是否有 ANSI SQL 替代 MYSQL LIMIT 关键字?
Is there an ANSI SQL alternative to the MYSQL LIMIT keyword?
LIMIT 关键字限制 SELECT 返回的行数，例如:
The LIMIT keyword limits the number of rows returned by a SELECT e.g:
SELECT * FROM People WHERE Age > 18 LIMIT 2;
返回 2 行.
SELECT * FROM People WHERE Age > 18 LIMIT 10, 2;
返回前 10 行之后的 2 行.
returns 2 rows after the first 10.
