Well, given the following data:
sqlite> create table data (id integer, text); sqlite> insert into data values (1, 'test data'); sqlite> select * from data; id text ---------- ---------- 1 test data sqlite> .q
And corrections to your original code
#!/usr/bin/perl use warnings; use strict; use DBI; my $dbh = DBI->connect( "dbi:SQLite2: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; my $sth = $dbh->prepare("SELECT text FROM data WHERE id = '$id_number +'"); $sth->execute(); while (my $record=$sth->fetchrow_hashref()) { print $record->{text} . "\n"; @splitted_string1 = split " ", $record->{text}; } $dbh->disconnect();
Then running the script produces:
helphand@helphand:~> perl sqlite.pl test data helphand@helphand:~>
But, note that @pages is never set to anything, so your mytable ends up with a schema like this CREATE TABLE mytable ( INTEGER);, which is probably not what you want.
