阿里云 MaxCompute通过python脚本调用odps流程和执行sql

1、python脚本调用odps流程

• 如果平台python版本比较低，会无法使用run_script方法，目前作者没有找到解决的办法

  from odps import ODPS
  
  # 创建 ODPS 对象，如果该脚本是在阿里云DataWorks上运行的，下面4句可删了
  access_id = '<your-access-id>'
  access_key = '<your-access-key>'
  project_name = '<your-project-name>'
  odps = ODPS(access_id, access_key, project_name)
  
  # 指定脚本名称
  script_name = 'my_script'
  
  # 定义参数
  params = {
      '@param1': 'value1',
      '@param2': 'value2'
  }
  
  # 调用 ODPS Script
  instance = odps.run_script(script_name, params=params)
  instance.wait_for_success()
  
  # 获取查询结果
  with instance.open_reader() as reader:
      for record in reader:
          print(record)

2、python脚本调用执行sql

from odps import ODPS

# 创建 ODPS 对象，如果该脚本是在阿里云DataWorks上运行的，下面4句可删了
access_id = '<your-access-id>'
access_key = '<your-access-key>'
project_name = '<your-project-name>'
odps = ODPS(access_id, access_key, project_name)

# 定义参数
param1 = 'value1'
param2 = 'value2'

# 动态构建 SQL 语句
sql = f"SELECT * FROM my_table WHERE column1 = '{param1}' AND column2 = '{param2}'"

# 执行 SQL
instance = odps.run_sql(sql)
instance.wait_for_success()

# 获取查询结果
with instance.open_reader() as reader:
    for record in reader:
        print(record)
