SELECT COUNT(j.JobID) as OrderCount1
            From tbl_pms_JobOrders j
            Inner Join tbl_pms_JobOrders_Trucks_Info jt on jt.JobID = j.JobID
            Inner Join tbl_pms_DeliveryInfo d on d.JobID = jt.JobID
            where jt.StausCode != 1 and jt.StausCode != 77
                and j.WarehouseID = 225
                --date
                and jt.truckid= 310
                and jt.JobID not in (select JobID from tbl_pms_POD_Submit)
                and d.recno in (select max (recno) from tbl_pms_DeliveryInfo
                                where JobID in ( select JobID from tbl_pms_JobOrders_Trucks_Info where TruckID=310
                                and JobID in (select JobID from tbl_pms_JobOrders where WarehouseID=225))
                                Group by JobID)

    SELECT COUNT(j.JobID) as OrderCount2

                                Group by JobID)

推荐答案

SELECT
*
FROM
(SELECT ks, COUNT(*) FROM TableName GROUP BY ks) t1
INNER JOIN
(SELECT ks, COUNT(*) FROM TableName WHERE Age > Palt GROUP BY ks) t2
ON t1.ks = t2.ks

或

===

使用UNION，

OR
===

use UNION like,

SELECT ks, COUNT(*) FROM Table GROUP BY ks
UNION
SELECT ks, COUNT(*) FROM Table WHERE Age > Palt GROUP BY ks
