               After a table and its columns are defined, we can then populate the table with data from a file.
               We can also create an index to improve query processing and define a view, or virtual table, to
               limit access to specific columns.
               10.3.4  Populate a Table Using the Import Assistant
               We can populate a table with data by importing the data from a file. The Ingres Import Assistant
               can import data from various file types.
               In this example, we use a CSV file located in %II_SYSTEM%\ingres\demo\data\airport.csv.


                              The airport table in the demodb is already populated. This sample procedure
                              creates a new table called temp, which we can delete (drop) after this exercise.


               10.3.5  To Import Data From a File Using the Import Assistant


                  1. Click the Ingres Import Assistant button    on the toolbar in Visual Manager. Step 1
                    of 4 of the Import Assistant is displayed.
                  2. Use the browse button in the File to be imported control to locate the file.
                  3. Expand the (local) node in the Into Ingres Table control, and then expand the demodb
                    database. Select the <new table> option and enter temp into the Ingress Table to be Created
                    field. Press  Next. Step 2 of 3 of the Import Assistant (File Format Identification) is
                    displayed. The Import Assistant displays each of its interpretations of the data as a tab.
