IRelationalConnection Interface

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.

public interface IRelationalConnection : IAsyncDisposable, IDisposable, Microsoft.EntityFrameworkCore.Storage.IDbContextTransactionManager, Microsoft.EntityFrameworkCore.Storage.IRelationalTransactionManager

type IRelationalConnection = interface
    interface IRelationalTransactionManager
    interface IDbContextTransactionManager
    interface IResettableService
    interface IDisposable
    interface IAsyncDisposable

Public Interface IRelationalConnection
Implements IAsyncDisposable, IDbContextTransactionManager, IDisposable, IRelationalTransactionManager

Derived

Microsoft.EntityFrameworkCore.Storage.RelationalConnection

Implements

IDbContextTransactionManager IRelationalTransactionManager IDisposable IResettableService IAsyncDisposable

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.

Properties

CommandTimeout	Gets the timeout for executing a command against the database.
ConnectionId	Gets the connection identifier.
ConnectionString	Gets or sets the connection string for the database.
Context	The DbContext currently in use, or null if not known.
CurrentTransaction	Gets the current transaction.
DbConnection	Gets or sets the underlying DbConnection used to connect to the database.

Methods

BeginTransaction()	Begins a new transaction. (Inherited from IDbContextTransactionManager)
BeginTransaction(IsolationLevel)	Begins a new transaction. (Inherited from IRelationalTransactionManager)
BeginTransactionAsync(CancellationToken)	Asynchronously begins a new transaction. (Inherited from IDbContextTransactionManager)
BeginTransactionAsync(IsolationLevel, CancellationToken)	Asynchronously begins a new transaction. (Inherited from IRelationalTransactionManager)
Close()	Closes the connection to the database.
CloseAsync()	Closes the connection to the database.
CommitTransaction()	Commits all changes made to the database in the current transaction. (Inherited from IDbContextTransactionManager)
CommitTransactionAsync(CancellationToken)	Commits all changes made to the database in the current transaction. (Inherited from IDbContextTransactionManager)
Open(Boolean)	Opens the connection to the database.
OpenAsync(CancellationToken, Boolean)	Asynchronously opens the connection to the database.
RentCommand()	Rents a relational command that can be executed with this connection.
ResetState()	Resets the service so that it can be used from the pool. (Inherited from IResettableService)
ResetStateAsync(CancellationToken)	Resets the service so that it can be used from the pool. (Inherited from IResettableService)
ReturnCommand(IRelationalCommand)	Returns a relational command to this connection, so that it can be reused in the future.

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. (Inherited from IRelationalTransactionManager)
UseTransaction(DbTransaction, Guid)	Specifies an existing DbTransaction to be used for database operations. (Inherited from IRelationalTransactionManager)
UseTransactionAsync(DbTransaction, CancellationToken)	Specifies an existing DbTransaction to be used for database operations. (Inherited from IRelationalTransactionManager)
UseTransactionAsync(DbTransaction, Guid, CancellationToken)	Specifies an existing DbTransaction to be used for database operations. (Inherited from IRelationalTransactionManager)
