Hi all,
From the "How to Call a Parameterized Stored Procedure by Using ADO.NET and Visual Basic.NET" in http://support.microsft.com/kb/308049, I copied the following code to a project "pubsTestProc1.vb" of my VB 2005 Express Windows Application:
Imports System.Data
Imports System.Data.SqlClient
Imports System.Data.SqlDbType
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim PubsConn As SqlConnection = New SqlConnection("Data Source=.SQLEXPRESS;integrated security=sspi;" & "initial Catalog=pubs;")
Dim testCMD As SqlCommand = New SqlCommand("TestProcedure", PubsConn)
testCMD.CommandType = CommandType.StoredProcedure
Dim RetValue As SqlParameter = testCMD.Parameters.Add("RetValue", SqlDbType.Int)
RetValue.Direction = ParameterDirection.ReturnValue
Dim auIDIN As SqlParameter = testCMD.Parameters.Add("@au_idIN", SqlDbType.VarChar, 11)
auIDIN.Direction = ParameterDirection.Input
Dim NumTitles As SqlParameter = testCMD.Parameters.Add("@numtitlesout", SqlDbType.Int)
NumTitles.Direction = ParameterDirection.Output
auIDIN.Value = "213-46-8915"
PubsConn.Open()
Dim myReader As SqlDataReader = testCMD.ExecuteReader()
Console.WriteLine("Book Titles for this Author:")
Do While myReader.Read
Console.WriteLine("{0}", myReader.GetString(2))
Loop
myReader.Close()
Console.WriteLine("Return Value: " & (RetValue.Value))
Console.WriteLine("Number of Records: " & (NumTitles.Value))
End Sub
End Class
//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
The original article uses the code statements in pink for the Console Applcation of VB.NET. I do not know how to print out the output of ("Book Titles for this Author:"), ("{0}", myReader.GetString(2)), ("Return Value: " & (RetValue.Value)) and ("Number of Records: " & (NumTitles.Value)) in the Windows Application Form1 of my VB 2005 Express. Please help and advise.
Thanks in advance,

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.

Hi,
I have an app in C# that executes a query using SQLCommand and parameters and is taking too much time to execute.
I open a SQLProfiler and this is what I have :
exec sp_executesql N' SELECT TranDateTime ... WHERE CustomerId = @CustomerId',
N'@CustomerId nvarchar(4000)', @CustomerId = N'11111
I ran the same query directly from Query Analyzer and take the same amount of time to execute (about 8 seconds)
I decided to take the parameters out and concatenate the value and it takes less than 2 second to execute.
Here it comes the first question...
Why does using parameters takes way too much time more than not using parameters?
Then, I decided to move the query to a Stored Procedure and it executes in a snap too.
The only problem I have using a SP is that the query can receive more than 1 parameter and up to 5 parameters, which is easy to build in the application but not in the SP
I usually do it something like
(@CustomerId is null or CustomerId = @CustomerId) but it generate a table scan and with a table with a few mills of records is not a good idea to have such scan.
Is there a way to handle "dynamic parameters" in a efficient way???

Hello:
I just recently bumped into this problem and I think I know what's causing it. This is the setup:
Report Parameters: FromDate, ToDate, DivisionalOffice, Manager, SalesRep
dsCalendarEvents Parameters: FromDate.Value, ToDate.Value, DivisionalOffice.Value,
dsDivisions Parameters: N/A
dsManager Parameters: DivisionalOffice.Value
dsSalesRep: DivisionalOffice.Label
When I query the ReportServices WS and scan the parameter dependencies for SalesRep it says there are four dependencies: FromDate, ToDate, DivisionalOffice and Manager!!!
If I change "dsSalesRep" to use "DivisionalOffice.Value" the ReportingServices WS parameter dependency scan returns only one dependency for "SalesRep" parameter!!!( This is the correct behavior )
Has anybody seen this behavior and more importantly, is there a work around?
Regards,

Hello all,
Given:
string commandText = "Categories_Delete";SqlCommand myCommand = new SqlCommand(commandText, connection);myCommand.CommandType = CommandType.StoredProcedure;
Is there a reason NOT to use myCommand.Parameters.AddWithValue("@CategoryID",CategoryID); I'd prefer to use that over myCommand.Parameters.Add("@CategoryID", SqlDbType.Int, 4).Value = CategoryID; as I have these functions being created dynamically and hope to get away from a big lookup to try to convert System.Types into SqlDbTypes. [shudder]
It seems that ADO.NET makes an implicit conversion to the valid type. If this is correct then I can move on fat dumb and happy. Anyone have any good insight?
Thanks,

Hi,
I'm having a bit of trouble with SQL Parameters. I can't seem to define the type when creating the parameters.
Here's what I've done:
I have a function that processes my request and returns a datatable:
Public Function Grab_Data(querystring asn string, params() as SqlParameter) as DataTable
... dims all the necessary variables
Try
...creates the connection and command
Dim p as SqlParameter
For each p in params
p = command.parameters.add(p)
p.direction = parameterdirection.input
Next
...opens connection, creates dataset and fills it
Finall
....disposes connection and command
End Try
Return datatable
End Function
I call this function by:
...dim the necessary variables
querystring = "SELECT * FROM Tbl_Users WHERE Joined>=@date"
dataTable = Grab_Data(querystring, New SQLParameter("@date", DateTime.Today))
My code works fine and I get the results that I want, but no where in my code is the type of the parameter defined.
I tried calling the function like:
Grab_Data(querystring, New SQLParameter("@date", SQLDBType.DateTime, DateTime.Today))
But when I do this, I get an error saying that no value is assigned to @date.
Can anyone tell me what I need to modify so that I can pass the type of the parameter to the function?
The reason why I am not explicity defining the parameters in the function is because I can reusing the function numerous times throughout my code. So some calls have three parameters passed to it and some and none.
Thanks.

