python-PYODBC ProgrammingError :(“ 42000”,“ [42000] [Microsoft] [Pilote ODBC Microsoft Access]

作者:互联网

我尝试使用另一个mdb上的左联接进行更新查询.

在第一个MDB的游标中,执行以下查询:

update table as ori 
    left join (select * 
               from param in "E:/Jeter/param_141114.mdb" 
               where zone = '1H005') param 
    on ori.dep_sur = param.dsu_co 
set ori.texture = param.textu where mid(ori.type,4,1) in ('0','7','8')

当我从Microsoft Access启动此查询时,没问题,将应用该查询.

当我使用pyodbc从python 2.7启动此查询时,这里的结果是法文翻译的:

ProgrammingError (‘42000’, “[42000] [Microsoft] [ODBC Microsoft Access
Driver] The database engine can not find [E: /Jeter/param_141114.mdb]
‘Make sure the name. parameter or alias is valid, he does not
understand character or incorrect punctuation and that it is not too
long. (-1002) (SQLExecDirectW) “)

有什么想法吗?

解决方法:

显然,SELECT … FROM TableName IN“ FileName” …语法不适用于来自外部应用程序的ODBC查询.但是,我只是尝试了以下变体,并且对我有用(Python 2.7和pyodbc):

sql = """
update tableau as ori 
    left join (select * 
               from [C:/__tmp/test.mdb].param 
               where zone = '1H005') param 
    on ori.dep_sur = param.dsu_co 
set ori.texture = param.textu
"""
crsr = db.execute(sql)
crsr.commit()
