Table schema:
CREATE TABLE table_name_36 (year INTEGER, score_in_final VARCHAR, championship VARCHAR, outcome VARCHAR)

Question: What is the sum of Year(s), when Championship is "Australian Open", when Outcome is "Runner-Up", and when Score in Final is 3-6, 6-3, 6-2?
SQL: SELECT SUM(year) FROM table_name_36 WHERE championship = "australian open" AND outcome = "runner-up" AND score_in_final = "3-6, 6-3, 6-2"
