This method updates the object referenced by the specified REF
in the database using the specified custom object.
Declaration
// C# public void Update(object customObject, bool bFlush);
Parameters
customObject
The custom object used to update the referenced object.
bFlush
A boolean that specifies if the changes must be flushed immediately. If bFlush
is set to true, this method invocation flushes the changes immediately.
Exceptions
InvalidOperationException
- The specified connection is not open or the custom object does not map to the type of referenced object.
Remarks
This method marks the specified REF
for update. Depending on whether the value of bFlush
is set to true or false, the following occurs:
True
The object referenced by the specified REF
is updated immediately in the database.
Before flushing objects, it is required that the application has explicitly started a transaction by executing the BeginTransaction
method on the OracleConnection
object. This is because if the object being flushed has not already been locked by the application, an exclusive lock is obtained implicitly for the object. The lock is only released when the transaction commits or rollbacks.
False
The object referenced by the REF
is not updated immediately in the database, but only when a subsequent Flush
method is invoked for the specified REF
or the FlushCache
method is invoked for the specified connection.
The connection must be opened explicitly by the application. This method does not open the connection implicitly.
