Version 0.06

SYNOPSIS

  $db  = Bio::DOOP::DBSQL->connect("user","pass","database","localhost");

  $res = $db->query("SELECT * FROM sequence LIMIT 10");

  foreach (@$res) {
     @fields = @{$_};
     print "@fields\n";
  }

DESCRIPTION

This object provides low level access to the MySQL database. In most cases you do not need it, because the DOOP API handles the database queries. Still, if you need some special query and the DOOP API can't help you, use the query method to access the database.
