我有一个连接其他三个表的表。
表SPP:
+------------+---------------+-------+
| SPP_Code | City | County
+------------+---------------+-------+
表SPB:
+------------+---------------+-------+-------+
| SPB_code | SPP_Code | Name | Add1
+------------+---------------+-------+-------+
表五:
+------------+---------------+-------+
| vw_Code | customer |SPB_code|
+------------+---------------+-------+
表数字:
+------------+---------------+-------+---------+
| Num_Jref | vw_Code | period| Amount
+------------+---------------+-------+---------+
我需要找出SPB_code,姓名,城市,县,ADD1,2015/01年度至2015/03年度之间的总金额
到目前为止我已经完成了这项工作,但不确定如何连接其中两个查询。
查询1:
SELECT spb.SPB_code, spb.Name, spb.ADD1, SUM (num.Amount_1) AS sum_amount_1
FROM SPB spb
INNER JOIN VW vw
ON spb.SPB_Code = vw.SPB_Code
INNER JOIN Num nm
ON vw.Code = nm.CODE
WHERE nm.period >= '201501'
AND nm.period <= '201503'
GROUP BY spb.SPB_code, spb.Name, spb.ADD1 ;
QUERY2:
SELECT DISTINCT spb.SPB_code, spp.SPP_Code, spp.City, spp.County
from SPB spb
JOIN SPP spp
ON spb.SPB_code =spp.SPP_Code
任何帮助将不胜感激。 感谢

如果您只想根据您指定的列找到总金额,则以下查询将有效,

<div id="chart_div"></div>

你必须在其外键上加入所有相关的表格,并将你要查询的所有字段分组,希望这有助于解决你的问题。
SELECT
spb.SPB_Code, spb.Name, spp.City, spp.Country, spb.Add1
FROM
SPB spb
inner join SPP spp on spp.SPP_Code = spb.SPP_Code
inner join VW vw on vw.SPB_Code = spb.SPB_Code
inner join Num num on num.vw_Code = vw.vw_Code
WHERE
num.period >= '201501'
AND
num.period <= '201503'
GROUP BY
spb.SPB_Code, spb.Name, spp.City, spp.Country, spb.Add1
