Retrieving Data from database within the last 7 days using linq
13,737
Solution 1
You can use DateTime.Now.AddDays(-7)
to get the record seven day older then current date. Or you can use Datime.Today.AddDays(-7) if you want the time part and start from after 12 PM.
var query = (from bwl in mg.BarcodeWithLocation
where(bwl.ReceivedDate > DateTime.Now.AddDays(-7))
select new
{
RequestID = bwl.RequestID,
Barcode = bwl.Barcode,
adrid = bwl.AdrID,
name = bwl.Name,
street = bwl.Street,
houseno = bwl.HouseNo,
postal = bwl.Postal,
city = bwl.City,
country = bwl.Country,
latitudetxt = bwl.Latitude == "" ? "Location Unknown" : "View Map Location",
latitude = bwl.Latitude,
longitude = bwl.Longitude,
date = bwl.ReceivedDate
});
Solution 2
Try this:
var dt = DateTime.Now.AddDays(-7);
var query = (from bwl in mg.BarcodeWithLocation
where bwl.ReceivedDate > dt
select new
{
RequestID = bwl.RequestID,
Barcode = bwl.Barcode,
adrid = bwl.AdrID,
name = bwl.Name,
street = bwl.Street,
houseno = bwl.HouseNo,
postal = bwl.Postal,
city = bwl.City,
country = bwl.Country,
latitudetxt = bwl.Latitude == "" ? "Location Unknown" : "View Map Location",
latitude = bwl.Latitude,
longitude = bwl.Longitude,
date = bwl.ReceivedDate
});

I have a
view
with data and I need to retrieve data only from the last 7 days. I know there is a function for this if I was using sql query. but I'm using Linq.here is my code:
try { var query = (from bwl in mg.BarcodeWithLocation select new { RequestID = bwl.RequestID, Barcode = bwl.Barcode, adrid = bwl.AdrID, name = bwl.Name, street = bwl.Street, houseno = bwl.HouseNo, postal = bwl.Postal, city = bwl.City, country = bwl.Country, latitudetxt = bwl.Latitude == "" ? "Location Unknown" : "View Map Location", latitude = bwl.Latitude, longitude = bwl.Longitude, date = bwl.ReceivedDate }); this.Grid.DataSource = query; this.Grid.DataBind(); } catch (Exception exception) { Console.WriteLine("ERROR in GetNoLocationScan() method. Error Message : " + exception.Message); }
can anyone tell me how I do this in Linq ?

Uriil over 11 yearsI think you can't use DateTime.Now.AddDays(-1) inside LINQ to Entity

Paolo Moretti over 11 yearsOr
DateTime.Today.AddDays(-7)
, if you don't want to filter by time
