SELECT column_name(s)
FROM table_name
LIMIT number

FROM Persons
LIMIT 5

---

Oracle 语法

SELECT column_name(s)
FROM table_name
WHERE ROWNUM <= number

例子

SELECT *
FROM Persons
WHERE ROWNUM <= 5

SELECT *
FROM (select rownum as r,directory,content from sql) tab
WHERE tab.r>ceil(sum/pagesize)*(page-1) and tab.r<=ceil(sum/pagesize)*(page-1)
sum--总条数
pagesize--一页多少条
page--第几页
