Python MYSQL 更新语句

我试图让这个 Python MYSQL 更新语句正确（带变量）：

cursor.execute ("UPDATE tblTableName SET Year=%s" % Year ", Month=%s" % Month ", Day=%s" % Day ", Hour=%s" % Hour ", Minute=%s" Minute "WHERE Server=%s " % ServerID)   

有什么想法我哪里出错了吗？

It 应该:

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用基本的字符串操作来做到这一点，

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 way^tm. Do it correctly.

您唯一应该小心的是，某些数据库后端不遵循相同的字符串替换约定（例如 SQLite）。
