You can also directly ask DBI to return you a hash:

my $hash = $sth->fetchrow_hashref();

    Sure you can (presuming the query produces the desired column names).

    I was mainly trying to answer the general case, i.e. the typical "beginner's" problem of wanting to dynamically create variables like

    $xxx = "$DBNAME,$USERNAME,$PROFILE"; my ( '$xxx' ) = ( ... );

[Cosmic37]: now I have tried another blunder - can anyone explain why I am such a dunderhead?
[Cosmic37]: if ( $line =~ /$mydt/ ) { print $line; }
[Cosmic37]: I try to match successive date times stored in variable $mydt
[Cosmic37]: I guess it is searching for the string "$mydt"
[Corion]: Indeed cool, erix ;)
[Cosmic37]: rather than the value of $mydt which is a date time strong such as 2016-01-01 12:30:56
[Corion]: Cosmic37: No, but maybe $mydt doesn't contain what you think it does, or it contains characters that are special in a regular expression? Try if( $line =~ /\Q$mydt\E/) { ... for a literal match
[Cosmic37]: I mean string grrr
[Corion]: Maybe add an else branch in which you print what the values of $line and $mydt are?
[Cosmic37]: ah thank you I will try
