OracleCommand.Cancel Method ()
Attempts to cancel the execution of an OracleCommand.
Assembly: System.Data.OracleClient (in System.Data.OracleClient.dll)
If there is nothing to cancel, nothing happens. However, if there is a command in process, and the attempt to cancel fails, no exception is generated.
The following example creates an OracleCommand, executes it, then cancels the execution. To accomplish this, the method is passed a string that is an SQL SELECT statement and a string to use to connect to the database.
Public Sub CreateOracleCommand _ (ByVal queryString As String, ByVal connectionString As String) Using connection As New OracleConnection(connectionString) Dim command As New OracleCommand(queryString, connection) command.Connection.Open() command.ExecuteReader() command.Cancel() End Using End Sub
