如何将逗号分隔的字符串从列表中获取到 PySpark 中的查询? [英] How to get strings separated by commas from a list to a query in PySpark?

问题描述

我想使用 PySpark 中的列表生成查询

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

谁能帮我实现这个目标?谢谢

Can anyone help me achieve this? Thanks

推荐答案

如果有人遇到同样的问题，我发现你可以使用以下代码:

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]')
