Problems solved by technology

However, the SQL statements are all pre-set simple logic. When the business volume of the database surges, the SQL statement cannot cope with the expansion of the number of data tables in the database and the data volume of the data table. The execution efficiency of the server based on the SQL statement is reduced, and the server also prone to crashes etc.

Embodiment Construction

[0045] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0046] The database query method provided by this application can be applied to such as figure 1 shown in the application environment. Wherein, the terminal 102 communicates with the server 104 through the network. The server 104 receives the database query request sent by the terminal 102, and the database query request carries a service identifier; the server 104 obtains the service query type and the condition field corresponding to the service identifier; the server 104 determines the service query type, and based on the condition field and the service query The busi...

Abstract

The invention relates to a database query method and device, computer equipment and a storage medium. The method comprises the steps: receiving a database query request sent by a terminal, wherein thedatabase query request carries a service identifier; obtaining a service query type and a condition field corresponding to the service identifier; determining the service query type, and generating an SQL segment for data fragmentation and query based on the condition field and a service conversion logic corresponding to the service query type, the service conversion logic carrying statement parameters corresponding to query conditions of a service identifier; according to the SQL sentences in the SQL language segments, carrying out database division on a database, carrying out data query onthe database subjected to database division to obtain query data, and sending the query data to the terminal. By adopting the method, the SQL statement can be generated in real time according to the service identifier, so the database data processing efficiency is improved.

Description

technical field [0001] The present application relates to the database field, in particular to a database query method, device, computer equipment and storage medium. Background technique [0002] In large-scale applications, the database has become an indispensable part, and all operations on the database need to be completed through the database connection. The server needs to perform a retrieval operation on the database through a structured query language (SQL: Structured Query Language) statement corresponding to the service identifier. However, the SQL statements are all pre-set simple logic. When the business volume of the database surges, the SQL statement cannot cope with the expansion of the number of data tables in the database and the data volume of the data table. The execution efficiency of the server based on the SQL statement is reduced, and the server also prone to crashes etc. Contents of the invention [0003] Based on this, it is necessary to address ...
