Passing Parameter Into Dataset

Jun 15, 2007

Hello



Im trying to pass a integer parameter to my dataset query depending on the selection made from the user. It is suppose to get the Top number off records based on what number the user chooses



I get the error Incorrect syntax near '@Param_TopNo, If i take the top @param_topno out the query works



The cutdown version off the query is...



Select Top @Param_TopNo SaleDate, Consultant, Productname

From tblSales

where product = 2000


Im not sure if the method above is even achievable !!!! does anyone know how i can pass a variable/parameter into my dataset and maybe provide an example off the code.



thanks

Reporting Services :: Passing All Parameter Selection To Dataset Query

Nov 20, 2015

I have a report that prompts the user to select a parameter, for simplicity, let's say the parameter is for color choice, options are Red, Yellow, Blue or *. The * is for include all colors. I am passing that parameter back to the dataset query which, again for simplicity is

select
Hue from AvailableColors
whereColor
= @ColorParam.

For a specific color this works fine, for the "*" selection it returns a null. It would seem that I need to convert the * to % but I am not sure how.....

Reporting Services :: Adding Dataset Parameter Doesn't Add Report Parameter In Visual Studio 2008 SSRS

Apr 22, 2015

I'll go to a dataset, open up the query designer, add a new parameter, then refresh the fields, but the parameter won't be added as a report parameter.  If I go to the dataset properties under the list of parameters, the value in the dropdown will be blank.  However, sometimes this will automatically add. 

Is this a bug in Visual Studio?  How do I get around this?

Reporting Services :: Multi-value Parameter Not Passing In Subreport Parameter List

Jul 29, 2015

I have two report , first is main report which is matrix and have one parameter User_ids which is multi value selection and my second report is basic chart of user_wise performance.

Now, my main report (matrix ) works fine for Multiple selection of users and i have putted one textbox on main report chart which has action properties set for chart report, when user click on chart button it must goes to chart with user selected in main report. Now , i have used expression for parameter to send it like ..

=join(parameter!user_id!value,",") which pass selected value to chart 

And when I am selecting single user it passing that value to chart parameter list but , when it is more than one user it errors with conversion failed when converting the nvarchar value '121,128' to data type int. But my chart also works when passing 121,128 in user parameter in preview of report .

Reporting Services :: Passing Parameter Via URL Using Javascript - Missing Parameter Value

Dec 3, 2015

Using SQL Server 2008R2 and Report Builder 3.0..I have an action set in a text box of a table. My intent is to pass the value of that text box (which is variable) to a sub-report in a popup window. Here's my code: URL....The parameter of the report I'm trying to open is @SONum.I'm guessing my error is involved in the formatting of how the value of the parameter is being passed. I've also seen examples where the report server and report values were parameterized, but I don't know where to define

Parameters!ServerAddress.Value anywhere.Do I need to have something set up a certain way within the report I'm opening? Here's the report Parameter settings on the report I'm trying to open.

Filters For Dataset From Parameter - How To Ignore If The Parameter Is NULL ?

Apr 10, 2007

Hi,

I am starting to use reporting services and I created a report that takes 4 parameters for a Filter on the dataset.

The idea is the create snapshot nightly and then display the report filtered based on parameters to users.



I'd like that the filter be ignored for a parameter if the parameter is passed as NULL,

Right now I defined it this way :



Left =Fields!RegionCode.Value
Operator =
Right =IIF(IsNothing(Parameters!RegionCode.Value),Fields!RegionCode.Value,Parameters!RegionCode.Value)

I do this for the 4 parameters that are passed, if they are null, make then equals to the field.

I was wondering if there is a way to ignore the whole parameter all together, I would guess it'll be faster to execute.



Thanks

Passing A Dataset To Reporting Services

Feb 2, 2007

I've seen questions similar to this posted, but I'm unable to find a clear answer to what I need to do.

We are currently using Crystal Reports, generating a dataset in our application and passing it to Crystal. Due to the many problems we have with Crystal we are now looking to move to Reporting Services 2005, but I can't find out how to pass it a dataset.

Although we do use SQL Server for data storage, we have many reports with calculations that are way too complicated to use calculated fields, and which change too often to want to store them in the database. One solution might be to store the data temporarily and regenerate it each time it's required, but this doesn't seem very elegant. So please could someone tell me if there is a way to do what I'm after and point me at a page that gives a nice clear explanation.

