Pessoal sou iniciante,
Estou criando um cadastro de fornecedor mas quando coloco pra salvar aparece o erro
public class ControleFornecedor {
ConectaBanco conn = new ConectaBanco();
public void Salvarforn(ModeloFornecedor mod){
conn.conexao();
try {
PreparedStatement pst = conn.conn.prepareStatement("insert into fornecedor(Razaosocial_fornecedores,cnpj_fornecedores,inscricaoestadual_fornecedores,contato1_fornecedores,contato2_fornecedores,vendedor_fornecedores,cidade_fornecedores,cep_fornecedores,uf_fornecedores)values(?,?,?,?,?,?,?,?,?)");
pst.setString(1, mod.getRazaosocial());
pst.setString(2, mod.getCnpj());
pst.setString(3, mod.getInscricaoestadual());
pst.setString(4, mod.getContato1());
pst.setString(5, mod.getContato2());
pst.setString(6, mod.getVendedor());
pst.setString(8, mod.getCidade());
pst.setString(9, mod.getCep());
pst.setString(10, mod.getUf());
pst.execute();
JOptionPane.showMessageDialog(null,"Dados inseridos com sucesso!");
} catch (SQLException ex) {
JOptionPane.showMessageDialog(null,"Erro na inserção do fornecedor!");
}
conn.desconecta();
}
o erro é esse
