我已使用以下代码从python代码创建dsn。
import ctypes
ODBC_ADD_DSN = 1 # Add data source
ODBC_CONFIG_DSN = 2 # Configure (edit) data source
ODBC_REMOVE_DSN = 3 # Remove data source
ODBC_ADD_SYS_DSN = 4 # add a system DSN
ODBC_CONFIG_SYS_DSN = 5 # Configure a system DSN
ODBC_REMOVE_SYS_DSN = 6 # remove a system DSN
def create_sys_dsn(driver, **kw):
"""Create a system DSN
Parameters:
driver - ODBC driver name
kw - Driver attributes
Returns:
0 - DSN not created
1 - DSN created
"""
nul = chr(0)
attributes = []
for attr in kw.keys():
attributes.append("%s=%s" % (attr, kw[attr]))
return ctypes.windll.ODBCCP32.SQLConfigDataSource(0, ODBC_ADD_SYS_DSN, driver, nul.join(attributes))
if __name__ == "__main__":
if create_sys_dsn("SQL Server",SERVER="(localhost)", DESCRIPTION="Northwind SQL Server DSN", DSN="NorthwindDSN", Database="Northwind", Trusted_Connection="Yes"):
print ("DSN created")
else:
print ("DSN not created")
但是我面临以下错误:-
回溯(最近通话最近): 在第27行的文件“ testDB.py”中 如果create_sys_dsn(“ SQL Server”,SERVER =“(localhost)”,description =“ Northwind SQL Server DSN”,DSN =“ NorthwindDSN”,Database =“ Northwind”,Trusted_Connection =“ Yes”): create_sys_dsn中的文件“ testDB.py”,第24行 返回ctypes.windll.ODBCCP32.SQLConfigDataSource(0,ODBC_ADD_SYS_DSN,驱动程序,nul.join(属性)) ctypes.ArgumentError:参数4::嵌入空字符
谁能帮我解决这个问题。
