CREATE TABLE table_40499 ("Date" CLOB, "Score" CLOB, "Set 1" CLOB, "Set 2" CLOB, "Set 3" CLOB, "Set 4" CLOB, "Set 5" CLOB, "Total" CLOB)

What is Set 2, when Score is 3-0, when Date is May 11, and when Set 1 is 25-20?
SELECT "Set 2" FROM table_40499 WHERE "Score" = '3-0' AND "Date" = 'may 11' AND "Set 1" = '25-20'
SELECT "Set 2" FROM "table_40499" WHERE "Date" = 'may 11' AND "Score" = '3-0' AND "Set 1" = '25-20'
