使用查詢語句的時候，經常要返回前幾條或者中間某幾行數據，這個時候怎么辦呢？不用擔心，mysql已 經為我們提供了這樣一個功能。

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。LIMIT 接受一個或兩個數字參數。參數必須是一個整數常量。如果給定兩個參數，第一個參數指定第一個返回記錄行的偏移量，第二個參數指定返回記錄行的最大數目。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，它表示返回最大的記錄行數目：?
mysql>?SELECT?*?FROM?table?LIMIT?5;?????//檢索前?5?個記錄行

//換句話說，LIMIT n 等價于 LIMIT?0,n。

實例：

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