Summary \DTLminforcolumn does not work for empty fields

Sign in to subscribe to notifications about this report.

Description

See [TeX.SX Link] for an MWE as well as a possible fix.

Basically, applying \DTLminforcolumn to a column that contains empty fields will forget the minimum found so far and restart with the next value.

Not sure whether the behaviour of \DTLminforcolumn for empty fields should depend on \ifDTLlistskipempty; didn't read enough of the manual to fully understand its semantics.

\begin{filecontents*}{example1.csv}

test1;1
test2;
test3;3
test4;2

\begin{filecontents*}{example2.csv}
title;value
test1;1
test2;2

    \DTLsetseparator{;}%

    \DTLminforcolumn{a}{value}{\minValueFirstExample}
    
    \DTLsetseparator{;}%
    \DTLloaddb{b}{example2.csv}
    \DTLminforcolumn{b}{value}{\minValueSecondExample}
    
    Min Value1: \minValueFirstExample\\ %Should be 1 and not 2
    Min Value2: \minValueSecondExample %Is correct
\end{document}
