This also applies to distributed transactions if the session is currently enlisted in a local transaction. Get Emp Records() takes four parameters, only ' two need to be bound because Ref cursor parameters are automatically ' bound by the provider. Create Parameter("Prm1", ad Small Int, ad Param Input, , 30) Cmd. By default, this attribute is set to , Ora OLEDB statement caching is enabled and the value specifies the maximum number of statements that can be cached for a connection.interface, consumers may explicitly start a transaction for a particular session, allowing a unit of work to be explicitly committed or aborted by the consumer. Connection String = "Data Source=My Ora Db;" & _ "User ID=scott; Password=tiger;" Con. After a connection has been cached to the specified maximum cache size, the cursor least recently used is freed to make room to cache the newly-created cursor., which indicates that operating system authentication is not used.

By default, ADO creates a nonupdatable rowset from a command object.

Ora OLEDB consumers must install Oracle Services for Microsoft Transaction Server (MTS) release 10.2 or higher to be able to participate in Microsoft Transaction Server (or COM ) transactions or to enlist in a distributed transaction coordinated by Microsoft Distributed Transaction Coordinator (MS DTC).

Therefore, for running the same statement on different connections, you need to parse once for each connection and cache a separate cursor for each connection.

This method can be useful when the application needs to cancel a long running command during times of heavy network traffic or heavy server use. C/C OLE DB consumers must enable this service to make these rowsets updatable. , only the explicitly provided values for insert and update operations are returned when column values are requested for those rows. However, when new data is submitted to the database, the database only performs the update if the rowset data was not already updated by another user, which means that dirty writes are not allowed. In Visual Basic, date formats are controlled by the Regional Settings properties in Windows Control Panel. In order to perform a fast-load, set the column, the time zone setting of the client is used.
