Abstract

The invention provides a data dynamic querying method and a device. The data dynamic querying method includes the steps of providing a user interface to generate a dynamic tree querying structure, receiving at least user input on the user interface to generate the dynamic tree querying structure, performing the data querying according to at least one input item of the leaf node of the dynamic treequerying structure, and performing relation operation on the queried data layer by layer according to the relation operation information of a sub-nested querying group and transmitting to a root nested querying group to obtain querying results. The data dynamic querying method and the device can reduce the maintenance cost of querying components.

Description

technical field [0001] The invention relates to the field of data query, in particular to a method and device for dynamic data query. Background technique [0002] At present, many webpages or application programs often need to be used in combination with database or page data, and often face the problem of accessing database or page data. At present, the data query function generally involves static query conditions, that is, the query conditions are pre-set on the query page, and the user fills in the corresponding query data in the query conditions that require data query according to each query condition. After filling in the corresponding query data in the query condition of the data query, the corresponding query is performed in the database or page data, and the query result is fed back to the user. [0003] However, in this way, the data structure of the database or page data and the query conditions are preset and tightly coupled. The addition and deletion of query...
