CREATE TABLE table_name_26 (prev VARCHAR2, chng VARCHAR2, rating VARCHAR2)

Can you tell me the total number of Prev that has the Chng of +10, and the Rating larger than 2765?
SELECT COUNT(prev) FROM table_name_26 WHERE chng = "+10" AND rating > 2765
SELECT COUNT("prev") FROM "table_name_26" WHERE "+10" = "chng" AND "rating" > 2765
