Hello Sergei!
Not for the same query. You can use a CAST or e.g. CONCAT, it'll force the column into a string type, for example:
SELECT CONCAT(MIN(NOW()))
Thanks for the hint, but unfortunately the actual application is not under my control. So I cannot change the query or how the result is treated. Best regards, Stefan On 03.07.19 10:02, Sergei Golubchik wrote:

Hi all,
If I execute the following query on MariaDB 10.1 or later, the result contains a column with a datetime field type (MYSQL_TYPE_DATETIME):
SELECT MIN(NOW()) AS t
On older versions or any version of MySQL this column is a text type (MYSQL_TYPE_VAR_STRING).

Is there a possibility to use the old behavior in newer version?
