Hi,
1. You can always write a stored procedure, wherein you can use cursor to concatenate the output of some SQL query. This string can then be returned / stored in some temporary table, which will be used later.
Support123 wrote: Is it possible to select only the top 3 (ordered by Modified Date DESCENDING) for each Owner???
like:
SELECT TOP 3 Owner, DocumentPath
FROM #tempTableDocPath
ORDER BY Owner ASC,Modified DESC
BUT for each owner show top 3 (if they have three)
AND then Is it possible ONCE AGAIN to CONCATENATE the DocumentPath column into one column (in a new table / tempTable)?
like this:
Owner - DocumentPath
1 - c:\reports\fileAc:\reports\fileBc:\reports\fileC
2 - c:\reports\temp\FileAc:\reports\fileAc:\reports\fileB
AND SO ON....
I didnt got this. Can you please clarify in details, what exactly you want in this case ??

i want to put all the rows where the owner is the same (example 1... owner 1 is repeated three times because he has 3 documents linked to him... so he would look like this in the db:
Owner - DocumentPath
1 - c:\reports\fileA
1 - c:\reports\fileB
1 - c:\reports\fileC)
what i want to do is take all the paths linked to this owner, and put them into one column... to look like this.
Owner - DocumentPath
1 - c:\reports\fileAc:\reports\fileBc:\reports\fileC
So you see, now i have all the values needed in one column. This makes it TONS easier to display on a report.
So Column 1 (Owner) would have the Owner id and the Column 2 (DocumentPath) will have all the DocumentPaths found linked to the owner in column 1. I hope this is more clear???

Yes, it is clear now.
Can you provide some table structure for a more precise answer ?
It would help me allot.

ALTER PROCEDURE dbo.SelectData2<br />
(<br />
@naam1 varchar(30),<br />
@naam2 varchar(30),<br />
@leeftijd int,<br />
@numberfound int OUTPUT<br />
)<br />
AS<br />
SET NOCOUNT OFF<br />
SELECT ID<br />
FROM vrienden<br />
WHERE Voornaam = @naam1 AND Achternaam = @naam2<br />
SET @numberfound = @@ROWCOUNT<br />
IF (@numberfound = 0)<br />
BEGIN<br />
INSERT INTO vrienden (Voornaam, Achternaam, Leeftijd)<br />
VALUES (@naam1, @naam2, @leeftijd)<br />
END<br />
IF (@numberfound > 0) <br />
BEGIN<br />
UPDATE vrienden<br />
SET Leeftijd = @leeftijd<br />
WHERE Voornaam = @naam1 AND Achternaam = @naam2<br />
END<br />
RETURN
I entered this Stored Procedure in VWD and it accepted it, however I wonder if it is possible to do a SELECT and an INSERT or UPDATE in the same procedure.
My question is, would this work? Or should I make two stored procedures one to find if a certain entry is already in the database and a second stored procedure to change the database?
Also I am not sure yet how to process an OUTPUT variable.
Please some advice.
Thanks! Ranger49

A stored procedure can contain as many CRUD operations as you like. However you should consider giving your stored procedures more meaningful names. For instance, your SP is called SelectData2 but it performs select, insert and update operations. Ideally, the name of the stored procedure should indicate its purpose.

You are right, but this was only my second attempt ever, so I called it SelectData2.
Would you know of an example where a stored procedure is called with OUTPUT parameter? I figure my attempt failed due to an error in the calling cs file, and that the Stored Procedure itself is fine.
I Googled it, and got some examples, but they weren't answering my question.

When you create the Sql parameter for the output parameter, you set its direction to Output or InputOutput. When you say it failed, what do you mean? Did you get an exception or did it not behave as you would expect?

Hi,
Can I connect with visual basic.net to a online server (I have a space on the server with my hosting company, the server has mySQL database on it.)?
If I can please tell me how (connection string, methods to use, namespaces etc...)
The idea was to totally work online using mySQL server?
Thanks.

You can and this[^] lists the connection strings you can use. Install the native MySql .NET provider and use this in your code. There are plenty of good tutorials for using this online.

You will have a master table as you have shown already and details table referencing invoice number (primary key) of the master table. Then you can add as many records against your primary as you want.
Your query will include an inner join with condition -- MasterTable.InvoiceNo = DetailsTable.InvoiceNo
Hope that answers your question.
You must be able to complete rest of the work.

i think your datatable should designed as follows:
ProductedId(pk) Products units TypeId
1 Nokia1600 2 1
2 Nokia1700 5 1
3 Nokia1800 6 1
4 Nokia2600 2 2
5 Nokia4600 8 2
6 Nokia8100 2 3
7 Nokia8300 1 3
8 Nokia56 6 3
9 Nokia1310 2 3
Connection string:
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\mydatabase.mdb;User Id=admin;Password=;
query sentence:
select * from products where typeid=x;
hope it will work as you wanted.

I want to trim the value so i just write a simple query
in MSACCESS 2000
SELECT Trim([ItemName]) AS Expr1
FROM Items
But it will give error "Undefind function "Trim" in expression"
What to do...?
Regards

There is no TRIM commmand in T-SQL you have to use LTRIM then RTRIM as follows:
SELECT LTRIM(RTRIM(ItemName)) Expr1 FROM Items
Regards
Guy
You always pass failure on the way to success.

Thanks for reply but still query is not working
Same error occurred for LTRIM function
SELECT LTRIM(RTRIM(ItemFullName)) as Expr1 FROM Items

How to add the reference...?
If I write LTRIM RTRIM in a query using C#.net and deploy the application to client site then same problem may occurred...?
