I would like to know how to perform pattern search using JDatabase

Here's my code:

$query->where($db->quoteName('Common_name').' LIKE '. $db->quote('\'o%\''));
$result = $db->loadResult();
  • The Joomla Documentation recommends using the 2nd parameter on both quote() and escape() when escape is nested inside of quote. This is to avoid performing double escaping. joomla.stackexchange.com/a/22712/12352 Commented Apr 19, 2018 at 22:00

try this

$db = JFactory::getDbo();
$query = $db->getQuery(true);

  ->where($db->qn('Common_name').' LIKE '. $db->quote($db->escape('o%')));

$results = $db->loadObjectList(); // use loadResult() for single value result

Documentation is your best friend: https://docs.joomla.org/Accessing_the_database_using_JDatabase

  • it produced an error 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 'WHERE LIKE' at line 3 SQL=SELECT Common_name FROM WHERE LIKE
