[英]Issue connecting to SQL Server using DBI:dbConnect in R
The first method I tried works. 我尝试的第一种方法有效。 I first defined an ODBC connection
my_connection_name
with ODBC data source administrator
on my windows. 我首先在Windows上与
ODBC data source administrator
定义了ODBC连接my_connection_name
。 Then I use the following code: 然后,我使用以下代码:
library(DBI)
library(odbc)
con <- DBI::dbConnect(odbc(),
dsn='my_connection_name',
UID = "firstname.lastname@company.com",
PWD = "mypassword")
This works fine! 这样很好!
However, when I tried to define the driver, server and database name within the dbConnect
function. 但是,当我尝试在
dbConnect
函数中定义驱动程序,服务器和数据库名称时。 It fails! 它失败!
con <- DBI::dbConnect(odbc(),
Driver = "ODBC Driver 13 for SQL Server",
Server = 'my_server_name',
Database = "my_database_name",
UID = "firstname.lastname@company.com",
PWD = "mypassword",
Trusted_Connection = "yes")
I got error: 我收到错误消息:
Error: nanodbc/nanodbc.cpp:950: 08S01: [Microsoft][ODBC Driver 13 for SQL Server]TCP Provider: An existing connection was forcibly closed by the remote host.
Interestingly, when I remove the Trusted_Connection = "yes"
. 有趣的是,当我删除
Trusted_Connection = "yes"
。
con <- DBI::dbConnect(odbc(),
Driver = "ODBC Driver 13 for SQL Server",
Server = 'my_server_name',
Database = "my_database_name",
UID = "firstname.lastname@company.com",
PWD = "mypassword")
I got error message like this: 我收到这样的错误消息:
Error: nanodbc/nanodbc.cpp:950: HY000: [Microsoft][ODBC Driver 13 for SQL Server][SQL Server]Cannot open server "company.com" requested by the login.
错误:nanodbc / nanodbc.cpp:950:HY000:[Microsoft] [用于SQL Server的ODBC驱动程序13] [SQL Server]无法打开登录请求的服务器“ company.com”。 The login failed.
登录失败。
I used the same driver, server and database name when I defined the ODBC connection previously. 之前定义ODBC连接时,我使用了相同的驱动程序,服务器和数据库名称。
My authentication option is ActiveDirectoryPassword
. 我的身份验证选项是
ActiveDirectoryPassword
。
Does anyone know what is going on? 有人知道发生了什么吗?
if using Trusted Connection = Yes, you don't need to supply your username and password. 如果使用Trusted Connection =是,则无需提供用户名和密码。 your service account will be used to connect to your sql server.
您的服务帐户将用于连接到SQL Server。
con <- DBI::dbConnect(odbc(),
Driver = "ODBC Driver 13 for SQL Server",
Server = 'my_server_name',
Database = "my_database_name",
Trusted_Connection = "yes")
