I'm getting this error when running Update-Database command from package manager console:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SNI_PN11, error: 25 - Connection string is not valid).
The connection string I have used is:
"ConnectionStrings": {
"CarConnectionString": "server=servername\\SQLEXPRESS, database=CarModel, Trusted_connection=true"
}
Any help, suggestions will be highly appreciated
Thanks for the suggestions in the comments.
The correct connection string is:
"ConnectionStrings": {
"CarConnectionString": "server=server\\SQLEXPRESS, 1433; database= CarModel; Trusted_connection=true"
}
I am trying to connect to an Azure SQL Server Database from R, so I can create a table and upload data to the database.
This is how I connect to the server in SQL Server Management Studio
I have tried the following:
library(odbc)
con <- dbConnect(odbc(),
Driver = "SQL Server",
Server = "server_name, 1433",
Database = "database_name",
uid = "me#domain.com",
pwd = "password")
This results in the error:
Error: nanodbc/nanodbc.cpp:1021: HY000: [Microsoft][ODBC SQL Server Driver][SQL Server]Cannot open server "domain.com" requested by the login. The login failed.
library(RODBC)
con.text <- paste("DRIVER={"SQL Server"}",
";Database=database_name",
";Server=server_name",
",1433",
";PROTOCOL=TCPIP",
";trusted_connection=true",
sep="")
con <- odbcDriverConnect(con.text)
This results in the warning messages:
1: In odbcDriverConnect(con.text) :
[RODBC] ERROR: state HY000, code 40607, message [Microsoft][ODBC SQL Server Driver][SQL Server]Windows logins are not supported in this version of SQL Server.
2: In odbcDriverConnect(con.text) :
[RODBC] ERROR: state 01S00, code 0, message [Microsoft][ODBC SQL Server Driver]Invalid connection string attribute
3: In odbcDriverConnect(con.text) : ODBC connection failed
How can I successfully connect to this server from R?
Error: nanodbc/nanodbc.cpp:1021: HY000: [Microsoft][ODBC SQL Server
Driver][SQL Server]Cannot open server "domain.com" requested by the
login. The login failed.
The above error is mainly caused because of driver problem. Use this command to check whether drivers are properly installed or not.
library(odbc)
sort(unique(odbcListDrivers()[[1]]))
Connect Azure SQL database from R ,follow this Syntax:
library(odbc)
library(DBI)
library(RODBC)
con <- DBI::dbConnect(odbc::odbc(),
Driver = "[your driver's name]",
Server = "[your server's path]",
Database = "[your database's name]",
UID = "Database user",
PWD = "Database password",
Port = 1433)
Please follow the below reference it has detailed information about connecting Azure SQL to R in a detailed way:

Why is the driver complaining that the server does not support SSL?
Our Biztalk (2006R2) faced an error as below:
Error 1

Description:
An error occurred while attempting to access the SSO database.

A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - The specified network name is no longer available.).
SQL Error code: 0x00000040

Error2
The following stored procedure call failed: " { call admsvr_ReceiveLocation_GetAllInApp( ?)}". SQL Server returned error string: "[DBNETLIB][ConnectionRead (recv()).]General network error. Check your network documentation.".
But we cannot find any error in SQL Server event log and SQL Server log.
Is there any idea on the possible cause of this error?
Thanks.
I'm doing a simple check if user is in role Administrator to show an item in the Navigation:
#if (User.IsInRole("Administrator"))
{
<li>#Html.ActionLink("Edit categories", "Index", "Category", new { area = "Administration" }, null)</li>
}
... and I got this error:
A network-related or instance-specific error occurred while
establishing a connection to SQL Server. The server was not found or
was not accessible. Verify that the instance name is correct and that
SQL Server is configured to allow remote connections. (provider: SQL
Network Interfaces, error: 26 - Error Locating Server/Instance

Any workaround?
