Use Stored Procedures sp_addlogin, sp_adduser and sp_addrolemember
|
|
|
|
|
In SQL Server 2005, it is preferable to use CREATE LOGIN, CREATE USER instead of sp_addlogin, sp_adduser.
They will be removed in future versions of SQL Server.

Hi All,
I have wrote stored procedure which calculates points for result for around 1000 users.
This procedure takes no parameters from asp.net code.
asp.net code is used for just for calling this procedure. But when I run this procedure from the code it gives me the timout error.
while running from the sql server itself it works fine.
Kindly tell me how can I overcome this problem?
Below is my code, which is giving me the error.
try
{
Helper connHLP = new Helper(false);
connHLP.Retrieve("prcUpdateUsePoints", null);
}catch (Exception ex)
{
throw ex;
}
----------------------------------------------------------------------------------------------------------------------
Code for connection & retrive:
private SqlConnection conn;
private SqlTransaction tran;
public Helper(bool TransactionRequired)
{
try
{
string strConn = string.Empty;
strConn = System.Configuration.ConfigurationManager.AppSettings["ConnectionString"].ToString();
conn = new SqlConnection(strConn);
conn.Open();
if (TransactionRequired == true)
{
tran = conn.BeginTransaction();
}
else
{
tran = null;
}
}
catch (Exception ex)
{
throw ex;
}
}
public DataSet Retrieve(string ProcedureName, SqlParameter[] ParamCollection)
{
try
{
DataSet ds = new DataSet();SqlCommand cmd = new SqlCommand();
cmd.Connection = conn;
if (ParamCollection != null)
SetParameters(cmd, ParamCollection);
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = ProcedureName;
SqlDataAdapter adp = new SqlDataAdapter(cmd);
adp.Fill(ds);
return ds;
}
catch (Exception ex)
{
throw ex;
}
finally
{
conn.Close();
}
}
public void SetParameters(SqlCommand cmd, SqlParameter[] ParamCollection)
{
try
{
foreach (SqlParameter param in ParamCollection)
cmd.Parameters.Add(param);
}
catch (Exception ex)
{
throw ex;
}
}
----------------------------------------------------------------------------------------------------------------------
Thnking you all in advance.

The command object has a default timeout of 30 seconds. YOu will need to set this to some sort of timeout that is long enough for the stored procedure to run. If this is a really long running sp you may need to increase some of the web site timeouts as well.
Hope that helps.

Query Analyzer/Management Studio does not time out. In contrast, ADO.NET does have a default command timeout of 30 seconds. To change this, change the SqlCommand's CommandTimeout property.
You should consider investigating why this command is taking so long, however. Blocking an ASP.NET worker thread for any significant length of time seriously inhibits the scalability of your website.

Thanks for your reply.
Your answers could have solved my problem. If I limit the no. of users.
But that is the problem. No. of users will increase in coming time.
So if there is any other efficient way to solve this problem.
Plz tell me

Neither one of us suggested you needed to limit the number of user being returned. Both of us suggested that if you increase the timeout property of your command object then they will all return. If you look at the time in your query tool that it take to execute and it is like 1 minute, then increase your command timeout to like 2 minutes and you should be fine. If the time in it takes to execute is like 5 minutes then fix your query because you are missing indexes or something if it is taking that long to execute.

Hi all,
I have written a stored proc for searching in DB.For this purpose i have used ISNULL where in check whether the parameter is null or not.But when i use logical statement such as or in between sql statements it fails miserably.
for eg:
@skill1 varchar(50)=null,
@skill2 varchar(50)=null
select skill from JOBS
where
skill like '%'+ISNULL(@skill1,skill)+'%' or
skill like '%'+ISNULL(@skill2,skill)+'%'
here if i don`t enter skill2, @skill2 becomes null and hence the other part returns 1 and thus the query returns all data from table .
Pls help me for going about this
Thankx in Adv

I don't think you want to use isnull. I think what you are looking for:
where @skill is null or skill like '%'+@skill
Hope that helps.

Try and use Coalesce
Coalesce(@skill1,skill2,"")
|
|
|
|
|
As written, your query will return every row when either @skill1 or @skill2 is NULL because skill always matches skill throughout all rows.
Try something simpler like this:
((skill LIKE '%' + @skill1 + '%') OR
(skill LIKE '%' + @skill2 + '%'))
Concatination with a NULL value results in a NULL value. LIKE NULL will allways return NULL and therefore not qualify the row for inclusion. The OR will allow the other line to qualify or disqualify the row.
The added parenthesis are there for the OR. I have always had trouble with OR when I let the parser/compiler handle what is being OR'd.

hi,
i am getting an exception while inserting data into a ms access database in "da.Fill(ds);"
"No value given for one or more required parameters."
my code is like this
DataSet ds = new DataSet();
try
{
openconnection();
cmd = new OleDbCommand(query, con);
OleDbDataAdapter oda = new OleDbDataAdapter(query, con);
//fill the DataTable
oda.Fill(ds);
closeconnection();
return ds.Tables[0];
}
catch (Exception)
{
return ds.Tables[0];
}
finally
{
closeconnection();
}
thanks in advance

Dont you need to specify a table name in the oda.Fill(ds,"SomeTable")?

Firstly, you're attempting to fill a dataset with the results of a query, not insert data into a database with this code. Is that what you intended?
Secondly, the cmd object is not used. I don't know if you intended this. Passing the query string to the data adapter's constructor causes it to construct its own command object for its SelectCommand property. You can pass your own command object by using the version of the constructor that takes an OleDbCommand object.
I think the reason for the error is that the query string has one or more ? characters in it, indicating replaceable parameters, and you've not specified the values of those parameters. You'll need to use the command's Parameters collection for this.

I have an MS SQL Server 2005 database that uses data from another MS SQL Server database created by a third-party software company. Both are in the as instance.
I wish to create a stored procedure in my database to retrieve data from the third-party database.
The following code works fine :-
SELECT TOP (100) PERCENT NLNominalAccountID AS NominalAnalysisId, AccountNumber, AccountCostCentre AS CostCentre, AccountDepartment AS Department, AccountName<br />
FROM MMSv3_DemoData.dbo.NLNominalAccount<br />
ORDER BY AccountNumber, CostCentre, Department
The MMSv3_DemoData is the third-party database.
My problem is that I wish to my the database name an input parameter as have tried the following code :-
set ANSI_NULLS ON<br />
set QUOTED_IDENTIFIER ON<br />
go<br />
<br />
ALTER PROCEDURE [dbo].[spGetNominalAccounts]<br />
@Database AS VarChar(50)<br />
AS<br />
BEGIN<br />
SET NOCOUNT ON;<br />
SELECT TOP (100) PERCENT NLNominalAccountID AS NominalAnalysisId, AccountNumber, AccountCostCentre AS CostCentre, AccountDepartment AS Department, AccountName<br />
FROM [@Database].dbo.NLNominalAccount<br />
ORDER BY AccountNumber, CostCentre, Department;<br />
END<br />
What I get when executing the stored procedure is :-
Invalid object name '@Database.dbo.NLNominalAccount'.
Any help apprceiated.
Thanks

You have to build a T-SQL statement dynamically inside your stored procedure and then execute it using sp_executesql.
DECLARE @sql nvarchar(100)
SET @sql = 'SELECT * FROM ' + @Database + '.dbo.FOO'
EXEC sp_executesql @sql

The answer is always simple, when you know how.
Thanks alot, big help
