So a basic dynamic pivot then?
DECLARE @cols As nvarchar(max), @query As nvarchar(max);
SET @cols = STUFF
(
(
SELECT DISTINCT ',' + QUOTENAME(Site)
FROM Source
FOR XML PATH(''), TYPE
).value('.', 'nvarchar(max)')
, 1, 1, ''
);
SET @query = N'SELECT DataPoint, ' + @cols + N' FROM Source PIVOT (COUNT(Site) FOR Site IN (' + @cols + N')) As p';
EXEC(@query);

Could you help with XML select. Below is my xml however it won't select correct value.
DECLARE @input AS XML
SET @input =N'<?xml version="1.0" encoding="utf-16"?><NewDataSet><GroupID>111111</GroupID><GroupID>111111</GroupID><GroupID>999999</GroupID><GroupID>777777</GroupID></NewDataSet>'
SELECT
Ppl.GroupID.value('(@GroupID)', 'VARCHAR(6)') AS 'GroupID'
FROM
@input.nodes('/NewDataSet/GroupID') as Ppl(GroupID)
|
|
|
|

I do not understand what do you mean by (@GroupID), but you should write it like this:
Ppl.GroupID.value('.', 'VARCHAR(6)') AS 'GroupID'
I'm not questioning your powers of observation; I'm merely remarking upon the paradox of asking a masked man who he is. (V)

for example
Abul
Azar
Mohamed
Sheik
vazith
i want to select names from azar to last record of the table
|
|
|
|
|
SELECT *
FROM Table
WHERE Name >= 'Azar'
For this query to be efficient, the table should be indexed on the name column
|

use PARA2;
with pel(reg,inst,nama,alamat,sts)
as (select p.ID_Pelanggan
,p.No_Pelanggan
,p.Nama_Pelanggan
,p.Alamat
,case when p.Status_Pelanggan=2 then 'Aktip'
else 'Non Aktip'end'Status'
from PELANGGAN p),
ganti(reg,ml,nml,mb,nmb,thn)
as (select g.ID_Pelanggan
,g.Meter_Lama
,g.Nomor_Lama
,g.Meter_Baru
,g.Nomor_Baru
,g.Tanggal
from GANTI_Log g)
select p.reg
,p.inst
,p.nama
,p.alamat
,p.sts
,g.ml
,g.nml
,g.mb
,g.nmb
,g.thn
from pel p left outer join ganti g
on p.reg=g.reg
order by p.reg

What do you mean with "last row" - is it the row with newest date (g.Tanggal), and what would you like to select if no entry is present yet?
What about
...
as (select TOP 1 g.ID_Pelanggan
,g.Meter_Lama
,g.Nomor_Lama
,g.Meter_Baru
,g.Nomor_Baru
,g.Tanggal
from GANTI_Log g
Order by g.Tanggal desc
)

Bernhards solution is valid for SQLServer.
But what if you don't use SQL Server?

Hello Experts,
I have a table ID, Lock and other fields. I have a VB.NET program that gets the TOP 1 record that is not lock and lock that record to be keyed/entry. Multiple users will use this program, is it possible that more than one user can access the same record in this process? Its possible users will request a record at the same time.
Thanks a lot.
Revision
Table
ID | Lock |
------------
1 | False |
2 | False |
3 | False |
Lets say that 2 computer are using same program connecting to the same server database
Client:1 - Request Time: 10:30:00 will get the ID 1, ID 1 will lock(update to true)
Client:2 - Request Time: 10:30:05 will get the ID 2, ID 2 will lock(update to true) - cause ID 1 is lock
This is my question. same request
Client:1 & 2 - Request Time: 10:30:00
- Query is (SELECT TOP 1 * FROM Table WHERE Lock = False)
- Put ID to a variable
- In the above run time, Is the 2 client will get the ID 1 or the this query will stack on SQL Server will finish one query first before executing another query?
- Be who you are and say what you feel because those who mind don't matter and those who matter don't mind.
- Most of the problem in your life are due to two reasons: you act without thinking, or think without acting

I don't understand your question. How are you locking the record?
There are only 10 types of people in the world, those who understand binary and those who don't.
|
|
|
|
|
I think you will need to write your own locking mechanism. No big deal.

Probably. Does not mean that it will be a problem.
There's a lot of stuff written on locking in SQL, with topics like lost updates[^] and dirty reads (no, not those magazines). You can add various hints[^] to the query. MSDN has dedicated a section[^] to consistency and concurrency.

What business case do you have that requires you to lock it?
|

If I understood your question correctly, you're wondering if session 1 can read the data that session 2 is locking. If this is the concern then the answer in many cases is no.
Consider the following scenario:
Session 1 Session 2
--------------------------------------------- -----------------------------------------------------
Select record A, field named SomeValue is 1
Select record A, field named SomeValue is 1
Begin transaction
Update record A,
field named SomeValue is set to 2,
an eXclusive lock is taken
Select record A, record is locked, session 2 waits
Some other modifications
Session 2 still waits
Commit the transaction, lock is freed
Session 2 now gets the answer,
field named SomeValue is 2
(the value session 1 updated)
Now the actual sequence varies depending if auto-commit is on and so on. Also you should know that if row versioning is in effect, then the behaviour is far different. For more information, read Data versioning in SQL Server using row versions[^]

Hello !
I have created an application that use a sql server database.
But the problem is that a user can open sql server management studio and can do anything that I don't like , for example :
1) Can modify values inside tables.
2) can delete records
3) Can see and can get my database structure.....
......
How can I protect my database , so that users can modify this database only inside my application , and can do anything outside my application ? I don't know does exist a way to protect my database with a password or.... ??? for example when I was using Access for database , i have protected Access files with a password , and after only my application can open this database .
Is possible to include a protection in the sql server database file ( so even the file is imported to another computer to remain protected ?
I have a specific situation :
My application is designated to manage several "office".
In my application folder , i have a empty backup file ( offline) of my database called "Model". And inside my application a user can create "A new office " and when he do this the application restore a copy of "Model" inside sql server with a specific name (for example "Office1". Another time the user can create another "Office" using again a copy of "Model"
So inside Sql server may be different databases ( all of them with the same structure ) like "Model"
So in this situation how can i Protect my databases and the "Model" .
Because i think i should apply a Protection" inside the offline backup file "Model" ( if it's possible , all the databases that have created from "Model" will have the protection ) or ??????
What should i do in this case ?
Thank you !

If your users have SA rights using windows authentication then you cannot stop them.
However you can restrict user access by implementing a reasonable security/password profile within SQL Server.
I hate to just dump a link but the subject is way too large for a forum discussion, do some research into SQL Server Security[^]

Consider that they can open Explorer and do things you don't like. Or open the physical PC and do things.

is there a way to protect the mdf file ?

Not really. The local admin has all the rights on the machine. The person that owns the server, owns the databases, and the data.
Buy a good server, install it SQL Server, put it in a large box, lock it, and hand that to the customer. That way you would be the local admin.
Or host the server from your place, and have them connect to your "SQL Cloud".

if you have read my case , what can I do with "Model" file that is offline ? Someone can get and restore to another PC.
I read somewhere about encrypting the database.
Is this true and how can be done.Can this be a help in my situation ?

You can encrypt the sprocs, and/or the data. Both will not protect your database-schema.
