      OR  $sqlq = $self->new(-select=>["col1", "col2"],
                             -table=>["table1", "table2"], 
                             -where=>["col3='val1'", "col4='val4'"]);
      OR  $sqlq = $self->new("col1, col2", "col1.fk=col2.pk", "*", "col2,col1");
      OR  $sqlq = $self->new("col1", {col1=>$val1, col2=>$val2});

  Args: tables, where, select, order, group, sql

all arguments except table are optional (select defaults to *)
