Error Handling During Query Execution In Mysql
Errors are an inevitable part of software development, and MySQL databases are no exception. Understanding how to handle errors effectively is crucial for building robust and reliable applications. Fun Fact Studies show that well-handled errors can improve application reliability by up to 70!
During test case development, it is useful to process all input even if errors occur so that you can see all errors at once, such as those that occur due to typographical or syntax errors. Otherwise, you can see and fix only one scripting problem at a time.
In this tutorial, we will learn how we can handle the errors effectively in the MySQL stored procedures. We will see multiple aspects and possibilities while
Analyze Execution Plans Use EXPLAIN before your query to get information on how MySQL will execute it. Monitor Server Health Regularly check server status variables to monitor performance and potential problems.
While working with stored procedures in MySQL if an exception or occurs the execution of the procedure terminates abruptly, to avoid this you need to handle the exceptions in MYSQL.
