Select the latest year in a column using SQL query

Question

I have a dataframe like this

Value.	Date
A	08/08/2009
A	09/12/2021
A	05/10/2022
A	06/09/2022
A	07/08/2022

I need output like

VALUE	DATE
A	05/10/2022
A	06/09/2022
A	07/08/2022

We have to print a latest year with all month data present in the date column.please refer output table.

i used SQL query like

Select Top 10 * from table where Order by (Date) DESC;

The max() select only one date so that didn't help me

But didn't get expected answer. Can please someone help me with the query?

Answer 1

You can just use MAX in a subquery, this will produce the intended outcome you have shown in your question:

SELECT yourcolumn
FROM yourtable
WHERE 
YEAR(yourcolumn) = (SELECT MAX(YEAR(yourcolumn)) FROM yourtable);

The latest year is 2022, so MAX in the subquery will find this year and the whole query will select all dates in 2022.

Answer 2

SELECT *
FROM tablename
WHERE datecolumn >= (SELECT DATE_FORMAT(MAX(datecolumn), '%Y-01-01')
                     FROM tablename)

To improve this query you'd have an index by datecolumn (or where this column is an expression prefix).
