1,Monday,A
2,Tuesday,B
3,Wednesday,D
30,Thursday,C
31,Friday,M
131,Saturday,N
132,Sunday,K

\end{filecontents*}
\usepackage{datatool}
\DTLloaddb[autokeys=false]{file}{file.tex}
\newcommand\Sundaycode{1}
\newcommand\Mondaycode{2}
\newcommand\Tuesdaycode{3}
\newcommand\Wednesdaycode{4}
\newcommand\Thursdaycode{5}
\newcommand\Fridaycode{6}
\newcommand\Saturdaycode{7}
\newcommand\daycode[1]{\csname #1code\endcsname}
\begin{document}
