Hi,
Can any one help me please
I have a column called Drive in a table A
Contents of the table A are as described below.
Drive
------
K:\Backups\Differential\development.bak
-------------------------------------------------------------------
@Database=Test, @FileName=K:\BackupS\Differential\Test\Test_Diff_2007-07-12-220004.bak, @FileNumber=0, @Desc=Backup differential database of Reports on 7/12/2007 10:00:04 PM, @BackupName=Backup differential database of Test, @RetainDays=1, @Init=1, @Priority=0, @With=DIFFERENTIAL, @Logging=0, @Affinity=255, @MaxTransferSize=1048576, @Throttle=50, @BufferCount=20, @CompressionLevel=4, @OLRMAP=0
----------------------------------------------------------------------
I need to write a select statement which should give me output like this
Drive
-------------
K:\Backups\Differential\development.bak
-------------
K:\BackupS\Differential\Test\Test_Diff_2007-07-12-220004.bak
Both of the rows which i had described above are two rows in a single column.
Can any one please help me with the code.
Thanks in advance,
Thank You,

You can use SUBSTRING & CHARINDEX functions to retrieve the data.

The example is as below:

declare @aa nvarchar(100) = '@Database=Test, @FileName=K:\BackupS\Differential\Test\Test_Diff_2007-07-12-220004.bak, @FileNumber'

select SUBSTRING(@aa, Charindex('K:', @aa), charindex('.bak', @aa) - (Charindex('K:', @aa)-4))

It returns:

K:\BackupS\Differential\Test\Test_Diff_2007-07-12-220004.bak

Thanks

SQL2k8, if the above didn't help you, can you make that into a CREATE TABLE and INSERT statement for us, so we can see exactly what you're seeing?

Details are in the comments in the code...

--===== Create a test table. This is NOT a part of the solution.

CREATE TABLE TableA

(

Drive VARCHAR(1000)

)

;

--===== Populate the test table. Notice the different drive letters.

-- Again, this is NOT a part of the solution.

INSERT INTO TableA

SELECT 'K:\Backups\Differential\development.bak' UNION ALL

SELECT '@Database=Test, @FileName=K:\BackupS\Differential\Test\Test_Diff_2007-07-12-220004.bak, @FileNumber=0, @Desc=Backup differential database of Reports on 7/12/2007 10:00:04 PM, @BackupName=Backup differential database of Test, @RetainDays=1, @Init=1, @Priority=0, @With=DIFFERENTIAL, @Logging=0, @Affinity=255, @MaxTransferSize=1048576, @Throttle=50, @BufferCount=20, @CompressionLevel=4, @OLRMAP=0' UNION ALL

SELECT '@Database=Test, @FileName=Z:\BackupS\Differential\Test\Test_Diff_2007-07-13-001015.bak, @FileNumber=0, @Desc=Backup differential database of Reports on 7/12/2007 10:00:04 PM, @BackupName=Backup differential database of Test, @RetainDays=1, @Init=1, @Priority=0, @With=DIFFERENTIAL, @Logging=0, @Affinity=255, @MaxTransferSize=1048576, @Throttle=50, @BufferCount=20, @CompressionLevel=4, @OLRMAP=0'

;

--===== Making the terrible assumption that all backup files will have the extension of ".bak",

-- find the full drive:\path\filename.bak no matter what the drive letter is.

SELECT SUBSTRING(Drive,PATINDEX('%[A-Z]:\%',Drive),CHARINDEX('.bak',Drive)+4-PATINDEX('%[A-Z]:\%',Drive))

FROM TableA

;

It's a "newbie" forum mistake. His first post where the OP said "Thank You very much. Your code works " was in reference to your good code. His second post of "the below code also works " was in reference to my code because my code is physically below your code on this thread.

Hi

Just a hint, if you are doing backup monitoring instead of using output from funny programs and try to format them.

Checkout msdb

backupset

backupmedia

backupmediafamily

Even if you use 3rd party apps, these tables still hold the info for the dates backed up, location and times.

It also populates that GUI that says, "last backup date"

Cheers
