How to simulate an array in SQL Server

Just thought some might be interested in how to identify individual
items in an 'array' by declaring a local variable as table
----
declare @.MyTable table (MyRowID int identity, MyData varchar(255))
declare @.MyCurrentRow as int
declare @.MyRowCount as int
insert into @.MyTable select Name from sysobjects -- (or whatever)
set @.MyRowCount = @.@.RowCount
-- @.@.Rowcount hold the count of the last table in these cases anyway
-- then you can use statement to access the nth. row in the 'array'
select MyData from @.MyTable where MyRowID = 5 -- as an example
--
-- or step through the table using @.MyCurrentRow
Set @.MyCurrentRow = 1
while @.MyCurrentRow < @.MyRowCount +1
Begin
Select MyData from @.MyTable where MyRowID = @.MyCurrentRow
set @.MyCurrentRow = @.MyCurrentRow + 1
Continue
end
Just thought it might help. It isn't rocket science but I saw a few
with problems so thought I'd post.
I needed it to obtain individual values from a table and use those
values to call a stored procedure repeatedly.

How to send parameters to report when executing ReportingService.Render

I'm trying to figure out how you send/set the report variables when using the ReportingService.Render method.

I can get the ReportParameters array using GetReportParameters but can't seem to find a way to populate the ParameterValue array that is passed as a variable in the Render method. I've tried creating an ArrayList comprised of ParameterValue objects (non-array), adding them to the ArrayList, and trying to convert that to a ParameterValue array. The example code I found is in VB.NET and looks like this:

reportParametersArray = rs.GetReportParameters(reportPath, Nothing, True, _
reportParameterValuesArrayList.ToArray(GetType(ParameterValue)), Nothing)

I tried to do the same thing in C#:

rpReportParams = rsReports.GetReportParameters(sReportPath, null, true, arrayListParams.ToArray(System.Type.GetType(ParameterValue)), dscCredentials);

The compile error is :
'ReportService.ParameterValue' denotes a 'class' where a 'variable' was expected

Putting quotes around ParameterValue returns the following error:
Argument '4': cannot convert from 'System.Array' to 'ParameterValue[]'
Anyone had success populating report parameters or have a suggestion?

Thanks,

O.

If arrayListParams is an ArrayList that contains ParameterValue objects, try this in C#

(ParameterValue[])arrayListParams.ToArray(typeof(ParameterValue))
