问题 Table data: I have a table cpu with the columns name, price, id, mark, value Data format: The price value is $xxx.xx and the mark value is xxxxxx both stored as VARCHAR(255)'s.

问题 I have written two small functions in Python to call mysqldump and mysql from console, so I am able to create a database backup and then restore it: # Makes a backup current database status def backupDatabase(): if(os.path.exists('myDatabaseBackup.sql')): os.remove('myDatabaseBackup.sql') call(['mysqldump', '-u myUsername myDatabase > myDatabaseBackup.sql']) # Restores database def restoreDatabase(): call(['mysql', '-u myUsername myDatabase < myDatabaseBackup.sql']) Nevertheless, they are not

问题 I have a very strange situation that I can't figure out what's wrong. I'm working on a Django project and I: Installed MySQL on OS X Added the DATABASES values: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'OPTIONS': { 'read_default_file': '/path/to/my.cnf', }, } } But then Django/Mezzanine tells me that there's an error loading MySQLdb module. So I Googled for some tips around this and tried these methods: pip install mysql-python Reinstalled pip Downloaded ez_setup.py

问题 For certain purposes I had to change field collations from utf8_unicode_ci to utf8_bin in a database. It turned out that the change lead to changes in datatypes that come to python. The question is how to force mysql-python to return unicode objects to python . Here is a sample that shows the problem (explicit charset forces use_unicode=1): >>> con = MySQLdb.connect(..., charset='utf8') >>> c = c.cursor() >>> c.execute('SELECT %s COLLATE utf8_bin', u'м') 1L >>> c.fetchone() ('\xd0\xbc',) >>>
