Mdac 6. 1. 7601NET Framework Data Providers Microsoft Docs. A. NET Framework data provider is used for connecting to a database, executing commands, and retrieving results. Those results are either processed directly, placed in a Data. Set in order to be exposed to the user as needed, combined with data from multiple sources, or remoted between tiers. NET Framework data providers are lightweight, creating a minimal layer between the data source and code, increasing performance without sacrificing functionality.

NET Framework Data Providers The following table outlines the four core objects that make up a. NET Framework data provider. Object. Description. Mdac 6. 3Connection. Establishes a connection to a specific data source. The base class for all Connection objects is the Db. Connection class. Command. Executes a command against a data source. Exposes Parameters and can execute in the scope of a Transaction from a Connection. The base class for all Command objects is the Db. Command class. Data. Reader. Reads a forward only, read only stream of data from a data source. The base class for all Data. Reader objects is the Db. D0%93%D1%80%D0%B0%D1%84%D0%B8%D0%BA+%D0%BF%D1%80%D0%BE%D0%B3%D1%80%D0%B0%D0%BC%D0%BC%D1%8B/1582/' alt='Mdac 6' title='Mdac 6' />Data. Reader class. Data. Adapter. Populates a Data. Set and resolves updates with the data source. The base class for all Data. Adapter objects is the Db. Data. Adapter class. In addition to the core classes listed in the table earlier in this document, a. NET Framework data provider also contains the classes listed in the following table. Object. Description. Transaction. Enlists commands in transactions at the data source. The base class for all Transaction objects is the Db. Transaction class. ADO. NET also provides support for transactions using classes in the System. Transactions namespace. Command. Builder. A helper object that automatically generates command properties of a Data. Adapter or derives parameter information from a stored procedure and populates the Parameters collection of a Command object. The base class for all Command. Builder objects is the Db. Command. Builder class. Connection. String. Builder. A helper object that provides a simple way to create and manage the contents of connection strings used by the Connection objects. The base class for all Connection. String. Builder objects is the Db. Connection. String. Builder class. Parameter. Defines input, output, and return value parameters for commands and stored procedures. The base class for all Parameter objects is the Db. Parameter class. Exception. Returned when an error is encountered at the data source. For an error encountered at the client,. NET Framework data providers throw a. NET Framework exception. The base class for all Exception objects is the Db. Exception class. Error. Exposes the information from a warning or error returned by a data source. Client. Permission. Provided for. NET Framework data provider code access security attributes. The base class for all Client. Permission objects is the DBData. Permission class. NET Framework Data Provider for SQL Server Sql. Client The. NET Framework Data Provider for SQL Server Sql. Client uses its own protocol to communicate with SQL Server. It is lightweight and performs well because it is optimized to access a SQL Server directly without adding an OLE DB or Open Database Connectivity ODBC layer. The following illustration contrasts the. NET Framework Data Provider for SQL Server with the. NET Framework Data Provider for OLE DB. The. NET Framework Data Provider for OLE DB communicates to an OLE DB data source through both the OLE DB Service component, which provides connection pooling and transaction services, and the OLE DB provider for the data source. Note The. NET Framework Data Provider for ODBC has a similar architecture to the. NET Framework Data Provider for OLE DB for example, it calls into an ODBC Service Component. Comparison of the. NET Framework Data Provider for SQL Server and the. NET Framework Data Provider for OLE DB The. NET Framework Data Provider for SQL Server classes are located in the System. Data. Sql. Client namespace. The. NET Framework Data Provider for SQL Server supports both local and distributed transactions. For distributed transactions, the. NET Framework Data Provider for SQL Server, by default, automatically enlists in a transaction and obtains transaction details from Windows Component Services or System. Transactions. For more information, see Transactions and Concurrency. The following code example shows how to include the System. Data. Sql. Client namespace in your applications. Imports System. Data. Sql. Client. using System. Data. Sql. Client. NET Framework Data Provider for OLE DB The. NET Framework Data Provider for OLE DB Ole. Db uses native OLE DB through COM interop to enable data access. The. NET Framework Data Provider for OLE DB supports both local and distributed transactions. For distributed transactions, the. NET Framework Data Provider for OLE DB, by default, automatically enlists in a transaction and obtains transaction details from Windows Component Services. For more information, see Transactions and Concurrency. The following table shows the providers that have been tested with ADO. NET. Driver. Provider. SQLOLEDBMicrosoft OLE DB provider for SQL Server. MSDAORAMicrosoft OLE DB provider for Oracle. Microsoft. Jet. OLEDB. OLE DB provider for Microsoft Jet. Note Using an Access Jet database as a data source for multithreaded applications, such as ASP. NET applications, is not recommended. If you must use Jet as a data source for an ASP. NET application, realize that ASP. NET applications connecting to an Access database can encounter connection problems. The. NET Framework Data Provider for OLE DB does not support OLE DB version 2. OLE DB Providers that require support for OLE DB 2. NET Framework Data Provider for OLE DB. This includes the Microsoft OLE DB provider for Exchange and the Microsoft OLE DB provider for Internet Publishing. The. NET Framework Data Provider for OLE DB does not work with the OLE DB provider for ODBC MSDASQL. To access an ODBC data source using ADO. NET, use the. NET Framework Data Provider for ODBC. NET Framework Data Provider for OLE DB classes are located in the System. Data. Ole. Db namespace. The following code example shows how to include the System. Data. Ole. Db namespace in your applications. Corel Draw X6 Free Tutorials. Imports System. Data. Ole. Db. using System. Data. Ole. Db. NET Framework Data Provider for ODBC The. NET Framework Data Provider for ODBC Odbc uses the native ODBC Driver Manager DM to enable data access.
