Can I Create Dynamic Report Parameters?
Apr 4, 2007
Hi all,
Is it possible to create a report with dynamic parameters or parameters dependant on other ones? I have the following scenario -
Parameter 1 - 'Select an Application' - List of applications that are available
Parameter 2 - 'Select a module' - This is a list of modules that needs to depend on Parameter 1. As a user selects different applications, the appropriate module list will be loaded.
Is this possible to do in SSRS?
Thanks,
Brian

Hi,
I have a need to display on screen AND email a pdf report to email addresses specified at run time, executing the report with a parameter specified by the user. I have looked into data driven subscriptions, but it seems this is based on scheduling. Unfortunately for the majority of the project I will only have access to SQL 2005 Standard Edition (Production system is Enterprise), so I cannot investigate thoroughly.
So, is this possible using data driven subscriptions? Scenario is:
1. User enters parameter used for query, as well as email addresses.
2. Report is generated and displayed on screen.
3. Report is emailed to addresses specified by user.
Any tips on how to get this working?
Thanks

Hello,
I have a report that uses a begin date and an end date as paremeters along with a user's email adddress to generate thier schedule for the coming week. I would like to schedule this report to run at the beginning of the week and email to each user based on thier email address. So the parameters will be system.date +1 and system.date+6 and user email. I have the users email addresses in a table so the 3rd parameter could be a "for each email in table users...". Is this posssible? Should it be in Report services or a scheduled Stored Procedure? Any help with syntax will be greatly appreciated!
Thanks,
Bob Myles

I need to pass the out put from a stored procedure as an input parameter to another stored procedure. I created a data set for each stored procedure. Fron the second data set parameter tab, I added a parameter to refer to the field from the first data set.
I get the error Fiels can not be used in query parameter expressions.
I tried two simple queries instead of stored procedures with first query feeding the second query. I get the same error. Is there any other other way to accomplish this?
Thank You.

I found the following paragraph while searching on here:
************************************************************************
You could easily set up a parameter for each column and then display that column conditionally based on the parameter.
For instance, if you have a column that displays First Name, you could have a parameter called DisplayFirstName. Then in design view you'd select the whole FirstName column and in the Visibility-Hidden property set it to :
=iif( Parameters!DisplayFirstName.Value = false, true, false )
This could easily become a big, unwieldy report, though, if you have a great number of dynamic columns. Also, The width of the report is set at design time, and it includes the width of all your columns, not just the visible ones. This could cause you some pagination problems.
************************************************************************
That is exactly my problem. I have lots of dynamic columns which causes the width of the report to be wide. Thus even though at run time the report only shows columns within a page, the report itself consists of a lot of white spaces after the selected columns. Does anyone know a solution to this? If not, I guess creating the rdl with code manually is the only way? Please advise. Thanks in advance.

I'm trying to create report with datasource as a cube. I'm able to connect to datasource to pull data with a single parameter. But, I'm unable to succeed in creating a cascading parameter.
The following scenario:
I have a dimension "Period" as Paremeter.
The Period dimension is cascaded to year- quarter- month.
So, I would like to create a cascading parameter for period as year - quarter - month.
Please let me know, how to acheive this.
thanks,
Naveen.

I have a stored procedure that takes a date range and returns all the sales in that date range. I'm trying to create the report model for ad-hoc reporting. When I go to create the dataset view, it only lets me select tables or views.... how do I get around this?

I have a SSRS report with four parameters,and I want to be able to enter information for two of the parameters and run the report opposed to all four of them. However, when I select allow blanks and only select the parameters that I want to run the report by, the report come back blank..Essentially, I want to be able to the run report by different parameters without having to enter information for all parameters at the same time.

