How to insert data from XML to database XML is a general purpose tag based language and very easy to transfer and store data across applications.

Implementing Foreach Looping Logic in SSISOne of the handiest features in SQL Server Integration Services (SSIS) is the ability to implement looping logic within your control flow. By using the Foreach Loop container, you can create a looping structure that iterates through a collection of objects or data values (the members) and take actions specific to each of those members. The Foreach Loop container lets you define a repeating workflow, similar to how you would define a Foreach looping structure in a procedural programming language. For example, suppose you have a folder that contains a set of text files, and each of those files contains data you want to load into a SQL Server database. You can set up a Foreach Loop container in your control flow and then add a Data Flow task to the container.

The Data Flow task will retrieve the data from the files and load the data into the database. Because you’ve set up a looping structure, the Foreach Loop container will execute the Data Flow task multiple times, once for each file in the folder. And the Foreach Loop container is not limited to text files. The container lets you enumerate a variety of collection types, such as rows in a table, SQL Server Management Objects (SMO), the result set of an XML Path Language (XPath) expression, or schema information about a data source.

A simple trick to improve performance of Dynamics CRM C# code is to update an entity without retrieving it from the CRM server. This means only one hit. I am retrieving data from a SQL table so I can display the result on the page as a HTML table. Later I need to be able to save that table as a CSV file. So far I have.

The best way to learn how to use the Foreach Loop container is to see it in action. To this end, the rest of the article demonstrates how to retrieve data from a single SQL Server view and insert that data into multiple comma- separated values (CSV) files. The source data comes from the v. Employee view in the Adventure. Works. 20. 08. R2 database.

The goal is to create a file for each technician type returned by the view. The files will include the technicians’ first and last names and be saved to a local folder.

NOTE: You can download the SSIS package used for this example from the bottom of the article. Adding Your Variables When you use the Foreach Loop container to loop through a collection, you need to define a variable that will provide a pointer to the current member, as you loop through the collection.

You can define that variable in advance or when you configure the Foreach Loop container. In this case, I create the variable in advance so it’s ready when I need it.

I assign the name Job. Title to the variable and configure it with the String data type. For its value, I use a set of quotation marks to represent an empty string; however, you can specify any initial value. Cd Da Novela Duas Caras Internacional Download Youtube.

If you’re going to implement breakpoints and set up watches to monitor variable values when you run the package, then you might want to assign a meaningful value to the Job. Title variable to provide a better milepost during the iterative process. Next, I create a variable named Job. Titles to hold the collection itself. You do not always need to create a second variable. It depends on the collection type. In this case, because I’ll be retrieving data from a view, I need a variable to hold the result set returned by my query, and that variable must be configured with the Object data type.

However, I don’t need to assign an initial value to the variable. The value System. Object is automatically inserted, as shown in Figure 1. Figure 1: Adding the Job.

Title and Job. Titles variables to your SSIS package Because I created the variables at a package scope, they’ll be available to all components in my control flow. I could have waited to create the Job. Title variable until after I added the Foreach Loop container, then I could have configured the variable at the scope of the container. I’ve seen it done both ways, and I’ve done it both ways. Keep in mind, however, if you plan to use the variable outside of the Foreach Loop container, make sure it has a package scope. Configuring Your Control Flow The first step in configuring the control flow is to add a connection manager to the Adventure.

Works. 20. 08. R2 database. In this case, I create a connection to the database on a local instance of SQL Server 2.

R2 and then name the connection manager Adventure. Works. 20. 08. R2. Next, I add an Execute SQL task to my control flow in order to retrieve a list of job titles from the v. Employee view. After I add the task, I open the task’s editor and update the value of the Result. Set property to Full result set. I use this setting because the task will return a result set that contains data from the v. Employee view. I then specify the Adventure.

Works. 20. 08. R2 connection manager in the Connection property, and assign the following Transact- SQL statement to the SQLStatement property: SELECTDISTINCTJob. Title. FROMHuman. Resources. v. Employee. WHEREJob. Title. LIKE'%technician%'My goal is to return a list of unique job titles that include the word technician. Figure 2 shows the General page of the Execute SQL Task editor after I add the Select statement.

Figure 2: Configuring the General page of the Execute SQL Task editor Because the Execute SQL task has been set up to return a result set, you need some place to put those results. That’s where the Job. Titles variable comes in. The task will pass the result set to the variable as an ADO object, which is why the variable has to be configured with the Object data type. The variable can then be used to provide those results to the Foreach Loop container. So the next step in configuring the Execute SQL task is to map the Job.

Titles variable to the result set, which I do on the Result Set page of the Execute SQL Task editor, shown in Figure 3. Buck Tick Romance Mp3 Free Download. Figure 3: Configuring the Result Set page of the Execute SQL Task editor To create the mapping, I click Add and then specify the Job. Titles variable in the first row of the Variable.

Name column. Notice in the figure that I include the User namespace, followed by two colons. I then set the value in the Result Name column to 0.

That’s all you need to do to configure the Execute SQL task. The next step is to add a Foreach Loop container and connect the precedence constraint from the Execute SQL task to the container. Then you can configure the container.

When doing so, you must select an enumerator type. The enumerator type indicates the type of collection you’re working with, such as files in a folder or rows in a table.

In this case, because the result set is stored in the Job. Titles variable as an ADO object, I select the Foreach. ADO enumerator, as shown in Figure 4. Figure 4: Configuring the Collection page of the Foreach Loop editor The Foreach. ADO enumerator lets you access rows of data in a variable configured with the Object data type.

So once I select the enumerator type, I select the Job. Titles variable from the ADO object source variable drop- down list. As for the Enumerationmode option, I leave that at its default setting, Rowsinthefirsttable, because there’s only one table (with only one column). After you configure the Foreach Loop container with the collection, you must create a variable mapping that tells the container which variable to use to store the individual member during each loop. You configure variable mappings on the Variable Mappings page of the Foreach Loop editor, as shown in Figure 5. Figure 5: Configuring the Variable Mappings page of the Foreach Loop editor For my example, I create a mapping to the Job.

Title variable. To do this, I select the variable from the drop- down list in the first row of the Variable column, and set the index to 0. I use 0 because my collection is taken from the first column of the result set stored in the Job.

Titles variable. If there were more columns, the number would depend on the column position. The positions are based on a 0 cardinality, so the first column requires a 0 value in the Index column.

If my result set included four columns and I was using the third column, my Index value would be 2. That’s all there is to setting up the Foreach Loop container for this example. After I complete the setup, I add a Data Flow task to the container.
