Multi-Step Transaction, fails but reports success

I have for example the following SQL:
BEGIN TRAN
Delete from users where userid = 102
Update mainSettings set userCnt = UserCnt -1
COMMIT TRAN
If for example the "update" statement fails, but the "delete" statement
is successful - the overall transaction reports no error, and thus, my
appliction thinks everything was a success.
Any ideas?

the db. Also, you have to check the return value of the sp.

rollback transaction
raiserror('Error updating from table [mainSettings].', 16, 1)
return 1
end
COMMIT TRAN
return @.@.error
go
declare @.rv int
declare @.error int
declare @.tc int
set @.tc = @.@.trancount
exec @.rv = proc1 102
set @.error = coalesce(nullif(@.rv, 0), @.@.error)
if @.error != 0
begin
print 'there was an error.'
end
if @.@.trancount != @.tc
rollback transaction

programmers can not make the decision for you as to whether or not the error
is sufficient to roll back the transaction. That is for you to decide, so
you much catch the errors and rollback the transaction when necessary.. (
There are types of errors which will automatically roll back the transaction
without your intervention. These are generally more severe errors which
cause batch abort, or you have been chosen as a deadlock victim.)

Multiple selects on PArameter drop down

I have a parameter dropdown as USERID.

I want a functionality that the user can selct multiple userid's to show more than one record as output for comparison purpose.

How can i achieve this multiple select (i.e cntrl+click) within parameter dropdown.

Thanks,

Kiran.

In the report parameters window, check the 'Multi-value' box on your UserID parameter. In the available values section, you can type the possible values, or query the database to get the list.

You will also need to take the multiple values into account on your data query, you'll need to use 'IN' instead of '=' on your where clause for UserID.

This will show on the report as a drop down, where the user can check which values to run the report with.

Hope this helps,

Jarret

Thank you Jarret.

I cannot find teh checkbox for 'multi-value'' allowed . I am using reporting services 2000 on visual Studios.NET 2003 SQL Server 2000.

Is this an issue for me only. I have the checkboxes for allow null values and allow blank values for the userid parameter.

thanks.

Sorry, I had assumed that you were running RS 2005. In Reporting Services 2000, a report parameter can only be defined to allow the user to enter a single value.

Thanks Jarret,

Is there a wor around that I should be trying.

Appreciate the time.

Hmmm...

You could try changing the parameter type to string and make your data query use 'IN', then have the user type a comma delimited list. I haven't tried it, but you might be able to get it to work.

This did not work for me. I shifted to 2005 and implemented it.
