Hello everyone,

I have a MS SQL Server 2005 Express Edition and I want to restrict Login access to the database to only one specific domain account. How can I do this any ideas? because when I went to try and create a windows login and specified the domain account that I want it worked ok, but when then I tried to Login into the database again with a different domain account to test it still let me in. Is there some particular setting that I don't know about that anyone can help me with?

Thank you very much.

Put the database in teh from clause:

select * from [database].[owner].[tablename]

select * from nortwind.dbo.customers

You can ommit the owner if you want:

select * from northwind..customers

The responses you have assume that the databases are on the same server, in which case database.owner.tablename will work. If they are on different servers you have a problem, you need to set up linked servers, something I hate doing as the server is then hard coded into the query.

How to Sort this Data

Good Day All

i have a Simple Query

select id,NodeID,Description,refParent from #nodes2

order by id ,refParent,description

this shows the following data

ID     NODEID	        DESCRIPTION           REFPARENT

======================================================================

0	149		Compulsory	        NULL

1	155		One of		         0

2	156		GunningM                 0

3	157		JonesJ		         1

4	158		One of		         0

5	159		D1127	                 4

if you can look in this table the Records ID 5 and 5 are fine but this record but

2	156		GunningM      	        0

is supposed to be under its parent which is the one with ID 0, so i want to sort it so that it can have the following results

ID     NODEID	        DESCRIPTION           REFPARENT

======================================================================

0	149		Compulsory	        NULL

2	156		GunningM                  0

1	155		One of		         0

3	157		JonesJ		         1

4	158		One of		         0

5	159		D1127	                 4

Thank you

Your question makes no sense whatsoever.

Why should record ID 2 come above record id 1? There is nothing there that could possibly identify the fact that it should do.

And besides, your order by gives prescendence to the ID column:

order by id ,refParent,description

So even if there was something (such as an ordinal column) it would be ignored.

If there is a fake order that children must come in, then you will need to add a column for this and order by that column.

The record

2	156		GunningM      	        0

is a Child of the Parent 0 and it has no Children. So there are other records that have REFPARENT of 0 but they have children. So if the record has no child it must come close to its parent.

Your ordering is wrong, you are ordering by id first so your results are in the correct order. To get the results you want, you will need to change the "order by" settings; probably to refParent first, then by id descending.

Can you please explain the criteria that cause the records with ID = 2 and ID = 1 to sort that way? Is it because there is no reference to that ID? Thanks.

let me Explain again. Here is my SQL Query that Produces that table till the end.
The First part that i run is this

Create table [#Nodes]
(id int IDENTITY(0,1),
 NodeID int,
 parent int,
 [Description] varchar(128),
 refParent int
)

INSERT INTO #Nodes
   (NodeID, Parent, [Description])
select distinct n.ID NodeID, n.Parent, nTyp.Descr [Description]
from tbl_node n
inner join tbl_node_type nTyp on nTyp.ID = n.Type and nTyp.Descr in ('Compulsory','One of')
where n.curr = 10 
union
select distinct n.ID NodeID, n.Parent, m.Descr [Description] --, n.Type, n.Curr, m.Descr 
from tbl_node n
inner join tbl_node_type nTyp on nTyp.ID = n.Type and nTyp.Descr = 'Subject'
inner join tbl_modl m on m.id = n.modl
where n.curr =10

and it Produces the table #Nodes with the Following Records

ID  NODEID	PARENT                DESCRIPTION		REFPARENT
=========================================================================
0	149		NULL      	Compulsory		NULL
1	155		149	        One of			NULL
2	156		149		GunningM		NULL
3	157		155		JonesJ			NULL
4	158		149		One of			NULL
5	159		158		D1127			NULL

and in the next statement i create another temp table

select distinct  nP.id as [id], nP.NodeID, nP.parent, nP.Description, nRef.ID refParent 
into #nodes2 from #Nodes nP
left outer join #Nodes nRef on nP.Parent = nRef.NodeID	-- look up the reference id of the parent
order by  refParent,nP.Description

and the temp table #nodes2 will look like this

ID     NODEID	       PARENT         DESCRIPTION	    REFPARENT
============================================================================
0	149		NULL	       Compulsory	      NULL
2	156		149		GunningM		0
1	155		149		One of			0
4	158		149		One of			0
3	157		155		JonesJ			1
5	159		158		D1127			4

and i made a mistake here by posting a query without a parent Field, to modify that it looks like this

select id as [id2],NodeID,parent,Description,refParent  
 from #nodes2
order by  nodeid,parent, refParent

That way you are ordering is not correct. Change the order by clause as per your preferences.

If this had been Oracle, it would have been a walk in the park:

SELECT *
FROM nodes2
CONNECT BY PRIOR Id = RefParent
START WITH RefParent IS NULL
ORDER SIBLINGS BY Id

If you have SQLServer 2008, this query might work: (Havent tested)

WITH records AS
(
    SELECT
        Id,
        RefParent,
        CONVERT(VARCHAR(MAX), ROW_NUMBER() OVER (ORDER BY Id)) AS thePath
    FROM  nodes2
    WHERE RefParent IS NULL
        UNION ALL
    SELECT
        n.Id,
        n.RefParent,
        r.thePath + '.' + CONVERT(VARCHAR(MAX), ROW_NUMBER() OVER (ORDER BY n.Id)) AS thePath
    FROM records r
    JOIN nodes2 n ON n.RefParent = r.Id
)
SELECT *
FROM records
ORDER BY 
    thePath

There are times when I really hate Oracle, but when you're working with trees it really is SO superior to SqlServer

Here's My issue:
I have 4 Tables

Author                   BookAuthor
---------               --------------
ID                       BookID
AuthorFirst              AuthorID
AuthorLast

Book                     BookNumber
---------               --------------
ID                        ID
Title                     BookID
Price                     SurrogateNumber
Retired
Keywords


author.id linked to bookauthor.authorid
book.id linked to bookauthor.bookid
book.id linked to booknumber.bookid

I don't understand how to get all my records that have instances in BookNumber. Basically what is happening is I have 94 rows so far in booknumber (which is what i want), but since booknumber contains duplicate bookid's i only get a totaly of 86 rows back when i do the following:

var options = new DataLoadOptions();
                options.LoadWith<Book>(c => c.BookAuthors);
                options.LoadWith<BookAuthor>(c => c.Author);
                options.LoadWith<Book>(c => c.BookNumbers);



                db.LoadOptions = options;
                
                books = db.books.tolist();
                bookbindingsource.datasource = books;

and whenever I look in the database 86 books are in books (so that is right) because i have duplicates that were added to booknumber to make it the total of 94.

So my question is how do i get all 94 books instead of just the 86?
I tried this but its obviously wrong because I got like 116 results Frown | :(

var RightJoin = from b in db.Books
                                join ba in db.BookAuthors on b.ID equals ba.BookID
                                join a in db.Authors on ba.AuthorID equals a.ID
                                join bn in db.BookNumbers on b.ID equals bn.BookID into bookandBook
                                from bn in bookandBook.DefaultIfEmpty()
                                select b;
                bookBindingSource.DataSource = RightJoin.ToList();

I just want to be able to show every single book I have entered in the database where it has a unique surrogate number. In the current case only 94 books...
