Issue details : #18935

We are introducing a new keyword FETCH FIRST N ROWS ONLY which can be used in presto queries. The keyword will work in sql queries just like LIMIT keyword to limit the number of rows returned from an sql select query.

For Example : select * from table FETCH FIRST 3 ROWS ONLY will return only 3 rows as a result of the sql query.
