ABSTRACT:
A database server helps to streamline the retrieval of LOB values by deciding to send a locator in replacement of the LOB value, or the LOB value itself, depending upon the specific LOB value being retrieved. A threshold value is determined in a fetch query, and the LOB sizes below that threshold are sent as values in a corresponding fetch response, and the lengths above are sent as locators in the fetch response. Indicators are inserted in a fetch parameter of the response to inform the receiving client the form of retrieval that was used for each requested LOB value being returned.
