mysql any和all的用法

 

1.ANY關鍵字
假設any內部的查詢語句返回的結果個數是三個，如:result1,result2,result3,那么，

select ...from ... where a > any(...);

->

select ...from ... where a > result1 or a > result2 or a > result3;

2.ALL關鍵字
ALL關鍵字與any關鍵字類似，只不過上面的or改成and。即:

select ...from ... where a > all(...);

->

select ...from ... where a > result1 and a > result2 and a > result3;

3.SOME關鍵字
some關鍵字和any關鍵字是一樣的功能。所以:

select ...from ... where a > some(...);

->

select ...from ... where a > result1 or a > result2 or a > result3;
