Question

这已被问过好几次并且已经被多次回答，但这是不同的，因为 1）这是在Oracle 11g中 - 我见过的其他示例是在带有StUFF功能的SQL Server中 2）这需要连接2个表来获取信息

让我解释一下

这是包含字段名称和表格的表格。 FILE_ID

CREATE TABLE RESPONSE_METADATA
(
  FILE_ID        NUMBER(10)                     NOT NULL,
  FIELD_NUMBER   NUMBER(4)                      NOT NULL,
  FIELD_NAME     VARCHAR2(50 BYTE)              NOT NULL,
  FIELD_TYPE     VARCHAR2(50 BYTE)              NOT NULL
);

这是一个保存每个文件记录的表，但记录是分开的。

CREATE TABLE RESPONSE_DETAILS
(
  FILE_ID        NUMBER(10),
  REC_FLD_1      VARCHAR2(300 BYTE),
  REC_FLD_2      VARCHAR2(300 BYTE),
  REC_FLD_3      VARCHAR2(300 BYTE),
  REC_FLD_4      VARCHAR2(300 BYTE),
  REC_FLD_5      VARCHAR2(300 BYTE),
  REC_FLD_6      VARCHAR2(300 BYTE),
  REC_FLD_7      VARCHAR2(300 BYTE),
  REC_FLD_8      VARCHAR2(300 BYTE),
  REC_FLD_9      VARCHAR2(300 BYTE),
  REC_FLD_10     VARCHAR2(300 BYTE),
  REC_FLD_11     VARCHAR2(300 BYTE),
  REC_FLD_12     VARCHAR2(300 BYTE),
  REC_FLD_13     VARCHAR2(300 BYTE),
  REC_FLD_14     VARCHAR2(300 BYTE),
  REC_FLD_15     VARCHAR2(300 BYTE),
  REC_FLD_16     VARCHAR2(300 BYTE),
  REC_FLD_17     VARCHAR2(300 BYTE),
  REC_FLD_18     VARCHAR2(300 BYTE),
  REC_FLD_19     VARCHAR2(300 BYTE),
  REC_FLD_20     VARCHAR2(300 BYTE)
);

它需要工作的方式是METADATA表中的每个File_ID都有FIELD_NUMBER。这些Filed_Numbers是Details表中的列

我已经尝试在Oracle中使用XML PIVOT，因为这些列将创建多个节点，因此无法正常工作。

香港专业教育学院曾尝试过透视 - 不起作用。这需要动态 - 但File_ID可以有不超过30个字段。

这需要是存储过程或查询 - 因为我没有构建ETL的权限。

非常感谢你对此的帮助。

Answer 1

尝试生成一个脚本：

select 'select '||FILE_ID||' FILE_ID,'||
  ltrim(sys_connect_by_path('REC_FLD_'||FIELD_NUMBER||' "'||FIELD_NAME||'"',','),',')||
  ' from RESPONSE_DETAILS where FILE_ID=' ||FILE_ID||';'
  from (select t.*,count(*) over (partition by FILE_ID) cnt from RESPONSE_METADATA t)
 where cnt=FIELD_NUMBER start with FIELD_NUMBER=1 
connect by prior FILE_ID=FILE_ID and prior FIELD_NUMBER=FIELD_NUMBER-1

添加了双引号，因为某些列名称保留为“DESC”，例如

将行转换为Oracle列
