I would firstly look at why you have long transactions - there is probably a design flaw somewhere. SQL Server is designed to work with many clients performing simultaneous updates without the need for the developer to attempt to control locking under anything but very exceptional circumstances.
I have been asked about this in the past and it has usually been because the developer either didn't really understand how SQL Server locking works, or they felt they could do a better job than the guys who wrote the code at Microsoft.
If you really want to do it yourself then may I wish you luck, and your end users a lot of patience

Hi all,
I am getting an 'incorrect syntax near StoredProcName' error on debugging the beginings of my web app.
I know the sql syntax is correct as I have tested it in management studio express(2005) annd it returns exactly what I expect. The error is only occuring when calling from my page.
Here's my page code followed by a very simplified stored procedure(I know my complex one will return the correct result and this has the same error).
Page code:
SqlConnection conn = new SqlConnection(connString);
string sPName = "getProjectProModules2";
SqlCommand cmd = new SqlCommand(sPName, conn);
SqlParameter par1 = new SqlParameter("@modCount", SqlDbType.Int);
par1.Direction = ParameterDirection.Output;
par1.Size = 1;
cmd.Parameters.Add(par1);
SqlParameter par2 = new SqlParameter("@singleModule", SqlDbType.VarChar);
par2.Direction = ParameterDirection.Output;
par2.Size = 20;
cmd.Parameters.Add(par2);
conn.Open();
SqlDataReader recaffected;
try
{
recaffected = cmd.ExecuteReader();
if (recaffected.HasRows)
{
int i = 0;
while (recaffected.Read())
{
if (i == 0)
{
string countStr = cmd.Parameters["@modCount"].Value.ToString();
count = Convert.ToInt16(countStr);
}
moduleList[i] = cmd.Parameters["@singleModule"].Value.ToString();
i++;
}
recaffected.Close();
recaffected.Dispose();
return moduleList;
}
else
{
moduleList[0] = "No Modules";
return moduleList;
}
}
catch (Exception ex)
{
moduleList[0] = ex.Message.ToString();
moduleList[1] = ex.Data.ToString();
moduleList[2] = ex.Source.ToString();
return moduleList;
}
finally
{
conn.Close();
conn.Dispose();
}
SP Code:
ALTER PROCEDURE dbo.getProjectProModules2
@modCount int OUTPUT, @singleModule varchar(50) OUTPUT
AS
select '1'
RETURN
If I don't put the parameter size in my page code, it errors saying invalid parameter size.
Really not sure whats going wrong, I've looked up the code all over the place and from what i can see I'm doing it right. Anyone have any idea what the problem is?
Thanks in advance.
Mark
OK, fixed that error for those interested, I was not setting the command type to be StoredProcedure. However, I only seem to be able to return null as my parameter values. Still if there's any suggestions I would appreciate it.

To return parameters, you create local variables and pass them to the parameters, from memory.

OK, so I have created 2 local variables, 1 int and 1 string, these I am passing to the paramater as the value,
I.E.
string singleModuleStr = "";
int countInt = 0;
--it doesn't like me not assigning them....
.....
par1.value = countInt;
.....
par2.value = singleModuleStr;
do i then assign the par2.value etc to these variables at recAffected.Read()?
Don't want to sound dumb but I'm used to just returning a select list and I want to be able to do it each possible way to broaden my knowledge.
Thanks for the help so far.

Hey there,
I'm having a little issue with a query. Basically I'm trying to do some paging. There's many ways to do it, I know, but what I came up with was this:
SELECT TOP 10 columnA, columnB
FROM table
WHERE columnA not in (
SELECT TOP 21190 columnA
FROM table
ORDER BY columnC DESC)
ORDER BY columnC DESC
Some notes about it:
columnA is the key
columnD, columnC and columnA are index1
columnD and columnA are index2
columnC is index3.
In SELECT TOP 21190, that number is pageNumber * pageSize
Now... it seems that the very last 'ORDER BY columnC DESC'is the problem. Like it is the query takes around 1 minute to run. If I take that line out, the query runs in less than a second. Or, if I change the ORDER BY to be done by columnA, it also runs in less than a second.
Any ideas?

You need to do an order ASC in one of those queries for this to work. Then you don't need the 'not in', which is your problem. Select in desc order, ending with the first record you want. Then select in your outer query the number you want, in ASC order.

Hi, I want to debug a stored proc on our server but the database contains close to 30k stored procs. So when I press the expand button on the server explorer pane I have to wait for at least 30 minutes before VS unfreezes... This is getting quite annoying...
Out of these 30k stored proces around 95% are useless to me so I would like to filter them by their names.
All the ones I don't want start with 'zDP_'.
Do you know if there is a way to apply a filter before pressing the +?
Alternatively, is there another tool I could use to debug my stored procs?
We are running SQL Server 2005.
Thanks
Fred

hi friends
i have a server that installed o it a sql server 2000
i want to create a connection to the database on this sql server.
my server name is (local);
when i try to login into my database from query analyzer:
i type "(local)" instead of server name and username and password of a auser that i created for login to database.
its worked correctly.
but when i try to do this action from my home pc, an error appear that contanis below message:
"Sqlserver does not exist or access denied."
i enter my server ip instead of "(local)" in my query analyzer from my home pc.
now how can i login to my database from my home pc????
what do i enter server name ? an ip address or else???
please help me
nobody help you...
you have to help you yourself
and this is success way.

(local) only works if you are logged in locally to the machine where the instance of SQL Server is installed. You will probably need to use the IP address of the machine from home, unless you have some way to resolve the hostname (like if you are logged in thru a VPN). Then you can type in your username and password into QueryAnalyzer just like you would if you were on the machine locally.

Thanks for sharing!
The latest version looks good; I am considering upgrade to this 2008 version.

How can i pass the parameters to triggers?
|
|
|
|
|
You don't. The trigger has all the data from the insert/update/delete in special tables called inserted and deleted. Google triggers and yuo will find plenty of examples.
Hope this helps

If you cannot find a simple enough article to explain SQL security then perhaps you would be better off employing someone who does understand it to set up the security on your system. The saying 'a little knowledge is a dangerous thing' is very applicable to security.
