The fastest way for Oracle to locate a record is by specifying the ROWID in a Where clause. Consider using ROWIDs when configuring your application to work with the OracleDataAdapter object. By including ROWID in the Select list for the Select command, you can leverage it in your Where clause for your Update and Delete commands. If you are using the OracleCommandBuilder objects to generate your SQL statements for the OracleDataAdapter, you can also use the AddRowID method to have it automatically add ROWID to your Select statements. See “OracleCommand Class” for details on the AddRowID method.
