Configuring SSIS Flat File connection manager
In this task, you add a Flat File connection manager to the package that you just created. A Flat File connection manager enables a package to extract data from a flat file. Using the Flat File connection manager, you can specify the file name and location, the locale and code page, and the file format, including column delimiters, to apply when the package extracts data from the flat file. In addition, you can manually specify the data type for the individual columns, or use the Suggest Column Types dialog box to automatically map the columns of extracted data to Integration Services data types.
You must create a new Flat File connection manager for each file format you're working with. Because this tutorial extracts data from multiple flat files that all have the same data format, you only need to add and configure one Flat File connection manager for the example package.
In this lesson, you configure the following properties in your Flat File connection manager:
Column names: Since the flat file does not have column names, the Flat File connection manager creates default column names. These default names are not useful for identifying what each column represents. Change the default names to names that match the fact table into which the flat file data is to be loaded.
Data mappings: The data type mappings that you specify for the Flat File connection manager are used by all flat file data source components that reference this connection manager. You can either manually map the data types by using the Flat File connection manager, or you can use the Suggest Column Types dialog box. In this task, you view the mappings suggested in the Suggest Column Types dialog box and then manually create the necessary mappings in the Flat File Connection Manager Editor dialog box.
