Abstract

The embodiment of the invention discloses a big data query method and device, and the method comprises the steps: carrying out classification on a plurality of query components according to query language to obtian a querycomponent set with the same query language classification; configuring corresponding relationship between each query component in the query component set and the name of each data table and each query field; obtaining the name of the data table and the input content of the query field determined by the user, determining a corresponding query component in the query component set by utilizing the corresponding relationship, filling the query language with the name of the data table and the input content of the query field, and by utilizing the corresponding query component,querying data in the data table according to the query field and the input content of the query field. Therefore, according to the embodiment of the invention, a user does not need to select a specific query component of the database, and for the user, big data query is more convenient.

Description

technical field [0001] The present application relates to the field of computers, in particular to a big data query method and device. Background technique [0002] With the rapid development of Internet technology, the world has entered the era of big data. There are currently many databases that can store big data. When data needs to be queried, users can use query components to query data in the database. For example, you can use the query component Impala to query data in the database Hive. When performing data query, the query component uses the query language to query in the data table. The query component locates the data table where the data to be queried is located according to the name of the data table in the query language, and queries the data in the table according to the field name of the data in the query language, where the field name of the data represents an attribute of the data , for example, the field name of the data Zhang San is the customer name, t...
