In Object Explorer, right-click Purchasing.CurrencyNEW, and then click Select Top 1000 Rows. 5. Close Microsoft SQL Server Management Studio. Click Yes, then Save to save changes. Results: After completing this exercise, you should have exported the Currency table to a file named currency.dat then imported that data into a new table.

6 Exercise 3: 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.
