Question

I have a column “date” and its format (Y-m-d -time). I need to create a new column using a SQL query and it will be the same with “date” column but it’s format will be (Y-m-d) only not with hours etc.

And I want to group them with GROUP BY. How can I write this query? I have to create a temporary column to see them grouped.

Answer 1

use DATE_FORMAT

SELECT DATE_FORMAT(columnName, '%Y-%m-%d')
