如何删除表行中的空值

import pandas as pd

# 读取表格数据
df = pd.read_csv('table.csv')

# 删除包含空值的行
df.dropna(inplace=True)

# 打印删除后的结果
print(df)

import java.sql.*;

public class DeleteEmptyRows {
    public static void main(String[] args) {
        String url = "jdbc:mysql://localhost:3306/database";
        String username = "root";
        String password = "password";

        try {
            Connection connection = DriverManager.getConnection(url, username, password);
            Statement statement = connection.createStatement();

            // 删除包含空值的行
            String sql = "DELETE FROM table WHERE column IS NULL";
            int rowsAffected = statement.executeUpdate(sql);

            System.out.println("删除了 " + rowsAffected + " 行");

            statement.close();
            connection.close();
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}
