formating in SqlServer vs Reporting Services

All else being equal, is it faster to use functions like ROUND and TRIM
in the SELECT statement of the query and let the db process it or to
set formating in the layout of the report and let Reporting Services
handle it?
In my case, all is not equal. We have the DB on a very powerful machine
that at sometimes is very overtaxed and runs smoothly at others. RS is
moving to a decently powerful server that it will have exclusively.
Thanks

can be handled in the presentation layer (i.e., RS) using format strings.
TRIM isn't necessary unless you have some smokin' character columns...

Format to 2 decimal places?

Hi, i need to display my data in 2 decimal places but now i'm getting results after some calculation (for eg. 2.336224). How can i round it off to 2.34?

Hi,

In the report designer, right click the cell where you want to display the above number then go to properties and then to the format tab and enter Format Code as "0.00". It should format the 2.336224 to 2.34.

Hope it helps.

Format Numbers

I have a report that returns a column with number values that I want to round
to 1 decimal place. I am able to do this using the format expression #,##0.0.
However, some line items have a null value. For these line items I need to
display "-".
However, I need to do it using a format expression so that when the report
is exported to Excel the column won't be automatically converted to a string
value. Does anyone know if this is possible?Hi,

This worked for me:
Concatenate a zero to the value...
=IIF(Fields!YourData.Value + 0 = 0, "-", Format(Fields!YourData.Value,
"#,##0.0"))
HTH!
Kind regards - Fred|||Hi Fred,
Thanks for your prompt reply! I have tried your method. This works OK in
terms of the format in the report, however, when I export the report to MS
Excel 2003, the column value is automatically converted to a text string, and
therefore no number operations such as SUM or AVERAGE can be performed on the
column. Is there a format expression I can use on the column in the report
that will prevent this from occuring?

Can you take the nulls out in the database query side instead? i.e.
an expression like YourData = isnull(t1.number_column,0) in SQL Server.|||Hi...

..and/or maybe display a "zero" instead of the "-" which is most likely why
Excel is seeing strings.
Regards - Fred|||Hi again Fred,
I can't display 0 instead of nulls because the column is displaying an
average. Therefore, to display a 0 would be incorrect, and would also affect
any aggregation computations performed on the column such as an overall
average of all line items. Do you possible know of any other ways?
