Your First Query
SQL (Structured Query Language) is the standard language for working with data in databases. The most fundamental SQL statement is `SELECT`, which retrieves data from a table.
The simplest query looks like this:
SELECT * FROM table_name
The asterisk (`*`) means "all columns". This query returns every row and every column from the specified table.
