A program code conversion method, device, medium and computing device

Abstract

Embodiments of the present invention provide a program code conversion method, device, medium and computing equipment. The method includes: reading the source code of the program sentence by sentence; judging whether the currently read program statement is a specific statement; if yes, converting the program statement into an intermediate code; interpreting and executing the intermediate code; if not, directly interpreting and executing the program statement. This method judges whether the current program statement is a specific statement, and interprets and executes the program statement according to the judgment result, so as to realize the automatic identification and dynamic modification of the program statement, which helps to simplify the modification plan of the program statement and reduce the implementation logic of the program statement Complexity and maintenance difficulty, improve the versatility of program statements.

Description

technical field [0001] Embodiments of the present invention relate to the field of software, and more specifically, embodiments of the present invention relate to a program code conversion method, device, medium, and computing device. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] Optimistic Lock is suitable for multi-read application types and helps to improve the throughput of database tables. In the optimistic locking solution based on the data version (Version) mechanism, the data version is a version identifier used to indicate data changes. By adding a data version (such as a version field) to the database table, the data to be submitted can be judged when the data is submitted. Whether it is expired data, if the data to be submitted is not expired data, the data...

AI Technical Summary

Problems solved by technology

However, at present, the implementation of optimistic locking solutions mostly depends on manually added judgment conditions. Since the judgment conditions in the optimistic locking solution are set in the core logic statement, the implementation logic of optimistic locking is completely coupled to the business code, resulting in the current optimistic locking solution. There are problems such as complex implementation logic, difficult maintenance, low versatility, and poor pluggability

In addition, due to the large number of database tables involved in the judging conditions in the current optimistic locking solution, it will further lead to the development and maintenance difficulties of optimistic locking.
