我在Excel文件中有上述信息，我想选择并输出2013年7月AllTXN_Issued的值作为上个月交易的总和。在使用jdbc-odbc连接连接Excel电子表格后，如何在Java中执行此操作？

Answer 1

试试这个，它适用于所有平台。

Fillo fillo=new Fillo();
Connection connection=fillo.getConnection("C:\\Test.xlsx");
String strQuery="Select * from Sheet1 where ID=100";
Recordset recordset=connection.executeQuery(strQuery);

while(recordset.next()){
System.out.println(recordset.getField("Details"));
}

recordset.close();
connection.close();

以下代码适用于我。它假设Excel中的[MetricMonth]列包含文本值（而不是格式化为MMM-yyyy的真实日期），但它至少应该为您提供一般的想法。

import java.sql.*;

public class jdbcTest {

    public static void main(String[] args) {
        try {
            Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
            Connection conn = DriverManager.getConnection(
                    "jdbc:odbc:Driver={Microsoft Excel Driver (*.xls, *.xlsx, *.xlsm, *.xlsb)};" + 
                    "Dbq=C:\\__tmp\\Book1.xlsx;");

            PreparedStatement s = conn.prepareStatement(
                    "SELECT * FROM [Sheet1$] WHERE [MetricMonth] = ?");
            s.setString(1, "Jul-2013");
            s.execute();
            ResultSet rs = s.getResultSet();
            if (rs!=null) {
                while (rs.next()) {
                    System.out.println(rs.getInt("AllTXN_Issued"));
                }
            }
            s.close();

            conn.close();
        } catch( Exception e ) {
            e.printStackTrace();
        }

    }

}

Fillo fillo=new Fillo();
Connection connection=fillo.getConnection("C:\\Test.xlsx");//Path to your excel workbook
String strQuery="Select * from SheetName where Open_YYYY = 2013 and MetricMonth like '%Jul%'";
Recordset recordset=connection.executeQuery(strQuery);

while(recordset.next()){
System.out.println(recordset.getField("AllTXN_Issued"));
}

recordset.close();
connection.close();
