[0022] At present, when using SQL to paginate a program, the scheduling system realizes the sequential extraction and scheduling of all SQL programs, and performs a large number of repeated query and statistical operations. These SQL programs seem to be designed to solve various business problems, but they are essentially direct operations on raw data. Paging queries need to be counted ev...

Abstract

The invention provides a data query statistics method and device. The method comprises the steps of obtaining an original SQL statement, wherein the original SQL statement comprises a query condition;calling a grammar parser to disassemble the original SQL statement to obtain a disassembly result, wherein the disassembling result is used for describing hierarchical information and functional information of each function in the original SQL statement; determining a target SQL statement according to the hierarchy information and the function information, wherein a function in the target SQL statement is associated with a query condition; and generating a statistical result according to the target SQL statement. According to the method and the device, the database query and data statistics efficiency can be improved, and the method and the device can be universally used in different SQL.

Description

technical field [0001] The invention relates to the field of computer technology, and in particular, to a data query and statistics method and device. Background technique [0002] Nowadays, in a large number of program applications, each program or system is equipped with a large amount of data. If the data needs to be displayed on the page, it is necessary to query and count the large amount of data. In this case, the operation of paging query is essential. In practical applications, computer programs often run a large number of Structured Query Language (SQL) to perform paging query on the program. Among them, SQL is a database query and programming language used to access data and query, update and manage relational database systems. Paging query refers to displaying too many query or statistical results in multiple pages on a limited interface. [0003] The existing paging query can be operated in the database. MySQL's paging query is the simplest, and the query can b...
