我有两个实体,一个团队和一个雇员。
我想获取一份急切的团队员工清单。该列表必须进行分页。
public PagedList<Employee> GetAllEmployeesWithEagerLoadedTeams(int page, int pageSize)
{
var criteria = GetSession()
.CreateCriteria(typeof (Employee))
.SetFetchMode(DomainModelHelper.GetAssociationEntityNameAsPlural(typeof (Team)),FetchMode.Eager);
var totalCount = criteria
.SetProjection(Projections.RowCount())
.FutureValue<Int32>().Value;
return criteria
.SetFirstResult(page * pageSize)
.SetMaxResults(pageSize)
.Future<Employee>()
.ToPagedList(page, pageSize, totalCount);
}
为什么这不起作用?
SQL结果:
SELECT count(*) as y0_ FROM [Employee] this_;
SELECT TOP 10 y0_ FROM (SELECT count(*) as y0_,
ROW_NUMBER() OVER(ORDER BY CURRENT_TIMESTAMP) as __hibernate_sort_row FROM [Employee] this_) as query WHERE query.__hibernate_sort_row > 10 ORDER BY query.__hibernate_sort_row;
解决方案
您正在尝试重复使用已经指定的计数投影和未来值的标准变量。您需要为第二个查询创建新标准。
