I am trying to get 3 variables from a table row in MySQL and I am using two books for help and they say to use fetchrow_array or _arrayref to get it. I've tried it several ways as shown in the book but my server keeps responding with: Can't locate object method "fetchrow_array" via package "DBI::db" (perhaps you forgot to load "DBI::db"?)
Are there alternatives to getting the data out from MySQL and assigning it to a variable? Here's two of my last attempts
JayBee says Thanks for your help :)
use warnings; use DBI; use DBD::mysql; use CGI qw( :standard ); use CGI::Carp "fatalsToBrowser"; print header, start_html('SQL Must Work!'); my $dbh = DBI->connect("DBI:mysql:data:server","uname","pass") or die( "Could not make connection to database: $DBI::errstr" ); $dbh->do( qq{SELECT Tab1, Tab2, Tab3 FROM UData } ); while (my @row = $dbh->fetchrow_array ) { my ( $item0, $item1, $item2 ) = @row; if ($item0 >= $somevalue) { print br, "$item0"; } } warn( $DBI::errstr ) if ( $DBI::err ); $dbh->disconnect(); print '<h2>All Done</h2>'; print end_html;
Here's another using STDOUT after SELECT - FROM -, to the disconnect:
my @array; while (my @row = $dbh->fetchrow_array ) { write (); } format STDOUT = @<<<<<<<<<<@<<<<<<<<<<<<<@<<<<<<<< $array[0], $array[1], $array[2] .