I have a report that i want to beable to do some dynamic paramaters on it. I have a start and end date of when they want to run the report but i also have a mulivalue list box for users filtering for users. I want to add a supervisor filter on form also. But I have a problem.
I want to allow the users to select a supervisor and filter for all employees under that, or allow them to select a set of users and allow them to filter for that also. Also i would like when they select no supervisor or user it just filters for the dates and picks all up all the users.
I thought i could do something like in access like this Like UserName & "*"
but it doesnt work.
Here is my dataset code i am using currently:
SELECT U.Name, A.row_date, A.split, A.SumOfti_stafftime, A.AHT, A.AvgACW, A.AvgACD, A.AvailTime, A.SplitSkill_Incalls, A.SplitSkill_Outcalls, A.SumOfacdtime,
A.SumOfti_othertime, A.SumOfacwtime, A.SumOfti_auxtime0, A.SumOfti_auxtime1, A.SumOfti_auxtime2, A.SumOfti_auxtime3, A.SumOfti_auxtime4,
A.SumOfti_auxtime5, A.SumOfti_auxtime6, A.SumOfti_auxtime7, A.SumOfti_auxtime8, A.SumOfti_auxtime9, U.Sup
FROM tblAvayaDaily AS A RIGHT OUTER JOIN
tblUsers AS U ON A.logid = U.[Avaya ID]
WHERE (A.split = 1651) AND (U.Name IN (@UserName)) AND (A.row_date BETWEEN @rDateStart AND @rDateEnd) OR
(A.split = 1655) AND (U.Name IN (@UserName)) AND (A.row_date BETWEEN @rDateStart AND @rDateEnd) OR
(A.split = 1653) AND (U.Name IN (@UserName)) AND (A.row_date BETWEEN @rDateStart AND @rDateEnd)

I am currently working on a project that involves creating dynamic insert and update statements for dynamically created tables. The tables I am creating the statements for could have up to 1000 columns.
Obviously building the entire insert/update SQL string dynamically in VB.Net and sending it to the Sql server leaves the system vulnerable to injection attack or error caused by single quotes in strings.
I am using the Patterns and Practices Data Application block for my data access.
What I am considering is creating the dynamic sql as a statement with the columns names and values in as parameters (@XXXXX) and then looping through my list of columns and values and adding them as by AddInParameters on the DbCommand.
- Can it handle such large amount of parameters at all?
- What kind of structure does ADO.net send to the SQL server? i.e. Will using so many parameters mean that the data communicated to the SQL server from the webserver by the parameter method would be much larger than the substituted dynamic sql string?
- How does ADO.NET/SQL Server 2005 perform with such large amounts of parameters on a DBCommand?
Any advice as to whether this is a viable way to proceed would be much appreciated.
Oh yeah... I am using VB.NET in VIsual Studio 2005 with a SQL Server 2005 DB.
Thanks
Mark

Here is he issue.
* We have a DAL that generates all SQL dynamically out of a nobject model. Standard very powerfull O/R mapper.
* In the DAL, for CRUD operations, we generate the statements dynamically. As an example, let's take INSERT.
* The insert is generated ONCE, with parameters, and cached. For every reuse, the parameters are replaced (in value), and the whole thing commited.
I see hte following negative: I can not easily batch multiple inserts. Parameters have to be unique per batch. So, if I want to batch two inserts, I need two sets of parameters.
Alternative:
Instead of generating the SQL with parameters, we generate the SQL as a string ready to be inserted for / with a String.Format, and then I encode the parameters and make one SQL String out of this. Now, please - don't say "sql injection", we are not that stupid, the layer handles this already, properly encoding all dangerous values.
With this approach, the SQL statement would be a string and not use any parameter. As a result, I could batch them up as much as I want (ok, up to a certain string size). I need to keep parameters around anyway (for blobs etc.), but most objects do not have blobs, and the SQL is prettty small. This small SQL could be batched significantly (100 statements per batch, propably mode) and be submitted to the database. As a result, the round trips to the databae would go down.
Now, my question is - which of the two approaches is more advisable, from a performance point of view? Again, stuff like SQL injection and ease of handling are totally irrelevant - the SQL never leaves the DAL and is generated in there, and we will go through a lot of complexitiy for higher performance.
Normally I would say batching should be better. SQL Server can auto-parameterize the statements (reusing the query plan), and / but the network round trips are the larger issue here.
Any comments on this?

