CREATE TABLE table_name_51 (co_champions NUMBER, records VARCHAR2, pct VARCHAR2, mrc_championships VARCHAR2)

What is the highest value for co-champions when the PCT is less than 0.786 and MRC championships is 6 with records of 88-45-6?
SELECT MAX(co_champions) FROM table_name_51 WHERE pct < 0.786 AND mrc_championships = 6 AND records = "88-45-6"
SELECT MAX("co_champions") FROM "table_name_51" WHERE "88-45-6" = "records" AND "mrc_championships" = 6 AND "pct" < 0.786
