I was going through some sample codes around the web, and found that backticks (`) are sometimes used to enclose the table names and field names we used in the queries in DataObject:get and DataObject:get_one methods. For example:
$test = DataObject::get_one("Entity", "`Code`='".$data['Code']."'");
What is the significance of enclosing the table names and filed names with backticks? I red some other sample codes in which no backticks are used. Is this something outdated now?
