Question

有没有办法从OUTPUT子句生成xml，如下所示

DECLARE @Test TABLE (Id int, Name varchar(max))

INSERT @Test 
OUTPUT (SELECT INSERTED.* FOR XML RAW('data'), ELEMENTS XSINIL, TYPE)
VALUES (1, 'One'), (2, 'Two'), (3, 'Three')

UPDATE @Test SET Name = Name
OUTPUT (SELECT DELETED.*, INSERTED.* FOR XML RAW('data'), ELEMENTS XSINIL, TYPE)

DELETE FROM @Test
OUTPUT (SELECT DELETED.* FOR XML RAW('data'), ELEMENTS XSINIL, TYPE)

但是因为此代码失败，“OUTPUT子句中不允许使用子查询。”

谢谢，斯拉瓦

来自MSDN

The OUTPUT clause is not supported in the following statements:
• DML statements that reference local partitioned views, distributed partitioned views, or remote tables.
• INSERT statements that contain an EXECUTE statement.
• Full-text predicates are not allowed in the OUTPUT clause when the database compatibility level is set to 100.
• The OUTPUT INTO clause cannot be used to insert into a view, or rowset function.
• A user-defined function cannot be created if it contains an OUTPUT INTO clause that has a table as its target.

您无法使用output子句生成xml。所以另一种方法是在插入或更新表时将中间表变量声明为目标，然后从中声明SELECT。像这样的东西 -

DECLARE @T TABLE (Id int, Name varchar(max))

INSERT @Test 
OUTPUT INSERTED.*
INTO @T
VALUES (1, 'One'), (2, 'Two'), (3, 'Three')

DELETE FROM @Test
OUTPUT DELETED.*
INTO @T

SELECT *
FROM  @T FOR XML RAW('data'), ELEMENTS XSINIL, TYPE

试试这个：

DECLARE @Test TABLE (Id int, Name varchar(max))
DECLARE @Inserted TABLE (Id int, Name varchar(max))

INSERT @Test 
OUTPUT INSERTED.* INTO @Inserted
VALUES (1, 'One'), (2, 'Two'), (3, 'Three')

SELECT * From @Inserted FOR XML RAW('data'), ELEMENTS XSINIL, TYPE

从output子句生成xml
