For Each Loop Container

SSIS Package For Each Loop Container

         The For Each Loop Container defines a repeating control flow in the package. Loop implementation in the For Each Loop Container is similar to the Foreach looping concept in various programming languages. The Foreach enumerator enables looping in a package.

There are several different enumerator types available.  They are:

     1) Foreach File Enumerator

The File Enumerator enumerates files in a folder. For example, we can get all the files which have the *.txt extension in a windows folder and its subfolders.

    2) Foreach ADO Enumerator

The ADO Enumerator enumerates rows in a table. For example, we can get the rows in the ADO records.

    3) Foreach ADO.Net Schema Rowset Enumerator

The ADO.Net Enumerator enumerates the schema information. For example, we can get the table from the database.

    4) Foreach Item Enumerator

The Item Enumerator enumerates the collections. For example, we can enumerate the names of executables and working directories that an “Execute Process” task uses.

   5) Foreach Nodelist Enumerator

The Node List Enumerator enumerates the result of an XPath expression.

   6) Foreach From Variable Enumerator

The Variable Enumerator enumerates objects that specified variables contain. Here enumerator objects are nothing but an array or data table.

   7) Foreach SMO Enumerator

The SMO Enumerator enumerates SQL Server Management Objects (SMO). For example, we can get the list of functions or views in a SQL Server database.
