TCustomClientDataSet.KeyExclusive Property

Specifies the upper and lower boundaries for a range.

Pascal
property KeyExclusive: Boolean;
C++
__property Boolean KeyExclusive;

Use KeyExclusive to specify whether a range includes or excludes the records that match its specified starting and ending values. By default, KeyExclusive is false, meaning that matching values are included. 

To restrict a range to those records that are greater than the specified starting value and less than the specified ending value, set KeyExclusive to true.
