MySQL的合并多个表中的一个视图

Question

我有，我希望能够在一个视图结合3个表：

tblContent: 
strTitle  | txtContent 
content 1 title | content 1 content 
content 2 title | content 2 content 
content 3 title | content 3 content 

tblNews 
news_title  | news_content 
news 1 title | news 1 content 
news 2 title | news 2 content 

tblTradeMembers 
company_title | company_content 
trade 1 title | trade 1 content 
trade 2 title | trade 2 content 
trade 3 title | trade 3 content 
trade 4 title | trade 4 content 

所以基本上，我想每个表中的内容映射到我的单

title   | content    | from 
content 1 title | content 1 content | tblContent 
content 2 title | content 2 content | tblContent 
content 3 title | content 3 content | tblContent 
news 1 title | news 1 content  | tblNews 
news 2 title | news 2 content  | tblNews 
trade 1 title | trade 1 content  | tblTradeMembers 
trade 2 title | trade 2 content  | tblTradeMembers 
trade 3 title | trade 3 content  | tblTradeMembers 
trade 4 title | trade 4 content  | tblTradeMembers 

所以我可以做：

select * from custom_view WHERE content LIKE "%3%" 

这是交流，我感到那么可以查询，这将是像结果视图可以治疗，我该怎么做？

Answer 1

试试这个

SELECT strTitle AS 'TITLE', txtContent AS 'Content', 'tblContent' AS 'From' 
UNION  
SELECT news_title AS 'TITLE', news_content AS 'Content', 'tblNews' AS 'From' 
UNION 
SELECT company_title AS 'TITLE', company_content AS 'Content', 'tblTradeMembers' AS 'From' 

这将俱乐部在视图中的所有记录
