要创建查询，您可以执行以下操作：

import pandas as pd
df = pd.DataFrame(['abc', 'bce'], columns=['users'])
df
>>>   users
>>> 0   abc
>>> 1   bce

query = "SELECT * FROM users WHERE user_id in (%s)" % ','.join(df['users'])
>>> 'SELECT * FROM users WHERE user_id in (abc,bce)'
query = "SELECT * FROM users WHERE user_id in ('%s')" % "','".join(df['users'])
>>> "SELECT * FROM users WHERE user_id in ('abc','bce')"
