我有一个linq语句,它应该生成一个通用的左外部连接(特别是使用空值),但它却生成了一个奇怪的sql,它也使用count(*)(from ccc in cDataContext.CategoryCountryCategoryTypeMappings[CategoryCountryCategoryTypeMappings] AS [t0]我要
这是我的sql查询:SELECT ParkingPlaceName, NoOfParkingPlaces, COUNT(Place.ParkingAreaID) AS NoOfCarsParked, NoOfParkingPlaces-COUNT(Place.ParkingAreaID) FROM ParkingArea LEFTJOIN Place ON ParkingArea.ParkingAreaID = Place.ParkingAreaIDLEFTJOIN Car ON
我试图在linq中写一个查询,我连接了3个表,并用字符串"ANY“填充了空值,但这并没有发生,需要一些帮助,我是新手。我试着做这样的事情... join building in allbuildings where building.buildingidallbuildings{BuildingName="ANY" BuildingID=0})

请指导如何在linq中编写以下sql查询 Item.Id AS ItemId, Item.CatId, [Case].Id AS CaseId LEFT OUTER JOIN [Case] WITH (NOLOCK) ON [Case].Id = Item.CaseId
LEFT OUTERJOIN [Cust] WITH (NOLOCK)
