函数计算访问数据库 Python 示例工程

示例包括如下两部分内容：

1. 在 initializer 中创建数据表

   try:
       conn = getConnection()
       with conn.cursor() as cursor:
       sql = """CREATE TABLE IF NOT EXISTS users (
           id        VARCHAR(64) NOT NULL,
           name    VARCHAR(128) NOT NULL,
           PRIMARY KEY(id))"""
       cursor.execute(sql)
       conn.commit()
   finally:
       conn.close()

2. 在 handler 中插入并查询数据

   try:
       conn = getConnection()
       with conn.cursor() as cursor:
       sql = "REPLACE INTO users (id, name) VALUES(%s, %s)"
       cursor.execute(sql, ('2', 'wan'))
       cursor.execute("SELECT * FROM users")
       result = cursor.fetchone()
       logger.info(result)
       return result
   finally:
       conn.close()
