如何以表格格式调用我的输出以便我可以查询它？

Question

格式化的代码集以表格格式为我提供输出。 我需要想出一种方法来命名这组代码，就像我们命名一个表一样。

我需要在另一个表中插入我的输出值。

这似乎是一项简单的任务，但我不知道如何插入名称。

 exec sp_xml_preparedocument @xmlhandle output, @Data1, @Data2

我尝试使用此 ^ 调用程序，但仅执行此语句并没有给我输出。

这就是程序的样子。

declare @Data1 xml, @Data2 xml

select @Data1 = 
(
    select * 
    from (select * from Test1 except select * from Test2) as a
    for xml raw('Data')
)

select @Data2 = 
(
    select * 
    from (select * from Test2 except select * from Test1) as a
    for xml raw('Data')
)

;with CTE1 as (
    select
        T.C.value('../@ID', 'bigint') as ID,
        T.C.value('local-name(.)', 'nvarchar(128)') as Name,
        T.C.value('.', 'nvarchar(max)') as Value
    from @Data1.nodes('Data/@*') as T(C)    
), CTE2 as (
    select
        T.C.value('../@ID', 'bigint') as ID,
        T.C.value('local-name(.)', 'nvarchar(128)') as Name,
        T.C.value('.', 'nvarchar(max)') as Value
    from @Data2.nodes('Data/@*') as T(C)     
)
select
    isnull(C1.ID, C2.ID) as ID, isnull(C1.Name, C2.Name) as Name, C1.Value as Value1, C2.Value as Value2
from CTE1 as C1
    full outer join CTE2 as C2 on C2.ID = C1.ID and C2.Name = C1.Name
where
not
(
    C1.Value is null and C2.Value is null or
    C1.Value is not null and C2.Value is not null and C1.Value = C2.Value
)

P.S 如果我不能很好地解释这个问题，我很抱歉。我仍在学习。

您似乎是在说您的代码工作正常，您在 SSMS 中运行存储过程并在网格中生成您想要的结果。您只是希望它进入现有表而不是 SSMS 结果网格

这可能就像在 CTE 和 SELECT 之间添加 INSERT INTO table 一样简单：

with CTE1 as (
    select
        T.C.value('../@ID', 'bigint') as ID,
        T.C.value('local-name(.)', 'nvarchar(128)') as Name,
        T.C.value('.', 'nvarchar(max)') as Value
    from @Data1.nodes('Data/@*') as T(C)    
), CTE2 as (
    select
        T.C.value('../@ID', 'bigint') as ID,
        T.C.value('local-name(.)', 'nvarchar(128)') as Name,
        T.C.value('.', 'nvarchar(max)') as Value
    from @Data2.nodes('Data/@*') as T(C)     
)

INSERT INTO table

select
    isnull(C1.ID, C2.ID) as ID, isnull(C1.Name, C2.Name) as Name, C1.Value as Value1, C2.Value as Value2
from CTE1 as C1
    full outer join CTE2 as C2 on C2.ID = C1.ID and C2.Name = C1.Name
where
not
(
    C1.Value is null and C2.Value is null or
    C1.Value is not null and C2.Value is not null and C1.Value = C2.Value
)

如果查询没有输出一组与表中的列相同的列，则命名要插入的列：

INSERT INTO table (theId, theName, theValue1, theValue2)

无论如何，明确表示可能是个好主意，因为如果将来有人向您的表中添加一列，它肯定会破坏您的过程。如果您明确指出它可能仍然会破坏的列，但不是确定它只会在有人添加“NOT NULL”的列并且他们没有指定列默认值是什么时才会破坏
