PostgreSQL LIMIT


LIMIT 子句

LIMIT 子句用于限制返回的记录的最大数量。

示例

customers 表中返回前 20 条记录

SELECT * FROM customers
LIMIT 20;
运行示例 »

OFFSET 子句

OFFSET 子句用于指定从哪里开始选择要返回的记录。

如果要返回 20 条记录,但从第 40 条开始,可以使用 LIMITOFFSET

注意:第一条记录的编号是 0,因此当指定 OFFSET 40 时,表示从第 41 条记录开始。

示例

返回 20 条记录,从第 41 条记录开始

SELECT * FROM customers
LIMIT 20 OFFSET 40;
运行示例 »
