如何使用select命令将单元格的值从网格视图存储到数据库？

import java.sql.*;

public class GridviewToDatabase {
    public static void main(String[] args) {
        // 数据库连接信息
        String url = "jdbc:mysql://localhost:3306/mydatabase";
        String username = "root";
        String password = "password";

        // 建立数据库连接
        try (Connection conn = DriverManager.getConnection(url, username, password)) {
            // 查询网格视图数据
            String selectQuery = "SELECT cell_value FROM gridview";
            try (Statement stmt = conn.createStatement();
                 ResultSet rs = stmt.executeQuery(selectQuery)) {
                // 存储数据到数据库
                String insertQuery = "INSERT INTO table_name (column_name) VALUES (?)";
                try (PreparedStatement pstmt = conn.prepareStatement(insertQuery)) {
                    while (rs.next()) {
                        String cellValue = rs.getString("cell_value");
                        pstmt.setString(1, cellValue);
                        pstmt.executeUpdate();
                    }
                }
            }
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}
