mysql-python

问题 I'm currently doing this: cursor.execute('SELECT thing_id, thing_name FROM things') things = []; for row in cursor.fetchall(): things.append(dict([('thing_id',row[0]), ('thing_name',row[1]) ])) Is there some shorthand I can use to do this, or should I write a little helper function? 回答1: Using list comprehension: things = [{'thing_id': row[0], 'thing_name': row[1]} for row in cursor.fetchall()] or using list comprehension with zip: things = [dict(zip(['thing_id', 'thing_name'], row)) for row

问题 I store the MySQL Compress function to insert compressed blob data to the database. In a previous question I was instructed to to use func.compress ( mysql Compress() with sqlalchemy ) The problem now is that I want to read also the data from the database. In mysql I would have done SELECT UNCOMPRESS(text) FROM ... probably I should use a getter in the class. I tried to do somethin like: get_html(self): return func.uncompress(self.text) but this does not work. It returns an sqlalchemy.sql

问题 We're trying to have a custom User model and behaviors, but then we noticed that even the default Django installation has issue when adding a new User via the Django Admin: The issue happens even in other Django versions (tried it in Django 1.8 , and w/ the latest one, Django 1.11.3 ).

Editing existing uses like the previously created

'NAME': 'mydatabase', # Or path to database file if using sqlite3. 'USER': 'myname', # Not used with sqlite3. 'PASSWORD': 'mypassword', # Not used with sqlite3. 'HOST': '', # Set to empty string for

问题 Is it okay to use a single MySQLdb connection for multiple transactions without closing the connection between them? In other words, something like this: conn = MySQLdb.connect(host="1.2.3.4", port=1234, user="root", passwd="x", db="test") for i in range(10): try: cur = conn.cursor() query = "DELETE FROM SomeTable WHERE ID = %d" % i cur.execute(query) cur.close() conn.commit() except Exception: conn.rollback() conn.close() It seems to work okay, but I just wanted to double check. 回答1: I think

问题 I am accessing a MySQL database from python via MySQLdb library.
