Moves the cursor to the record that most closely matches the current key.
Syntax:
procedure GotoNearest;
Description:
Call GotoNearest to position the cursor on the record that is either the exact record
specified by the current key values in the key buffer, or on the first record whose values exceed those
specified.
KeyExclusive determines which records are considered part of a search range.
Before calling GotoNearest, an application must specify key values by calling
SetKey or EditKey to put the dataset is dsSetKey state, and then use
FieldByName to populate the key buffer property with search values.
Delphi 7 and prior has poor support for int64 values in variant type. This means
that you'll be unable to use Locate() and similar methods with such fields. Lookup fields and
master-detail tables will not work properly too because of their dependence on Locate() method.
Please update your IDE to BDS 2006 (or later) or don't use BIGINT and UNSIGNED INT datatypes
for keys and indexes if you need to use them in lookup fields. Also you can't use variant-style
properties (FieldValues, AsVariant and so on) with such fields.
