I don't think that you can sign a SQL-database the way you sign a Word-document. A database is meant to be changed, if you want to restrict access then dive into permissions, users, passwords, policies and logons

Hi
I am using Visual Studio 2005 and C# to develop a Windows application in the cancer department where I work. It is a small patient management system. I was asked to use MS Access as the backend. For obvious reasons I would prefer to use SQL Server. Unfortunately the network guys running the hospital network are very sticky with what is allowed on their servers. This is quite understandable, but it does make things a bit difficult. We are only allocated a folder on the network that our department has access to. With MS Access it is easy enough. We just copy the MS Access database into the folder and point the application to it.
If I can use SQL Server how would I deploy it? Must SQL Server be installed on the server first? I will probably use SQL Server 2005 Express.
Thanks.

SQL server must be installed on the Server and you continue as usuall and point to SQl that Access and that means your Code will change in the DAL , you will be using sqlclient not oledb

Your'e network people are idiots (or have strict policies about what they can allow departments) . You need some arguments that will move them off this policy position or get an exception. They will have some database they use and may allow you to use part of it, may be oracle or one of the other enterprise DBs.
Our network team for instance will not allow Access anywhere near a server, it has been known to crash a server and they are terrified of it. Unless properly managed it can grow horrendiously. Are you sure you do not need to install the jet drivers or even office on the server? This would be a good argument against Access.
Good luck.

Hello everyone,
I've a exe file in C:\. I need to run it from stored proc using xp_cmdshell. Please note that I'm using SQL Server 2000.
My stored proc is :
Create proc callExe
As
EXEC master.dbo.xp_cmdshell 'C:\PrintToPDFConsole.exe'
After executing this, the output is :
NULL
Unhandled Exception: System.ComponentModel.Win32Exception: No application is associated with the specified file for this operation
at PrintToPDF.Program.Main(String[] args)
NULL
and the exe file did not run.
Please help in this.
Also, I've tried with common exe file like 'notepad.exe' like:
ALTER proc callExe
As
EXEC master.dbo.xp_cmdshell 'notepad.exe'
When I executed this, the execution is going on and not showing any output. The execution time is more that 10 mins and going on...
Then I forcefully closed the isqlw.exe from Task Manager.
Is that mean exe file can't be executed in sql server 2000 using xp_cmdshell ?

You cannot run exe which has GUI. You can run exe which is running in background process.

Yes, I forgot to write there that the exe file does not have a GUI.
It will automatically convert the any file to pdf file and save to My Document folder.

Hello,
My Question is related to SQL Server Memory Usage,
I have a VB.net application with MSDE.
When i run my application, the sqlserver.exe in Task Manager uses memory of about 20 MB,
Then when I View any Crystal Report created report, the memory goes on increasing as the report is loaded and if reaches about 150 to 200 MB, but even after closing the report and also closing the application, SQL Server does not release memory.
So when we again start the application, again memory goes on accumulating but is never released.
Memory is released only when we Stop and start the SQL Server or restart the PC.
Can anyone tell me how to make SQL Server Release Memory from my VB.net application.
Thanks in Advance.

Hello,
sqlservr.exe gives back never the memory except when there is a memory pressure, that's to say when the operating system is needing memory for itself or for another application. For example, SQL Server is releasing memory when too much paging is occuring.
When the operating system is short of free memory, sqlserv.exe frees RAM memory ( K. Delaney neede about 20 pages in her book (Inside Microsoft SQL Server 2005 : the storage engine ) to explain the
management of the memory by SQL Server.
You may limit the amount of memory used by a sqlservr.exe ( there is 1 sqlservr.exe for each started instance of SQL Server ) thru the options Min server memory and Max server memory ( right-click on an instance , properties, tab memory ). For my 3 instances, i have limited Max server memory to 500 MB, so i am sure that never a sqlservr.exe will use more than 500 MB ( in fact, it is rare that the 3 instances are running, so i am sure that, with 2 GB of RAM , i am sure that the OS and applications other than sqlservr will have at least 500 MB of free memory.
You can't manage and free memory from your VB.net application.
But a connection to a server or database is one of the heaviest operation and i prefer to limit the number of connections by opening the connection once ( at the beginning of the application ) and closing the connection when exiting the application ( don't forget to close the connection in the exceptions treatement )

Hi
While installing SQL Server 2008, it asks for Service account and account name, pls click: [^]
Here, what are the meanings of options: "NT AUTHORITY\SYSTEM", "NT AUTHORITY\NETWORK SERVICE" etc..?
Are these registry keys or something like that. Where can i find information about this stuff?
I don't even know which subject they are related and where i must start to search about these.
Ihanks...

A simple table:
create table temptable(userid int,username varchar(100),score int)
Values inserted:
insert into temptable values(1,'BOB',17)
insert into temptable values(1,'BOB',21)
Test:
select * from temptable where userid =1
Result:
1,BOB,17
1,BOB,21
Returns 2 rows. Fine.
The requirement: Find number of times BOB has scored above 20.
Expected result
1,BOB,1
My attempt:
select userid,username,count(*) from temptable where userid=1 group by userid,username
Here how do I specify a condition for the "Count()"? It just need to count score>20 for BOB.
I'm a rock bottom sql noob. Any help?

Try:
select userid,username,count(*) from temptable where userid=1 and score>20 group by userid

ed5756 wrote: select userid,username,count(*) from temptable where userid=1 and score>20 group by userid
 imagine if BOB doesn't have any record that has score over 20. It won't return any result at all. May be I should have stressed that point. In this case, the result should be like :
1,BOB,0
So I'm clear with my question now?

OK, you want to return a 0 if there are no scores over 20. That is trickier.
This will return the count of Bob's scores over 20:
Select userid,username,count(*) as [count] from temptable where userid=1 and score>20 group by userid
This union query will return that same result and also a dummy record with a 0 count:
Select userid,username,count(*) as ct from temptable as a where userid=1 and score>20 group by userid, username
union
Select top 1 userid,username,0 as ct from temptable as b where userid=1
One would think then that using the MAX function in a sub-select would get your desired result:
select userid,username,max(ct) as
from
(Select userid,username,count(*) as ct from temptable as a where userid=1 and score>20 group by userid, username
union
Select top 1 userid,username,0 as ct from temptable as b where userid=1)
group by userid,username
But I find that in T-SQL for some reason it throws an error. However, if I first define a view based on that union, then this works:
select userid,username,max(ct) from view_c as Over20 group by userid, username

Sorry, there was a typo in my last post. That query should have read
select userid,username,max(ct) as Over20
from
(Select userid,username,count(*) as ct from temptable as a where userid=1 and score>20 group by userid, username union Select top 1 userid,username,0 as ct from temptable as b where userid=1) group by userid,username
I have run the 2-step solution using a view on SQL Server and it works.

Yeah thanks. Also the one provided by Jorgen is also cool.

Something like ?
select * from
(select userid,username from temptable where userid=1 group by userid,username)as a
inner join
(select userid, count as cnt from temptable where score>21
group by userid)as b on a.userid=b.userid
But this doesn't work too

Got it almost!
select * from
(select userid,username from temptable where userid=1
group by userid,username)as a
left join (select userid, count(*)as cnt from temptable
where score>21 group by userid)as b on a.userid=b.userid
But this returns "NULL" instead of 0. How can I make it 0 ?
Can I use "CASE" on the count? Like:
CASE cnt when NULL then 0 END

How about:
SELECT DISTINCT userid
,username
,(SELECT Count(*) FROM temptable t2 WHERE t1.userid=t2.userid AND score > 20) as topscorecount
FROM temptable t1
WHERE userid = 1
