Magento MySQL connection close necessary

Question

I have opened MySQL database connection using the code below

Mage::getSingleton('core/resource')->getConnection('core_write');

Do I need to close this mysql connection on my own or the Magento handles it by default?

Answer 1

Answer 2

No, you do not have to close it.
