今天遇到如下问题
Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: 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 6
; bad SQL grammar []; nested exception is com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: 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 6
才知 mybatis 使用了 statementType="STATEMENT" 属性
<select id="getUserReginAllList" parameterType="java.util.Map"
statementType="STATEMENT" resultType="UserReginLogEntity">
select * from userregin${tableTime} where 1=1
<if test="id!=null">
and uid like concat('%','${id}','%')
</if>
<if test="serverId!=-1">
and serverId = ${serverId}
</if>
limit #{skip},#{take}
</select>
如果使用了
statementType="STATEMENT"(非预编译) , #{xxx} 的#就不能用了 需要换成${xxx}
我觉得mybatis传值是map的 在mapper中取值最好用${}
