如何在Python cursor.execute中查看真正的SQL查询

import psycopg2

# 建立数据库连接
conn = psycopg2.connect(database="your_database", user="your_username", password="your_password", host="your_host", port="your_port")
cursor = conn.cursor()

# 定义SQL查询
sql = "SELECT * FROM your_table WHERE column = %s"

# 定义参数值
params = ("some_value",)

# 执行SQL查询
cursor.execute(sql, params)

# 查看真正的SQL查询
query = cursor.mogrify(sql, params)
print(query)

# 获取查询结果
result = cursor.fetchall()
print(result)

# 关闭数据库连接
cursor.close()
conn.close()
