in reply to question about printing from database

Greetings Thargor,

I am also a newbie, and have needed to to do something very similar many times. Here is the format I usually use.

############################################################ sub getInfo ############################################################ { my ($dbh, $sth, %data); $dbh=DBI->connect('DBI:ODBC:my_table', { RaiseError => 1, AutoCommit = +> 0 }); $sth = $dbh->prepare( "Select * FROM my_table" ); $sth->execute; $sth->bind_columns( \( @data{ @{$sth->{NAME_lc} } } )); #----Saves sp +eed by binding columns to their values. $sth->{'ChopBlanks'} =1; #----Removes extra spaces from fixed char +fields. $data{$_} = (defined $data{$_}) ? $data{$_} : '' for keys %data; #--- +-Changes null values to "" as per jZed to avoid warnings while ($sth->fetch) { print qq(<TR>\n); print qq(<TH>$data{col1name}</TH>\n); #use real column names print qq(<TH>$data{col2name}</TH>\n); print qq(<TH>$data{col3name}</TH>\n); print qq(<TH>$data{col4name}</TH>\n); print qq(</TR>\n); } $sth->finish(); $dbh->disconnect(); ----Needed to free up system resources. }
Hope this also helps.
