Embodiment 1

[0080] As an exemplary embodiment, the information query engine can be called first to execute the query statement (such as SQL statement) to obtain and display the query result; then, according to the received user confirmation instruction on the query result, the data acquisition engine is called to execute the above-mentioned Query statement to obtain and output the queried data files.

[0081] In this embodiment, step 51 and step 52 are executed in sequence. Among them, by first executing step 51, the query result of a small amount of data can be obtained, so that the user can view the corresponding preview data in a very short time, and accordingly determine whether the corresponding data file is what he needs or is interested in object, so as to determine whether to download and export these data files. Then, when the user determines that the corresponding data files need to be downloaded and exported, a corresponding user confirmation instruction can be issued, so that...

Embodiment 2

[0085] As another exemplary embodiment, after the data query condition is translated into a query statement in a preset format (such as the above-mentioned SQL statement), the query statement is executed by the information query engine to obtain the corresponding query result; then, according to The received user selection instruction for the query result is combined with the selected query result object and the above-mentioned data query conditions to obtain an updated query statement, and then the data acquisition engine executes the updated query statement to obtain the queried data file.

[0086] In this embodiment, because the data retrieved by the information query engine is not all the data required by the user, for example, the user may only be interested in the query result objects of the first three pages, but in fact the query results retrieved by the information query engine include 100 Page data, if the data acquisition engine directly executes the same SQL statem...

Abstract

The application provides data query methods and devices. One of the methods can includes: acquiring a data query dimension input by a user for a data storage set; according to distribution items which are of data in the data storage set and under the data query dimension, displaying data distribution status of each distribution item; generating a data query condition for the data storage set according to a selected distribution item to execute a data query operation. Through the technical solution of the application, the data distribution status can be displayed before querying, and reasonably setting the data query condition by the user according to the same is facilitated.

Description

technical field [0001] The present application relates to the technical field of data query, in particular to a data query method and device. Background technique [0002] Users often need to obtain the data they care about from massive data for business processing or analysis. In related technologies, various forms of ad hoc query tools are provided, and query conditions can be flexibly configured according to user requirements, and real-time query in massive data can be realized accordingly. However, if the user does not understand the general situation of the massive data that needs to be queried, it is likely that the appropriate query conditions cannot be configured, resulting in multiple attempts to obtain the required data, which wastes the user's time and energy, and consumes A large number of query resources. Contents of the invention [0003] In view of this, the present application provides a data query method and device, which can display the data distributio...
