SQL
Also written: Structured Query Language
SQL is a language for managing and querying databases. It lets users ask questions of data and change it.
SQL, which stands for Structured Query Language, is a special computer language used to talk to databases. Think of a database like a huge, organized filing cabinet. SQL is the set of instructions you use to find specific files, add new ones, or change the information in existing files.
For example, if a company has a database of all its customers, you could use SQL to ask for a list of all customers who live in California and have spent more than $100. The database would then return that specific list to you. It's a fundamental tool for anyone working with data.
SQL (Structured Query Language) is a domain-specific language used in programming and designed for managing data held in a relational database management system (RDBMS). It is used to perform tasks such as data retrieval, data manipulation (insert, update, delete), and data definition (create, alter, drop tables and other objects). SQL commands are declarative, meaning users specify what they want the database to do, not how to do it. The RDBMS handles the execution plan.
Its widespread adoption and standardization (ANSI SQL) make it a ubiquitous tool in data science, backend development, and business intelligence. While powerful, its declarative nature can sometimes lead to performance tuning challenges, and it is not designed for complex analytical operations that might require more specialized languages like Python with libraries such as Pandas.
SQL is relevant as frontier AI labs build agents that need to interact with structured data. These agents must understand how to query databases to retrieve information or perform actions, and SQL is the standard language for this. The ability to translate natural language into SQL queries is a key capability for data-focused AI agents.

- OpenAI's internal data agent uses natural language to query vast datasets, implying a need to interact with structured data, likely via SQL.
SQL was developed at IBM in the early 1970s by Donald D. Chamberlin and Raymond F. Boyce. It was based on the relational model proposed by Edgar F. Codd. Source ↗
You can try SQL using online interactive tutorials or by installing a local database like SQLite. Many websites offer "try SQL" features where you can write and run queries against sample databases to see how it works.

Questions people ask
- What does SQL stand for?
- SQL stands for Structured Query Language.
- Is SQL hard to learn?
- Basic SQL commands are relatively easy to learn, especially for simple queries. More advanced features and optimization can be complex.
- Can AI write SQL?
- Yes, modern AI models can generate SQL queries from natural language descriptions, a process called text-to-SQL.
