Amigos estou desenvolvendo um trabalho de faculdade, e de tanto tentar e não consegui resolver, venho aqui no forum para pedir ajuda.
//diminuir o estoque
for(int i=0; i<modelo.getRowCount();i++)
{
String cod=modelo.getValueAt(i,0).toString();
String quant=modelo.getValueAt(i,2).toString();
sql = "SELECT pro_estoque FROM produto WHERE pro_cod="+cod;
ResultSet rs = Banco.con.consultar(sql);
int subtraiEstoque = 0;
try
{
subtraiEstoque = rs.getInt("pro_estoque") - Integer.parseInt(quant); // ACHO QUE O ERRO ESTA EM ACESSAR O BANCO DE DADOS PARA PEGAR O VALOR ATUAL NO ESTOQUE E SUBTRAIR PELA QUANTIDADE QUE O CLIENTES ESTA COMPRANDO
} catch (SQLException ex) {
Logger.getLogger(TelaTrocaOleo.class.getName()).log(Level.SEVERE, null, ex);
}
sql="UPDATE produto SET pro_estoque='#1' WHERE pro_cod="+cod;
sql = sql.replace("#1", String.valueOf(subtraiEstoque));
if(Banco.con.manipular(sql))
JOptionPane.showMessageDialog(this, "Cadastrado ------- 3 !");
else
JOptionPane.showMessageDialog(this, "Erro ---------- 3 "+Banco.con.getMensagemErro());
}
