Exercise 1: Using the Import/Export Wizard
Scenario
Legacy systems at Adventure Works require product data in comma-delimited text files.
Also, a flat file containing information from a legacy system needs to be imported into a
new SQL Server database. First, You must export data from the Person.Contact table in
the AdventureWorks database to a text file, then import that data into a new database.

Exercise 3: Demonstration: Using the OPENROWSET Function
Demonstration Steps
Use the OPENROWSET Function to Import Data
1. Ensure that you have completed the previous demonstrations in this module.
2. In SQL Server Management Studio, in Object Explorer, right-click the dbo.SalesTaxRate table in the
Finance database, and click Select Top 1000 Rows.

FORMATFILE = 'D:\Demofiles\Mod06\TaxRateFmt.xml') AS rows;
5. Click Execute and note the number of rows affected.
Switch to the query pane that retrieves the top 1000 rows from the dbo.SalesTaxRate table and click
Execute to re-run the SELECT query. Note that the table is now populated with the same number of
rows
as you noted in the previous step.
Exercise 4: Creating an SSIS Solution
Scenario
For another legacy system, you must use SSIS create a text file that consists of the
ProductID and Name columns from the Production.Product table, and a column named
Price that is derived from the ListPrice column in the Production.Product table that
displays the price using the currency format defined by the locale of the computer.
The SSIS package must display a confirmation message when the data has been exported.
