5 Most Effective SQL Query Performance Tuning Tips

Ensuring your database performs up to speed can get a bit cumbersome at times. This is because we are generally focused on the business logic, which can result in the database slowing down. A slower database not only increases the wastage of resources but can also cause severe consequences like waiting for minutes or even hours instead of seconds for pages to load.

Therefore, it is important to have tools that are effective in SQL Query Performance Tuning so that the company does not end up losing money due to poor database performance. In this article, we will provide the five best tips to achieve tuning.

1. The first tip is to enable the application to evolve independently of the other systems that require the same information from the database. On the other hand, coupling the app with the DB greatly increases the odds of facing incidental or sequential breakages.

There are multiple advantages of beginning with the use cases of any application instead of concentrating on the data that is getting stored. For starters, if there is a lesser number of fields selected from the DB at a time, then less bandwidth is used which, in turn, speeds up the query.

However, this entails a good amount of cooperation between the business shareholders and the development team in order to succeed. Even so, the reward may not be as expected. This can happen when we do not have the required understanding of how the use of our business and how the clients are reacting. In the end, all tuning needs to be done according to the customers’ behavioral patterns

2. The second tip is to use a tool that helps you identify where the problems are and fix them whether the user has a deep knowledge of the database or not. This is a great tip because we cannot fix our problems if we do not even know what or where they are!

To counter this situation, we need an SQL Query Performance Tuning tool that can bring all the potential DB problems that can occur to light. The best way to look for any issues is to search for obstacles in both the response time delay and traffic rates.

3. The third tip is often suggested with regard to SQL productivity tuning - indexing on the basis of query fields. Using indices involves maintaining a list of all the relevant fields that can be looked over much faster than searching the whole table.

The only problem is that we have to update the index whenever we modify the table, which slows the write time on the table. To counter this, we can select only those fields that are requested frequently over the application. Once you have a proper tool in motion, such fields can quickly be determined, which mostly include natural keys and foreign keys.

4. Decreasing the number of deadlocks is a big step in optimizing queries and improving your functionality. Although they are more difficult to find out and cannot always be completely removed, you can rerun the transaction or make adjustments to the structure of the table that is being searched.

5. Avoiding the use of unbound result sets is an important step in this direction as well. This is because unbounded result sets have great potential for causing problems for the user in the future. This is why you need to have software that is created with the long-term tradeoffs in mind. The most significant aspect of resolving unbounded result sets traces back to adjusting queries for company use.

By checking the traffic according to each endpoint using your monitoring tool, you can quickly single out all the problems being caused by deadlock occurrences.
