Problems solved by technology

In the implementation process of each DDL statement, each database object needs to write independent code, that is, the code between different database objects cannot be shared, resulting in code redundancy, which in turn makes code maintenance and inspection a large workload and complex logic

Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0024] figure 1 It is a flow chart of a method for processing a DDL statement provided by an embodiment of the present invention. This embodiment is applicable to performing equivalent transformation on a DDL statement to be processed, and generating a corresponding Data Manipulation Language (Data ManipulationLanguage, DML) statement to reduce code In the case of redundancy, the method can be executed by a DDL sentence processing device, the DDL sentence processing device can be implemented by software and / or har...

Abstract

The invention discloses a DDL statement processing method and apparatus, an electronic device and a medium. The method comprises the steps of obtaining an operation instruction and a dictionary objectin a to-be-processed DDL statement; generating a corresponding DML statement according to the operation instruction and the dictionary object; and packaging the DML statements to obtain and execute the corresponding script statements. According to the embodiment of the invention, the problem of code redundancy caused by the fact that each database object needs to be subjected to independent codecompiling in the prior art is solved, the code redundancy is reduced, and codes can be quickly positioned and analyzed.

Description

technical field [0001] Embodiments of the present invention relate to data processing technologies, and in particular to a method, device, electronic equipment and media for processing DDL statements. Background technique [0002] In today's large-scale relational databases, the Data Definition Language (Data Definition Language, DDL) function is an essential function. How to efficiently execute DDL statements and handle concurrent DDL statements is a complex task. [0003] Currently, in a relational database, storing database objects in memory is directly manipulating the data in the system table at runtime. In the implementation process of each DDL statement, each database object needs to write independent code, that is, the code between different database objects cannot be shared, resulting in code redundancy, which in turn makes code maintenance and inspection a large workload and complex logic . Contents of the invention [0004] Embodiments of the present invention...
