使用mysql在单个查询中执行多个查询

Question

我有两个查询。一个是总销售额，另一个是净销售额。我想在单个查询中报告。我怎样才能做到这一点？

总售

Location Name          Gsale 
(sub-dealer-temp)         2 
2049 (Sub-Dealer) Always Protected, LLC    3 
2052 (Sub-Dealer) Alert Security, Inc    4 
2055 (Sub-Dealer) Alarm Connection, LLC    5 
2067 (Sub-Dealer-t) Activation Dept, LLC   67 
2068 (Sub-Dealer-t) Premier Security USA, LLC  8 

净卖出

location Name          Nsale 
2055 (Sub-Dealer) Alarm Connection, LLC    5 
2067 (Sub-Dealer-t) Activation Dept, LLC   67 
2068 (Sub-Dealer-t) Premier Security USA, LLC  8 
2783 ((Sub-Dealer-t) Premier abc     45 
2783 ((Sub-Dealer-t) Premier xyz     32 

结果

Lc.Name        Gsale    Nsale 
(sub-dealer-temp)      2    null 
2049 (Sub-Dealer) Always Protected, LLC 3    null 
2052 (Sub-Dealer) Alert Security, Inc 4    null 
2055 (Sub-Dealer) Alarm Connection, LLC 5    5 
2067 (Sub-Dealer-t) Activation Dept, LLC 67    67 
2068 (Sub-Dealer-t) Premier Security US 8    8 
2783 ((Sub-Dealer-t) Premier abc  null    45 
2783 ((Sub-Dealer-t) Premier xyz  null    32 

Answer 1

您可以使用加入或低于联盟是连接查询

 select g.location,g.name,g.Gsale,n.Nsale from gross sale g 
    join net sale n on g.location=n.location 

Answer 2

您可以使用波纹管的SQL代码：

表名1：现在总销售为gross_sale和列名lcName，Gsale

表名2：现在的净销售为net_sale和列名lcName，Nsale

SELECT a.lcName, a.Gsale, b.Nsale FROM gross_sale a 
FULL OUTER JOIN net_sale b ON a.lcName=b.lcName ORDER BY a.lcName;
