How do I add a where filter using the original Linq-to-SQL object in the following scenario
- by GenericTypeTea
I am performing a select query using the following Linq expression:
Table<Tbl_Movement> movements = context.Tbl_Movement;
var query = from m in movements
select new MovementSummary
{
Id = m.DocketId,
Created = m.DateTimeStamp,
CreatedBy = m.Tbl_User.FullName,
DocketNumber = m.DocketNumber,
DocketTypeDescription = m.Ref_DocketType.DocketType,
DocketTypeId = m.DocketTypeId,
Site = new Site()
{
Id = m.Tbl_Site.SiteId,
FirstLine = m.Tbl_Site.FirstLine,
Postcode = m.Tbl_Site.Postcode,
SiteName = m.Tbl_Site.SiteName,
TownCity = m.Tbl_Site.TownCity,
Brewery = new Brewery()
{
Id = m.Tbl_Site.Ref_Brewery.BreweryId,
BreweryName = m.Tbl_Site.Ref_Brewery.BreweryName
},
Region = new Region()
{
Description = m.Tbl_Site.Ref_Region.Description,
Id = m.Tbl_Site.Ref_Region.RegionId
}
}
};
I am also passing in an IFilter class into the method where this select is performed.
public interface IJobFilter
{
int? PersonId { get; set; }
int? RegionId { get; set; }
int? SiteId { get; set; }
int? AssetId { get; set; }
}
How do I add these where parameters into my SQL expression? Preferably I'd like this done in another method as the filtering will be re-used across multiple repositories.
Unfortunately when I do query.Where it has become an IQueryable<MovementSummary>. I'm assuming it has become this as I'm returning an IEnumerable<MovementSummary>. I've only just started learning LINQ, so be gentle.
