in reply to Outputing data from mySQL query into format for use with HTML::Template

A great way to do what you want is built right into DBI, there is no need for extra code to build the data structure:

my %attr = ( dbi_fetchall_arrayref_attr => {}, ); my $statement = q{ SELECT * FROM table WHERE field LIKE ? }; $template->param( rows => $dbh->selectall_arrayref($statement, \%attr, $value), );

This uses a little known, and undocumented feature in DBI, where selectall_arrayref() can be coerced into returning a reference to an array of hash references. This is done through the use of the \%attr hash reference passed to selectall_arrayref().

[james28909]: i figured out a neet trick
[Lady_Aleena]: james28909, what neat trick?
[james28909]: now if i have packed a script into a PDK exe, and misplaced the source, i can print it.
[james28909]: but you have to prepare for it first by adding this to the source
[james28909]: seek DATA, 0, 0; while (<DATA>) { print; }
[Lady_Aleena]: Sounds interesting. Have you written a meditation or cool use for it?
[Lady_Aleena]: It might be something PerlMonks at large would be interested in.
