Embodiment 1

[0053] In order to solve the problem in the prior art that when querying the total number of qualified data in the database, it is necessary to perform a comprehensive scan of the data in the database and accumulate the total number of eligible data, resulting in low query efficiency. The embodiment of the present application provides a The data query method, the method provided by this embodiment can be applied to any device, and the device can be a PC (Personal Computer, personal computer), a mobile phone, a tablet computer, a notebook computer, a virtual host, etc.; it can also be a server, for example, a machine Rack server, blade server, tower server or rack server (including independent server, or server cluster composed of multiple servers), etc.

[0054] For the flowchart of the method provided by the embodiment of this application, please refer to figure 1 ,include:

[0055] S11: Obtain the query field condition to be queried, the query field condition includes the i...

Embodiment 2

[0117] The embodiment of this application provides a data query device, please refer to Figure 12 shown, including:

[0118] The acquiring module 1201 is configured to acquire the query field condition to be queried, the query field condition includes the information of the query field in the database and the limited data corresponding to the query field.

[0119]The model matching module 1202 is used to match the target statistical tree model from the preset statistical tree model library according to the query field condition, and each statistical tree model in the statistical tree model library includes the database and the preset query field condition In the generated node layer, each node in the node layer records the information of the query field, the corresponding limited data and statistical values ​​of the node, and the statistical value recorded in each node in the node layer is when the query field recorded by the node satisfies the The limited data recorded by t...

Embodiment 3

[0134] Based on the same inventive concept, the embodiment of this application provides a device, please refer to Figure 13 As shown, it includes a processor 1301 and a memory 1302. The memory 1302 stores a computer program, and the processor 1301 executes the computer program to implement the steps of the data query method in the first embodiment above, which will not be repeated here.

[0135] understandable, Image 6 The structure shown is for illustration only, the equipment may also include Image 6 more or fewer components than shown in, or with Image 6 Different configurations are shown.

[0136] The processor 1301 may be an integrated circuit chip with signal processing capability. The above-mentioned processor 1301 can be a general-purpose processor, including a central processing unit (Central Processing Unit, CPU), a network processor (NetworkProcessor, NP), etc.; it can also be a digital signal processor (DSP), an application-specific integrated circuit (ASIC)...

Abstract

The invention provides a data query method, device and equipment and a computer readable storage medium, a target statistical tree model can be matched according to a to-be-queried query field condition, and each node in the target statistical tree model records a statistical value of a query field under corresponding limited data, so that the statistical value of the query field under the corresponding limited data is more accurate. Therefore, the data statistical value meeting the condition requirements of the query field to be queried in the database can be directly determined according to the information recorded by the corresponding node in the target statistical tree model, the data in the database does not need to be comprehensively scanned, and the query efficiency is higher.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular, to a data query method, device, equipment, and computer-readable storage medium. Background technique [0002] There are a large amount of data stored in the database. In many business scenarios, it is usually necessary to query the data in the database according to the actual business needs. For example, when querying the total number of qualified data, the current common practice is to query the data in the database Carry out a comprehensive scan, accumulate the total number that meets the query conditions, and then return the results. As the amount of data increases, the scan time becomes longer and the performance becomes lower and lower, which cannot meet the usage requirements in actual scenarios. Contents of the invention [0003] The purpose of the embodiments of the present application is to provide a data query method, device, equipment, and computer-rea...
