The FIRST_VALUE
function returns the value from the first row in a window.
The default behavior is RESPECT NULLS
. If the IGNORE NULLS
option is specified, the function returns the first non-null row in each window (assuming one exists, null
otherwise).
This example computes the number of games played by a player in their first year.
Output:
playerName | yearID | numberOfGames | EXPR$3 |
