python - "Execution failed on sql"用于使用 pandas.read_sql 和 MSAccess 的特定表名

Question

最奇怪的事情正在发生。我在 Python 2.7 32 位中使用 pypyodbc 和 pandas.io.sql 连接到 Access DB。以下代码可以完美地处理任何表名 (table_name):

var = psql.read_sql("SELECT * FROM table_name;",conn)

除了名为Currency 的表。我什至可以调用表 Currenc 并且代码可以正常工作，没问题。在末尾添加 y 后，我得到:

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Python27\lib\site-packages\pandas\io\sql.py", line 421, in read_sql

File "C:\Python27\lib\site-packages\pypyodbc.py", line 954, in ctrl_err
raise ProgrammingError(state,err_text)
pandas.io.sql.DatabaseError: Execution failed on sql: SELECT * FROM Currency;

有什么想法吗？

谢谢

Currency 是 reserved word在 Access SQL 中，因此如果需要将其用作表(或列)名称，则必须将其括在方括号中，即

SELECT ... FROM [Currency]
