我有一个查询，执行后给我总计12408条记录，但我希望这给我总计记录作为计数列
选择 c.complaint_id，c.server_time，c.completion_date，c.road_id，c.photo，c.dept_code，c.dist_code，c.eng_userid，c.feedback_type，c.status，p.dist_name，p.road_name，p。 road_dept，e.display_name，e.mobile 来自作为c INNER JOIN pwd_roads作为p ON的投诉p.road_id = c.road_id INNER JOIN enc_details为e ON CAST（e.enc_code为INTEGER）= p.enccode 其中c.complaint_id = c.parent_complaint_id和c.dept_code ='PWDBnR' 和c.server_time在“ 2018-09-03”和“ 2018-12-19”之间

最简单但不太优雅的方法是：
select count(*)
from
(
select c.complaint_id,c.server_time,c.completion_date,c.road_id,c.photo,c.dept_code,c.dist_code,c.eng_userid,c.feedback_type,c.status,p.dist_name,p.road_name,p.road_dept,e.display_name,e.mobile from complaints as c INNER JOIN pwd_roads as p ON p.road_id=c.road_id INNER JOIN enc_details as e ON CAST(e.enc_code as INTEGER) = p.enccode where c.complaint_id=c.parent_complaint_id and c.dept_code='PWDBnR' and c.server_time between '2018-09-03' and '2018-12-19'
)

您可以使用窗口功能解决此问题。例如，如果您希望第一列是var ans2 = from w in workspend
where DateTime.Parse("2018-12-28") <= w.Date && w.Date <= DateTime.Parse("2018-12-29")
select new {
w,
(from cs in customers where cs.SearchTerms.LastIndexOf(w.Description.Substring(0, 2)) == cs.SearchTerms.Length - 2 select cs).FirstOrDefault().CustomerNo
};
语句完成的总行数：
SELECT请注意，如果使用window函数，则在使用select count(1) over(range between unbounded preceding and unbounded following) as total_row_count
, c.complaint_id,c.server_time,c.completion_date,c.road_id,c.photo,c.dept_code,c.dist_code,c.eng_userid,c.feedback_type,c.status,p.dist_name,p.road_name,p.road_dept,e.display_name,e.mobile from complaints as c INNER JOIN pwd_roads as p ON p.road_id=c.road_id INNER JOIN enc_details as e ON CAST(e.enc_code as INTEGER) = p.enccode where c.complaint_id=c.parent_complaint_id and c.dept_code='PWDBnR' and c.server_time between '2018-09-03' and '2018-12-19'
子句之前对其进行求值，因此，如果要向查询中添加LIMIT，则即使行数最大，行数也可能大于100将返回100行。
