如何在Java中将结果添加到MySQL存储过程的结果集中

Question

I want to add the results to the resultset and use table to display the results it's my java code

while (resultSet.next()) {

            Object[] objects = {
                    resultSet.getDouble("January"),
                    resultSet.getDouble("February"), 
                    resultSet.getDouble("March"),
                    resultSet.getDouble("April"),
                    resultSet.getDouble("May"),
                    resultSet.getDouble("June"), 
                    resultSet.getDouble("July"),
                    resultSet.getDouble("August"), 
                    resultSet.getDouble("September"),
                    resultSet.getDouble("October"), 
                    resultSet.getDouble("November"),
                    resultSet.getDouble("December"), 
                     };
            model.addRow(objects);
        }

The error shows "Column 'Janunary' not found."

I am sorry that I haven't earn sufficient reputation, so I write the result of stored procedure as follows.

categoryid  January   February....

1      3000      5000      (double)....

The Query code:

CallableStatement callableStatement = connection.prepareCall(sql);
        if (cobAccount.getSelectedIndex() != 0) {
            String accountid = cobAccount.getSelectedItem().toString()
                    .substring(0, 1);
            callableStatement.setString(1, accountid);
        } else {
            callableStatement.setString(1, "0");
        }
        if (cobYear.getSelectedIndex() != 0) {
            String year = cobYear.getSelectedItem().toString();
            callableStatement.setString(2, year);
        } else {
            callableStatement.setString(2, "0");
        }
        if (cobMember.getSelectedIndex() != 0) {
            String memberid = cobMember.getSelectedItem().toString()
                    .substring(0, 1);
            callableStatement.setString(3, memberid);
        } else {
            callableStatement.setString(3, "0");
        }
        if (!"".equals(txtMinmoney.getText())) {
            double minMoney = Double.valueOf(txtMaxmoney.getText());
            callableStatement.setDouble(4, minMoney);
        } else {
            callableStatement.setDouble(4, '0');
        }
        if (!"".equals(txtMaxmoney.getText())) {
            double maxMoney = Double.valueOf(txtMaxmoney.getText());
            callableStatement.setDouble(5, maxMoney);
        } else {
            callableStatement.setDouble(5, '0');
        }

Answer 1

Make sure the string you pass for the getDouble function are the actual names of your SQL columns. For example, Janunary does not seem to be spelled correctly.

Answer 2

you skip January with your resultSet.next() no?

maybe do resultSet.hasNext() or equivelant and resultSet.next() at the end of your loop?

Answer 3

It looks like there isn't a column named January. Is there a column named "Month" with a value of Jan/Feb/etc? If you could post the table definition and query, troubleshooting would be easier.
