從兩個不相關的表格一起獲取記錄

-1

我有一個場地和服務表。我想在兩次表格中選擇所有記錄。兩者都有不同的列。從兩個不相關的表格一起獲取記錄

服務表：

Name Type  Collation Attributes Null Default Extra Action 
    1 serviceId Primary int(11)   No None AUTO_INCREMENT Change 
    2 entry_by varchar(255) latin1_swedish_ci  No None   
    3 service_name varchar(255) latin1_swedish_ci  No None   
    4 service_address varchar(255) latin1_swedish_ci  No None   
    5 latitude double   No None  Change Change Drop Drop 
    6 longitude double   No None  Change Change Drop Drop 
    7 servicetypeId int(11)   No None  Change Change Drop 
    8 active int(11)   No None  Change Change Drop Drop

場地表：

1 venueIdPrimary int(11)   No None AUTO_INCREMENT Change 
2 venue_name varchar(255) latin1_swedish_ci  No None  
3 venuetypeId int(11)   No None  Change Change Drop Drop 
4 entry_by varchar(255) latin1_swedish_ci  No None   
5 venue_address varchar(255) latin1_swedish_ci  No None   
6 latitude double   No None  Change Change Drop Drop 
7 longitude double   No None  Change Change Drop Drop 
8 active int(11)

我嘗試此查詢：SELECT服務。 ，場地。 FROM services，venues

但它給出重複記錄。所有記錄3次：

如何從兩個表中獲得唯一記錄？謝謝。

什麼是你想要的表格中顯示的預期結果？ – Drew

在查詢中嘗試使用DISTINCT關鍵字。 – FDavidov

這兩個表都沒有任何關係，使用「select * from table a union select * from table b」 –

嘗試以下操作：

select 
'Services'  as Source  , 
serviceId  as ID   , 
entry_by  as entry_by  , 
service_name as name   , 
service_address as address  , 
latitude  as latitude  , 
longitude  as longitude , 
servicetypeId as typeID  , 
active   as active  
from services 

union 

select 
'Venues'   as Source  , 
venueIdPrimary as ID   , 
entry_by   as entry_by , 
venue_name  as name  , 
venue_address as address  , 
latitude   as latitude , 
longitude  as longitude , 
venuetypeId  as typeID  , 
active   as active  
from venues ;

注意，我添加了一個文本字段，這樣你就會知道其中記錄的來源。
