You can do this with DTS - however I would advise just writing a stored procedure or an adhoc script to do a select from one table to insert into the other.
The reason I mention this is that DTS packages with all their VBScripting etc can hide a lot of their functionality.
From a maintenance point of view this can sometimes make it very difficult to see what is going on.
One more issue is this - SQL Server 2000 DTS packages don't like temporary tables in their data pumps(I don't know about 2005), you can use them but you have to be wily in how you use them.
You always pass failure on the way to success.

Records in the table are physically sorted in the order of the Primary key Column by default. You can't update the order of the records programmatically.

Actually they are physically sorted in the order of the clustered index information - that's what 'clustered index' means. However, it is the default to build the index supporting the primary key as the clustered index. Tables without a clustered index are not sorted and are referred to as 'heaps'. Specific rows in a heap are referred to internally using row identifiers which give the physical location of the row, but this information isn't available to clients.
If you wish to update a specific row, you need to include some kind of row identifier within the table such that each row has its own identifier.
SQL Server 2005 does provide the RANK function which might prove helpful for updating an ad-hoc query.

If you run your DB Scripts on a SS2005 DB, or import your existing DB into it, odds are high it will just work.

If you want to process data row by row then you will need to use cursors but generally they are slower then set based solution so you should avoid them
|

|

Posting more details can help us helping you,
Do you have these records in local or temp table?
Why do you want to access them sequentially?

Hi.
For the last 14 days i have been struggling with design pattern (T-SQL / Tables) for cascading product variants in a E-Commerce solution ("value-pairs pattern" / "diamond pattern"). I did find this DB diagram from IBM (http://publib.boulder.ibm.com/infocenter/wchelp/v5r5/topic/com.ibm.commerce.developer.doc/refs/rdmattribute.htm), which seams to be a good table design.
My problem is, that i cant figure out how, to make the SELECT statement for each cascading selection. Attributes should be selected in a specified order, each dropdown below is disabled until the previous selection is made.
Table design is like this:
"Product"
"ProductAttribute" (Relates each combination (T-Shirt, Small & Red) to a ProductID ..... AttributeID > ProductID)
"Attribute" (Relates "AttributeType" and "AttributeValue" together)
"AttributeType" (Type, Size, Color)
"AttributeValue" (T-Shirt, Jeans, Jacket, Small etc)
If i have 3 drop downs, with the following options:
Dropdown #1 (Type): T-Shirt, Jeans, Jacket
Dropdown #2 (Size): Small, Medium, Large, Extra Large etc.
Dropdown #3 (Color): Red, Green, Blue, Purple etc.
When the user selects a Type, Dropdown #2 is enabled and populates with possible values for Size. The problem is, how to make a T-SQL that only selects the available sized with the type "T-Shirt".
There is not limitation on how many Attribute each product can have. So a product could have X amount to attribute selections (dropdowns).
Thanks in advance

A SELECT statement that utilizes a number of correlated subqueries should solve your problem.
Something like:
SELECT DISTINCT AttributeType, AttributeValueID
FROM Attribute
INNER JOIN AttributeType
ON Attribute.AttributeTypeID = AttributeType.AttributeTypeID
WHERE AttributeType.AttributeType = 'Size'
AND EXISTS
(
SELECT TOP 1 *
FROM ProductAttribute
WHERE AttributeID = Attribute.AttributeID
AND EXISTS
(
SELECT TOP 1 *
FROM ProductAttribute AS ProductAttribute1
INNER JOIN Attribute
ON ProductAttribute1.AttributeID = Attribute.AttributeID
INNER JOIN AttributeValue
ON Attribute.AttributeValueID = AttributeValue.AttributeValueID
WHERE ProductAttribute1.ProductID = ProductAttribute.ProductID
AND AttributeValue.AttributeValue = 'T-Shirt'
)
)
Hope this helps

In SQL Server 2005 you can do it as following
1. Right click on Connected server.
2. Select Properties menu.
3. Select "Security" option from left pane.
4. check the "Server authentication" option in right pane.
5. Select "Permissions" option from left pane.
6. Add Login or Role to particular user.
Knock out 't' from can't,
You can if you think you can

Thanks for your answer , But :
I'm in a workgroup environment , In this situation , How can I add users of other client computers that are going to connect to server?
and another point is that when I finished writing the program , What settings should I change in order to make my program available for client computers?
Thanks in advance .

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.
