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

Give me the trend about the number of church opening in each year, and display X-axis from low to high order.
SELECT Open_Date, COUNT(Open_Date) FROM church GROUP BY Open_Date ORDER BY Open_Date
SELECT "Open_Date", COUNT("Open_Date") FROM "church" GROUP BY "Open_Date" ORDER BY "Open_Date"
