LIMIT and OFFSET are clauses used in SQL to limit the number of rows returned by a query and to specify the starting row for the result set.
LIMIT clause is used to limit the number of rows returned by a query. It is followed by an integer value that specifies the maximum number of rows to be returned. For example, "SELECT * FROM table_name LIMIT 10" will return only the first 10 rows from the table.
OFFSET clause is used to specify the starting row for the result set. It is followed by an integer value that specifies the number of rows to be skipped before starting to return the result set. For example, "SELECT * FROM table_name LIMIT 10 OFFSET 20" will return rows 21-30, skipping the first 20 rows.
Together, LIMIT and OFFSET can be used to paginate results, allowing the user to view a subset of the data at a time.
