獲取最新10條記錄的sql語句如下：

select * from some_table order by id desc limit 0,10

SELECT * FROM table LIMIT [offset,] rows | rows OFFSET offset

LIMIT 子句可以被用于強制 SELECT 語句返回指定的記錄數(shù)。MySQL LIMIT 接受一個或兩個數(shù)字參數(shù)。參數(shù)必須是一個整數(shù)常量。如果給定兩個參數(shù)，第一個參數(shù)指定第一個返回記錄行的偏移量，第二個參數(shù)指定返回記錄行的最大數(shù)目。初始記錄行的偏移量是 0(而不是 1)：為了與 PostgreSQL 兼容，MySQL 也支持句法： LIMIT # OFFSET #。

MySQL> SELECT * FROM table LIMIT 5,10;

檢索記錄行 6-15

為了檢索從某一個偏移量到記錄集的結束所有的記錄行，可以指定第二個參數(shù)為 -1：

MySQL> SELECT * FROM table LIMIT 95,-1;

檢索記錄行 96-last.

如果只給定一個參數(shù)，它表示返回最大的記錄行數(shù)目：

MySQL> SELECT * FROM table LIMIT 5;

檢索前 5 個記錄行。換句話說，LIMIT n 等價于 MySQL LIMIT 0,n。

實例如下：

mysql> use sppeivan;
Database changed
mysql> select * from employee; // 返回所有結果
