无法将数据从Java类插入excel表

Question

我使用下面的代码将数据插入Excel工作表。

public class SQLTest {

    Connection conn = null;
    Statement stmnt = null;
    ResultSet RS = null;
    String TestCaseWorkbook = null;
    String TestCaseSheet = null;
    public ResultSet getTestCases() throws SQLException{
        conn = DriverManager.getConnection("jdbc:odbc:Driver={Microsoft Excel Driver (*.xls)};DBQ= C:\\DurgeshProjectWork\\Selenium\\SeleniumTestNGWorkspace\\DevOps\\TestResults\\tmp\\020315_Index.xls");
        stmnt = conn.createStatement();

        String sSQL="insert into [TestSummary$] values ('First_value', 'seondValue', 'Addproductsandplaceorder', '6', '6', '0', 'firefox', 'Pass')";
        System.out.println("Result from function for sSQL = "+sSQL);
        RS = stmnt.executeQuery(sSQL);
        return RS;
    }

    public static void main (String [] args) throws SQLException
    {
        SQLTest st = new SQLTest();
        st.getTestCases();
        System.out.println("Result is = "+st.getTestCases() );
    }

}

但是，我收到以下错误消息。有谁可以帮我解决这个问题

Result from function for sSQL = insert into [TestSummary$] values ('First_value', 'seondValue', 'Addproductsandplaceorder', '6', '6', '0', 'firefox', 'Pass')
