What methods can be used to set a limit on the number of selected records from a database?

To set a limit on the number of selected records from a database, the following methods are usually used:

1. SQL query with the LIMIT keyword (or its equivalent, depending on the DBMS):

SELECT * FROM table_name LIMIT 10;

2. Using OFFSET and LIMIT for pagination:

SELECT * FROM table_name LIMIT 10 OFFSET 20;

3. In ORM (e.g., SQLAlchemy in Python), you can use the limit() and offset() methods:

query = session.query(Model).limit(10).offset(20)
results = query.all()

4. In Django ORM:

results = Model.objects.all()[:10]  # first 10 records

5. Through parameters in API or drivers — some libraries allow setting a limit when executing a request.

Thus, the limit is usually set at the SQL query level or using ORM tools, which allows effectively limiting the amount of data retrieved from the database.
