Question

我需要尋找一列的字符串，對相同字符串的變化多次搜索與MySQL LIKE miltiple倍，所以我這樣做

SELECT * 
FROM `users` 
WHERE user = 'king' 
OR alias = 'king' 
OR aliases LIKE '%,king%' 
OR aliases LIKE '%king,%' 
OR aliases LIKE '%king,%' 

列aliases將包含逗號分隔的單詞例如king,queen,knight等 但是因爲像本身很慢，我想知道是否有什麼辦法可以優化這個查詢

Answer 1

試試這個：

SELECT * 
FROM `users` 
WHERE user = 'king' 
OR alias = 'king' 
OR FIND_IN_SET ('king', aliases)>0;
