When TrustServerCertificate is set to true, the transport layer uses TLS/SSL to encrypt the channel and bypass walking the certificate chain to validate trust. The TrustServerCertificate keyword is used when connecting to a SQL Server instance.

A user instance executes with the user's Windows credentials, not as a service.įor more information on working with user instances, see SQL Server Express User Instances. They allow a user running on a least-privileged local Windows account to attach and run a SQL Server database without requiring administrative privileges. User instances are a feature in SQL Server Express. Connect and Attach to SQL Server Express user instances For more information about the Type System Version keyword, see SqlConnection.ConnectionString. The Type System Version keyword in a SqlConnection.ConnectionString specifies the client-side representation of SQL Server types. The DataSource property of a SqlConnection object is read-only. You can also set the DataSource property of the SqlConnectionStringBuilder to the instance name when building a connection string. To connect to a named instance of SQL Server, use the server name\instance name syntax. Connect to a named instance of SQL Server

If you specify both Integrated Security=true as well as a user name and password, the user name and password will be ignored and Windows authentication will be used. Windows authentication takes precedence over SQL Server logins. When you connect to Azure SQL Database or to Azure Synapse Analytics and provide a username in the format make sure that the servername value in the username matches the value provided for Server=. "Persist Security Info=False User ID=***** Password=***** Initial Catalog=AdventureWorks Server=MySqlServer Encrypt=True " In this example, asterisks are used to represent a valid user name and password. However, if SQL Server Authentication is required, use the following syntax to specify a user name and password. Windows Authentication is preferred for connecting to SQL Server. "Persist Security Info=False Trusted_Connection=True "Persist Security Info=False Integrated Security=SSPI ĭatabase=AdventureWorks server=(local) Encrypt=True " Initial Catalog=AdventureWorks Server=MSSQL1 Encrypt=True "

"Persist Security Info=False Integrated Security=true Windows authentication with SqlClientĮach of the following forms of syntax uses Windows Authentication to connect to the AdventureWorks database on a local server. Keep Persist Security Info set to false to ensure that an untrusted source does not have access to sensitive connection string information. Setting it to true or yes allows security-sensitive information, including the user ID and password, to be obtained from the connection after the connection has been opened. The default setting for the Persist Security Info keyword is false. The connection string keywords also map to properties in the SqlConnectionStringBuilder. You can use the ConnectionString property to get or set a connection string for a SQL Server database.

The syntax for a SqlConnection connection string is documented in the SqlConnection.ConnectionString property. The following table shows the Windows Authentication syntax used with the Microsoft SqlClient Data Provider for SQL Server. We recommend using Windows Authentication (sometimes referred to as integrated security) to connect to data sources that support it. For more information, see Connection String Builders. The connection string builders allow you to construct syntactically valid connection strings at run time, so you don't have to manually concatenate connection string values in your code. Microsoft SqlClient Data Provider for SQL Server introduced the following connection string builder. For more information on connection string syntax, see ConnectionString. The specific connection string syntax for the SqlClient provider is documented in its ConnectionString property. \SQL2016 or (local)\SQL2016 or localhost\SQL2016 as the server/instance name (defined by the server= or data source= settings in the connection string).The has a Connection object that inherits from DbConnection and a provider-specific ConnectionString property. In that case, your connection string will need to use. If you have SQL Server 2014 as your default instance (with no instance name needed to connect to it - that's the MSSQLSERVER "instance", but that name must not be used in the connection string!), then you must use a separate, different instance name for your SQL Server 2016 installation, e.g.
