python - PYODBC--未找到数据源名称且未指定默认驱动程序

Question

import pyodbc
connection = pyodbc.connect('Driver = {SQL Server};Server=SIWSQL43A\SIMSSPROD43A;'
                            'Database=CSM_reporting;Trusted_Connection=yes;')

错误:

connection = pyodbc.connect('Driver = {SQL Server};Server=SIWSQL43A\SIMSSPROD43A;'
    pyodbc.Error: ('IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified (0) (SQLDriverConnect)')

Answer 1

不要在连接字符串中的 Driver 关键字后放置空格。

这在 Windows 上失败了......

conn_str = (
    r'DRIVER = {SQL Server};'
    r'SERVER=(local)\SQLEXPRESS;'
    r'DATABASE=myDb;'
    r'Trusted_Connection=yes;'
)
cnxn = pyodbc.connect(conn_str)

...但这有效:

conn_str = (
    r'DRIVER={SQL Server};'
    r'SERVER=(local)\SQLEXPRESS;'
    r'DATABASE=myDb;'
    r'Trusted_Connection=yes;'
)
cnxn = pyodbc.connect(conn_str)
