Mapper文件SQL语句SELECT报错
问题描述:
在查询用户信息时,用了下面的语句,但是一直报错,没找到是因为什么。
<select id="findOneByCondition" resultMap="RM_SpUser">
SELECT
<include refid="columns" />
FROM sp_user
<include refid="findOneByCondition_where" />
LIMIT 0,1
</select>
另外选择语句为:
<!-- 查询条件 -->
<sql id="findOneByCondition_where">
<where>
<if test ="userId !=null and userId != ''">and userId = #{userId}</if>
<if test ="phone !=null and phone !=''">and phone = #{phone}</if>
<if test ="token !=null and token !=''">and token = #{token}</if>
<if test ="password !=null and password !=''">and password = #{password}</if>
<if test ="status !=null and status != ''">and status = #{status}</if>
<if test ="name !=null and name != ''">and name = #{name}</if>
<if test ="sex !=null and null !=''">and sex = #{sex}</if>
<if test ="headImageUrl !=null and headImageUrl != ''">and headImageUrl = #{headImageUrl}</if>
<if test ="orderCount !=null and orderCount != ''">and orderCount = #{orderCount}</if>
<if test ="note !=null and note != ''">and note = #{note}</if>
<if test ="createTime !=null and createTime != ''">and createTime = #{createTime}</if>
<if test ="updateTime !=null and updateTime != ''">and updateTime = #{updateTime}</if>
</where>
</sql>
答
这个查询出来的会是一个list吧 把resultMap 改为resultType 后面为对应的model类 试试
答
SELECT * FROM sp_user LIMIT 0,1 少个*?
答
没有全部显示出来,在条件和判断语句时用的都是
SELECT
FROM sp_user
LIMIT 0,1
