mysql循环生成别名

import mysql.connector

# 连接到MySQL数据库
db = mysql.connector.connect(
    host="localhost",
    user="yourusername",
    password="yourpassword",
    database="yourdatabase"
)

cursor = db.cursor()

# 假设我们有一个表名为table1，列名为column1, column2, column3
table_name = "table1"
columns = ["column1", "column2", "column3"]

# 动态生成别名
aliased_columns = [f"{col} AS {col}_alias" for col in columns]

# 构建SQL查询语句
query = f"SELECT {', '.join(aliased_columns)} FROM {table_name}"

# 执行查询
cursor.execute(query)

# 获取结果
results = cursor.fetchall()

# 打印结果
for row in results:
    print(row)

# 关闭连接
cursor.close()
db.close()
