New Computed Column Dialog

The New Computed Column dialog appears when you select Menu > Column > New Computed Column, or select New Computed column in the Query Editor. It helps you to create functions quickly and easily instead of having to write formulas. See the dialog.

The following are details about options in the dialog:
