script how to get last backup to restore from AZURE - sql-server

Question

I want to restore the last backup from mu AZURE server. I have one script but just I achieve to take the backup with current date but not the last one. Do you have any idea how to get it?
`USE [master]
GO
DECLARE #name VARCHAR(50) -- database name
DECLARE #URL VARCHAR(256) -- URL for backup
DECLARE #fileDate VARCHAR(20) -- used for file date
-- specify date format to take the last backup.
SELECT #fileDate = REPLACE (CONVERT (VARCHAR (10), GETDATE (), 120), '-','_')
--Create a credential to connect to the windows azure storage service
IF NOT EXISTS (SELECT * FROM sys.credentials WHERE credential_identity = 'aaaaaaaaaa')
BEGIN
CREATE CREDENTIAL Pyramidsqlcredential WITH IDENTITY = 'bbbbbbbbbb'
,SECRET = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
END
GO
--Code to be able to restore specific databases
DECLARE db_cursor CURSOR FOR
SELECT name
FROM master.dbo.sysdatabases
WHERE name IN ('STG','DWH','AUXDB','TESTPORTAL') -- only restore these databases
OPEN db_cursor
FETCH NEXT FROM db_cursor INTO #name
WHILE ##FETCH_STATUS = 0
BEGIN
--Creation of PRE databases
IF OBJECT_ID(N'PRE_#name', N'U') IS NOT NULL
DROP DATABASE #name;
GO
CREATE DATABASE [#name]
CONTAINMENT = NONE
ON PRIMARY
( NAME = N'PRE_#name', FILENAME = N'G:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\Data\PRE_#name.mdf' , SIZE = 609344KB , MAXSIZE = UNLIMITED, FILEGROWTH = 1024KB ),
FILEGROUP [INMEMORY] CONTAINS MEMORY_OPTIMIZED_DATA DEFAULT
LOG ON
( NAME = N'PRE_#name', FILENAME = N'H:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\Data\PRE_#name_log.ldf' , SIZE = 833024KB , MAXSIZE = 2048GB , FILEGROWTH = 10%)
set #URL = 'https://xxxxxxxxxx.blob.core.windows.net/'
--RESTORE the database to the windows azure storage service - blob using URL
RESTORE DATABASE PRE_AUXDB
FROM URL = #URL+#name+'/'+#name+''+#fileDate+'*.bak'
--FROM URL = 'https://xxxxxxxxxxxxxxxxxxxxxxx.blob.core.windows.net/AUXDB/AUXDB'+REPLACE (CONVERT (VARCHAR (10), GETDATE (), 120), '-','_')+'*.bak'
WITH CREDENTIAL = 'aaaaaaaaaaaaaaa'
,MOVE 'PRE_AUXDB_Data' to 'G:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\Data\PRE_#name_Data.mdf'
,STATS = 10
END
CLOSE db_cursor
DEALLOCATE db_cursor`

I think I found a solution. the script is not tested yet. Perhaps it helps to someone.
USE [master]
GO
DECLARE #name VARCHAR(50) -- database name
DECLARE #URL VARCHAR(256) -- URL for backup
--Create a credential to connect to the windows azure storage service
IF NOT EXISTS (SELECT * FROM sys.credentials WHERE credential_identity = 'credentialname')
BEGIN
CREATE CREDENTIAL credentialname WITH IDENTITY = 'introduceyouridentity'
,SECRET = 'accountkey'
END
GO
--Code to be able to restore specific databases
DECLARE #db_cursor CURSOR
SET #db_cursor = CURSOR FOR
SELECT name
FROM master.dbo.sysdatabases
WHERE name IN ('STG','DWH','AUXDB','TESTPORTAL') -- only restore these databases
OPEN #db_cursor
FETCH NEXT FROM #db_cursor INTO #name
WHILE ##FETCH_STATUS = 0
BEGIN
declare #backupfile as Varchar(255) --latest bck in AZURE
declare #DBname VARCHAR(50) = 'PRE_'+#name --name new database ex: PRE_AUXDB
--Check latest backup file in Azure per type
/* type char(1)
Backup type. Can be:
D = Database
I = Differential database

SELECT TOP 1 #backupfile=mf.physical_device_name from msdb..backupset bk
join msdb..backupmediafamily mf on bk.media_set_id = mf.media_set_id
where database_name=#name and bk.type='D' order by
backup_set_id desc
