The standard BETWEEN comparison predicate is supported. It generates SQL of the form expression BETWEEN expression AND expression. The Between predicate evaluates to true if the first expression is greater than or equal to the second expression at the same time that it is less than or equal to the third expression. When dragging a Between operator into a variable, the following tree element is created.
Columns and/or other expressions can be moved into the (empty) branches of the tree, the first argument being the expression to the left of the BETWEEN, the second to the right, and the third to the right of the AND.
There are no special properties for the Between operator.
