script how to get last backup to restore from AZURE

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\[email protected]' , 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

                    --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
