Re: Looking for a simpler DBI solution.

in reply to Looking for a simpler DBI solution.

I am building a small web based application and have abstracted my database calls (updates, queries and deletes) into a single sub that I then call with up to 2 parameters. The first parameter is the query itself. The second is any data to be inserted. The sub will return the results (if any). This has really helped me to simplify the database calls within my application.

sub db_do { my (%attr) = ( RaiseError => '1'); my $dbh = DBI->connect('DBI:mysql:DATABASE:localhost', 'userna +me', 'password', \%attr); my ($dbq) = shift; my @args = @_; my $sth = $dbh->prepare("$dbq"); $sth->execute(@args); my $result; my @results; if ($dbq =~ /select/i) { my @row; while (@row = $sth->fetchrow_array) { push @results, [ @row ]; } $result = \@results; } $sth->finish; $dbh->disconnect; return $result; } Note that this doesn't handle errors as it should yet, but is function +al. An example of how I use it would be: my $dbq = qq{ INSERT INTO pagers (ptype,pnum,ppin,enum) VALUES (?,?,?, +?) }; my $res = db_do("$dbq", "$ptype", "$pnum", "$ppin", "$enum"); or for a simple select: my $dbq = qq{ SELECT email from email where email = ? }; my $res = db_do("$dbq", "$email");

Without seeing your data, it's difficult to say, but your problem might be that your data needs to be quoted properly to accomplish the insert. The $sth = $dbh->prepare($dbq) statment above will accomplish this for you.

Hope this helps!
