Best AI Tool for SQL Query Optimization

After you write a query, especially a complex one, you need to make sure it will be efficient in terms of resource consumption. This is particularly relevant for queries that need to be executed on a regular basis. You don't want them to have a negative impact on the overall performance of your databases. And here, you can either learn all the best practices for writing cost-effective queries or let the AI do the job for you.

Yes, you got that right—AI is already smart enough to take your manually written query, analyze its cost, find potential performance issues and bottlenecks, and fix them. In the end, you get an optimized query that processes your data in the fastest possible way.

A brief overview of the AI SQL query optimizer in dbForge AI Assistant

We can suggest an SQL AI tool that can make it happen. It's called dbForge AI Assistant, and it was designed to generate context-aware queries based on your requests, explain parts of SQL code, and locate potential troubles with your queries. Additionally, it can act as a smart query optimizer that provides you with recommendations on improving the performance of your queries.

dbForge AI Assistant is integrated into multiple dbForge products for SQL Server, MySQL, MariaDB, Oracle, and PostgreSQL databases. It is aware of the specifics of each database system and consults you accordingly. You only have to ask, and the Assistant will give you an exhaustive answer, plain and simple, all in a matter of moments.

The key features of dbForge AI Assistant for SQL optimization

SQL optimization is one of the main tasks that can be simplified via dbForge AI Assistant. Here's what you can do with its help.

Automated query optimization

dbForge AI Assistant uses natural language processing to understand your requests. All you need to do is give the Assistant a query and ask to optimize it. You will instantly get a result with structural improvements, optimal indexing strategies, and detailed explanations. You can just as well retrieve information about anti-patterns such as unnecessary JOINs, expensive subqueries or wildcard selections; naturally, these anti-patterns will be accompanied by optimized alternatives.

Query performance insights

Want to find potential performance issues in your queries? Again, you can ask the Assistant. It will analyze query execution plans, highlight slow operations like full table scans, and recommend improvements that will decrease redundancy and make your queries faster and cheaper. No bottleneck will remain uncovered.

Cost-effective query improvements

How about advice on minimizing resource usage? You got it. dbForge AI Assistant can suggest query restructuring that achieves the same results with much lower resource consumption. It can predict costs of query variations, helping you choose the most efficient one. You can optimize data scans in order to avoid excessive data processing. Finally, the Assistant can consult you on partitioning or materialized views for recurring queries—all based on your particular case, of course.

Real-time SQL query analysis

If you are actively using AI tools, you know well that they do the job promptly and effectively. After all, one of the key goals of AI is to save your precious time. dbForge AI Assistant is no different in this respect; it performs query analysis and optimization in the wink of an eye, gives you immediate feedback, and thus helps shift your focus to reviewing that feedback and picking the optimal path.

How does the AI query optimizer work?

Now that we're through with the key features, let's see the workflow of query optimization via dbForge AI Assistant.

Compatibility with popular database systems

dbForge AI Assistant is integrated into multiple dbForge tools, most notably our multidatabase solution dbForge Edge, which comprises four dbForge Studios, high-end IDEs that help you simplify interactions with your databases and perform a variety of operations with data. You can also use the Assistant with any of the individual Studios:

• dbForge Studio for SQL Server
• dbForge Studio for MySQL
• dbForge Studio for Oracle
• dbForge Studio for PostgreSQL

Note that the Studios may cover a variety of related databases and cloud services. For instance, the Studio for SQL Server works just as well with Azure SQL, the Studio for MySQL is perfectly compatible with MariaDB, and the Studio for PostgreSQL can be used to access Amazon Redshift.

Finally, there is a number of other specialized dbForge products that can be used along with the Assistant. All of them—bar the completely free products, of course—are available for a free trial, so you can give them a proper go at any moment. All you need to do is download and install the required dbForge product. The Assistant will be available in it.

Machine learning algorithms in action

dbForge AI Assistant is based on a single LLM, OpenAI, and does not have access to the actual data of your databases. However, it reads the metadata to be aware of the context. Thus it can make smart, relevant suggestions related to your particular database schemas, letting you use it as an intelligent AI schema generator. In this section, we'll see the Assistant in action.

Once you have both the required dbForge product downloaded and installed on your machine, you can proceed to open the said product and connect to the required database server. Next, you open the Assistant and input your request in natural language. Here's how it works.

Easy, wasn't it?

SQL query rewriting and refactoring

dbForge AI Assistant can analyze the structure, semantics, and performance characteristics of SQL code and make it more efficient, readable, and maintainable in the following ways.

• Identify inefficient patterns and replace them with best-practice equivalents (e.g., replace an unnecessary subquery with a more cost-effective JOIN)
• Understand the goal of your query (what data is being retrieved and how) and restructure it for better clarity (e.g., break complex queries into modular parts)
• Detect whether your query is not using existing indexes effectively and suggest improvements (e.g., rewrite WHERE clauses or JOIN conditions so as to replace functions on columns with equivalent indexed expressions)
• Find redundant JOINs or filters and remove them
• Rename aliases or table names for better clarity and consistency
• Break down complex queries into reusable views or stored procedures

These are just several examples of how the Assistant can optimize your queries. It is capable of much more—you only have to ask.

The benefits of using dbForge AI Assistant for SQL optimization

At the end of the day, what do you get with dbForge AI Assistant at hand?

Improved query speed and efficiency

A combination of faster query execution and low resource consumption is definitely the key benefit of query optimization. There's hardly much to be added here.

Reduced development time

Another obvious benefit is that you no longer have to remember all the best practices for making queries more efficient and optimize them manually. The Assistant relieves you of all that. Like we mentioned, now you only have to double-check the automatically optimized query and make minor adjustments, if necessary. Thus, you will spend much less time on your routine SQL development.

Enhanced scalability

Finally, if your data volumes are steadily growing, your query workloads increase, and the number of users goes up as well, manual optimization might not be sufficient. As opposed to that, the workload-aware Assistant will easily take care of optimizing resource-intensive queries for consistent performance across all of your databases.

The future of SQL query optimization with AI

We are moving towards more autonomous query optimization, where AI can predict performance issues and rewrite inefficient queries in real time without much developer input, optimize execution plans, and provide insightful consultations on nearly any subject matter. Sure, your watchful eye has to review the output, regardless of the AI you are currently using. But still, it's an effective time saver at your disposal—and dbForge AI Assistant is awaiting your first request to prove it's so.

We've always said that nothing can replace firsthand experience. Thus we gladly invite you to download and install the dbForge product of your choice, enable the integrated AI Assistant, and explore their capabilities via real-life tasks. Your experience with SQL coding and optimization won't be the same.
