Developing OTDs for Database Adapters

ProcedureTo Add Prepared Statements


Note –

When using a Prepared Statement, the ResultsAvailable() method will always return true. Although this method is available, you should not use it with a while loop. Doing so would result in an infinite loop at runtime and will stop all of the system’s CPU. If it is used, it should only be used with the if statement.
