Abstract

The invention discloses a database index processing method and device. The database index processing method comprises the steps of obtaining the annotation information of pre-added indexes, wherein the annotation information is used for recording the original format used by the indexes; carrying out analysis on the annotation information to obtain the original format used by the indexes and recorded by the annotation information, obtaining metadata of the indexes; carrying out comparison on the original format used by the indexes recorded by the annotation information and the metadata of the indexes; obtaining the using information of the indexes according to comparison results. Through the database index processing method and device, the effect of carrying out detection on the using situation of the indexes is achieved, and maintenance on the indexes is convenient to carry out.

Description

technical field [0001] The present invention relates to the field of databases, in particular to a database index processing method and device. Background technique [0002] In the use of the database, the index is used very frequently, which has a great impact on the performance of the database, so some indexes need to be maintained for a long time. In the existing technology, these indexes rely on artificial memory to remember the use of the index, but after a long period of time, they will forget for which situations the originally established index was used, and in which Structured Query Language (Structured Query Language) , referred to as SQL) are used. Since the use of the indexes cannot be detected, the use of these indexes cannot be known, and the impact of the use of the indexes cannot be evaluated. [0003] Aiming at the problem that the use of indexes cannot be detected in the prior art, no effective solution has been proposed yet. Contents of the invention ...
