Esteban K  ber is absolutely right   Maybe one additional hint for bloody beginners like me  If you speciify the variables with  s  you have to follow this principle for EVERY input value  which means for the SET-variables as well as for the WHERE-variables   Otherwise  you will have to face a termination message like  You have an error in your SQL syntax  check the manual that corresponds to your MySQL server version for the right syntax to use near   s WHERE

It should be   cursor execute         UPDATE tblTableName    SET Year  s  Month  s  Day  s  Hour  s  Minute  s    WHERE Server  s       Year  Month  Day  Hour  Minute  ServerID     You can also do it with basic string manipulation   cursor execute   UPDATE tblTableName SET Year  s  Month  s  Day  s  Hour  s  Minute  s WHERE Server   s       Year  Month  Day  Hour  Minute  ServerID     but this way is discouraged because it leaves you open for SQL Injection  As it s so easy  and similar  to do it the right waytm  Do it correctly    The only thing you should be careful  is that some database backends don t follow the same convention for string replacement  SQLite comes to mind

Neither of them worked for me for some reason   I figured it out that for some reason python doesn t read  s  So use     instead of  S in you SQL Code   And finally this worked for me      cursor execute   update tablename set columnName       where ID           test4   4       connect commit

Here is the correct way   import MySQLdb  if   name         main         connect   MySQLdb connect host  localhost   port 3306                                user  xxx   passwd  xxx   db  xxx   charset  utf8        cursor   connect cursor        cursor execute            UPDATE tblTableName        SET Year  s  Month  s  Day  s  Hour  s  Minute  s        WHERE Server  s           Year  Month  Day  Hour  Minute  ServerID        connect commit       connect close     P S  Don t forget connect commit    or it won t work
