Hi,

in fact, the bug has nothing to do with xkeyval (sorry), but if \DTLnewdbentry's third argument (value of the identifier key) is an empty macro.

The following MCE shows the problem:

  \DTLnewdbentry{mydata}{Surname}{\test}%

is OK as long as \test is a non-empty macro (uncomment penultimate line to bring out the error).

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\documentclass{article}
\usepackage{datatool}
%
\newcommand{\test}{}
%
\begin{document}
%
\DTLnewdb{mydata}%
%
\renewcommand{\test}{Doe}
\DTLnewrow{mydata}%
\DTLnewdbentry{mydata}{Surname}{\test}%
%
\renewcommand{\test}{}
\DTLnewrow{mydata}%
% \DTLnewdbentry{mydata}{Surname}{\test}%
\end{document}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
