如何从列表到PySpark中的查询获取用逗号分隔的字符串? [英] How to get strings separated by commas from a list to a query in PySpark?

问题描述

我想通过使用PySpark中的列表来生成查询

I want to generate a query by using a list in PySpark

list = ["[e-mail]", "[e-mail]"]
query = "SELECT * FROM table WHERE email IN (" + list + ")"

这是我想要的输出:

query
SELECT * FROM table WHERE email IN ("[e-mail]", "[e-mail]")

相反，我得到:TypeError: cannot concatenate 'str' and 'list' objects

有人可以帮助我实现这一目标吗?谢谢

Can anyone help me achieve this? Thanks

推荐答案

如果某人遇到相同的问题，我发现您可以使用以下代码:

If someone's having the same issue, I found that you can use the following code:

"'"+"','".join(map(str, emails))+"'"

，您将获得以下输出:

SELECT * FROM table WHERE email IN ('[e-mail]', '[e-mail]')
