Selecting columns
In this step of the wizard you are to select the table columns from which the data should be saved.
To select a column, you need to move it from the Available columns list to the Selected columns list. Use the buttons or drag-and-drop operations to move the columns from one list to another.
If you need to copy all available columns, you can select the All columns option.
Click the Next button to proceed to the Specifying type of output file step of the wizard.
