如何在不重複「foo」的情況下寫入「WHERE foo ='bar'或foo ='baz'OR ...」

Question

我是MySQL新手，想知道;而不是做

SELECT fields FROM table WHERE name="tim" OR name="bob" OR name="nancy" OR name="john" 

如果我可以做類似

SELECT fields FROM table WHERE (name="tim" OR "bob" OR "nancy" OR "john") 

Answer 1

使用IN條款：

SELECT fields FROM table WHERE name IN ("tim", "bob", "nancy", "john"); 

Answer 2

你可以這樣做 -

SELECT fields FROM table WHERE name in("tim","bob","nancy","john")
