9 ways to tune SQL performance
Tags: sql, performance
Published: 2023-02-06 06:42:44

Here are explanations and examples for the 9 techniques to improve the performance of SQL:

##1. Indexing: 
Create an index on columns that are frequently used in search and join conditions to speed up query execution. For example, suppose you have a table named "orders" and you frequently search for orders by customer ID:

```SQL
CREATE INDEX idx_orders_customer_id ON orders (customer_id);
```

##2.Normalization: 
Normalize the database tables to minimize data redundancy and improve data integrity. For example, consider a table named "orders" that contains both customer and order information. Normalize this table into two separate tables, "customers" and "orders", to reduce data redundancy.
[Learn more](https://dev.to/yogini16/database-normalization-41gg) 

##3. Query optimization: 
Use the EXPLAIN statement to analyze query execution plans and optimize SQL queries for performance. For example:

```SQL
EXPLAIN SELECT * FROM orders WHERE customer_id = 123;
```

##4. Use proper data types: 
Use appropriate data types for columns to reduce memory usage and improve query performance. For example, use an integer data type for the "customer_id" column instead of a string data type.

##5. Partitioning: 
Partition large tables into smaller, more manageable pieces to speed up queries and improve manageability. For example, partition the "orders" table by order date

```SQL
CREATE TABLE orders_2022 PARTITION OF orders FOR VALUES FROM ('2022-01-01') TO ('2022-12-31');
```

##6. Avoid N+1 queries: 
Use JOINs or subqueries instead of multiple single row queries to reduce the number of database round trips. For example, use a join to retrieve all orders and customer information in a single query:

```SQL
SELECT o.*, c.*
FROM orders o
JOIN customers c ON o.customer_id = c.id;
```

##7. Caching: 
Implement caching at the application level or use database caching mechanisms like query result caching to reduce the load on the database.

##8. Avoid wildcard searches: 
Use specific searches with indexes instead of wildcard searches, which can be slow and resource-intensive. For example, search for a specific customer name instead of using a wildcard search:

```SQL
SELECT * FROM customers WHERE name = 'John Doe';
```

##9. Use prepared statements: 
Use prepared statements instead of dynamically constructing and executing SQL statements to reduce parse time and improve performance. For example:

```SQL 
PREPARE stmt1 FROM "SELECT * FROM orders WHERE customer_id = ?";
EXECUTE stmt1 USING 123;
DEALLOCATE PREPARE stmt1;
```

[Petpooja](https://www.petpooja.com/) was first established in 2011 as a food delivery platform for corporate clients, similar to popular platforms like Zomato and Swiggy. Within just two years, the company had made a significant impact, serving over 200 corporations and partnering with 300+ restaurants.
However, despite their initial success, the team at Petpooja noticed that the lack of proper technology was causing major operational inefficiencies and hindering the scalability of restaurant processes. After taking a closer look at the challenges faced by these restaurants on a daily basis, Petpooja underwent a transformation and evolved into a comprehensive Restaurant Management software solution.

---

Numerous prospective programmers and developers have faced the phenomenon known as "tutorial hell." It occurs when someone spends many hours completing tutorials without making any headway toward finishing a real project. This may demotivate people and cause them to feel frustrated and stuck.

Because it doesn't provide students the chance to apply what they've learned to a real-world assignment, tutorial hell is wrong. Tutorials sometimes concentrate on teaching certain methods or technology; however, they don't always offer a thorough grasp of how to create and manage a real-world project.

It's crucial to mix learning through tutorials with practical experience if you want to avoid tutorial hell and achieve real progress. This involves using what has been taught on practical tasks and enhancing one's skill set over time.

The following advice can help you avoid tutorial hell:

**Set precise objectives and benchmarks.** Have a clear idea of what you want to accomplish, and then define goals and benchmarks to evaluate your progress.

**Build practical projects**. To obtain practical experience, apply the knowledge you have gained from tutorials to practical projects.

**Work on projects with other developers** or contribute to open-source initiatives to increase your abilities and expertise.

To gain from their knowledge and advance your abilities, **get feedback on projects** from seasoned developers.

Keep up with changing technology and methods by **continuing to learn new things** and broadening your skill set.

To sum up, tutorial hell is a prevalent issue experienced by aspiring programmers and developers. It's crucial to strike a balance between learning through tutorials and practical experience while also consistently improving your abilities in order to prevent this issue and achieve significant progress. Developers may escape tutorial hell and make significant strides in becoming productive programmers by paying attention to these pointers.
