Re^3: Returning multiple rows from pgplsql to DBI

[poj]

Untested but try SELECT * FROM function() with sort on the results set (not in the function). For example

sub mmgb_getAllBooks {
  my $self = shift;   
  my $dbh = $self->dbh;
  my %parm = @_;

  my $p1 = $parm{mmgr_shortname} ? "character varying '$parm{mmgr_shor
+tname}'"
                                 : 'NULL';    
  my $p2 = $parm{direction} ||= 'ASC'; 
    
  my $sql = "SELECT * FROM mmgb_getAllBooks($p1)
             ORDER BY c7 $p2";
    
  my $sth = $dbh->prepare($sql);
  $sth->execute();
  return $sth->fetchall_arrayref();
}

If it works, wouldn't it be the same as RETURN QUERY SELECT ...? At some point I also have to restrict access to function calls and SELECT etc. will become forbidden for security reasons.

I don't want to write select queries at the perl end

How will you call the plpgsql function in your module ?

There are various ways to call a function without using select, e.g. assignment and PERFORM. Although I may be constrained for the case of returning multiple values (although at some point I will still try to get around that)
