RunningValue Function (Reporting Services) – Calculating Running Totals

In one of my previous posts I talked about Calculating Running Totals in T-SQL.  Now I will show you how you can calculate the running totals in Sql Server Reporting Services(SSRS).  Yes, it is very much possible with RunningValue function in SSRS and also very easy compare to doing it in SQL.  

The syntax for RunningValue function goes like this -

RunningValue(expression, function, scope)

• expression : The expression on which to perform the aggregation, for example, [Quantity].
• function : The name of the aggregate function to apply to the expression, for example- Sum.
• scope :The name of a dataset, data region, group or Nothing.

See the table below and RunningTotal column which is Cumulative SUM of Quantity column. 

ShipId	OrderId	ShipDate	Quantity	RunningTotal
1	1	2009-02-01 12:06:16.820	10	10
2	1	2009-02-02 16:16:16.820	15	25
3	2	2009-02-01 13:26:16.820	20	45
4	2	2009-02-03 17:40:16.820	12	57
5	2	2009-02-04 13:05:16.820	15	72
6	3	2009-02-03 14:25:16.820	25	97
7	3	2009-02-04 15:50:16.820	50	147
8	3	2009-02-05 19:40:16.820	30	177
9	4	2009-02-06 15:30:16.820	20	197
10	4	2009-02-07 16:20:16.820	10	207
11	5	2009-02-05 17:05:16.820	35	242

For achieving that in SSRS, add extra column in your Report’s Layout Page and put following expression in it-

=RunningValue(Fields!Quantity.Value, Sum, Nothing)

Yes, it is easy and simple, isn’t it?  But what about when you want the RunningTotals for group of records?  Like for above example you want the Running Totals for each orderId separately.  See the table below :

ShipId	OrderId	ShipDate	Quantity	RunningTotal
1	1	2009-02-01 12:06:16.820	10	10
2	1	2009-02-02 16:16:16.820	15	25
3	2	2009-02-01 13:26:16.820	20	20
4	2	2009-02-03 17:40:16.820	12	32
5	2	2009-02-04 13:05:16.820	15	47
6	3	2009-02-03 14:25:16.820	25	25
7	3	2009-02-04 15:50:16.820	50	75
8	3	2009-02-05 19:40:16.820	30	105
9	4	2009-02-06 15:30:16.820	20	20
10	4	2009-02-07 16:20:16.820	10	30
11	5	2009-02-05 17:05:16.820	35	35

Now for achieving that you need do followings :

• First go to Report Layout page and add a new Group.   Give some name to the group.  If you don’t gave any name the default name would be something like “table1_Group1”.  Just note that.  And add OrderId to “Group On” expression.
• Now change the expression at RunningTotal column as

  =RunningValue(Fields!Quantity.Value,SUM,"table1_Group1")

        Now if you have noticed I have replaced the scope Nothing to Group name “table1_Group1” .

Well after adding the extra group in the report you might see blank spaces after every  OrderId change. If you don’t want those blanks and want continuous report, then go to the property page of the new group added and set Visible to “false”.

Script All the Stored Procedures in The Database

In Sql Server 2005 and 2008 you can script the stored procedure in Management Studio by right clicking on Store Procedure name and clicking on “Script Store Procedure as” and then “Create To”.

But if you want to script all the Stored Procedures in the database programmatically, then here is the simple T-SQL query for it -

To script All the Stored Procedures in the Database :

SELECT    O.Name as ProcName         ,M.Definition as CreateScript         ,O.Create_Date         ,O.Modify_Date FROM sys.sql_modules as M INNER JOIN sys.objects as O ON M.object_id = O.object_id WHERE O.type = 'P'

If the Stored Procedure is created with ENCRYPTION option then you will get the NULL in the definition column.

Similarly,

To script All the Views in the Database :

SELECT    O.Name as ProcName         ,M.Definition as CreateScript         ,O.Create_Date         ,O.Modify_Date FROM sys.sql_modules as M INNER JOIN sys.objects as O ON M.object_id = O.object_id WHERE O.type = 'V'

To script All the Functions in the Database :

SELECT    O.Name as ProcName         ,M.Definition as CreateScript         ,O.Create_Date         ,O.Modify_Date FROM sys.sql_modules as M INNER JOIN sys.objects as O ON M.object_id = O.object_id WHERE O.type = 'FN'

For scripting all Triggers small modification is required, instead of sys.objects I joined the sys.triggers with sys.sql_modules.

To script All the Triggers in the Database :

SELECT    O.Name as ProcName         ,M.Definition as CreateScript         ,O.Create_Date         ,O.Modify_Date FROM sys.sql_modules as M INNER JOIN sys.triggers as O ON M.object_id = O.object_id

How To Split A Comma Delimited String

In one of my previous posts I wrote about “How to Create a Comma Delimited List”.  Now I’ll show you an example with reverse action, that is Splitting a Comma Delimited String or array() of values.

There can be different types of Delimiters also : like Comma ' , ', vertical bar ' | ', Single space or a Tab.

For example here is our Sample Table -

Id	AllNames
1	A,B,C
2	A,B
3	X,Y,Z

And here is the expected output -

Id	Names
1	A
1	B
1	C
2	A
2	B
3	X
3	Y
3	Z

Create Sample Data :

-- Create Table for  Sample Data CREATE TABLE Test ( ID INT, AllNames VARCHAR(100) ) GO -- Load Sample Data INSERT INTO test SELECT 1, 'A,B,C' UNION ALL SELECT 2, 'A,B'  UNION ALL SELECT 3, 'X,Y,Z' GO -- Verify the Sample Data SELECT Id, AllNames FROM Test

And here is the query for How to split a comma delimited string :

;WITH Cte AS (     SELECT         id,         CAST('<M>' + REPLACE( Allnames,  ',' , '</M><M>') + '</M>' AS XML) AS Names     FROM Test ) SELECT     ID,     Split.a.value('.', 'VARCHAR(100)') AS Names FROM Cte CROSS APPLY Names.nodes('/M') Split(a)

Acknowledgement : Well seriously don’t know.  Somewhere I came across this solution while answering / participating  on MSDN Sql Server Forums.  So credit goes to my fellow Moderators/answrers on MSDN Forums.

Actually whatever expertise I gained on T-SQL and Sql Server is by participating / answering to the posts on online forums.  I’m one of those freaks who hate to read books ;)
