Hi friends

I have one Table called tblCategory.

I have three Column CatID, CatName, ParentID

I have many records in this Table

CatID CatName ParentID

1 Cat1 0

2 Cat2 1

3 Cat3 1

4 Cat4 2

5 Cat5 2

6 Cat6 0

7 Cat7 6

8 Cat8 6

9 Cat9 7

10 Cat10 7

11 Cat11 8

Here I have Main Category which has ParentID 0 [ Cat1 and Cat6 ]

I Have Sub categories of Cat1 Which has ParentID 1(CatID 1 of Cat1) [ Cat2 and Cat 3 ]

Cat 2 has also sub category with ParentID 2 (CatID 2 of Cat2) [ Cat4 and Cat5]

I want result looks like as

Cat1 Cat6 ->>>>>ParentID 0
- Cat2 -Cat7 ->>>>>ParentID 1(CatID of Root Cat1) and ParentID 6(CatID of Root Cat6)
- - Cat4 - -Cat9 ->>>>>PaerntID 2(CatID of Root Cat2) and ParentID 7(CatID of Root Cat7)
- - Cat5 - -Cat10 ->>>>>PaerntID 2(CatID of Root Cat2) and ParentID 7(CatID of Root Cat7)
- Cat3 -Cat8 -->>>>>ParentID 1(CatID of Root Cat1) and ParentID 6(CatID of Root Cat6)
--No record --Cat11

Can anybody give me solution?

Thanks

SQL select up to the last 6 dates worth of an order

Hi, assume I have two tables called Orders (ID, DateCreated) and a child table called OrderDetails (ID, OrderID, ProductID, Quantity)

What I need to do is calculate the average last 6 orders. Now if there are only 5 dates worth of orders I would need to know this value as I need to divide the sum(Quantity) by the number of orders - which cannot be greater than 6 previous orders. I have tried a few different select statements, but cannot seem to get the result I am looking for. Oh one other thing, I would be selecting these records by ProductID.

Any suggestions at all?

Thanks

I am not quite sure what you want your result set to look like. It would be easier if you gave a list of the resultant columns.

Are you looking for the last 6 orders of a particular product or simply the last 6 orders?

I need some help with a stored procedure, I have a table in my database that I am writing records to, specifically a BeginningDate field and EndingDate field. I want to be able to run a stored procedure that selects records based on a range of dates. This range of dates begins with monday and ends the following sunday, it covers an entire week. When I run the stored proc the where clause goes something like this:

<br />
select<br />
UserID,<br />
BeginningDate,<br />
EndingDate,<br />
<br />
From tableName<br />
<br />
where UserID = @UserID and BeginningDate >= @BeginDate and EndingDate <= @EndDate<br />
<br />

I know that it will not return any records if there is a date that is less than the EndDate. My question is how can I adjust this so it selects the one record based on a BeginDate and EndDate parameters?

select
UserID,

EndingDate,

From tableName

where UserID = @UserID and ((BeginningDate >= @BeginDate and EndingDate <= @EndDate) OR (BeginningDate >= @BeginDate) OR (EndingDate <= @EndDate))

Hope thats what you want ?

How to concatenate all columnB where columnA are the same? USING SQL 2005[modified]

Hi, i have data like this in temp table

Owner - DocumentPath
1 - c:\reports\fileA
1 - c:\reports\fileB
1 - c:\reports\fileC
2 - c:\reports\temp\FileA
2 - c:\reports\fileA
2 - c:\reports\fileB
AND SO ON....

i would like to know...
Is it possible to concatenate all DocumentPath column's into single column for each Owner ?

so i would have a new temp table that looks like this (if possible... this is still theoretical)
Owner - DocumentPaths
1 - c:\reports\fileAc:\reports\fileBc:\reports\fileC
2 - c:\reports\temp\FileAc:\reports\fileAc:\reports\fileB
AND SO ON....

The reason i want to do this is because i need all the file paths in one line in one field on a report later... I thought i could PIVOT the data and then concatenate them...

OR

Is it possible to select only the top 3 (ordered by Modified Date DESCENDING) for each Owner???

like:

SELECT TOP 3 Owner, DocumentPath<br />
FROM #tempTableDocPath<br />
ORDER BY Owner ASC,Modified DESC<br />

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....

Thank you in advance. I hope i put it all down clearly Confused | :confused:

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.

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???

Is this a viable stored procedure?

ALTER PROCEDURE dbo.SelectData2<br />

	@naam1 varchar(30),<br />
	@naam2 varchar(30),<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.
