SQL还是捷径？

Question

SELECT * FROM nobel
WHERE winner = 'Theodore Roosevelt' or winner = 'Woodrow Wilson' or winner = 'Jed Bartlet' or winner = 'Jimmy Carter';

有没有办法缩短这个？也许是一种使用正则表达式的方法？

Answer 1

您想要 in运算符(operator):

SELECT n.*
FROM nobel n
WHERE n.winner IN ('Theodore Roosevelt', 'Woodrow Wilson', 'Jed Bartlet', 'Jimmy Carter');