Thank you

Passing DataSet To MS Access Report

May 28, 2007

I have many MS Access reports that process recordsets obtained from a MySQL database, based on a user-selected date range. This uses VBA and input boxes. I'm now creating .aspx pages to get the user input via the web, and am successful in creating a DataSet. My .aspx.vb code includes using Automation to open the Access report in Snapshot Viewer (DoCmd.OutputTo). How do I pass the DataSet to MS Access to replace using recordsets?



My VBA code in Access used to be this:




Code Snippet

Dim ws As Workspace
Dim strConnection As String
Dim dbs As Database

Dim rst_chg As Recordset

Set ws = DBEngine.Workspaces(0)
strConnection = "ODBC;DSN=xxx;DATABASE=xxx;" _
& "SERVER=10.1.144.xxx;" _

& "UID=xxx;PWD=xxx;PORT=xxx;OPTION=0;" _

& "STMT=set wait_timeout=100000;;"




Set dbs = ws.OpenDatabase("", True, True, strConnection)

Set rst_chg = dbs.OpenRecordset("SELECT ...")

'process the recordset ...




I'm thinking I should be able to eliminate most of this code and Set rst_chg = DataSet. I've been successful with using WriteXml in the .aspx.vb page and Application.ImportXML in my VBA to pass the data using XML, but this writes to the hard drive, and also creates a database in Access (overhead I would rather not have to deal with). Again, is there a way to open the DataSet directly in my VBA code?



Thanks,

Guy Rivers

Passing NULL To DataSet Parmameter

Apr 13, 2007

Hey All,

I have a number Stored Procs that have been around for a while that pull the entire list, or if I pass an ID, will just the record for that ID like below.

I want to be able to use these querries to poplate Multi-Select parameter dropdowns. going to the Data tab and creating a new dataset, I put in the SP name, and close the window. I then go to the Red ! point to preview the data it prompts me for my ID parmaeter on my SP. In the dropdown list it has '<Null>' (no ' though). When I run it, it works fine and returns all of my records.

When I run the report, it errors saying I didn't pass a parm for ID. I go back to the data tab, and edit my DataSet hitting the elipse. I go to the 3 tab called parameters, and type the following I get the following errors:



@ID = <Null> ---- ERROR - [BC30201] Expression expected

@ID= ---- ERROR - Return statement in function must return a value

@ID = Null -----ERROR - Null constant not supported use System.DBNull instead

@ID = System.DBNull ----ERROR - [BCS30691] DBNull is a type in System and cannot be used in an expression

@ID=System.DBNull.Value --- NO ERROR, but it does not return anything either. I also did a SQL Trace, and I can see that it doesn't even send the querry to the database.



Does anyone know another magic value I can pass to get this to work?



I am being a little stuborn, I know that I could just create new procs, and wrap up the null, but the more stuff you create the more you have to maintain, so I would prefer to reuse these.



Thanks in advance.



Eric Wild



PS: My company is moving from crystal reports to Reporting service, and Reporting services is Rocks! It is very intuitve, simple and straign forward. The formatting is easy with the table and the matrix control blows away the crosstab control in crystal. Also, I'm finding that because crystal was so un extendable, that I would spend hours shaping sql to get over it's blemishes, and hours shaping it in the report, only to sometimes reliaze that the proposed onetime hack wouldn't work, and have to start all over! So far with RSS any tips and tricks I have learned can very easily be applied to any report I work on! Aslo, I do mostly interanet web apps, and it is nice to dump my reports on the Report Server, and not worry about haing to create a web page, create a datasource and all the ansilary stuff to go along with it. The only thing I don't like is the name 'Roporting Services': It does not stick out too far in Google Searches like 'AJAX.NET' or 'ASP.NET'. Anyway kudoes to the Reporting Services team!

Reporting Services :: Passing Parameters To MDX Dataset

Oct 1, 2015

I have an MDX data-set query as follows: -

Member [Measures].[Measure3] As [Measures].[Value Rent Period Receipts]
Member [Measures].[Measure4] As (([Measures].[Value Rent Period Receipts]*-1)/[Measures].[Value Rent Period Debit])

Select {[Measures].[Measure1]
,[Measures].[Measure2]
,[Measures].[Measure3]

[Code] ....

There are two parameters; the value of lag passed to the LastPeriods function, and tenancy types passed in the where clause

I have a third parameter I would like to use called FirstDate and this I would like to pass to the LastPeriods function as the second argument

FirstDate is a value from my Time dimension, something like [Time].[Fiscal Time].[Sep. 15]

When editing the query to: -

Member [Measures].[Measure3] As [Measures].[Value Rent Period Receipts]
Member [Measures].[Measure4] As (([Measures].[Value Rent Period Receipts]*-1)/[Measures].[Value Rent Period Debit])
Select {[Measures].[Measure1]
,[Measures].[Measure2]

[Code] ....

