我希望用户在2表中获取添加记录的计数。例如,我有一个用户列表(表STF),想知道用户创建了多少产品(在表PV1中)以及他销售了多少产品(在表dpq中),我想显示如下数据:
我有这两个查询,并且不知道如何在一个包含3列的表中显示它们...
查询1:
composer update
查询2:
select staff_username, COUNT(*) as 'count 1'
from STF right join PV1 on STF.staff_username = PV1.admit_user
group by staff_username, staff_name + ' ' + staff_family

我想你想要合并两个表count
,你可以join
并添加count
但是你给我们的信息较少,所以我不确定。
SELECT
STF.staff_username,
STF.Data_in_PV1,
dpq.Data_in_dpq
FROM
(
SELECT
staff_username,
COUNT(PV1.admit_user) AS 'Data_in_PV1'
FROM
STF
RIGHT JOIN
PV1
ON
STF.staff_username = PV1.admit_user
GROUP BY
staff_username
) STF
INNER JOIN
(
SELECT
dpq.trf_staff_id,
COUNT(trf_staff_id) AS 'Data_in_dpq'
FROM
dpq
INNER JOIN
stf
ON
dpq.trf_staff_id = stf.staff_username
GROUP BY
dpq.trf_staff_id
) dpq ON dpq.trf_staff_id = STF.staff_username

您可以尝试加入两个这样的查询。从您提供的有限信息来看,似乎staff_username与trf_staff_id相同,因为您在第二个查询的连接条件中使用了它。
SELECT
staff_username,
count_1,
count_2 FROM
(
SELECT
staff_username,
COUNT(*) AS count_1
FROM
STF
RIGHT JOIN
PV1
ON
STF.staff_username = PV1.admit_user
GROUP BY
staff_username,
staff_name + ' ' + staff_family ) QRY_CNT_1 INNEER JOIN
(
SELECT
trf_staff_id,
COUNT(trf_staff_id) AS count_2
FROM
dpq
JOIN
stf
ON
trf_staff_id = stf.staff_username
GROUP BY
trf_staff_id ) QRY_CNT_2 ON
QRY_CNT_2.trf_staff_id = QRY_CNT_1.staff_username