Hi All,
I'm trying to write a formula (actually, four) which will be used in Panorama NovaView to allow a user to see Revenue (on rows) by Previous Month (Current Year), Previous Month (Previous Year), Current YTD (ending at month in question), Previous YTD (ending at month in question) (on columns -- not necessarily in that order).
Basically, when run anytime during November 2005, the output would look like:
2004 Total | Oct 2004 | 2005 Total | Oct 2005
$ 100,000 | 15,000 | 120,000 | 17,500
The Dimension I'm working with is [Calendar Year], with levels: (All), [Calendar Year], [Calendar Month], [Calendar Week].
I've been focusing on the formula for the first column, since it is the most complex (I think). Here's the jist of what I am trying to do:
SELECT Measures.Revenue ON ROWS,
<<Last Year>>.January : <<Last Year>>.<<LastMonth>> ON COLUMNS
FROM SalesCube
I believe some combination of PeriodsToDate(), LastPeriod() and/or <<Current Year>>.PrevMember & <<Current Month>>.PrevMember is what I need, but I just can't get the syntax right.
Any help would be appreciated.
Thanks,

Good day,
I have an issue on constructing dynamic WHERE conditions that use OPTIONAL parameters.
SP_SOMETHING (
1) @DateFrom datetime,
@DateTo datetime,
2) @Param1 char(8),
3) @Param2 char(3),
4) @Param3 tinyint
)
I would like to use a where clause that can make use of any combination of the 4 parameters (the two dates should be together)
1 2 3 4
/ x x x
x / x x
x x / x where x = not supplied
/ = supplied a value
(and so the list continues)
Can anybody assist me or give me insights on how to go about this complicated WHERE construct without listing all the probable combinations of the supplied parameters in series of IF statements.
thank you

Hello all,
I have a winform application, where in we get the parameters from the reporting service and we display them in a panel for user's to input their criteria. So far everything worked good, but now we have a requirement wherein dynamic functionality is needed.
For Example:
Based on a selection of a combobox value, we want the other control to be enabled or disabled. Also we want default value of a control to be calculated based on another control's value like .. if user enters value "1" in textbox1 then texbox 2 should have default value of "6". (Textbox1 + 5).........and mix and match of such capabilities.
The Question is........IS IT POSSIBLE??? and if yes...HOW!!!

Hi I am using sql server reporting services 2000 and in a report I have more than 20 parameters of data type Boolean. I want another parameter drop down which have "select all" and "clear all" options. When user select €œselect all€? option from the parameter list all 20 parameters value should be false.
I will be very thankful.

Logically speaking, the two cases below should behave the same. However case 2's output is wrong. Perhaps someone knows what's wrong in case 2.
Case 1:
-------------
AdomdCommand cmd = new AdomdCommand();
conn.Open();
cmd.Connection = conn;
cmd.CommandText = "SELECT Cluster(), PredictCaseLikelihood()" +
" FROM [Data Validation]" +
" NATURAL PREDICTION JOIN" +
" (SELECT " +
" (SELECT @var0 as [var] " +
" UNION SELECT @var1 as [var] " +
" UNION SELECT @var2 as [var]) AS [vartable]) AS t";
Case 2
-------------
AdomdCommand cmd = new AdomdCommand();
conn.Open();
cmd.Connection = conn;
cmd.CommandText = "SELECT Cluster(), PredictCaseLikelihood()" +
" FROM [Data Validation]" +
" NATURAL PREDICTION JOIN" +
" (SELECT " +
" (SELECT @var0 as [var] ";
for(int i=1; i<3; i++)
{
cmd.CommandText = cmd.CommandText +
"UNION SELECT @var" + i.ToString() + " as [var] ";
}
cmd.CommandText = cmd.CommandText + ") AS [vartable]) AS t";

I have three types of specific reports that i have to create with the input parameters (range) either
1: By date (rdl 1)
2.By Month (rdl 2)
3.By Year (rdl 3)
Is it possible ( or how do I ) to create just one report template ( one rdl) with the three sets of parameters ( hiding/invisible which ever two sets base on user selection) and the output of the report will display the desired type( either by year, month or date).
I ask this because its possible to create a drill down report from year down to date etc in report designer (vs 2005). Not sure if I can create one instead of three rdls and with the 'logic' built within that template.
Thanks

