Pyathena SQL 条件为 Python 的查询

Question

给出以下 python 列表：

customer_list = [123,567,494]

现在我想运行一个 SQL 查询，我在其中使用上面的列表。如何将条件 in (customer_list) 添加到我的查询中？

我试过了：

my_query = """
select * from my_table
where customer in ("""+customer_list")" 
"""
order by name
"""

这给了我错误： TypeError：一元 + 的错误操作数类型：'str'

Answer 1

您可以将查询中的 customer_list 替换为 :

', '.join(str(element) for element in customer_list)

Answer 2

您可以尝试类似的方法：

customer_list = [123,567,494]

my_query = """
select * from my_table
where customer in ({cust_list}) 
order by name
""".format(cust_list=",".join(str(x) for x in customer_list))

输出：

select * from my_table where customer in (123,567,494) order by name
