# ORACLE/PLSQL - NVL(A, B) EXAMPLES
# If A IS NULL substitute with B

# Example 1. if table b contains values that over-write values in table a

SELECT NVL(b.name, a.name) AS name FROM a left join b on a.id = b.id;

# Example 2. to replace NULL values with an alternative placeholder value

SELECT NVL(a.name, 'Unnamed') AS name FROM a;

/* https://puzzling.stackexchange.com/questions/60942/biggest-army-on-a-chessboard

Reminder
Everybody knows that we can place 8 queens in a chessboard without threatening each other (see There). same reasonment can be made for knights, bishops, rooks and kings. Giving respectively 32 knights, 14 bishops, 8 rooks, and 16 kings.
Problem
If we assign to each type of piece a value invertly proportionnal of the number of this we can place. It means Knights = 1/32. Bishop = 1/14. Rook = 1/8. Queen =1/8 and King = 1/16.

What is the best sum value we can achieve mixing these pieces still with none able to take each other?*/
