This article is about the pros and cons of oracle stored procedures. The editor thought it was very practical, so I shared it with you as a reference. Let's follow the editor and have a look.

Oracle stored procedure has the advantages of simplifying complex operations, reducing the probability of errors, fast execution speed and good adaptability. Its disadvantages are poor portability, occupying more resources on the server side, increasing server pressure, and so on.

Oracle is a relational database management system developed by Oracle. It is favored by everyone because of its good portability, easy to use and powerful function.

Stored procedure

A stored procedure is a set of SQL statements that are compiled and stored in the database in order to complete a specific function. The user executes the stored procedure by specifying the name of the stored procedure and giving parameters. This way saves users' time and improves the execution efficiency of the program. There are some default stored procedures in the database, which can be called directly by raising the name of the stored procedure. In addition, stored procedures can be called in programming languages, such as Java,C#, etc.

Advantages of stored procedures

(1) simplify the complex operation

In the stored procedure, multiple SQL statements are encapsulated into a separate unit, and the user only needs to call it. This increases the independence of the data, and when the data structure changes, the stored procedure can be modified to achieve it, so that there is no need to modify the program code to improve security.

(2) reduce the probability of errors.

If you do not use stored procedures to implement an operation, you may need to execute multiple separate SQL statements, and too many steps are likely to cause errors. The stored procedure only needs to be compiled once and can be called directly.

(3) Fast execution

The database has parsed and optimized the stored procedure once when it was created. In addition, after the stored procedure is executed, a copy is kept in memory, so the next time it is executed, it can be called directly in memory.

(4) good adaptability.

Because the stored procedure accesses the database through the stored procedure, the database developer can make any changes to the database without changing the stored procedure interface, and these changes will not affect the application.

Disadvantages of stored procedures

(1) if the scope of change is so large that you need to change the parameters of the input stored procedure, or if you want to change the data returned by it, it is more difficult to change the parameters in the program.

(2) portability is poor, because stored procedures bind applications to SQL Server, so using stored procedures to encapsulate business logic will limit the portability of applications.

(3) it takes up more resources on the server, which causes great pressure on the server.

(4) poor readability and maintainability

Thank you for reading! So much for sharing the advantages and disadvantages of oracle stored procedures. I hope the above content can be helpful to you so that you can learn more knowledge. If you think the article is good, you can share it and let more people see it.
