in reply to Syntax question when using Class::DBI
There is no problem with using a simple scalar variable when dynamically calling a method, as Fletch illustrated. However if you're using an aggregate variable or an expression you can simply use the can method e.g
Or if you wish to call it directly you need to be a little indirect and take advantage of scalar dereferencing e.gprint $rowobj->can( $cols{id} )->();
Addendum: On a more practical note you can always access the primary key by using the id accessor method, regardless of what is the name of the actual row; as documented.print $rowobj->${ \$cols{id} };
