Question

我的问题是对最初解决的问题的扩展。我对这里的答案没有任何疑问：

我的做法不同：

我有一个非常长的查询，但在我的Jupyter笔记本中看起来不太好。所以，而不是键入它，我试图使用open（'query.sql'）来读取文件。

sql = open(r'H:\Common_All...\query.sql'\).read()

df = pd.read_sql(sql,cxnn)

然后它返回......

ProgrammingError                          Traceback (most recent call last)

   1403             else:
-> 1404                 cur.execute(*args)
   1405             return cur

During handling of the above exception, another exception occurred:

Answer 1

＆＃39; GO＆＃39;
附近的语法不正确

GO不是T-SQL语句。这是一个仅适用于SQL Server shell的命令：sqlcmd，SQL Server Management Studio（SSMS）等。要通过ODBC执行SQL语句，您需要从中删除GO命令你的文字文件。

使用sql脚本将数据从pyodbc移动到pandas