Hi,
I have created a report with the report server project template.
the report is created from stoked procedure having defaut input parameters.
With visual studio, i publish my report on reportserver. whenever i access to my report on this url :
http://localhost/ReportServer/Pages/ReportViewer.aspx?%2fReport+Project4%2fReport4&rs:Command=Render. the created report is with the default parameters.
I would like to know if i can transmet parameters for the stocked procedure to build the report with the request i want.
I tried to put parameter directly in the url in this way
http://localhost/ReportServer/Pages/ReportViewer.aspx?%2fReport+Project4%2fReport4&rs:Command=Render&@region='toto'
but without success.
my error message is that one
An attempt was made to set a report parameter '@region' that is not defined in this report. (rsUnknownReportParameter)
My stocked procedure is :
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go
ALTER procedure [dbo].[akli] @region varchar ='m'
as
select * from dbo.Report2 where region=@region
The request used to buid the report ?
DECLARE @region varchar
EXECUTE dbo.akli @region
What is wrong in that ?
Thanks for your help.

Here is a situation in my company:
We have an Office SharePoint 2007 site, we developed a couple of web parts and added them to our site. We used SQL Server Reporting services 2005 as our reporting solution. The reports are hosted on the report center and when we need a report, we open it by sending a URL requesting the report, passing the report parameters in the URL query string. So the report is filtered based on the parameters passed from the web parts.
But since best practices say that you should host reports directly under SharePoint, by configuring the reporting services to run in the SharePoint integrated mode. We followed the steps and installed SharePointRS and we finally succeeded to publish the reports to a SharePoint folder, but we had a limitation: we are unable to pass the report parameters internally to the report hosted in SharePoint. If we passed them in the query string as the report center case, SharePoint neglects them totally.
So the question is: how can I pass parameters internally between a SharePoint web part and a SQL server 2005 reporting services report hosted in SharePoint?

I am trying to develop a report from cube,and it has one drill through report.when i click on sales amount field on main report,then it open the drill through report with details.Here i passed the **(category,subcat,product)parameters(Cascaded)** to drill through report in action part of main report.In my main report i have two columns .
columns are **Level**  and        **Salesamount**. Â
Values are like Â
**[-]category** Â Â Â Â Â Â Â **100**
  **[-]subcat**       **50**
     **product**      **30**
when i click on 100, parameters are passed & it open the detail report correctly, but when i click on 50,the values for subcat parameter is not getting values in detail report and same as the product also.
Here i used the expressions in parameter values
**pCategory**----iif(inscope(category),!fields.category.value,split(join(Parameters!category.value,","),","))
**psubcat**----iif(inscope(subcat),!fields.subcat.value,split(join(Parameters!subcat.value,","),","))
**pproduct**----iif(inscope(product),!fields.product.value,split(join(Parameters!product.value,","),","))

I have a stored procedure that uses a dynamic order by statement. This statement works okay until I try to select ticket's by userEmail which is passed in to my stored procedure as a parameter. Here is the code that works for my dynamic sort order:
CREATE PROCEDURE [dbo].[SelectAllTickets]
@SortOrder varchar(250)
AS
SET NOCOUNT ON
Exec('SELECT a.TicketID, a.TicketDate, a.TicketName, a.TicketDescription, a.statusID, a.resolutionID, a.userID,
b.typeID, b.typeName,
c.userID, c.UserFirstName,
f.statusID, f.statusName
FROM Tickets a
LEFT OUTER JOIN Type b ON b.typeID = a.typeID
LEFT OUTER JOIN Users c ON c.userID = a.userID
LEFT OUTER JOIN Status f ON f.statusID = a.statusID
ORDER BY ' + @SortOrder)
I modied this procedure to create one in which I select tickets based on the userEmail as a criteria as well.. this one fails due to Incorrect syntax near the keyword 'BY'
CREATE PROCEDURE [dbo].[SelectTicketByUser]@SortOrder varchar(250),@userEmail varchar(50)
AS SET NOCOUNT ON Exec('SELECT a.TicketID, a.TicketDate, a.TicketName, a.TicketDescription, a.statusID, a.resolutionID, a.userID, b.typeID, b.typeName, c.userID, c.UserFirstName, c.userEmail, f.statusID, f.statusName FROM Tickets a LEFT OUTER JOIN Type b ON b.typeID = a.typeID LEFT OUTER JOIN Users c ON c.userID = a.userID LEFT OUTER JOIN Status f ON f.statusID = a.statusID WHERE a.statusID <> 40 AND c.userEmail = ' + @userEmail + 'ORDER BY ' + @SortOrder)
Any ideas on what syntax I should be using? Thanks!

