Declaration
function KeyData: String;
Description
Extracts the key data from the current index key in the current index and returns it as a string.
Return Value
Numeric keys return a string representation of the number to four decimal places. Logical keys return 'T' or 'F'. Date key return values differ according to the index type. NTX dates are returned as a string in CCYYMMDD format. IDX/CDX/NSX dates are returned as a string representation of the Julian date (see GetDateJulian) - unless they have been turned into strings with DTOS().
Delphi Example
with ApTbl do
begin
Open;
Index( 'test.idx', 'upper(STATE+CITY)', IDX_NONE, False, '' );
GoTop;
Edit1.Text := KeyData; // Contains 'AKANCHORAGE '
end;
C++Builder Example
ApTbl->Open();
ApTbl->Index( "test.idx", "upper(STATE+CITY)", IDX_NONE, false, "" );
ApTbl->GoTop();
Edit1->Text = ApTbl->KeyData(); // Contains "AKANCHORAGE "
