Show the trend about the frequency of the claim dates, and I want to order in desc by the X.
SELECT Date_Claim_Settled, COUNT(Date_Claim_Settled) FROM Settlements GROUP BY Date_Claim_Settled ORDER BY Date_Claim_Settled DESC
SELECT "Date_Claim_Settled", COUNT("Date_Claim_Settled") FROM "Settlements" GROUP BY "Date_Claim_Settled" ORDER BY "Date_Claim_Settled" DESC
