Mysql unable to select datetime column

I’m trying to SELECT rows that matches datetime in my column. I have a table containing mDTS set as DATETIME (with no curly braces).
My table looks something like this:

CREATE TABLE tb_cyc (
  mID int(11) UNSIGNED NOT NULL AUTO_INCREMENT COMMENT 'ID cycle',
  mDTS datetime DEFAULT CURRENT_TIMESTAMP COMMENT 'Data inizio ciclo',
  mDTE datetime DEFAULT '0000-00-00 00:00:00' COMMENT 'Data fine ciclo',
  PRIMARY KEY (mID)
)

I’m trying to run the following query but it returns an empty set.

SELECT * FROM tb_cyc WHERE mDTS = '12/08/2021 10:42:34'

I’ve also tried:

SELECT * FROM tb_cyc WHERE mDTS LIKE '12/08/2021 10:42:34'

and

SELECT * FROM tb_cyc WHERE mDTS = '12/08/2021 %'

But none of this seems to work.
What am I doing wrong?

Method 1

Change the format of the date in WHERE clause:

WHERE mDTS = '2021-08-12 10:42:34'

What happens is that mDTS is a datetime; when compared with a string MySQL will treat the string as a date/time. The literal value 12/08/2021 10:42:34 will generate the following warning:

Incorrect datetime value: '12/08/2021 10:42:34' for column 'mDTS' at row 1
