Mybatis条件検索ロット添削検索機能

あいまいなクエリ:

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

一括追加:

@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);

一括削除:

@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);

一括修正:

@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);

一括クエリ:

@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);

条件検索では、ifでは空判定だけでなく、条件を満たしているかどうかを判断することができます。

@Select({
      "<script>SELECT * FROM company where 1=1 and parent_id = #{companyId} " +
          //  
          "<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);

条件クエリー:

    "LEFT JOIN `us_product`.`product` p ON hcs.`product_id` =p.`id`"+
