How to change a value in the answer?
Hello!I got a database that looks like this in Oracle:
http://www.it-gymnasiet.info/programmering_c/databasebattle.jpg
I have to execute this question:
SELECT solider.solider_id, special_weapon.other
FROM solider, special_weapon
WHERE
special_weapon.solider_id = solider.solider_id
But when the special_weapon.other is null I have to replace that in the answer-column to "No data".
Does any one know how to do that?
Best regards
Fredrik
