Connection Object
The ADO Connection Object is used to create an open connection to a data source.Through thisconnection, you can access and manipulatea database.
If you want to access a database multiple times, you should establish a connection using the Connection object.You can also make a connection to a database by passing a connection string via a Command or Recordset object. However,this type of connection is only good for one specific, single query.
ProgID

ADO Connection Object
The ADO Connection Object is used to create an open connection to a data source. It allows you to access and manipulate a database. If you want to access a database multiple times, it is recommended to establish a connection using the Connection object. You can also make a connection to a database by passing a connection string via a Command or Recordset object. However, this type of connection is only good for one specific, single query.
The ADO Connection Object has various properties and methods that can be used to configure and interact with the connection. Here are some of the important properties and methods:
Properties:
- Attributes: Sets or returns the attributes of a Connection object.
- CommandTimeout: Sets or returns the number of seconds to wait while attempting to execute a command.
- ConnectionString: Sets or returns the details used to create a connection to a data source.
- ConnectionTimeout: Sets or returns the number of seconds to wait for a connection to open.
- CursorLocation: Sets or returns the location of the cursor service.
- DefaultDatabase: Sets or returns the default database name.
- IsolationLevel: Sets or returns the isolation level.
- Mode: Sets or returns the provider access permission.
- Provider: Sets or returns the provider name.
- State: Returns a value describing if the connection is open or closed.
- Version: Returns the ADO version number.
Methods:
- BeginTrans: Begins a new transaction.
- Cancel: Cancels an execution.
- Close: Closes a connection.
- CommitTrans: Saves any changes and ends the current transaction.
- Execute: Executes a query, statement, procedure, or provider-specific text.
- Open: Opens a connection.
- OpenSchema: Returns schema information from the provider about the data source.
- RollbackTrans: Cancels any changes in the current transaction and ends the transaction.
The ADO Connection Object also has events and collections associated with it, such as the Events collection and the Errors and Properties collections.
