SQL Server # Moving MASTER database in cluster environment

Few months back I have wrote post about moving MASTER and MSDB database to new location in stand alone machine.
In recent past we had a situation where customer asked us to move MASTER database to new location, below are the steps I have taken:

1.     Connect to the Server
2.     Open Configuration Manager -> SQL Server Service
3.     Right Click and say Properties
4.     Click on the Start-up Parameter
5.     Remove start-up parameter (the highlighted one)

  -dOLDLocation\master.mdf
  -eOLDLocation\ErrorLog
  -lOLDLocation\mastlog.ldf

      6.     Add new start-up parameters with new values (per your configuration)

  -dNewLocation\master.mdf
  -eNewLocation\ErrorLog
  -lNewLocation\mastlog.ldf

      7.    Check and confirm which node is active
      8.    PAUSE current PASSIVE Node  to avoid fail-over
      9.    Take SQL Server resources offline, i.e. SQL Server, SQL Agent, MSDTC, SQLCLUSTER Name (do not take SQL Cluster IP Offline)
    10.    Copy MASTER.MDF and MASTLOG.LDF to NEW Location ( S:\SQLDATA, yours could be different)
    11.    Log into Cluster Administrator and bring SQL Server Resources online
    12.    Resume current PASSIVE Node


That's all, you should be able to see your master database on new location now!!!

SSRS # How to achieve Dynamic Sorting in SSRS?

Introduction
I wrote a blog on “Dynamic Sorting” in SSRS sometime back. Even though I successfully achieved sorting the data dynamically, I failed to find out a way of applying the “Sort Direction” dynamically as the Sort Direction did not accept an expression to manage it.
Recently, I came across a trick which solves this very easily purely in SSRS. Let’s jump on to the implementation now without wasting much time.
Implementation
Continuing with the same example of sorting 3 columns – Col1,Col2 & Col3 in any preferred order, we can specify the Sort Direction dynamically in the following way -
1. Define 3 additional parameters - @Col1SortDirection,@Col2SortDirection & @Col3SortDirection of STRING type.
2. While setting the Sort Options for Tablix or Group, we have to define sorting for double the number the sorting columns as under -








The Sort By expressions will be defined as under -
a. IIF(Parameters!Col1SortDirection.Value = "Ascending",Fields(Parameters!SortCol1Name.Value).Value,Nothing)
b. IIF(Parameters!Col1SortDirection.Value = "Descending",Fields(Parameters!SortCol1Name.Value).Value,Nothing)
c. IIF(Parameters!Col2SortDirection.Value = "Ascending",Fields(Parameters!SortCol2Name.Value).Value,Nothing)
d. IIF(Parameters!Col2SortDirection.Value = "Descending",Fields(Parameters!SortCol2Name.Value).Value,Nothing)
e. IIF(Parameters!Col3SortDirection.Value = "Ascending",Fields(Parameters!SortCol3Name.Value).Value,Nothing)
f. IIF(Parameters!Col3SortDirection.Value = "Descending",Fields(Parameters!SortCol3Name.Value).Value,Nothing)
Note: we can use any CONSTANT value to replace Nothing used in above expression.
3. Pass the required Sort Direction, say - @Col1SortDirection = “Ascending”, @Col2SortDirection = “Descending” & @Col3SortDirection = “Ascending” or in any preferred value.
4. Pass the values for other parameters as explained in my last post.
Conclusion
With this we can now easily control the dynamic sorting with full flexibility of specifying the Column Names & the Sort Direction both dynamically using pure SSRS.
Hope, this will help you a lot!

SQL Server # Database Backup Report using T-SQL

Today, I am going to share few very useful scripts which will report us on Database Backup from different view points.

To get the List/History/Log of all the Successful Backups

SELECT 

  b.machine_name,

  b.server_name,

  b.database_name as DBName,

  b.backup_start_date,

  b.backup_finish_date,

  CASE 

    WHEN b.[type] = 'D' THEN 'Database'

    WHEN b.[type] = 'I' THEN 'Differential database'

    WHEN b.[type] = 'L' THEN 'Log'

    WHEN b.[type] = 'F' THEN 'File or filegroup'

    WHEN b.[type] = 'G' THEN 'Differential file'

    WHEN b.[type] = 'P' THEN 'Partial'

    WHEN b.[type] = 'Q' THEN 'Differential partial'

    ELSE b.[type]

  END Backup_Type,    

  b.expiration_date,

  b.[user_name],

  DATEDIFF(MINUTE,b.backup_start_date ,b.backup_finish_date) as Total_Time_in_Minute,

  b.recovery_model,
