# Handling NULL
+ Solution 1: Omit quotation marks for `NULL`
+ Solution 2: Use placeholders or `Prepared Statement`, for example in Python:
  + `cursor.execute('INSERT INTO test.mkd (title) values (%s)', (None))`
--------------------------------------------------------------------------
The best solution to this problem is to use placeholders. The Python API supports this, as shown in the third example in the slide. Placeholder substitution at run time automatically converts the Python type None into the equivalent SQL type, NULL. 

Note: This course covers prepared statements in the lesson titled "Prepared Statements".