Hi all, I am using classic ASP and SQL Server 2005. Can I use parameters like @whatever in my asp code or are they for stored procedures exclusively? I am trying to change the output of a request.form into a paramater so I can prevent SQL injection I am aware of using trim to counter this but I wasn't sure of the best practice.

I'm trying to do this:
ALTER PROCEDURE dbo.SkillSearch
(
@skillname char(255)
)
AS
SET NOCOUNT ON
SELECT * FROM Skill WHERE SkillName LIKE @skillname
However, when I run dbo.skillsearch 'ph%'
I get an empty set, while dbo.skillsearch 'php' returns the results expected.
I am therefore assuming that I can't use a parameter for a LIKE clause with any wildcards?
Is there any way around this other than manually building the SQL statement in the SP and then executing it? I'd obviously prefer to not have to do it that way for all the SQL Injections and related reasons.
Wouldn't this also kill my query optimization benefits, manually building the statement each time?
Thanks,

I am trying to use the URL to pass a parameter to a report. I have tried several ways to make this happen with no effect. My report is using a sproc that has a int parameter. I have tried make a list of partial parameters and passing the parameter I want through the URL. I hide the prompt. I put NULLs and Blanks allowed. I have created a linked report then hid the prompt. I used parameters=false instruction. Here is the basic URL http://reportsrv/Reports/Pages/Report.aspx?ItemPath=%2fActiveTasks%2fProject+Details&rs:Command=Render&ProjectID=56.

I have a table of 25-30 million properties, from which are retrieved~150 centered on a point, based on the parameters -- coordinates,property type and date of transaction. There's an SP (also implementedas a function returning a table) to return the desired records.This look-up takes the most time in the C# program that calls it, andshould be optimized. It was suggested that instead of having an SP onthe server, each time the program should create an SP that is the same,however without any parameters -- with the values hard-coded. Thenexecute it, and drop it. This way, the execution plan will becustomized for the specific parameters. I tried it and it turns outthe suggested method is noticeably faster, even compared to recompilingan SP every time. I was wondering if there is a way to get equivalentperformance out of an SP or UDF that has parameters, or is thisapproach necessarily going to be less optimized than hard-codednon-parameters.Thanks,Jim

I know that you can amend the URL of a report and set parameters that way but is there a way you can do the reverse? I need users to be able to save reports to their favourites while retaining the currently selected parameters. Therefore I need the URL to display the parameters without the users having to manually type them in. Is there a way of configuring this?

Hi All
Beginner's question:
I have a dataset which provides two columns (Id and Name) and I'm using it to drive a dropdown list (parameter)
I want the user to see the Name but I want the Id to be used as the parameter in the subsequent query that provides data to the report.
How do I manage that?
Thanks

Probably a pretty easy question: How do I implement 2 parameters in a OR situation? I want the users to be able to either choose a value for A OR a value for B, i.e. select the product name OR the product code. I have 3 datasets defined, 1 for each parameter and 1 for the report output. The last one has ...WHERE A=@A or B = @B. When testing, it seems to require both. I want them to be mutually exclusive, the user can only pick one.

Connected to AS/400 server through ODBC. Can submit queries, just built a matrix report, looks good.
However I want to incorporate a Parameter and have tried prefacing the parameter COSTCENTER with everything under the sun:
@COSTCENTER (SQL Server version of parameter declaration)
:COSTCENTER (Oralce version of parameter declaration)
%COSTCENTER
#COSTCENTER
etc. etc.
I keep getting the same error:
Error in WHERE clause near '@'. Unable to parse query text.
My inquiries are as follows:
1. Can you use parameters with an AS/400 connection?
2. If yes, howshould the parameter be declared?
I searched BOL, GOOGLE, so far nothing...

Is it possible to edit the parameter layout generated by reporting services 2005 - i have drop down lists which are too narrow (they do not widen to fit the values so one has to scroll left and right in the drop down list to see whole value).
It automatically wides if it is not a multi value param.

Hi all,
I'm working on a project that builds a report in RS 2005 agains the data cube created in AS 2005.
I created a report in RS 2005 against database table, and the parameters were easy to be added in the T-SQl query.
There are about 15 parameters needs to add in the query, and I can use "IN, =, Betweent.. and ," in the "where" clause, e.g.,
select *
FROM Mytable1
WHERE EmployeeID IN (@EmployeeID)
and EmployeeName] IN (@EmployeeName)
...
and Salary between @SalaryFrom and @SalaryTo
... and Date between @DateStart and @DateEnd
most of the restriction fields are column fileds in the report.
Right now, I need to switch the datasource to the data cube, and then I have to use MDX to do the query. But I really cannot get enough information about MDX in the MSDN library --> SQL Server Language Reference -->MDX Reference to write a MDX query, especially with parameters.
Could somebody tell me how to do it?
please give me a complete example for the following T-SQL query:
select t1.EmployeeName, t2.Salary, t3.Date, t4.SaleAmount
FROM Mytable1 t1, mytable2 t2, mytable3 t3, mytable4 t4
WHERE t1.EmployeeName IN (@EmployeeName)
...
and t2.Salary between @SalaryFrom and @SalaryTo
... and t3.Date between @DateStart and @DateEnd
and t4.SaleAmount betweent @SaleAmountFrom and @SaleAmountTo
in the cube, those data are stored in DimEmployee (field EmployeeName), DimSalary(filed Salary), DimDate, FactSales, and the SaleAmount will be the messure field.
Or if sombody can provide me the link to MDX tutorial other than what I can get from the "MDX reference" I mented above, I'll be very appreciated !!
Thanks!!
