Abstract

The invention discloses a data acquisition method and device. The method comprises the following steps that: after a client side accesses a preset name database in a server, sending a data acquisitionrequest to the server, and receiving feedback data sent from the server, wherein the feedback data is data which is search from the preset name data by the server and corresponds to the data acquisition request; and according to a preset screening rule, screening the feedback data, obtaining screened data to enable the server to search feedback data corresponding to the data acquisition request from the preset name database to realize the automatic acquisition of the data. Therefore, a user does not need to manually screen the feedback data through the client side, and the workload of the user is lowered.

Description

technical field [0001] The present invention relates to the technical field of database processing, and more specifically, relates to a data acquisition method and device. Background technique [0002] Impala is a distributed database located on the server side. In the distributed database of Impala, there are two types of entities, table and view. The two entities, table and view, can use Impala to execute table creation statements and view statement statements to build tables and views. , and after the table and view are built, the table creation statement and the view statement statement will be stored in a database of Impala, such as the table creation statement and the view statement statement will be stored in the database named dbName in the Impala database. [0003] When the user views the table creation statement and view creation statement in the database named dbName under Impala through the client, the user needs to copy the table creation statement and view crea...
