Indicating the NULL value in Report Expression Syntax

Hi,

I would like to know how I can indicate a NULL value in a report expression in SSRS / Report Designer.

I am trying to code :

IIF(Value_A = 0, <NULL>, Value_A)

It may look weird but I am trying to return NULL values when Value_A is 0 (zero), in the sample scenario above.

I have tried using the keyword "NULL", but it is highlighted as a syntax error, and suggested to use System.DBNull. I tried it and then it says that components of the System collection cannot be used in an expression, so I am left drawing blanks.

Thanks.

regards,
Kenny

Use the VB keyword "Nothing"

=Iif(Fields!Value_A.Value = 0, Nothing, Fields!Value_A.Value)

|||Hi Adam,

Thanks for the tip. Worked like a charm.

Where else can I get a list of VB keywords I can use in Report Designer / SSRS / SQL Server 2005. I have some background with VB6 prior and was hoping I could port a whole bunch of them over to be used here.

Indexing question

Hello All,
Have seen 2 different databases now both on 2005 STD edition different
servers.
That still indicate fragmentation in their indexes (both clustered and non
clustered) immediately post rebuild proccess. I am looking for broad sweeping
statements to stimulate my thought processes as to why this is occuring.
Thanks in advance,
How many pages do they have? If it is less than 8 you will never get rid of
all the fragmentation since they used mixed extents. But if you show the
results it may help.