Is anybody here knowing how to create a dynamic query based on a multi-value parameter?
e.g. there is a multi-value report parameter called names. For a static query, the where clause of a select statement likes the following
select * from students where name=@names
For the dynamic one, I tried something like the below, but it did not work.
="select * from students where name=(" & Join(Parameters!names ,',') & ")"
Any suggestion would be great appreciated.

The dynamic SQL statements with output parameters, unfortunately, in the documentation are not described.
À) Simple example of the dynamic SQL statement with output parameters
-- dynamic SQL statements expects parameter of type 'ntext/nchar/nvarchar'.
declare @SQLString nvarchar(4000), @ParmDefinition nvarchar(4000)
-- the third parameter passed in the dynamic statement as by output, returns the length of
-- the hypotenuses of a right triangle, two first parameters are lengths of legs of a triangle
declare @nHypotenuse float
select @SQLString = 'select @nHypotenuse = sqrt(square(@nLeg1_of_a_triangle)+square(@nLeg2_of_a_triangle))',
@ParmDefinition = '@nLeg1_of_a_triangle float, @nLeg2_of_a_triangle float, @nHypotenuse float out'
-- we call the dynamic statement in such a way
exec sp_executesql @SQLString, @ParmDefinition, @nLeg1_of_a_triangle = 3.0, @nLeg2_of_a_triangle = 4.0, @nHypotenuse = @nHypotenuse out
-- or in such a way
exec sp_executesql @SQLString, @ParmDefinition, 3.0, 4.0, @nHypotenuse out
select @nHypotenuse -- Displays 5.0
B) Example of usage of the dynamic statement with output parameter and the function GETALLWORDS.
The following stored procedure get all words from a field of the type text or ntext, the word length should not exceed 4000 characters.
CREATE PROCEDURE SP_GETALLWORDSFROMTEXT
@TableName sysname, @FieldIdName sysname, @FieldIdValue sql_variant, @FieldTextName sysname, @cDelimiters nvarchar(256) = NULL
AS
-- this Stored procedure inserts the words from a text field into the table.
-- WORDNUM int – Sequence number of a word
-- WORD nvarchar(4000) – the word
-- STARTOFWORD int – position in the text field, with which the word starts
-- LENGTHOFWORD smallint – length of the word
-- Parameters
-- @TableName name of the table with the text or ntext field
-- @FieldIdName name of Id field
-- @FieldIdValue value of Id field
-- @FieldTextName name of field text or ntext
-- @cDelimiters Specifies one or more optional characters used to separate words in the text field
begin
set nocount on
declare @k int, @wordcount int, @nBegSubString int, @nEndSubString int, @nEndString int, @divisor tinyint, @flag bit, @RetTable bit,
@cString nvarchar(4000), @TypeField varchar(13), @SQLString nvarchar(4000), @ParmDefinition nvarchar(500), @nBegSubString1 smallint, @nEndSubString1 smallint
select @TableName = object_name(object_id(lower(ltrim(rtrim(@TableName))))), @FieldIdName = lower(ltrim(rtrim(@FieldIdName))), @FieldTextName = lower(ltrim(rtrim(@FieldTextName))),
@cDelimiters = isnull(@cDelimiters, nchar(32)+nchar(9)+nchar(10)+nchar(13)), -- if no break string is specified, the function uses spaces, tabs, carriage return and line feed to delimit words.
@nBegSubString = 1, @nEndSubString = 4000, @flag = 0, @RetTable = 0, @wordcount = 0
-- If the temporary table is not created in the calling procedure, we create the temporary table
if object_id( 'tempdb..#GETALLWORDSFROMTEXT') is null
begin
create table #GETALLWORDSFROMTEXT (WORDNUM int, WORD nvarchar(4000), STARTOFWORD int, LENGTHOFWORD smallint)
select @RetTable = 1
end
-- we use the dynamic SQL statement to receive the exact name of text field
-- as we can write names of fields by a call of the given stored procedure in the arbitrary register
-- in the string of parameters definition @ParmDefinition we use a keyword output
-- and by a call of the dynamic SQL statement exec sp_executesql @SQLString, @ParmDefinition, @FieldTextName = @FieldTextName output

