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 processing method, device, electronic equipment and medium of a DDL statement. The method comprises: acquiring an operation instruction and a dictionary object in a DDL statement to be processed; generating a corresponding DML statement according to the operation instruction and the dictionary object; encapsulating the DML statement, get and execute the corresponding script statement. The embodiment of the present invention solves the problem in the prior art that codes need to be written independently for each database object, resulting in code redundancy, reduces code redundancy, and can quickly locate and analyze codes.

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...
