As stated in the headline, I want to categorize the results of a join between two tables (target and transaction) based on a number of their columns, then add the values of the columns in BOTH tables. The ensuing query restricts access to columns from the join's FIRST table only!... var actualsVsTargets = (from target in ObjectContext.PipelineTarge...
In linq-to-sql, you can really perform the following to come pretty close:...from a in MyTable
where a.classID == 5
group a by 0 into g
select new
{
Sumfld1 = g.Sum(x => x.fld1),
Sumfld2 = g.Sum(x => x.fld2),
Sumfld3 = g.Sum(x => x.fld3)
}
...(Observe the cluster by ...0...)...It cannot be converted into a sql....GROUP BY...
, but a..
The three columns in my table are ID, ShortCode, and UploadDate....I want to use LINQ to arrange those groups and produce a list after grouping the results by shortcode (while keeping all the results)....I have these things:... rawData.Provider.CreateQuery<PDFDocument>(qb.rootExperession)
.ToList<PDFDocument>().
GroupBy(b=>b.ShortCode)
.SelectMany(...
By using a new anon class, you can group as follows:...// I created a Foo class to show this working
var fooList = new List<Foo> {
new Foo { ItemId = 62224, Code = "NC0860000", StatusId = 8 },
new Foo { ItemId = 62225, Code = "NC0860000", StatusId = 8 },
new Foo { ItemId = 62226, Code = "NC0860000", StatusId = 8 },
new Foo { ItemId ...
I think you've found what you're searching for...GroupBy...
clause....var list = dbConnection.Form_Datas
.Join(dbConnection.Forms, fd => fd.form_ID, f => f.form_ID,
(fd, f) => new { form_data = fd, form = f })
.Where(a => a.form_data.External_ID == personID)
.GroupBy(s => new
{
FormID = s.form.form_ID,
FormN...
This is a follow-up to a query that Jon Skeet previously responded to, which you may ...locate here....The intended outcome is as follows:...A 100
A 80
B 80
B 50
B 40
C 70
C 30
...if you have the following class:...public class Student
{
public string Name { get; set; }
public int Grade { get; set; }
}
...With Jon Skeet's response, it is p...
