Hi Monks,

I have a simple SQLite database. I read the content of the table and print it out (in a TK table). When printing it out, I need to sort the entries in an alphabetical order. Easy for English, but I have a small set of non-ASCII characters, such as german ä/ü/ö. I came up with:

order by column collate NOCASE

Result (orderd):
a
g
x
ä

Right order:
a
ä
g
x

My script:

$dbh = DBI->connect( "dbi:SQLite:files/database/data.db" ) || die "Can
+not connect: $DBI::errstr";

$selected = $dbh->selectall_arrayref("SELECT ID,column1,column2  FROM 
+table order by column1 collate NOCASE");

foreach my $row_db (@$selected ) {
my ($ID, $column1, $column2) = @$row_db;
print "$column1\n";
}

One day of manuals and goole gave me no clue! (Mea culpa)!

I am not familiar with creating new collate in perl. Unfortunatelly I didn't find any example out there. I thought even about the posibility to substitute ä->a before performing SELECT. Or... maybe doing the sorting in perl at the stage of 'foreach' (@$selected), maybe not the best solution, but probably the easiest one.

Can any of you suggest a - possible easy - way to solve the problem?

THANXS Cla
