適用於:SQL Server Azure Data Factory 中的 SSIS Integration RuntimeForeach from Variable 列舉值會透過以變數傳遞給它的清單中之項目來列舉,並針對每個項目執行相同的工作。 您可以在指令碼工作中使用自訂程式碼,針對此目的填入清單。 如需列舉值的詳細資訊,請...
枚举器 = Foreach Azure Blob 枚举器 “Azure Blob 枚举器”允许 SSIS 包在指定的 blob 位置枚举 blob 文件。 枚举的 blob 文件名可以存储在变量中并用于 Foreach 循环容器内的任务。 Azure Blob 枚举器是适用于 Azure for SQL Server 2016 (13.x)的 SQL Server Integration Services (SSIS) 功能包的组件。
In a package, looping is enabled by using a Foreach enumerator. The Foreach Loop container repeats the control flow for each member of a specified enumerator. SQL Server Integration Services provides the following enumerator types: Foreach ADO enumerator to enumerate rows in tables. For example,...
Variables must be added within the SSIS package, and to use them, you must add the @ character as the prefix. As example, if we added the @[User::Counter] variable, to implement a for loop similar to For(int i=0;i<10;i++){},we must use the following expressions: InitExpression...
In this article, I show you how to use the Foreach Loop container to copy files from one folder to another. We will start with a new SSIS package, so you don’t have to try to work with a previous setup. However, before configuring the package, you’ll need a se...
SSIS provides 7 types of enumerators with foreach loop container. Foreach File enumerator to enumerate files in a folder. The enumerator can traverse subfolders. Foreach Item enumerator to enumerate items that are collections. For example, you can enumerate the names of executable and working ...
适用范围:SQL Server Azure 数据工厂中的 SSIS Integration Runtime变量枚举器的 Foreach 枚举通过变量传递给它的各列表项,并对每一项执行相同的任务。 您可以在脚本任务中使用自定义代码来填充用于此目的的列表。 有关枚举器的详细信息,请参阅 Foreach 循环容器。
适用范围:SQL ServerAzure 数据工厂中的 SSIS Integration Runtime 创建继承自ForEachEnumerator基类的类并将DtsForEachEnumeratorAttribute属性应用于该类后,必须重写基类的属性和方法的实现以提供自定义功能。 若要查看自定义枚举器的工作示例,请参阅为自定义 ForEach 枚举器开发用...
why when I make a change to a foreach loop container in a SSIS package it does not save? I am trying to change the base file name and if I change it through either the edit or properties windows, the changes does not save. Fore example i change th...
I tried a few things like a script with for each loop to slow it down. I think I finally split up the load with one task to load the headers and another to load the detail. I would be interested in seeing more of your process. Can you show your full SSIS p...
