Dynamic-SObject-Query

Map<String, Schema.SObjectField> fieldMap = Schema.SObjectType.<<Object_API_Name>>.fields.getMap();
//constructing a set of fieldnames
Set<String> keySet = fieldMap.keySet();
String soql = 'SELECT ';
for(String x : keySet) {
    //this might be avoidable - will look at it in later version but currently pulls in the API Field name
    Schema.DescribeFieldResult r = fieldMap.get(x).getDescribe();
    
    //appending the fieldname to the query string
    soql += r.getName() + ', ';
}
//removing the extra comma and space from the end of the query
soql = soql.substring(0, soql.length()-2);
// providing the name of the SObject and any additional clauses
soql += ' FROM <<Object_Api_Name>>';

 <<Object_Api_Name>> template = (<<Object_Api_Name>>)Database.query(soql);
