Receipt sub-table row-correlated query device and method

The invention provides a receipt sub-table row-correlated query device. The receipt sub-table row-correlated query device comprises a business interface providing unit for providing corresponding universal receipt interfaces based on the incidence relation of business receipts to be queried, and a business correlated query unit for invoking the corresponding receipt interfaces to perform recursive call query incidence relation and store and display business data obtained according to the recursive call query incidence relation. The invention further provides a receipt sub-table row-correlated query method. By means of the technical scheme and based on an existing correlated query mode, single-object types can be fully utilized to complete correlated query of multi-object types and establish a multi-object type involved universal and unified correlated-query thought.
