Srs.,
Ao me conectar com uma aplicação em Java no MySQL (ver. 4.1) só consigo fazer aparecer um campo do tipo long. Os campos do tipo String não aparecem. (Todos os campos da tabela são varchar). Creio que seja alguma configuração do driver. segue o erro abaixo.
Conto com a ajuda dos srs.,
Obrigado.
