Other than SOQL or SOSL, Custom settings have their own set of methods to access the record.

For example:If there is custom SETTING of name ISO_Country,

SO_Country__c code = ISO_Country__c.getInstance(‘INDIA’);

//To RETURN a map of data SETS defined for the custom OBJECT (all records in the custom object), //you would use:

Map<String,ISO_Country__c> mapCodes = ISO_Country__c.getAll();

// display the ISO code for India

System.debug(‘ISO Code: ‘+mapCodes.get(‘INDIA’).ISO_Code__c);

//Alternatively you can return the map as a list:

List<String> listCodes = ISO_Country__c.getAll().values();
