Can you explain how SQL works?
Sure! SQL, or Structured Query Language, is used to communicate with databases. It allows you to create, read, update, and delete data.
What are the main components of SQL?
The main components include commands like SELECT, INSERT, UPDATE, DELETE, and clauses like WHERE, JOIN, and ORDER BY.
How do I write a basic SQL query?
A basic SQL query looks like this: SELECT column_name FROM table_name WHERE condition;
This retrieves specific data from a table.
Can you give me an example of a JOIN operation?
Certainly! A JOIN operation combines rows from two or more tables based on a related column. For example: SELECT * FROM table1 JOIN table2 ON table1.id = table2.foreign_id;
