Olá, aqui estou eu novamente alterei a forma de consultar, porem acho que não estou fazendo do modo correto, pois esta dando um erro.
Este é o metodo para consulta no banco
public List<FinancasModel> listaPorDatas(Date dataInicio, Date dataFinal) {
String sql = "select codfinancas, valor, dataPagamento, dataCadastro, observacao, f.codcategoria, c.descricao, c.tipo "
+ "from financas f inner join categoria c on c.codcategoria = f.codcategoria "
+ "where dataPagamento between ? and ?";
List<FinancasModel> listaPorDatas = new ArrayList<>();
try {
PreparedStatement ps = getCon().prepareStatement(sql);
ps.setDate(1, new java.sql.Date(dataInicio.getTime()));
ps.setDate(2, new java.sql.Date(dataFinal.getTime()));
ResultSet rs = ps.executeQuery();
if (rs != null) {
while (rs.next()) {
FinancasModel fm = new FinancasModel();
fm.setCodFinancas(rs.getInt(1));
fm.setValor(rs.getDouble(2));
fm.setDataPagamento(rs.getDate(3));
fm.setDataCadastro(rs.getDate(4));
fm.setObservacao(rs.getString(5));
CategoriaModel cm = new CategoriaModel();
cm.setCodCategoria(rs.getInt(6));
cm.setDescricao(rs.getString(7));
cm.setTipo(rs.getString(8));
fm.setCodCategoria(cm);
listaPorDatas.add(fm);
}
} else {
return null;
}
} catch (SQLException e) {
JOptionPane.showMessageDialog(null, "Erro: " + e);
}
return null;
}
E este é o método para exibir o resultado pro usuário
public void listaPorDatas(Date dataInicio, Date dataFinal) {
FinancasDAO cd = new FinancasDAO(con);
DefaultTableModel model = (DefaultTableModel) tbl_movimentacao.getModel();
model.setNumRows(0);
List<FinancasModel> listaPorDatas = cd.listaPorDatas(dataInicio,dataFinal);
double despesa = 0;
double renda = 0;
for (FinancasModel fb : listaPorDatas) {
if (fb.getCodCategoria().getTipo().equals("DESPESA")) {
despesa += fb.getValor();
} else {
renda += fb.getValor();
}
model.addRow(new Object[]{
fb.getCodFinancas(),
Utils.ConverteDouble(fb.getValor()),
Utils.converteData(fb.getDataPagamento()),
fb.getCodCategoria().getTipo(),
fb.getCodCategoria().getDescricao(),
fb.getDataCadastro(),
fb.getObservacao()
});
}
txt_despesa.setText(Utils.ConverteDouble(despesa));
txt_renda.setText(Utils.ConverteDouble(renda));
txt_saldo.setText(Utils.ConverteDouble(renda - despesa));
}
E este é o erro
