FIRST
and LAST
are very similar functions. Both are aggregate and analytic functions that operate on a set of values from a set of rows that rank as the FIRST
or LAST
with respect to a given sorting specification. If only one row ranks as FIRST
or LAST
, then the aggregate operates on the set with only one element.
Refer to FIRST for complete information on this function and for examples of its use.
