SSIS Export SQL Data to Fixed Width Flat File
Drag the Data Flow Task into the control flow region.
Here, we have chosen the existing one, but you can create a fresh one by clicking the New button.
We choose the Employee table from the list of available ones. Next, go to the columns tab to check the columns and click the Ok button.
Drag the flat file destination and connect the OLE DB source to it. Next, Double-click on the flat file destination to open the Editor, and click on the new button to choose the Fixed Width as the flat file format.
Click the Browse button to create a new file to store the Fixed Width records.
Next, checkmark the Column Names in the first data row option to copy the headers.
Within the Advanced tab, change the InputColumnWidth value to adjust the row items. For instance, EmpID = 8, FirstName = 25, etc.
Change the InputColumnWidth value for the remaining columns. After you finish, click OK to close the window.
Within the Flat File Destination Editor, go to the Mappings tab to check the input and available destination column mapping.
Run the SSIS Export SQL Server Table Data to Fixed Width Flat File package.
As you can see, the text file has all the records in a single line or row where a Fixed Width of space separates each value.
