Bulk Operations
 
 
- Execute a statement for multiple values
- 
$sth = $dbh->prepare("insert into table (foo,bar) values (?,?)");
 
 $tuples = $sth->execute_array(\%attr, \@list_of_param_array_refs);- 
- returns count of executions, even ones that failed, and not rows-affected
- 
 
 
- Explicit array binding
- 
$dbh->bind_param_array(1, \@array_of_foo_values, \%attr);
 
 $dbh->bind_param_array(2, \@array_of_bar_values, \%attr);
 $sth->execute_array(\%attr) # uses bind_param_array values
 
- Attributes for row-wise binding and per-tuple status:
- 
ArrayTupleFetch => $code_ref_or_sth	row-wise binding
 
 ArrayTupleStatus => $array_ref		return rows-affected and errors
 
- DBI provides default methods that work for all drivers
- 
- Some drivers support use of specific database API for very high performance
