Question

我需要一种方法，可以将2 SA输入的输入与1 SA输出结合起来。

例如

我正在尝试从两个输入读取数据并希望将它们放在一个输出中（SQL表）获得异常说“不允许重复输出名称”

SELECT
    Input.internal.data.id AS id,
    Input.context.data.eventtime AS eventtime,
    recordProperty.PropertyName AS name,
    Cast(recordProperty.PropertyValue.Value AS bigint) AS value
INTO
    [output-custommetric]
FROM
    [input-custommetric] AS Input TIMESTAMP BY Input.context.data.eventtime 
    CROSS APPLY GetElements(Input.[context].[custom].[metrics]) AS flat
    CROSS APPLY GetRecordProperties(Flat.ArrayValue) AS recordProperty

SELECT
    Input.internal.data.id AS id,
    Input.context.data.eventtime AS eventtime,
    recordProperty.PropertyName AS name,
    Cast(recordProperty.PropertyValue.Value AS bigint) AS value
INTO
    [output-custommetric]
FROM
    [input-slacustommetric] AS Input TIMESTAMP BY Input.context.data.eventtime 
    CROSS APPLY GetElements(Input.[context].[custom].[metrics]) AS flat
    CROSS APPLY GetRecordProperties(Flat.ArrayValue) AS recordProperty

由于两个查询的数据类型似乎相同，因此您可以使用UNION将两个查询的输出合并为一个，然后输出到SQL表中。

以下是您的查询的重写：

SELECT
    Input.internal.data.id AS id,
    Input.context.data.eventtime AS eventtime,
    recordProperty.PropertyName AS name,
    Cast(recordProperty.PropertyValue.Value AS bigint) AS value
INTO
    [output-custommetric]
FROM
    [input-custommetric] AS Input TIMESTAMP BY Input.context.data.eventtime 
    CROSS APPLY GetElements(Input.[context].[custom].[metrics]) AS flat
    CROSS APPLY GetRecordProperties(Flat.ArrayValue) AS recordProperty
UNION
SELECT
    Input.internal.data.id AS id,
    Input.context.data.eventtime AS eventtime,
    recordProperty.PropertyName AS name,
    Cast(recordProperty.PropertyValue.Value AS bigint) AS value
FROM
    [input-slacustommetric] AS Input TIMESTAMP BY Input.context.data.eventtime 
    CROSS APPLY GetElements(Input.[context].[custom].[metrics]) AS flat
    CROSS APPLY GetRecordProperties(Flat.ArrayValue) AS recordProperty
