I have this piece of code that i can't make any sense of its output. 
#!/usr/bin/perl
 use warnings;
 use strict;
 
 use DBI;
         
 my $dbh = DBI->connect( "dbi:SQLite:dbname=mydatabase.db", "", "" )||
+ die "Cannot connect: DBI";
 
 my @pages;
 # Create the table and make the columns
 my $column_creator = join(' INTEGER,', @pages) . ' INTEGER';
 my $create_columns = "CREATE TABLE mytable ($column_creator)";
 $dbh->do($create_columns);
 
 my $id_number = 1;
 my $current_column;
 my @splitted_string1;
 
 $current_column = $db->query("SELECT text FROM data WHERE id = '$id_n
+umber'")->list;
 print $current_column;
 @splitted_string1 = split " ", $current_column; 
 }

When i run this script the first time the problem is that it cannot write the value from my database file to the $current_column variable. The "text" table is already in my file. It creates the table "mytable" but all it has is the column names.

If i run it for a second time it gives DBD::SQLite::db do failed: table mytable already exists(1) at dbdimp.c line 268 at xxx.pl line xx. What is really weird though is that it actually prints the $current_column variable this time. This error really baffles me. Does anyone know whats happening? Thanks UPDATE: The @pages array has been declared and shebang fixed.
