Can you tell me the highest DCSF number that has the Name of field, and the Ofsted number larger than 117160?
CREATE TABLE "central_watford_west_watford_and_oxhey" (
  "name" text,
  "faith" text,
  "type" text,
  "intake" real,
  "dcsf_number" real,
  "ofsted_number" real
);
SELECT MAX("dcsf_number") FROM "central_watford_west_watford_and_oxhey" WHERE "name"='field' AND "ofsted_number">117160;
