Abstract

The invention discloses a sub-table data processing method and device, and relates to the technical field of computers. A specific embodiment of the method comprises the steps of obtaining to-be-processed data and an instruction of a dynamic structured query language; judging whether the to-be-processed data carries a primary key or not; if so, determining a data table corresponding to the to-be-processed data according to a data table number in the primary key; and in the data table, processing the to-be-processed data according to the instruction of the dynamic structured query language. According to the embodiment, the technical means of directly and correctly positioning the data table according to the primary key is adopted. All data tables needing to be operated do not need to be circulated, the problem of circulation redundancy caused by the complexity of database composition is effectively avoided, the efficiency of processing the sub-table data is improved, then the pressure of processing the data in the database is reduced, and the performance of the database is improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for processing sub-table data. Background technique [0002] Table splitting can refer to storing data originally stored in one table in blocks into multiple data tables, and table splitting data can refer to data stored in each data table after table splitting. For the processing of sub-table data, in the prior art, since the data table storing the data to be processed cannot be directly located, the data records corresponding to all tables can only be queried globally, that is, processing operations such as query, modification, and deletion all need to be cycled. For all the data tables, the processing results in each data table are obtained, and then all the processing results are aggregated. [0003] In the process of implementing the present invention, the inventors have found at least the following problems in the prior art: the performance and effici...
