mybatis 查询
mybatis 查询
查询一段时间内增加的公司:<= 在 xml 中要写成: >=
<select id="findCompanyInfoPage" resultMap="baseMap" parameterType="java.lang.String"> SELECT a.company_name,a.company_address,b.user_telephone,a.create_time,b.user_nick_name FROM trade_company_info a,se_user b,app_crm_rel c WHERE b.sid=c.app_user_id AND c.company_id=a.sid AND b.user_role IN ('2','3') <if test=" startDate != null and startDate != '' "> AND DATE_FORMAT(a.create_time,'%Y-%m-%d') >= #{startDate} </if> <if test=" endTime != null and endTime != '' "> AND DATE_FORMAT(a.create_time,'%Y-%m-%d') <= #{endTime} </if> limit #{start},#{pageSize} </select>
mapper.java 中的方法:
List<Map<String,Object>> findCompanyInfoPage(@Param("startDate")String startDate,@Param("start")int start,@Param("pageSize")int pageSize,@Param("endTime")String endTime);
mybatis xml 中的 等于是 == , sql 是 =
<if test="reqParam.state != null and reqParam.state != '' and reqParam.state == 'REJECTANDNORMAL' "> AND ( a.state = 'REJECT' or a.state = 'NORMAL' ) </if> <if test="reqParam.state != null and reqParam.state != '' and reqParam.state != 'REJECTANDNORMAL' "> AND a.state = #{reqParam.state} </if>
