What is a OLE DB connection?
Object Linking and Embedding Database (OLE DB) is a connectivity method similar to Open Database Connectivity (ODBC) and uses the same core application programming interface (API) to help bridge communication between client applications and a variety of data sources.
How do I find my OLE DB provider?

How do I give OLE DB connection?

What is OLE DB data provider?
The . NET Framework Data Provider for OLE DB (OleDb) 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.
What is OLE DB command?
The OLE DB Command transformation runs an SQL statement for each row in a data flow. For example, you can run an SQL statement that inserts, updates, or deletes rows in a database table.
Which is better OLE DB or ODBC?
ODBC is constrained to relational data stores; OLE DB supports all forms of data stores (relational, hierarchical, etc) In general, OLE DB provides a richer and more flexible interface for data access because it is not tightly bound to a command syntax (like SQL in the case of ODBC).
Is OLE DB faster than ODBC?
2- OLE DB is more faster than ODBC Microsoft ADO, OL DB, and ODBC MDAC Components. Developers can use any of MDAC’s components (ODBC, OLE DB, and ADO) to connect to several relational and non-relational data stores.
What is the difference between Oledb and SQL connection?
The advantage of using OleDbConnection is flexibility. You can change your database (for instance, move to Oracle)and not have to change your code. If you using SQLServer as backend then use SQLConnection for better performance. OleDbConnection : You can connect to any database, which you have provide for that.
How do I know if my Oledb provider is registered?
To find the guid, open regedit and search the registry for the provider name. For example, search for “Microsoft Jet 4.0 OLE DB Provider”. When you find it, copy the key (the GUID value) and use that in a registry search in your application.
Why do we use OLE DB connection?
OLE DB (Object Linking and Embedding, Database, sometimes written as OLEDB or OLE-DB), an API designed by Microsoft, allows accessing data from a variety of sources in a uniform manner. The API provides a set of interfaces implemented using the Component Object Model (COM); it is otherwise unrelated to OLE.
What is OLE DB connection class?
An OleDbConnection object represents a unique connection to a data source. With a client/server database system, it is equivalent to a network connection to the server. Depending on the functionality supported by the native OLE DB provider, some methods or properties of an OleDbConnection object may not be available.
How to create OLEDB connection?
In the Solution Explorer pane,right-click on Connection Managers and select New Connection Manager.
What is OLEDB and ODBC?
ODBC (Open Database Connectivity) and OLEDB (Object Linking and Embedding, Database) are two interfaces that solve this specific problem. ODBC is a platform, language and operating system independent interface that can be used for this purpose. OLEDB is the successor to ODBC.
Who is OLE DB provider?
OLE DB providers are analogous to ODBC drivers, JDBC drivers, and ADO.NET data providers. OLE DB providers can be created to access such simple data stores as a text file and spreadsheet, through to such complex databases as Oracle, Microsoft SQL Server, Sybase ASE , and many others.
What is the Oracle provider for OLE DB?
Oracle Provider for OLE DB (OraOLEDB) is an OLE DB data provider that offers high performance and efficient access to Oracle data by OLE DB consumers. In general, this developer’s guide assumes that you are using OraOLEDB through OLE DB or ADO.
