In SQL, the following main commands are used for inserting and retrieving data:
-
INSERT INTO — command for adding new records to a table.
Example:
INSERT INTO users (name, age) VALUES ('Ivan', 30); -
SELECT — command for retrieving data from a table.
Example:
SELECT name, age FROM users WHERE age > 25;
These commands allow adding new data and extracting the necessary information from the database.
