模糊查询:

@Select({    "SELECT * FROM account where account like CONCAT('%',#{query},'%') or email like CONCAT('%',#{query},'%')"})Account findAccountByAccountOrMail(@Param("query") String query);

批量添加:

@Insert({    "<script>" +        "INSERT INTO company_label(company_id,label_id) values " +        " <foreach collection=/"item/" item=/"item/" index=/"index/" separator=/",/" > " +        "    (#{companyId},#{item}) " +        "  </foreach>" +        "</script>"})void insertLabelForCompany(@Param("companyId") Long companyId,@Param("item") List<Long> item);

批量删除:

@Delete({    "<script>delete from company_label where company_id = #{companyId} and label_id in " +        "<foreach collection = /"item/" item = /"item/" open=/"(/" separator=/",/" close=/")/">" +        "#{item}" +        "</foreach>" +        "</script>"})void removeLabelForCompany(@Param("companyId") Long companyId,@Param("item") List<Long> item);

批量修改:

@Update(value = "<script>" + "update banner b set b.display = #{status} where b.id in "+    "<foreach item = 'item' index = 'index' collection = 'ids' open = '(' separator = ',' close = ')'>#{item}</foreach>" +    "" +    "</script>")int updateStatus(@Param("status") Long status, @Param("ids") Long[] ids);

批量查询:

@Select({    "<script>" +        "select * from product where id in" +        "<foreach item = 'item' index = 'index' collection = 'idList' open = '(' separator = ',' close = ')'>#{item}</foreach>" +        "</script>"})List<Product> findByIdList(@Param("idList")List<Long> idList);

条件查询,if里面不仅可以判空,还可以判断是否满足某个条件

@Select({      "<script>SELECT * FROM company where 1=1 and parent_id = #{companyId} " +          //平级          "<if test = /"isScanSameLevelValue == 1/">and type = #{type}</if>" +           "<if test = /"isScanSameLevelValue == 0/">and type != #{type}</if>" +          "</script> "  })  List<Company> findCompanyConditional(@Param("isScanSameLevelValue") String isScanSameLevelValue, @Param("isScanParentLevelValue") String isScanParentLevelValue, @Param("companyId") Long companyId, @Param("type") Integer type);

条件查询:

 */@Lang(XMLLanguageDriver.class)@Select({"<script>select DISTINCT p.* FROM `us_product`.`hot_category_surgery` hcs "+    "LEFT JOIN `us_product`.`product` p ON hcs.`product_id` =p.`id`"+    "LEFT JOIN `us_product`.`category_surgery` cs on cs.`product_id` =p.`id`"+    "LEFT JOIN `us_product`.`merchant_product` mp on mp.`product_id` = p.`id`"+    "LEFT JOIN `us_product`.`org_product` op on op.`product_id` =p.`id`"+    "where p.`type` =1 and p.`is_for_sale` =1 "+    "        <if test=/"hId != null/"> and hcs.hot_category_id = #{hId} and p.id = hcs.product_id</if>" + //热门类目id    "        <if test=/"categoryId != null/"> and cs.category_id = #{categoryId} and p.id = cs.product_id</if>" + //类目id    "        <if test=/"input != null/">    and (p.name like CONCAT('%',#{input},'%') or p.company like CONCAT('%',#{input},'%')) </if> "+  //用户输入,包括商品名和店铺名,模糊    "        <if test = /" location != null/"> and p.location like CONCAT('%',#{location},'%') </if> "+    //位置..    "        <if test=/"method != null/">   and mp.filter_id = #{method} and p.id = mp.product_id</if> "+  //筛选条件  手术方式    "        <if test=/"org != null/">     and op.filter_id = #{org} and p.id = op.product_id</if> "+   //筛选条件  所属机构    "         ORDER BY sale_volume DESC"+    "        </script>"})List<Product> findProductFromLocal(@Param("hId")Long hId,@Param("categoryId")Long categoryId,@Param("input")String input,@Param("method")Long method,@Param("org")Long org,@Param("location")String location);
