How to use the lazy.first function in lazy

executeQuery: function(sql, options){
			// executes a query with provide start and end parameters, calculating the total number of rows
			if(options){
				if(typeof options.start === "number"){
					var countSql = sql.replace(/select.*?from/i,"SELECT COUNT(*) as count FROM");
					if(typeof options.end === "number"){
						sql += " LIMIT " + (options.end - options.start + 1);
					}
					sql += " OFFSET " + options.start;
					var results = this.executeSql(sql, options.parameters).rows;
					var lengthObject = first(this.executeSql(countSql, options.parameters).rows);
					
					results.totalCount = lengthObject.count;
					return results; 
				}
			}
			var results = this.executeSql(sql, options.parameters).rows;
			results.totalCount = results.length;
			return results; 			
		},
