我有一个疑问：
Select p.Name, p.ProductGroupID as GroupID, g.Name as GroupName
FROM Products as p
LEFT JOIN ProductGroups as g
ON p.ProductGroupID = g.ProductGroupID
我可以使用 dbContext.Database.SqlQuery(query) 来获取 ProductView 的列表，其中 ProductView 是
class ProductView
{
string Name;
GroupView Group;
}
class GroupView
{
int id;
string Name;
}
SqlQuery 不支持复杂类型
你应该做的是：
internal class TempResult
{
public string Name { get; set; }
public int? id { get; set; }
public int? AddressId { get; set; }
public string groupName { get; set; }
}
var tempResults = db.Database.SqlQuery<TempResult>(
@"Select p.Name, p.ProductGroupID as GroupID, g.Name as GroupName
FROM Products as p
LEFT JOIN ProductGroups as g
ON p.ProductGroupID = g.ProductGroupID",
objectParameterList.ToArray()).ToList();
querySearchResult = tempResults.Select(t => new SearchResult
{
Name = t.Name,
Group = new GroupView
{
id = t.id,
Name = t.groupName,
}
}
