Abstract

The embodiment of the invention provides a data processing method and device, equipment and a storage medium, and the method comprises the steps: firstly, obtaining a target model corresponding to an expression in a data query request, wherein the expression comprises a constraint condition; secondly, inputting the expression and target data in a column database into a target model to obtain an execution result corresponding to the constraint condition; wherein the target data comprises all data in at least one column and partial data in at least one column; and then, outputting an execution result. The method and the device are used for solving the problem that the data query speed of SQL statements is low due to too low data processing efficiency in related technologies.

Description

Technical field [0001] The present invention relates to the field of communication technologies, and more particularly to a data processing method, apparatus, device, and storage medium. Background technique [0002] When the user uses the structured query language (STRUCTURED Query Language, SQL), data query can be performed by an iterator model. In the iterator model, the expression is input by an abstract iterator, and the data of each data table in the database is performed by the iterator, thereby calculating the results of each row, and output multi-line result output as an output. Take the corresponding data. [0003] However, this abstract iterator will bring performance loss, because in the process of iterators, each line of data will lead to multi-layer function calls, at the same time, acquire data progressively Multi-write and output, consume more resources, resulting in excessive calculation, reducing data processing efficiency, and reduces data query speed of SQL st...
