Abstract

The embodiment of the invention discloses a database inquiry method and device and a database system. The database inquiry method comprises the steps of receiving an inquiry statement from a client terminal; analyzing the inquiry statement so as to obtain a function identification contained in the inquiry statement; searching N standard functions and M registered self-defining functions for a first function corresponding to the function identification, wherein the M and the N are natural numbers; if the first function corresponding to the function identification is found, obtaining first function calling interface information corresponding to the first function, calling the first function to search a database according to the obtained first function calling interface information, and feeding the processing result obtained through the operation carried out by the first function for searching the database back to the client terminal. According to the technical scheme, the database inquiry function is expanded, and the usability of database inquiry is improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a database query method and device and a database system. Background technique [0002] With the development of computer technology, more and more systems and applications appear. The scale of systems and machines is also getting larger and larger, and system tuning is a must for larger systems. The basis of system tuning is to analyze performance data, and the method of collecting performance data is mostly sampling. [0003] Due to problems such as short sampling intervals (generally at the second level), large-scale machines, and long-running applications in the system, there may be a large number of sampling points for performance data, resulting in a large amount of data that needs to be processed and analyzed. Data can also be more complex. In the processing and access of large-scale data, the database has better performance. But in terms of database query, the existi...
