MySQL的返回表名

Question

比方說，我有這個mysql table structure：

table : articles 
---------------- 
id 
content 

table : news 
------------ 
id 
news 

有沒有辦法來搜索這兩個表一個字符串，然後如果發生字符串返回表的名稱和行號？

Answer 1

假設兩個表有ID和新聞/內容相同的數據類型，然後沿

SELECT id, 'articles' as tablename 
WHERE content like '%string to search for%' 
UNION 
SELECT id, 'news' as tablename 
WHERE news like '%string to search for%' 

線路查詢應該給你，你以後

Answer 2

你可以試試這個結果：

SELECT 'articles' as table_name, id 
FROM `articles` 
WHERE content like '%<my_string>%' 

UNION 

SELECT 'news' as table_name, id 
FROM `news` 
WHERE news like '%<my_string>%' 

Answer 3

SELECT * FROM (

SELECT id, content as text, 'articles' as tablename 
FROM articles 

UNION ALL 

SELECT id, news as text, 'news' as tablename 
FROM news 

) as tmp 

WHERE text = 'SEARCH_TERM'
