CREATE TABLE people (People_ID INT, Name TEXT, Country TEXT, Is_Male TEXT, Age INT)
CREATE TABLE church (Church_ID INT, Name TEXT, Organized_by TEXT, Open_Date INT, Continuation_of TEXT)
CREATE TABLE wedding (Church_ID INT, Male_ID INT, Female_ID INT, Year INT)

I want to see trend of the number of open date by open date
SELECT Open_Date, COUNT(Open_Date) FROM church
SELECT "Open_Date", COUNT("Open_Date") FROM "church"
