Question

我的代码如下所示：

pip install pandasql

import pandasql as pdsql

str1="select * from data5 limit 5;" 


df11=pdsql.sqldf(str1)

但是，我收到此错误消息：

Error:

AttributeError: 'tuple' object has no attribute 'filename'

Answer 1

试试这个：

import pandasql as pdsql

pysqldf = lambda q: sqldf(q, globals()) res = pysqldf(your_query)

我希望它有所帮助。

在python 2中使用sqldf，收到错误