The code errors. I have tried all sorts of formats such as  LastPeriods(@LagMonths,[@FirstDate]) and LastPeriods(@LagMonths,[Time].[Fiscal Time].[@FirstDate]), but nothing works

Basic Parameter In Two Dataset

Feb 11, 2008


Hi All

I have two datasets (for querying active directory but this is kind of irrelevant for my problem which is a basic one)

The first gets a list of groups and I want to display GroupName in a dropdown list:

SELECT DistinguishedName, GroupName, GroupDescription
FROM tvf_GetListOfGroups('LDAP://OU=Applications,OU=Groups,OU=Production,DC=MRP,DC=NET,DC=NZ','Subtree')
ORDER BY GroupName


The above is fine and works but then I want to use the corresponding DistinguishedName of the GroupName selected in
the dropdown to drive the second query to populate the report


SELECT * FROM tvf_GetGroupMembers('LDAP://' + @DistinguishedName)
ORDER BY UserLogin

My problem is how to populate @DistinguishedName with the correct value to run run the query.

How? Please?

Thanks

Passing Parameter To SP Using IN

Jan 18, 2002

Hi,

I have a stored proc as follows:

Create stored procedure sp_test
@Cno nvarchar (1000) AS
SELECT * FROM Contracts WHERE Cno IN (@Cno)

How do I actually pass the parameters to the stored proc?

sp_test "'cn01','cn02','cn03','cn04'" doesn't work.

In VB.NET this doesn't work either:
dim s as string = "'cn01','cn02','cn03','cn04'"
cmd.parameters.add(new sqlparameter("@Cno",nvarchar,1000))
cmd.parameters("@Cno").value = s


I don't want to parse the string inside the proc and then Exec the parsed string.

TIA

Passing A Parameter Value

Apr 9, 2008

Hi ,

I have this situation,I need to store results of a Select Count(*) from TableA to a parameter and only if the value of the count(*) is greater than 50,000,a notification mail would be sent out to the table owner.Currently this is what I have done:
1) Use SQL task to include "Select Count(*) from TableA"
2) In parameter mapping tab of SQL Task, define the following
Parameter name : Table::Count
Direction: Input
Data Type: Numeric
Parameter Name : @Count
3) I have connected the SQL Task to a Send Mail Task [ Only If @count>50 000, then a mail should be sent out]
4) The constraints has been set as
Evaluation Operation : Expression and Constraints
Value: Success
Expression : @Count >"50000"

In SSIS tab > Variable
I have set the following
Variable Name : Count
DataType : Int32

Can someone advise me where I am going wrong, as when I execute the SQL Task turns greens and ends.Even when the count of tableA is greater than 50 000, no mails I sent out[send mail task does not get executed]

Thank You in Advance

Parameter For Where In (@Par1) In Typed Dataset

Aug 21, 2007

Hi,
 Is there any work around to passing a set of strings to a parameter in a Typed Dataset for example I am pasing '4226222172004','4212012182004' which I build on my code the number of items will vary passed on the user selection but since the Typed Dataset uses sp_executesql and the parameters are change to '''4226222172004'',''4212012182004'''
 Any ideas how I can format the Parameter I am passing.so that it will end like where in ( '4226222172004','4212012182004') instead of where in ('''4226222172004'',''4212012182004''') I again the number of parameters will very.

How Do I Use A Parameter In A Dataset Field Value Using An MDX Query?

May 23, 2007

Let me simplify. The value of my dataset field Dimension_1 is



[SOB Year].[Yr Id].[Yr Id].[MEMBER_CAPTION]



I want to use parameters for SOB Year and Yr Id like I do on the query.



But if I use



="["& Parameters!dimension_1_table.Value &"].["& Parameters!dimension_1_column.Value &"].[" & ["& Parameters!dimension_1_column.Value &"]"



it returns null for the values. I don't know how to make these parameters





I am passing in parameters for the table and column to build an MDX query here is my query.



="SELECT NON EMPTY { [Measures].[Liability Amt] } ON COLUMNS, NON EMPTY { (["& Parameters!dimension_1_table.Value &"].["& Parameters!dimension_1_column.Value &"].["& Parameters!dimension_1_column.Value &"].ALLMEMBERS ) } DIMENSION PROPERTIES MEMBER_CAPTION, MEMBER_UNIQUE_NAME ON ROWS FROM [SOB Clean] CELL PROPERTIES VALUE, BACK_COLOR, FORE_COLOR, FORMATTED_VALUE, FORMAT_STRING, FONT_NAME, FONT_SIZE, FONT_FLAGS"





Anyone know what value I need to use on the dataset field to access the column?



