Filter a Dataset with the Range (inc.) operator

It seems that when I use the Range(inc.) as the filter operator for a Dataset and then try to use the Last and First keywords to extract the results from the dataset in the layout the results are sometimes wrong and don't match the expected.

Does anyone knows of any issues that would affect this filtering mechanism?

That is because your results are not sorted by appropriate fields. If you want to use First(field1) and you have filtered on range of field1, then you must sort by that field to get correct values for first and last values.

|||Thanks for you answer, although it was not exactly what I needed but
nevertheless I was able to resolve this problem.
The solution lies in not choosing setting as a field the one you want to filter over,
with the range operator.
I don't know if that makes any sense but it worked for me.sql

fileLen function in stored procedure

Heres an extract of a stored procedure creating a column.
Path = FileLen([CacheServers].[CachePath]+
(left([DOCUMENT]. [PHYSICAL_DOC_GUID],6))+''''+[DOCUMENT]
.[PHYSICAL_DOC_GUID]+[DOCUMENT].[FileType])
Reult:
\\comp-ap- 70c\Imxxs$\data\docs\70393C\70393CE0EC6D
11D8BB64000D568A4637.tif
The above is a file path of an image stored on the SAN server. The code
above works perfectly fine in MS Access but not in SQL server 2K
It should return the size in bytes of the file.
Books online state the VBA function fileLen() works in SQL Analyser,
however, when I execute the stored procedure I receive an error message
"FileLen is not a recognised function name".
I cant find a thing on the Microsoft Tech communities the specifically
relates to calling VBA functions in SQL.
Any ideas?
Learning SQL and AccessIs there something wrong with the LEN function? Or DATALENGTH?

Where does it say that?
If you really need to check for file sizes from T-SQL you should look at the
sp_OA* system procedures. I'd suggest using an appropriate client applicatio
n
to supply the values to the server.

You could use CLR for something like this.

file handling

Is there function in SQL to return just the filename. For eg.
if the filename is 'C:\test\job.txt' , i want to extract job from the
filename. Is is possible? Thanks in advance!There's nothing built-in but you can accomplish the desired result with some
Transact-SQL string functions:
DECLARE @.FilePath varchar(255)
SET @.FilePath = 'C:\test\job.txt'
SELECT REVERSE(LEFT(REVERSE(@.FilePath), CHARINDEX('',
REVERSE(@.FilePath))-1))
Hope this helps.

If the path is stored in a column, the T-SQL string functions (i.e.,
CHARINDEX, SUBSTRING, etc...) can be used to return just the name. Also,
there are a few undocumented extended stored procedures that can be used to
work with files using T-SQL.
