Order by Month-year in Snowflake

Question

I have a table with following sample output;

Act_ID  |  STATUS  | Year-Month
123     |  a       | 2020-Dec
120     |  a       | 2020-May
124     |   b      | 2021-Feb

Is it possible to order it as per time; we want the following output;

Desired Output

Act_ID  |  STATUS  | Year-Month
120     |  a       | 2020-May
123     |  a       | 2020-Dec
124     |   b      | 2021-Feb

But when we try to order by this column, it is sorting it alphabetically.

SELECT *
FROM table
ORDER BY Year-Month;

Actual Output

Act_ID  |  STATUS  | Year-Month
123     |  a       | 2020-Dec
124     |  b       | 2021-Feb
120     |   a      | 2020-May

Answer 1

Convert the value to a date:

order by to_date(year_month, 'YYYY-MON')
