1、批量删除
Mapper.java
public void deleteCommunityRelUser(@Param("communityId") String communityId,@Param("userIdList") List<String> userIdList) throws Exception;
sql.xml
<delete id="deleteCommunityRelUser"> DELETE FROM COMMUNITY_REL_USER <where> <if test="communityId != null and communityId != ''"> AND COMMUNITY_ID=#{communityId} </if> <if test="userIdList != null and userIdList != ''"> AND USER_ID IN <foreach item="item" collection="userIdList" separator="," open="(" close=")" index=""> #{item} </foreach> </if> </where> </delete>
2、批量修改
Mapper.java
public void updateCommunityRelUser(@Param("communityId") String communityId,@Param("userIdList") List<String> userIdList) throws Exception;
sql.xml
<update id="updateCommunityRelUser"> UPDATE COMMUNITY_REL_USER SET AUDIT='1' <where> <if test="communityId != null and communityId != ''"> AND COMMUNITY_ID=#{communityId} </if> <if test="userIdList != null and userIdList != ''"> AND USER_ID IN <foreach item="item" collection="userIdList" separator="," open="(" close=")" index=""> #{item} </foreach> </if> </where> </update>
3、批量新增
Mapper.java
public void insertInviteUser(@Param("communityMemberVOList") List<CommunityMemberVO> communityMemberVOList) throws Exception;
sql.xml
mysql
<insert id="insertInviteUser" parameterType="java.util.List"> INSERT INTO COMMUNITY_REL_USER (USER_ID,COMMUNITY_ID,AUDIT) VALUES <foreach item="item" collection="communityMemberVOList" separator="," index="index"> (#{item.userId:VARCHAR},#{item.communityId:VARCHAR},#{item.audit:VARCHAR}) </foreach> </insert>
oracle
<insert id="insertInviteUser" parameterType="java.util.List"> INSERT INTO COMMUNITY_REL_USER (USER_ID,COMMUNITY_ID,AUDIT,create_date) <foreach item="item" open="(" close=")" collection="communityMemberVOList" index="index" separator="union all"> select #{item.userId,jdbcType=VARCHAR}, #{item.communityId,jdbcType=VARCHAR}, #{item.audit,jdbcType=VARCHAR}, #{item.createdate:TIMESTAMP} from dual </foreach> </insert>
