I'd recommend connecting with Win32::ODBC and then it is just a matter of knowing your SQL.
examples would be:
update <tablename> set <fieldname>=<value> where <conditions>
delete from <tablename> where <conditions>
or
insert into <tablename> (<field1>,<field2>) values(<value1>,<value2>)
that should be enough to get you tinkering with it.
A helpful trick for learning is to build your SQL statements with the query generator and choose to view the raw SQL.
Also here are a couple of quicky subs you can use to goof with.
sub db_connect
{
$DSN = "foo";
if (!($db = new Win32::ODBC("dsn=bar;uid=user;pwd=pass")))
{
print "Error connecting to $DSN\n";
print "Error: " . Win32::ODBC::Error() . "\n";
exit;
}
}
sub do_query
{
# reads from a var called $SQL
if ($db->Sql($SQL))
{
print "SQL failed. \n";
print "Error: " . $db->Error() . "\n";
$db->Close();
exit;
}
}
