Microsoft.Data.SqlClient Namespace

Classes

ActiveDirectoryAuthenticationProvider	This class implements SqlAuthenticationProvider and is used for active directory federated authentication mechanisms.
SqlAuthenticationInitializer	Called from constructors in derived classes to initialize the SqlAuthenticationInitializer class.
SqlAuthenticationParameters	Represents AD authentication parameters passed by a driver to authentication providers.
SqlAuthenticationProvider	Defines the core behavior of authentication providers and provides a base class for derived classes.
SqlAuthenticationToken	Represents an AD authentication token.
SqlBulkCopy	Lets you efficiently bulk load a SQL Server table with data from another source.
SqlBulkCopyColumnMapping	Defines the mapping between a column in a SqlBulkCopy instance's data source and a column in the instance's destination table.
SqlBulkCopyColumnMappingCollection	Collection of SqlBulkCopyColumnMapping objects that inherits from CollectionBase.
SqlBulkCopyColumnOrderHint	Defines the sort order for a column in a SqlBulkCopy instance's destination table, according to the clustered index on the table.
SqlBulkCopyColumnOrderHintCollection	Collection of SqlBulkCopyColumnOrderHint objects that inherits from CollectionBase.
SqlClientFactory	Represents a set of methods for creating instances of the Microsoft.Data.SqlClient provider's implementation of the data source classes.
SqlClientLogger	Represents a SQL client logger.
SqlClientMetaDataCollectionNames	Provides a list of constants for use with the GetSchema method to retrieve metadata collections.
SqlColumnEncryptionCertificateStoreProvider	The implementation of the key store provider for Windows Certificate Store. This class enables using certificates stored in the Windows Certificate Store as column master keys. For details, see Always Encrypted.
SqlColumnEncryptionCngProvider	The CMK Store provider implementation for using the Microsoft Cryptography API: Next Generation (CNG) with Always Encrypted.
SqlColumnEncryptionCspProvider	The CMK Store provider implementation for using Microsoft CAPI based Cryptographic Service Providers (CSP) with Always Encrypted.
SqlColumnEncryptionKeyStoreProvider	Base class for all key store providers. A custom provider must derive from this class and override its member functions and then register it using RegisterColumnEncryptionKeyStoreProviders(IDictionary<String,SqlColumnEncryptionKeyStoreProvider>), RegisterColumnEncryptionKeyStoreProvidersOnConnection(IDictionary<String,SqlColumnEncryptionKeyStoreProvider>) or RegisterColumnEncryptionKeyStoreProvidersOnCommand(IDictionary<String,SqlColumnEncryptionKeyStoreProvider>). For details see, Always Encrypted.
SqlCommand	Represents a Transact-SQL statement or stored procedure to execute against a SQL Server database. This class cannot be inherited.
SqlCommandBuilder	Automatically generates single-table commands that are used to reconcile changes made to a DataSet with the associated SQL Server database. This class cannot be inherited.
SqlConfigurableRetryFactory	Provides different retry logic providers with a common list of transient errors.
SqlConnection	Represents a connection to a SQL Server database. This class cannot be inherited.
SqlConnectionEncryptOption	These options are used to control encryption behavior of the communication between the server and the client.
SqlConnectionStringBuilder	Provides a simple way to create and manage the contents of connection strings used by the SqlConnection class.
SqlCredential	SqlCredential provides a more secure way to specify the password for a login attempt using SQL Server Authentication. SqlCredential is comprised of a user id and a password that will be used for SQL Server Authentication. The password in a SqlCredential object is of type SecureString. SqlCredential cannot be inherited. Windows Authentication (Integrated Security = true) remains the most secure way to log in to a SQL Server database.
SqlDataAdapter	Represents a set of data commands and a database connection that are used to fill the DataSet and update a SQL Server database. This class cannot be inherited.
SqlDataReader	Provides a way of reading a forward-only stream of rows from a SQL Server database. This class cannot be inherited.
SqlDependency	The SqlDependency object represents a query notification dependency between an application and an instance of SQL Server. An application can create a SqlDependency object and register to receive notifications via the OnChangeEventHandler event handler.
SqlError	Collects information relevant to a warning or error returned by SQL Server.
SqlErrorCollection	Collects all errors generated by the .NET Framework Data Provider for SQL Server. This class cannot be inherited.
SqlException	The exception that is thrown when SQL Server returns a warning or error. This class cannot be inherited.
SqlInfoMessageEventArgs	Provides data for the InfoMessage event.
SqlNotificationEventArgs	Represents the set of arguments passed to the notification event handler.
SqlParameter	Represents a parameter to a SqlCommand and optionally its mapping to DataSet columns. This class cannot be inherited. For more information on parameters, see Configuring parameters.
SqlParameterCollection	Represents a collection of parameters associated with a SqlCommand and their respective mappings to columns in a DataSet. This class cannot be inherited.
SqlRetryingEventArgs	Represents the set of arguments passed to the Retrying event.
SqlRetryIntervalBaseEnumerator	Generates a sequence of time intervals.
SqlRetryLogicBase	Retrieves the next time interval with respect to the number of retries if a transient condition occurs.
SqlRetryLogicBaseProvider	Applies retry logic on an operation through the Execute or ExecuteAsync function.
SqlRetryLogicOption	Provides the retry logic parameters to create an instance of the SqlRetryLogicBaseProvider class by using SqlConfigurableRetryFactory methods.
SqlRowsCopiedEventArgs	Represents the set of arguments passed to the SqlRowsCopiedEventHandler.
SqlRowUpdatedEventArgs	Provides data for the RowUpdated event.
SqlRowUpdatingEventArgs	Provides data for the RowUpdating event.
SqlTransaction	Represents a Transact-SQL transaction to be made in a SQL Server database. This class cannot be inherited.

Enums

ApplicationIntent	Specifies a value for ApplicationIntent. Possible values are ReadWrite and ReadOnly.
PoolBlockingPeriod	Specifies a value for the PoolBlockingPeriod property.
SortOrder	Specifies how rows of data are sorted.
SqlAuthenticationMethod	Describes the different SQL authentication methods that can be used by a client connecting to Azure SQL Database. For details, see Connecting to SQL Database By Using Azure Active Directory Authentication.
SqlBulkCopyOptions	Bitwise flag that specifies one or more options to use with an instance of SqlBulkCopy.
SqlCommandColumnEncryptionSetting	Note that these settings cannot be used to bypass encryption and gain access to plaintext data. For details, see Always Encrypted (Database Engine).
SqlConnectionAttestationProtocol	Specifies a value for Attestation Protocol.
SqlConnectionColumnEncryptionSetting	Note that these settings cannot be used to bypass encryption and gain access to plaintext data. For details, see Always Encrypted (Database Engine).
SqlConnectionIPAddressPreference	Specifies a value for IP address preference during a TCP connection.
