Properties

AccessToken (Inherited from ConnectionSettings)
ApplicationIntent

The application intent of the connection Valid values are ReadWrite and ReadOnly

(Inherited from ConnectionSettings)
ApplicationName

The name of the application. 'SQL Management' if no application name has been provided. Exceptions: ConnectionCannotBeChangedException InvalidPropertyValueException

(Inherited from ConnectionSettings)
Authentication

The authentication type of the connection

(Inherited from ConnectionSettings)
AutoDisconnectMode
CapturedSql
ConnectAsUser

If set to true, the connection will be made with the credentials of the specified user. This will assume impersonation, however the LoginSecure flags and Login and Password fields will not be affected. ConnectionCannotBeChangedException

(Inherited from ConnectionSettings)
ConnectAsUserName

Specifies the NT user that is used when creating an impersonated connection. Exceptions: ConnectionCannotBeChangedException InvalidPropertyValueException PropertyNotSetException

(Inherited from ConnectionSettings)
ConnectAsUserPassword

Specifies password of the NT user that is used when creating an impersonated connection. Exceptions: ConnectionCannotBeChangedException InvalidPropertyValueException PropertyNotSetException

(Inherited from ConnectionSettings)
ConnectionProtocol

Connection protocol.

ConnectionString

The property will return either the user specified connection string or it will return the computed connection string based on object settings. If explicitly set, All properties in the ServerConnection object will be populated to reflect the passed in connection string. Exceptions: ConnectionCannotBeChangedException InvalidPropertyValueException

(Inherited from ConnectionSettings)
ConnectTimeout

The length of time (in seconds) to wait for a connection to the server before terminating the attempt and throwing an exception. Default is 30 seconds (same as Shiloh). Exceptions: ConnectionCannotBeChangedException InvalidPropertyValueException

(Inherited from ConnectionSettings)
CurrentDatabase

Returns the current database context.

DatabaseEngineEdition

The edition of the Database Engine

DatabaseEngineType

Returns the database engine type of SQL Server. Exceptions: ConnectionFailureException

DatabaseName

TBD

(Inherited from ConnectionSettings)
EncryptConnection

whether "encrypt=true" is specified in the connection string

(Inherited from ConnectionSettings)
HostPlatform

The host platform of the server (Linux/Windows/etc)

InUse

Returns true if the object has been connected with the server at least once. If true, property changes are not allowed any more and ConnectionCannotBeChangedException will be thrown when a property has been changed.

IsContainedAuthentication

Returns true if the database engine authenticates using contained authentication. Exceptions: ConnectionFailureException

IsForceDisconnected

Indicates that the connection has been forcefully disconnected

IsOpen

Returns true if the SqlConnection object is connected with the server. This can only return true for non pooled connections as pooled connections are always closed directly after an operation.

LockTimeout

LockTimeout is the Lock timeout in seconds. Default -1 is for indefinite. InvalidPropertyValueException is thrown for all other negative numbers. Positive LockTimeout will be multiplied by 1000 and then used for "SET LOCK_TIMEOUT" setting.

Login

The SQL Server Login name that is used to connect to the server. Exceptions: ConnectionCannotBeChangedException InvalidPropertyValueException PropertyNotSetException

(Inherited from ConnectionSettings)
LoginSecure

If set to true, Windows integrate security is used and Login and Password are ignored. If not set, Sql Server Authentication is used. Exceptions: ConnectionCannotBeChangedException

(Inherited from ConnectionSettings)
MaxPoolSize

The maximum number of connections allowed in the pool. Exceptions: ConnectionCannotBeChangedException InvalidPropertyValueException

(Inherited from ConnectionSettings)
MinPoolSize

The minimum number of connections maintained in the pool. Exceptions: ConnectionCannotBeChangedException InvalidPropertyValueException

(Inherited from ConnectionSettings)
MultipleActiveResultSets

Enable MARS from the connection. Default is false.

(Inherited from ConnectionSettings)
NetworkProtocol

Identifies the client network protocol that is used to connect to SQL Server. If you do not specify a network and you use a local server, shared memory is used. If you do not specify a network and you use a remote server, the one of the configured client protocols is used. Exceptions: ConnectionCannotBeChangedException InvalidPropertyValueException

(Inherited from ConnectionSettings)
NonPooledConnection

By default, all connections to SQL Server are taken from an ADO.NET connection pool.If set to true, this allows users to create a non-pooled connection (will not be reused when closed). Exceptions: ConnectionCannotBeChangedException

(Inherited from ConnectionSettings)
PacketSize

Size in bytes of the network packets used to communicate with an instance of SQL Server. Default is 8192. Exceptions: ConnectionCannotBeChangedException InvalidPropertyValueException

(Inherited from ConnectionSettings)
Password

The password that is used with Login to connect to the server. Exceptions: ConnectionCannotBeChangedException InvalidPropertyValueException PropertyNotSetException

(Inherited from ConnectionSettings)
PooledConnectionLifetime

When a connection is returned to the pool, its creation time is compared with the current time, and the connection is destroyed if that time span (in seconds) exceeds the value specified by connection lifetime. Exceptions: ConnectionCannotBeChangedException InvalidPropertyValueException

(Inherited from ConnectionSettings)
ProductVersion

Gets the ProductVersion server property of this connection

ResetConnectionString

Tells us whether ConnectionString needs to be reset in SqlConnectionObject property of ConnectionManager or not.

(Inherited from ConnectionSettings)

SqlConnectionObject

Returns a reference to the SqlConnection object used by the ConnectionContext object. This should always return the valid sqlConnection object with the latest valid ConnectionString set. Exceptions: PropertyNotAvailableException

TrustServerCertificate

Indicate whether the client trusts the server certificate

(Inherited from ConnectionSettings)
WorkstationId

The name of the workstation connecting to SQL Server. Exceptions: ConnectionCannotBeChangedException InvalidPropertyValueException
