Companies everywhere face the same challenge: using data analytics for better decision-making. Enter Datameer — a powerful tool that gives hardworking data teams the upper hand in utilizing SQL (Structured Query Language). In this article, we’ll explore how following best practices can help optimize your workflow and improve performance with Datameer’s intuitive and game-changing features!
Best SQL Practices
Ensure your SQL coding is as efficient and accurate as possible by following a few best practices! From understanding the basics of database normalization to taking advantage of indexes for speedier queries, you can make many small tweaks that will have big performance gains. And if properly implemented, these key ideas could help lead your data architecture toward success!
- Use Proper Naming Conventions – When creating tables, columns, and other objects, use names that clearly describe what they represent. This will prevent confusion and enhance clarity in your output.
- Avoid Using SELECT * – To avoid performance issues and unnecessary data retrieval, it is recommended only to select the necessary columns when writing SQL queries instead of using SELECT *.
- Use Appropriate Data Types – To ensure accurate data, save storage space, and avoid conversion errors, use the appropriate data types for each column.
- Avoid Using Subqueries – To enhance query performance, replace subqueries with joins or temporary tables, particularly when dealing with large datasets.
- Use Indexes – Using indexes on columns frequently mentioned in WHERE clauses can minimize the number of rows scanning and enhance query performance.
- Use Prepared Statements – Using prepared statements has two benefits: improving performance by caching the query execution plan and reducing network traffic, and protecting against SQL injection attacks.
- Comment Your Code – Add comments to your SQL code to make it more comprehensible and maintainable.
Here we see an example query that follows SQL best practices:
SELECT product_name, SUM(order_total) as total_sales FROM orders JOIN product ON orders.customer_id = customers.customer_id WHERE orders.order_date BETWEEN '2022-01-01' AND '2022-12-31' GROUP BY product_name ORDER BY total_sales DESC;
