RelationalConnection Class

Definition

Namespace:

Microsoft.EntityFrameworkCore.Storage

Assembly:

Microsoft.EntityFrameworkCore.Relational.dll

Package:

Microsoft.EntityFrameworkCore.Relational v8.0.0

Represents a connection with a relational database.

This type is typically used by database providers (and other extensions). It is generally not used in application code.

Remarks

The service lifetime is Scoped. This means that each DbContext instance will use its own instance of this service. The implementation may depend on other services registered with any lifetime. The implementation does not need to be thread-safe.

See Implementation of database providers and extensions for more information and examples.

Constructors

RelationalConnection(RelationalConnectionDependencies)

Initializes a new instance of the RelationalConnection class.

Properties

CommandTimeout	Gets the timeout for executing a command against the database.
ConnectionId	The unique identifier for this connection.
ConnectionString	Gets or sets the connection string for the database.
Context	The DbContext currently in use.
CurrentAmbientTransaction	The current ambient transaction. Defaults to Current.
CurrentTransaction	Gets the current transaction.
DbConnection	Gets or sets the underlying DbConnection used to connect to the database.
Dependencies	Relational provider-specific dependencies for this service.
EnlistedTransaction	The currently enlisted transaction.
SupportsAmbientTransactions	Indicates whether the store connection supports ambient transactions

Methods

CommitTransaction()	Commits all changes made to the database in the current transaction.
CommitTransactionAsync(CancellationToken)	Commits all changes made to the database in the current transaction.
ConnectionBeginTransaction(IsolationLevel)	Template method that by default calls BeginDbTransaction(IsolationLevel) but can be overridden by providers to make a different call instead.
ConnectionBeginTransactionAsync(IsolationLevel, CancellationToken)	Template method that by default calls BeginDbTransactionAsync(IsolationLevel, CancellationToken) but can be overridden by providers to make a different call instead.
ConnectionEnlistTransaction(Transaction)	Template method that by default calls EnlistTransaction(Transaction) but can be overridden by providers to make a different call instead.
CreateDbConnection()	Creates a DbConnection to the database.
Dispose()	Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
DisposeAsync()	Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
DisposeDbConnection()	Template method that by default calls Dispose() but can be overridden by providers to make a different call instead.
DisposeDbConnectionAsync()	Template method that by default calls DisposeAsync() but can be overridden by providers to make a different call instead.
EnlistTransaction(Transaction)	Specifies an existing Transaction to be used for database operations.
GetValidatedConnectionString()	Returns the configured connection string only if it has been set or a valid DbConnection exists.
Open(Boolean)	Opens the connection to the database.
OpenAsync(CancellationToken, Boolean)	Asynchronously opens the connection to the database.
OpenDbConnection(Boolean)	Template method that by default calls Open() but can be overridden by providers to make a different call instead.
OpenDbConnectionAsync(Boolean, CancellationToken)	Template method that by default calls OpenAsync() but can be overridden by providers to make a different call instead.
RentCommand()	Rents a relational command that can be executed with this connection.
ResetState(Boolean)	Resets the connection state. Called by Dispose() and ResetState().
ResetStateAsync(Boolean)	Resets the connection state. Called by DisposeAsync() and ResetStateAsync(CancellationToken).
ReturnCommand(IRelationalCommand)	Returns a relational command to this connection, so that it can be reused in the future.
RollbackTransaction()	Discards all changes made to the database in the current transaction.
RollbackTransactionAsync(CancellationToken)	Discards all changes made to the database in the current transaction.
SetDbConnection(DbConnection, Boolean)	Sets the underlying DbConnection used to connect to the database.
UseTransaction(DbTransaction)	Specifies an existing DbTransaction to be used for database operations.
UseTransaction(DbTransaction, Guid)	Specifies an existing DbTransaction to be used for database operations.
UseTransactionAsync(DbTransaction, CancellationToken)	Specifies an existing DbTransaction to be used for database operations.
UseTransactionAsync(DbTransaction, Guid, CancellationToken)	Specifies an existing DbTransaction to be used for database operations.
