID2 etc. [code]
