使用mybatis框架在写sql的时候碰到一个异常:
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 ‘)‘ at line 1
类似于sql这样出现的异常
SELECT * FROM eval_question WHERE id not in()
后来就查询前先判断前台传入集合如果长度小于0就不走下面的操作。就不会异常了。
<select id="NotInByEvalQuestion" resultType="com.rm.eval.entity.EvalQnQuestion"> SELECT * FROM eval_question WHERE 1=1 <if test="null != strlist and strlist.size > 0"> and id not in <foreach collection="strlist" index="index" item="item" open="(" separator="," close=")"> #{item} </foreach> </if> </select>
相当于
SELECT * FROM eval_question WHERE id not in("")或者
SELECT * FROM eval_question WHERE 1=1
