我现在有一个类似这样的表：
表1

ID|NAME|INFO_CODE_1|INFO_CODE_2|INFO_CODE_3|INFO_CODE_4|INFO_TEXT|DESCRIPTION
1 |Test|123        |254        |556        |867        |Test Text|Test Description

我试图将表1中的数据插入表2中，这样第一个表中的每条记录都会变成第二个表中的四条独立记录，如下所示：
表2

ID|NAME|INFO_CODE|INFO_TEXT|DESCRIPTION
1 |Test|123      |Test Text|Test Description
1 |Test|254      |Test Text|Test Description
1 |Test|556      |Test Text|Test Description
1 |Test|867      |Test Text|Test Description

表\u 1中有成千上万条记录，还有其他列的数据我们不关心，而info\u code \u 1到info\u code \u 4中的值都因记录而异（甚至可能为空）。我在考虑写这样的东西：

INSERT OVERWRITE TABLE example.TABLE_2
SELECT
A.ID AS ID,
A.NAME AS NAME,
A.INFO_CODE_1 AS INFO_CODE,
A.INFO_TEXT AS INFO_TEXT,
A.DESCRIPTION AS DESCRIPTION
FROM
example.TABLE_1 A
UNION ALL
SELECT
A.ID AS ID,
A.NAME AS NAME,
A.INFO_CODE_2 AS INFO_CODE,
A.INFO_TEXT AS INFO_TEXT,
A.DESCRIPTION AS DESCRIPTION
FROM
example.TABLE_1 A
UNION ALL
SELECT
A.ID AS ID,
A.NAME AS NAME,
A.INFO_CODE_3 AS INFO_CODE,
A.INFO_TEXT AS INFO_TEXT,
A.DESCRIPTION AS DESCRIPTION
FROM
example.TABLE_1 A
UNION ALL
SELECT
A.ID AS ID,
A.NAME AS NAME,
A.INFO_CODE_4 AS INFO_CODE,
A.INFO_TEXT AS INFO_TEXT,
A.DESCRIPTION AS DESCRIPTION
FROM
example.TABLE_1 A;

这样行吗？
如果是的话，有没有更好的方式写声明？
有没有办法确保具有相同id的所有记录都被依次插入？
提前感谢你们能提供的任何帮助。
