Connect with SQL Server Management Studio

  • Článek

This article describes how to connect to the SQL Server Database Engine with SQL Server Management Studio 20 and later versions, for the following products and services:

  • SQL Server
  • Azure SQL Database
  • Azure SQL Managed Instance
  • Azure Synapse Analytics

Encryption changes

SQL Server Management Studio (SSMS) 20 includes an important security improvement related to connection encryption, and it includes many changes.

  • The Encrypt connection property has been renamed to Encryption.
  • The value of True (Encrypt connection option checked, or enabled) now maps to Mandatory for Encryption.
  • The value of False (Encrypt connection option unchecked, or disabled) now maps to Optional for Encryption.
  • The Encryption property is now set to Mandatory by default.
  • The Encryption property includes a new option, Strict (SQL Server 2022 and Azure SQL), which isn't available in previous versions of SSMS.

In addition, the Encryption and Trust server certificate properties have moved to the Login page under Connection Security. A new option, Host name in certificate, has also been added. The best practice is to support a trusted, encrypted connection to the server.

To encrypt connections, the SQL Server Database Engine must be configured with a TLS certificate signed by a trusted root certificate authority.

For users connecting to Azure SQL Database and Azure SQL Managed Instance, existing connections in the most recently used (MRU) list should be updated to use Strict (SQL Server 2022 and Azure SQL) encryption. Any new connection to Azure SQL Database and Azure SQL Managed Instance should use Strict (SQL Server 2022 and Azure SQL) encryption. Azure SQL Database and Azure SQL Managed Instance support encrypted connections and are configured with trusted certificates.

With Strict (SQL Server 2022 and Azure SQL) encryption selected, the Trust server certificate option is unavailable.

With Mandatory encryption selected, and Trust server certificate enabled (checked), the Host name in certificate option is unavailable.

For users connecting to an on-premises SQL Server or SQL Server in a Virtual Machine, the Database Engine must be configured to support encrypted connections. For complete instructions, see Configure SQL Server Database Engine for encrypting connections.

If the Database Engine has either Force Encryption or Force Strict Encryption enabled, ensure that you have a certificate from a trusted certificate authority. For more information, see Certificate requirements for SQL Server. If you don't have a certificate from a trusted certificate authority and you try to connect, you see the error:

Screenshot of error message when connecting to a SQL Server that doesn't have a certificate from a trusted certificate authority.

The text from the screenshot shows an error similar to the following example:

Cannot connect to MyServer

A connection was successfully established with the server, but then an error occurred during the login process. (provider: SSL Provider, error: 0 - > The certificate chain was issued by an authority that is not trusted.) (Microsoft SQL Server, Error: -2146893019) For help, click: https://docs.microsoft.com/sql/relational-databases/errors-events/mssqlserver--2146893019-database-engine-error

The certificate chain was issued by an authority that is not trusted

For more information, see "The certificate received from the remote server was issued by an untrusted certificate authority" error when you connect to SQL Server.

New connections in SQL Server Management Studio 20 and later versions

For workstations with a new installation of SSMS, or when adding a new connection:

  1. Select Connect in Object Explorer, or File > New > Query with Current Connection.
  2. Within the Connect to Server dialog, set the connection details for your server.

Connection detail description

The following table describes the connection details.

Setting Description
Server name Enter the server name here. For example, MyServer or MyServer\MyInstance or localhost.
Authentication Select the type of authentication to use.
User name Enter the user name with which to authenticate. The user name is automatically populated if Windows Authentication is selected for the Authentication type. When you use Microsoft Entra MFA, the user name can be left blank.
Password Enter the password for the user (if available). The password field is unavailable for specific Authentication types.
*Encryption 1 Select the encryption level for the connection. The default value is Mandatory.
Trust server certificate Check this option to bypass server certificate validation. The default value is False (unchecked), which promotes better security using trusted certificates.
Host name in the certificate The value provided in this option is used to specify a different, but expected, CN or SAN in the server certificate for the server to which SSMS is connecting. This option can be left blank, so that certificate validation ensures that the Common Name (CN) or Subject Alternate Name (SAN) in the certificate matches the server name to which you're connecting. This parameter can be populated when the server name doesn't match the CN or SAN, for example, when using DNS aliases. For more information, see Encryption and certificate validation in Microsoft.Data.SqlClient.

1 The value selected by the user represents the desired and minimal level of encryption. SSMS negotiates with the SQL engine (via the driver) to determine the encryption used, and the connection can be established with a different (yet more secure) level of encryption. For example, if you select Optional for the Encryption option, and the server has Force Encryption enabled and a trusted certificate, then the connection is encrypted.

Connections after upgrading to SQL Server Management Studio 20

During the initial launch of SQL Server Management Studio 20, you're prompted to import settings from an earlier version of SSMS. If you select Import from SSMS 19 or Import from SSMS 18, the list of most recently used connections is imported from the selected version of SSMS.

Screenshot of message asking to import settings.

For workstations that imported settings from SSMS 18 or SSMS 19:

  1. Select Connect in Object Explorer, or File > New > Query with Current Connection.
  2. Within the Connect to Server dialog, select the server to which you want to connect.
  3. Review the options selected for Encryption and Trust server certificate for the existing connection. In some scenarios, it might be necessary to configure a signed certificate or change the value for one or both properties.
  4. If you previously connected with Encryption set to Mandatory, and the SQL Server doesn't have encrypted connections enabled or doesn't have a signed certificate, you're prompted to enable the Trust server certificate option:

Screenshot of prompt asking to enable **Trust Server Certificate** for the connection.

  1. If you select yes, Trust Server Certificate is enabled for the connection. You can also enable Trust Server Certificate for all connections imported from older versions of SSMS.
  2. If you select no, Trust Server Certificate isn't enabled, and you aren't able to connect. Review the configuration to verify that a valid server certificate is installed.

For more information, see Configure SQL Server Database Engine for encrypting connections.

Remarks

These changes are the result of updates at the driver level in Microsoft.Data.SqlClient. Recent releases of Microsoft.Data.SqlClient offer increased security in the connection options. For more information, see Introduction to Microsoft.Data.SqlClient namespace.
