Abstract

The invention provides data query method and device. The method comprises the following steps: acquiring, via a uniform query interface, one or more fields selected by a user through a client; generating a query sentence according to the selected fields; sending the query sentence to a database; and receiving a dataset returned by the database. Since the user can freely select the to-be-queried field and conduct query through the uniform query interface, the generation of many duplicated codes is avoided, and the server resources are saved; and moreover, the data of the fields not for query isnot leaked, thereby enhancing the data security.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of databases, in particular to a data query method and device. Background technique [0002] With the explosive growth of information volume, the storage capacity requirements for databases storing various information are getting higher and higher. Facing the storage of big data, the query requirements for data are getting higher and higher. [0003] The query methods for data in the prior art mainly include two types. One is to query the data of fixed fields, and the other is to query the data of all fields. [0004] For the data query method of fixed fields, if you query different combinations of fields in the same table, you need to write multiple query functions or interfaces, resulting in a lot of repeated code and a waste of server resources. The data query method of all fields, each query returns the data of all fields, the data of useless fields wastes server resources an...
