MySQL行级锁定显示语法错误

Question

我尝试使用MySQL / PHP在我的应用程序中实现行级锁定。

如此http://dev.mysql.com/doc/refman/5.6/en/innodb-lock-modes.html

中所述

但是当我试图执行这些查询时。

SELECT * FROM account WHERE id = 13 LOCK IN SHARE MODE;

SELECT * FROM account WHERE id > 13 FOR UPDATE;

它给了我以下错误：

SELECT * FROM account WHERE id = 13 LOCK IN SHARE MODE
 LIMIT 0, 25 

MySQL said: Documentation
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'LIMIT 0, 25' at line 2 

我使用的是版本mysql 5.6.23。
