DBMS_PIPE.RECEIVE_MESSAGE and CHR(99)||CHR(99)||CHR(99) are two different methods used in DBMS (Database Management System) to communicate messages between different processes. Both of these methods have their own advantages and disadvantages, and in this article, we will compare them to help you understand when to use which one.
DBMS_PIPE.RECEIVE_MESSAGE is a built-in package in Oracle database that is used for inter-process communication. It allows communication between two processes running in the same or different databases. This method uses pipes to send and receive messages, making it a reliable option for transmitting large amounts of data. One of the major advantages of using DBMS_PIPE.RECEIVE_MESSAGE is that it supports different data types and allows you to pass multiple parameters in a single call.
On the other hand, CHR(99)||CHR(99)||CHR(99) is a built-in function in the SQL language that is commonly used for character manipulation. It is primarily used for concatenating three characters into a single string, which can then be sent as a message. Unlike DBMS_PIPE.RECEIVE_MESSAGE, this method only supports character data type and cannot handle large amounts of data. However, CHR(99)||CHR(99)||CHR(99) is much faster in terms of performance and is a lightweight option for sending simple messages.
When it comes to choosing between these two methods, it ultimately depends on your specific needs. If you need to transmit large amounts of data, then DBMS_PIPE.RECEIVE_MESSAGE would be a better option as it provides reliability and support for multiple data types. However, if you need to send simple messages and performance is a major concern, then CHR(99)||CHR(99)||CHR(99) would be a suitable choice.
In conclusion, both DBMS_PIPE.RECEIVE_MESSAGE and CHR(99)||CHR(99)||CHR(99) have their own advantages and can be used for inter-process communication. It is important to understand your requirements and choose the method that best suits your needs to ensure efficient communication between processes in your database.
