The only manipulation that I am doing is in a table I am summing values for a total row. Do you know if Visual Studio Developer edition has those performance tools? How are they accessed? I am great at creating the reports...just ignorant when something like this goes wrong.
Thanks,
Bryan

This article[^] gives you some more information. It is only a feature in Team System though.

Bryan - run the Sql Profiler against your server to see what's going on. This[^] article details what to set up.
Deja View - the feeling that you've seen this post before.

I know this q is very elementary but here it goes.
I'm trying to run a subquery on this table to get the name from ReportsTo Column
EmployeeID Name Hired reportsto
1 Ms. Davolio Nancy May 1 1992 2
2 Dr. Fuller Andrew Aug 14 1992 2
3 Ms. Leverling Janet Apr 1 1992 2
4 Mrs. Peacock Margaret May 3 1993 1
This query doesn't seem to work
Select Name, (select name from employees where employeeid = reportsto) as 'ReportsTo' from employees
Please advice

You were close. You need to reference the inital table in the subquery for it to work.
SELECT
Name,
(select name from employees where employeeid = e.reportsto) as 'ReportsTo'
from
employees e
Better set logic (should be faster on large tables):
SELECT
e1.Name,
e2.Name as ReportsTo
FROM
employees e1
LEFT JOIN
employees e2
ON (e1.reportsto = e2.employeeid)

Hi,
I have a table, userprofile(fname,lname,address,hobbies). Hobbies is multiple selection from the list box, which binds data at run time. I want to select multiple hobbies and insert it into one single row. I have a faint idea od using a for loop for this purpose. Can you please help me?
Regards,
Anuradha

What you should really do is normalise your db and have your tables like this
userprofile(UserID, fname,lname,address)
hobbies(UserID, Hobby)
|
|
|
|
|
First of all, thanks you for the prompt reply. I actually thought about this earlier- having a user table and a hobby table and another user_x_hobby table where I can insert the Userid against the HobbyId. But then my question was, what query I could run on this. I am new to .Net/SQL and trying to explore new possibilities.

Anuradha

How do I use WebServices as a datasource for my reports? I see where you create a datasource there's an option for "xml". Has anyone used "WebService" to create a custom dataset data extension, and if so how do you do it?

Remote Server May be down or the Sql Server service may be stopped...

If you are facing connectivity issues after ensuring that the SqlServer service is started, probably you might want to take a look at the following factors
1) I've noticed that the datasource taking params like ipaddress/SqlServer2000 (read it as ipaddress slash sqlserver2000) or
machinename/SqlServer2000 (assuming that in both cases you are having SqlServer 2000)
2) If you are using SqlServer2000 and if you have tried the above mentioned option and still experiencing connectivity issues, probably resetting protocols using "sql server client network utility", try disabling and re-enabling TCP/IP and Named Pipes.

Suppose I have the following stored procedure
CREATE PROCEDURE dbo.GetContacts
AS
SELECT ContactID, ContactName FROM Contacts
GO
Then I can execute the stored procedure as follows:
EXEC dbo.GetContacts
How can I receive the returned results into a temporary or permanent table?

Using Into Clause
Into Temporary Table
----------------------
SELECT ContactID, ContactName INTO #TempTable FROM Contacts
The above sql stmt will create a temporary table and Inserts the resulting rows from the query into it.
Into Permanent Table
----------------------
Insert Into PermanentTable(ContactID, ContactName)(SELECT ContactID, ContactName FROM Contacts)
this statement Inserts the resulting rows from the select query into permanent table provide both the tables should have the same definition.

Actually what I meant is that I want to use the stored procedure to populate the table. I already found a way:
CREATE @TmpTable (ContactID INT, ContactName NVARCHAR(36))
INSERT INTO @TmpTable EXEC dbo.GetContacts
SELECT * FROM @TmpTable
Thanks all the same.
|
|
|
|
|
<br />
CREATE TABLE #TEMP (ContactID int, ContactName varchar(50))<br />
<br />
INSERT #TEMP<br />
EXEC dbo.GetContacts<br />
<br />
SELECT * FROM #TEMP<br />
<br />
|
|
|
|
|
create Function [dbo].[MyFun] ()
Returns @tbl table (id int,Item varchar(100))
as
begin
insert into @tbl
SELECT ContactID, ContactName FROM Contacts
return
End
then use this
insert into temporary table/permanent table
select * from MyFun()

Hi,
This is closely related to my previous question BUT ...
I go through a web log file and extract each line and put the data into a new row in a datatable.
I then change the data in one field of each row.
I then use that datatable as my source for extracting various statistics.
At no time do I really need to save the datatable to the underlying database as far as I can see.
If I don't need to save the datatable to the database, do I really need to do a datatable.update let alone a dataset.acceptchanges?

If you only need to use the DataTable object as an in-memory repository for data, then you don't need to use these methods. They are used for synchronising the contents of the DataTable with an underlying database.

Thanks for that - it's funny how I have never stopped to think about what I was doing until performance became an issue. Suppose this is often the case now that I think about it.
Just one thing more though...
Is there any need at all to call dataset.acceptchanges() if you have just done a datatable.update and you know there hasn't been any other changes to the datatset.
Logically the answer is no but I just want to confirm that.
Thanks for your time.
