Python pymysql datetime.datetime元组到时间戳

Question

I have code that selects the max timestamp from a MySQL db as follows:

cursor = connection.cursor()
cursor.execute("SELECT max(played_at) FROM 
testDB.Log;")
max_date = cursor.fetchall()

it returns a datetime.datetime object like this:

((datetime.datetime(2019, 6, 4, 11, 44, 5),),)

I need it to return a timestamp in the format %Y-%m-%d %H:%M:%S

I have tried using strptime(), datetime(), and strftime() but each time I get the error "tuple has no object (insert one of the three)"

How can I get the format i want?

Answer 1

The cursor is returning the database row as a tuple , you need to access individual columns values using square bracket notation. Columns are indexed from 0.

example:

print(max_date[0].strftime('%Y-%m-%d %H:%M:%S'))

Additionally cursor.fetchall() returns a list of tuples. You could use cursor.fetchone() in this particular instance given select(max) would always return one row.
