SSIS Foreach ADO.NET Schema Rowset Enumerator

The SSIS Foreach ADO.NET Schema Rowset Enumerator is used to enumerate the SQL Server Objects. For example, you can use this SSIS Foreach ADO.NET Schema Rowset to loop over the Views, Schema, Tables, Indexes, Constraints, etc., present in a Database.

In this article, we will show how to find the Views in a SQL Server Database using SSIS Foreach ADO.NET Schema Rowset Enumerator with example.

SSIS Foreach ADO.NET Schema Rowset Enumerator Example

For the SSIS Foreach ADO.NET Schema Rowset Enumerator demo purpose, we will enumerate views present in Adventure Works 2014 database. And copy the View name, Schema names into another database table. To do so, First Drag and drop the Foreach Loop Container into the Control Flow region as shown below

Double click on it will open the Foreach Loop Editor to configure it. Within the General tab, Please specify valid and more meaningful Name and Description. From the below screenshot, you can see that we changed the default name to SSIS Foreach ADO.NET Schema Rowset Enumerator

Next, go to the SSIS Collections tab to select the Enumerator and configure the connections. From the below screenshot, you can observe that we are selecting Foreach ADO.NET Schema Rowset Enumerator because we want to loop over the views present in our Adventure Works 2014 database.

Once you select the SSIS Foreach ADO.NET Schema Rowset Enumerator, two new properties appeared.

• Connection: You have to specify the connection that will connect with the database.
• Schema: This drop-down list has several options, such as Tables, Views, Constraints, Indexing, etc.

First, we will configure the Connection. To do so, click on the down arrow button and select the New Connection.. button to create a new one or else select the existing connection manager (if any).

Once you click on the New Connection.. button, Connection manager Editor opened to configure it. For this example, we are selecting PRASAD as a server instance, and we are using Windows authentication.

Next, please select the schema that you want to loop. Here we are selecting Views.

This window has one more button called Set restrictions.. Let me show you the properties inside this button by clicking it

You can use this window to restricts the data returned by the Foreach Loop.

As you can from the above screenshot, our information schema of Views will return three columns. So, let me created three variables of type string. Next, select the variables and assign them to index 0, 1, 2. Once you complete, Click OK to finish configuring the Foreach Loop Container.

Next, Drag and drop the Execute SQL Task from the toolbox to the Foreach loop container. This task will help us to insert the new values into our Empty table.

Double click on it will open the Execute SQL Task Editor window. Here, we selected OLE DB as the Connection type. And we chose the existing connection, which is pointing to [SQL Tutorials] Database.

TIP: Please refer to the OLE DB Connection manager article to understand the steps involved in creating a new OLE DB Connection.

Next, we are writing the following SQL Query.

INSERT INTO [dbo].[AdventureWorksViews] (TABLE_CATALOG, TABLE_SCHEMA, TABLE_NAME)
                                 VALUES (?, ?, ?)

Here three question marks will be replaced by three-parameter.

Please cross-check all the properties before you start parameter mapping

Next, go to parameter mapping and select the parameter that we assigned in the Foreach Loop container. It means the Foreach loop container will loop through the Views present in the AdventureWorks database and store them in these variables. Next, we are passing those variables into Execute SQL task

Click OK to finish configuring the SSIS Foreach ADO.NET Schema Rowset Enumerator package. Let us Run the package

Let us open the SQL Server management studio and check whether we inserted the views into the destination table using Foreach ADO.NET Schema Rowset Enumerator or not

Now, let me restrict the table schema to Sales only.

Now you can see, it is only returning the Views with Sales schema

Below screenshot will show you the schema details for the Adventure Works