Thanks,

Parameter Cannot Set The Command Text For Dataset

May 14, 2007

Hello



I get the following error in a very quick test system i created:



An error occurred during local report processing.

An error has occurred during report processing.

Cannot set the command text for data set 'test'.

Error during processing of the CommandText expression of dataset 'test'.



My sql is:

= "select T.testid, T.test from test T " & Iif(Parameters!test1.Value = 1, "", "Where T.testid = " & Parameters!test1.Value)



There is nothing obviously wrong in the code as far as i can see



The parameter 'test1' is of type 'string'



The database 'test' has 2 columns of type 'smallint' and 'Name:nvarchar(50)'



I am at a loss, as this query is really simple, and is similar to the example query set up my microsoft which works fine

How Can I Set Default Value Of Parameter That Come From Dataset By Using Expression?

Feb 27, 2008

Hi,

Now I can query dataset and bind to report parameter. But I have some problem about setting default value. I don't know, how to select max value from dataset by using expression.

Example, I query disticnt year from my table. The result has 2 years "2007" and "2008"
select distinct year(mytime) as myyear from mytable.

I set available parameter by using this dataset. Then, I set default value for this parameter by the other dataset ...

select max (distinct year(mytime)) as maxyear from mytable.

I want to select max value by using expression, not select max by using dataset.

How can I do?

Thank you very much.

Aspx Vb Sql Parameter Passing

Aug 9, 2004

Hello,
Can someone kindly point out what is wrong with the following code file. I'm trying to:
- fill a dropdown from a db on page load (this works!)
- when user selects from the list and hits a button, pass the dropdown value to a second query
- use the second query to make another call to the db and fill a data grid

In the code below, if I swap an actual value (eg '1005') into the command and comment out the .Parameter.Add statements, the dategrid is filled sucessfully. Otherwise, when the button is pressed, nothing is displayed.

Thanks

PS comments about my coding approach are welcome - I'm new to aspx...

Interesting problem, selecting and updating (with reference to a Form View) works great. Whenever I try to delete I get this error:Must declare the variable '@template_id'.



Description: An
unhandled exception occurred during the execution of the current web
request. Please review the stack trace for more information about the
error and where it originated in the code.

Exception Details: System.Data.SqlClient.SqlException: Must declare the variable '@template_id'.
Here is my code:<asp:SqlDataSource ID="SqlTemplateDS" runat="server"SelectCommand="SELECT [template_id], [client_id], [language], [label], [email_default], [email_template], [event_template] FROM [CMT] ORDER BY [template_id]"DeleteCommand="DELETE FROM CMT WHERE (template_id = @template_id)" ConnectionString="<%$ ConnectionStrings:BrandMSConnectionString %>">                                   </asp:SqlDataSource><asp:GridView ID="grdTemplates" runat="server" AutoGenerateColumns="False"                                             DataKeyNames="template_id"                                            DataSourceID="SqlTemplateDS"                                             Font-Names="Verdana"                                             Font-Size="Small"                                             ForeColor="Black"                                             Width="100%"                                             OnSelectedIndexChanged="grdTemplates_SelectedIndexChanged"                                             CellPadding="2">    <Columns>    <asp:BoundField DataField="template_id" HeaderText="ID" ReadOnly="True" SortExpression="template_id" /><asp:BoundField DataField="client_id" HeaderText="Client" SortExpression="client_id" /><asp:BoundField DataField="language" HeaderText="Language" SortExpression="language" /><asp:BoundField DataField="label" HeaderText="Label" SortExpression="label" /><asp:CheckBoxField DataField="email_default" HeaderText="Default" SortExpression="email_default" /><asp:CheckBoxField DataField="email_template" HeaderText="Email" SortExpression="email_template" /><asp:CheckBoxField DataField="event_template" HeaderText="Event" SortExpression="event_template" /> <asp:TemplateField HeaderText="Options"><ItemTemplate> <asp:LinkButton ID="btnModify" CommandName="Select" runat="server" ForeColor="Blue">Edit</asp:LinkButton> | <asp:LinkButton ID="btnDelete" CommandName="Delete" runat="server" ForeColor="Blue">Delete</asp:LinkButton></ItemTemplate></asp:TemplateField> </Columns><HeaderStyle BackColor="Khaki" /><AlternatingRowStyle BackColor="Beige" /></asp:GridView>Any ideas?Chris
