[英]Azure Data Factory - SQL
I would like to ask you if is it possible to use "output inserted" SQL statement in data flow (Azure Data Factory)我想问你是否可以在数据流中使用“输出插入”SQL语句(Azure数据工厂)
Currently, I am getting an error:目前,我收到一个错误:
at Source 'source1': shaded.msdataflow.com.microsoft.sqlserver.jdbc.SQLServerException: A nested INSERT, UPDATE, DELETE, or MERGE statement is not allowed in a SELECT statement that is not the immediate source of rows for an INSERT statement.
在源“source1”处:shaded.msdataflow.com.microsoft.sqlserver.jdbc.SQLServerException:SELECT 语句中不允许嵌套的 INSERT、UPDATE、DELETE 或 MERGE 语句,该语句不是 INSERT 语句的直接行源.
What I did:我做了什么:
I also checked stored procedures but they do not provide any output.我还检查了存储过程,但它们不提供任何输出。
What I want:我想要的是:
I would like to get the 'Id' of row of inserted elements (Insert+Select in one operation).我想获得插入元素行的“Id”(在一个操作中插入+选择)。
As error shows, insert statement isn't allowed.如错误所示,不允许插入语句。
As a work around, you can do like this.作为一种解决方法,您可以这样做。
@activity('Lookup1').output.firstRow.ID
@activity('Lookup1').output.firstRow.ID
3.Inside data flow, choose your table as your source and enter this expression: 3.在数据流内部,选择您的表作为源并输入以下表达式:
concat('select ID from dbo.test6 where ID =',toString($ID))
4.If your need to do some transform, you can create a DerivedColumn
and do like this: 4.如果你需要做一些转换,你可以创建一个
DerivedColumn
并这样做:
