    Description

      I have a suggestion regarding the documentation for the OFFSET and FETCH FIRST documentation. On these documents, we have three SQL examples on the usage of these clauses. I suggest that we add a brief description of what each clause does.

      This might help the users to have a better understanding at first of how the said clauses work.

      Here are the examples with a possible description:

      – This query fetches the first row from T
      SELECT * FROM T FETCH FIRST ROW ONLY;

      – This query skips the first 10 rows and fetches the following 10.
      – It will fetch rows 11 through 20 (inclusive) from the table T, sorted by I
      SELECT * FROM T ORDER BY I OFFSET 10 ROWS FETCH NEXT 10 ROWS ONLY;

      – This query skips the first 100 rows from T.
      – If the table has less than 101 records, then an empty result set is returned.
      SELECT * FROM T OFFSET 100 ROWS;
