Error using convert MySQL in Python I'm practically newbie with MySQL.
I'm trying to do a query to retrieve a preformatted date, obtained from a subtraction, using CONVERT. 
This is the query:

sql = f"SELECT CONVERT(timestamp - {sqlToday}, getdate(), 23), count_issue FROM total_unresolved_issue WHERE project = '{project}'"


timestamp is a column of the database, and sqlToday is a date in format datetime.date(2020, 2, 13). 
Unfortunately this error returns, and I don't know how to handle it:


  mysql.connector.errors.ProgrammingError: 1064 (42000): You have an
  error in your SQL syntax; check the manual that corresponds to your
  MariaDB server version for the right syntax to use near 'getdate(),
  23), count_issue FROM total_unresolved_issue WHERE project = 'Graphic'
  at line 1


Thanks in advance!
In fact, it is not easy to find the right command we need for queries in the MySQL documentation. 
However, by testing, I saw that this should be fine:

sql = f"SELECT DATEDIFF(NOW(), timestamp), count_issue FROM total_unresolved_issue WHERE project = '{project}'"


DATEDIFF(NOW(), timestamp) returns the difference between two dates in days.