-- GETALLWORDS() User-Defined Function Inserts the words from a string into the table.
-- GETALLWORDS(@cString[, @cDelimiters])
-- Parameters
-- @cString nvarchar(4000) - Specifies the string whose words will be inserted into the table @GETALLWORDS.
-- @cDelimiters nvarchar(256) - Optional. Specifies one or more optional characters used to separate words in @cString.
-- The default delimiters are space, tab, carriage return, and line feed. Note that GETALLWORDS( ) uses each of the characters in @cDelimiters as individual delimiters, not the entire string as a single delimiter.
-- Return Value table
-- Remarks GETALLWORDS() by default assumes that words are delimited by spaces or tabs. If you specify another character as delimiter, this function ignores spaces and tabs and uses only the specified character.
-- Example
-- declare @cString nvarchar(4000)
-- set @cString = 'The default delimiters are space, tab, carriage return, and line feed. If you specify another character as delimiter, this function ignores spaces and tabs and uses only the specified character.'
-- select * from dbo.GETALLWORDS(@cString, default)
-- select * from dbo.GETALLWORDS(@cString, ' ,.')

Hi All,
I Hope someone can help me out with this problem.. its pretty NB.
I have a pair of multivalued parameters. So, parent and child... the child needs to get its selection based on the selection made by the user on the parent parameter ( the child parameter is hidden).
Fictional values:
Parent Parameter: SelectAll, ALL , 1 , 2
Child Parameter: Home, Work, Play
If user selects "ALL" from the parent parameter I need Home and Play selected.
My idea was this:
=iif(Parameters!Parent.Value(1) = "All","Home,Play") <-- in Available values.
However, the dataset that reads this value does not like the coma delimited string.
This dataset is a cube created dataset, reading the child parameter.
Any help is greatly appreciated.
Kind Regards,
Neil

Is it possible to dynamically refresh the report model of the report builder?
could it even be using code with any of the interfaces?
When we add a table or add a column to the table in database , will the report model get refreshed automatically or do we need to do it externally. If so, can we use any of the objects and write a custom code in VB.

Good morning, all
I have a really cool Budget report which has two matrices on it. One is used/visible if the user selects four levels of grouping, and one is used if the user selects only three levels of grouping. The four choices for grouping are four fields, Par, FERC, Point, and Resource.
Since grouping is optional, I need a way to pass the parameter for a field that is not grouped on from the main report to the drillthrough report. For example if the user chooses to group on all fields but Point, I need to pass the report parameter that was used by the main report for Point to the drillthrough report as a report parameter.
So, I tried testing the three grouping levels values and if none were equal to "Point" then pass in the parameter by putting the following expression in the Parameter Value box for the Point parameter on the Navigation tab of the datacell of the main report that is the drillthrough link:
=iif(
Parameters!GroupLevel1.Value <> "Point"
and
Parameters!GroupLevel2.Value<>"Point"
and
Parameters!GroupLevel3.Value<>"Point"
,
Join(Parameters!PNTPoint.Value,",")
,
Fields!Point.UniqueName
)
But this is not working; the drillthrough report shows a blank dropdown for the Point parameter and I have to manually set it. Does anyone see an error in the syntax of the iif statement?
Any references, links, resources or good clean jokes would be greatly appreciated.
Thanks,
Kathryn
