"SUM" of a varchar column?

I have a table that contains a number of columns containing either a varchar
value, or null. There are multiple rows per grouping. I would like to colapse
the multiple rows into a single row, either by appending the strings to each
other, or simply selecting the first (or last) one.
If it was a number field I could do a SUM, MAX or MIN. SUM doesn't work, for
obvious reasons. I thought MAX would work, but MAX returns only one value for
all of the columns (as opposed to one per column) and the rest are left as
null.
Any suggestions?
Here's an example...
The table contains this data, all items are varchar
32611317
3261Non-Client
32612
3261mmarkowitz
I'd like to turn this into...
3261 1317 Non-client 2 mmarkowitz

I'm not sure if this will help, but you may want to take a look at the
GROUP BY WITH ROLLUP and WITH CUBE commands. It may work for what you are
after.
SELECT Col1, Max(Col2)
FROM tablename
GROUP BY Col1
WITH ROLLUP

Tough to pivot without an explicit attribute for the column.

Actually it is the RESULT of a pivot, which is why it is spread out
vertically like that.
But I did figure out a "trick". After reading the page you sent, I combined
their technique of ISNULL (instead of CASE) with MIN, and presto.
Thanks!

"Next Page" is extremely slow - like it's requerying

I have a report with a single dataset, 3-levels of table grouping, and
returns 5 pages. When I preview the report in VStudio, it returns the 5
pages and I can navigate the pages real quickly. The problem is, when I run
it online via the RS front-end and click "Next Page," it takes a good 30
seconds to load the subsequent page or pages. The query itself runs in about
45 seconds, but why is the paging not near instantaneous?
Thanks,
jI hope you must have asked some questions yourself like
1. Is this report is slow or all the reports are slow?
2. Is your dev environment and production is different then how fast is your
production machine, is the machine slow (database server)?
3. Is Cache enabled/disabled ?
4. Are you doing the dev and online chking on the same machine ?
Probabily you can go to configuration from RS manager screen and check for
the cache options.

1. This report is slow. All the other reports paginate just fine, even those
that use the same datasources.
2. It's a production machine.
3. It's not caching a temporary copy, but neither is any of the other
reports. I set the caching (every 10 minutes) and it's 99% faster, but I
still don't understand. The report shouldn't refresh itself on every page,
only every time it is run.
4. Yes. Would this really matter?
Thanks,
j

"Hide Duplicates" within Details Grouping

I'm having problems using the "Hide Duplicates" function within the Details
Grouping of a table in a report (using RS SP2, SQL Server 2000, Visual Studio
2003).
The details grouping has two rows, set out as follows:
| CallFlow Name |
| | Outcome Type | Grammar Type | Meaning | Totals
There are about 10 different "CallFlows", each of which is displayed as
above. There are several possible "Outcome Types"(Success, Fail, Hangup etc),
and I want to prevent duplicates within the scope of the Callflow as shown
below:
| CallFlow Name 1 |
| | Success ...
| | Success ...
| | Success ...
The problem is, when setting "Hide Duplicates" for "Outcome Type", it hides
*ALL* of the duplicated information even in the next Callflow. Is there a
conditional expression or formatting that can be applied to this field so
that duplicates are only hidden for that particular table?
ThanksAll the fields should be in one row of the report layout table.
| CallFlow Name | Outcome Type | Grammar Type | Meaning | Totals
In the table's properties, add a group for the CallFlow field.
In the CallFlow cell's properties, click on the Hide Duplicates dropdown
and select the new group created.
