ABSTRACT:
A method and apparatus for efficiently transmitting a result set. A data server receives a data request from a client or another server. The data server determines whether a threshold portion of the contents of each requested row or record is being retrieved (e.g., X% of the number of columns in a table or X% of the total amount of data in a table row). The requested rows are retrieved in the same format in which they are stored (e.g., within a disk block), and streamed to the client, one row at a time. The client is then responsible for disassembling a row into its columns, reordering them if necessary, and performing any necessary post-processing (e.g., datatype conversion, data formatting) before consuming the data.
