Abstract

The invention relates to a process language SQL statement processing method and device, a medium and electronic equipment. The process language SQL statement processing method comprises the steps of:analyzing a first process language SQL statement, and acquiring a statement header and a statement body of the first process language SQL statement; encrypting the statement body of the first processlanguage SQL statement; and determining an encrypted first process language SQL statement based on the encrypted statement body, the statement header and an encryption keyword, wherein the encryptionkeyword is used for instructing that grammatical analysis is not performed on the statement body of the encrypted first process language SQL statement before the encrypted first process language SQL statement is compiled and executed. According to the process language SQL statement processing method and the device of the invention, the encrypted PL / SQL statement is used in a database, the use of normal functions of the database is not influenced basically, the influence on a database system is reduced, the system performance is improved, and meanwhile, the security of PL / SQL object codes is improved.

Description

technical field [0001] The embodiments of the present disclosure relate to the technical field of databases, and in particular to a procedural language (PL) SQL statement processing method, a procedural language SQL statement processing device, and a computer-readable storage medium for realizing the procedural language SQL statement processing method and electronic equipment. Background technique [0002] As an integral part of the computer system, the database plays a vital role in data storage and processing. With the increasing frequency of use and the increasing number of usage scenarios, the database has an increasing demand for data code security. Big. [0003] The current database system not only supports structured query language SQL (Structured Query Language), usually also supports procedural language PL / SQL, PL / SQL is an extension of SQL statement, adding the characteristics of programming language to the use of ordinary SQL statement , based on PL / SQL statemen...
