添加列結果

Question

以下是我對藝術家表 -

id name sex 
1 harsh male 
2 geet female 

以下是我對事件表 -

id artist_id created_by 
2 2   16 
2 2   17 

以下是我的查詢 -

SELECT * FROM `events` WHERE artist_id IN (SELECT id FROM `artists` WHERE name LIKE '%$search_term%') 

但除了事件數據我需要在結果中獲得藝術家的名字，請讓我知道我需要改變什麼ry，因爲我試過*, artists.name它不會工作。

Answer 1

嘗試此查詢

SELECT e.* 
FROM `artists` AS a 
JOIN `events` AS e ON e.artist_id = a.id 
WHERE a.name LIKE '%$search_term%'; 

Answer 2

你需要從兩個表中同時選擇。使用join爲

SELECT artists.name, events.* 
FROM artists 
INNER JOIN events 
    ON artist.id = artist_id 
WHERE 
    name LIKE '%search_term%' 

Answer 3

使用join代替[子查詢VS加入]的IN

SELECT 
    e.*, 
    artists.name 
FROM 
    `events` e 
    inner join `artists` a on e.artist_id = a.id 
WHERE 
    name LIKE '%$search_term%'
