Final answer:
Double-clicking the title bar is not a method used to add fields to a query design grid. Methods that are used include dragging, Click, Shift, Click, and single-clicking the field name.
Step-by-step explanation:
The method that is NOT used to add fields to a query design grid is double-clicking the title bar. In database software such as Microsoft Access, fields can be added to a query design grid by:
- Dragging the field from the table to the query design grid.
- Using the Click, Shift, Click method to select multiple fields and then dragging them or using the Add button to place them on the grid.
- Single-clicking the field name in the table list, which adds it individually to the grid.
Double-clicking the title bar is generally not associated with field selection in query design and is more a window management action (such as maximizing the window).
