从 Python 连接到远程桌面上的 MS SQL Server

Question

我正在使用 Windows 服务器通过 VBA 使用以下代码连接到托管在远程桌面上的 SQL Server：

Set objMyConn = New ADODB.Connection
Set objMyCmd = New ADODB.Command
Set objMyRecordset = New ADODB.Recordset

'Open Connection
objMyConn.ConnectionString = "Provider=SQLOLEDB.1;User ID=sa;Password=xxxxx;Persist Security Info=True;Initial Catalog=databaseName;Data Source=192.168.1.xxx;"
objMyConn.Open

目前正在尝试使用 python 通过此代码连接到同一个 SQL Server 数据库：

import pyodbc
server_name='192.168.1.xxx'
db_name='databaseName'
username='sa'
password='xxxxx'
conn = pyodbc.connect('DRIVER={ODBC Driver 11 for SQL Server};'
                      'Server=server_name;'
                      'Database=db_name;' 
                      'UID=username;'
                      'PWD=password;'
                      'Trusted_Connection=yes;')
cursor=conn.cursor()

回溯：

File "x/test.py", line 6, in <module>
    conn = pyodbc.connect('DRIVER={ODBC Driver 11 for SQL Server};'
pyodbc.OperationalError: ('08001', '[08001] [Microsoft][ODBC Driver 11 for SQL Server]Named Pipes Provider: Could not open a connection to SQL Server [53].  (53) (SQLDriverConnect); [08001] [Microsoft][ODBC Driver 11 for SQL Server]Login timeout expired (0); [08001] [Microsoft][ODBC Driver 11 for SQL Server]A network-related or instance-specific error has occurred while establishing a connection to SQL Server. Server is not found or not accessible. Check if instance name is correct and if SQL Server is configured to allow remote connections. For more information see SQL Server Books Online. (53)')

Answer 1

您应该省略参数trusted_connection，因为您提供的是 UID 和 PWD。 Trusted_connection 用您当前的 windows 用户值填充 UID 和 PWD 值，因此它可能保留用于主机内的本地连接。 我相信连接字符串应该是这样的：

'DRIVER={ODBC Driver 11 for SQL Server};'
                      'Server=server_name;'
                      'Database=db_name;' 
                      'UID=username;'
                      'PWD=password;'
