Abstract

The embodiment of the invention provides a function dynamic creation method and device and electronic equipment. The method comprises the following steps of when obtained SQL statements of the storageprocess comprise a function creation statement and a storage process creation statement, storing the function creation statement; analyzing the function creation statement and the storage process creation statement respectively to generate a first java file and a second java file which correspond to each other, compiling the first java file and the second java file respectively to obtain a firstexecutable file and a second executable file, and finally loading the first executable file and the second executable file into a memory. Thus, a self-defined function can be dynamically created in the creation and storage process, calling of the self-defined function in the subsequent storage process is facilitated, and cross-platform use can be supported based on the universality of a java code,a java class self-defined function and a storage process.

Description

technical field [0001] The present application relates to the technical field of databases, in particular, to a method, device and electronic equipment for dynamically creating functions. Background technique [0002] In traditional relational databases, database custom functions and stored procedures play an important role, are widely used, and are indispensable capabilities of database software. Each function of a stored procedure created in a traditional database can only be performed independently. If the stored procedure needs to call a custom function, the function needs to be created and compiled before it can be used. It is impossible to dynamically create custom functions during the execution of stored procedures, which limits flexibility to a certain extent. Contents of the invention [0003] In view of this, the object of the present application is to provide a method, device and electronic device for dynamically creating a function to improve the above problem...
