| description | Methods, systems, apparatuses, and computer program products are provided for processing queries. A data server includes a query processor configured to receive a query from a database application, which was received by the database application from a requestor. The query is directed to data stored at the data server. The query processor includes a deferred evaluation determiner and deferred expression determiner. The deferred evaluation determiner is configured to analyze the query, and to designate the query for deferred evaluation by the database application if a predetermined factor is met, such as the query including an operation on encrypted data that is not supported at the data server. The deferred expression determiner is configured to determine expression evaluation information for evaluating at least a portion of the query at the database application. The query processor provides the encrypted data and the expression evaluation information to the database application for evaluation. |
