How should I set up a database to be able to efficiently maintain
associations between related items?
Example: Users shopping for Lord Of The Rings trilogy were also
interested in The Hobbit.
There will be many (20000+) items for sale and I need to do this
efficiently, but I don't have an idea how could I do it.
TIA
I'm trying to figure out how to associate users in my ASPNETDB.MDF to create a shopping cart.IE: I have 3 tables, for a list of existing orders, list of products, and list of specific orders.The idea is for users who've signed up with the built-in user creation control, can then place orders from the shopping cart, and view their existing previous orders. This would normally be done with a unique UserID # to associate orders with specific users, however I don't BELIEVE there's anything like UserID's associated with each user in the ASPNETDB.MDF, it just uses usernames as the unique identifiers right?Anyway I'm not sure I'm explaining what I'm trying to do perfectly and I apologize, but I don't think it's an un-common problem I'm having. Basically I'm trying to avoid having to have existing ASPNETDB users create a sort of SECOND user that would associate them into a seperate Customers table, it seems like extra user steps that shouldn't be necessary.

Good Afternoon
First time shopper on this board...hopefully you can help me.
I am trying to figure out how to schedule a DTS package located on a Server to run at a certain time. The DTS package will contain the path to a V/B 6 executable file residing on the same server.
So to test my methodology, I made a package on a server with code to run the V/B 6 executable off of my local machine. When executing the
package manually it works fine. However, when I schedule it the job does not start. I could not find a way to edit the job I had previously scheduled so I made another one in case I "fat fingered" something.
The same thing happens...no job starts.
Any ideas?
Thanks,
Ed

hi! I'm still fairly wet behind the ears when it comes to databases, especially sql server 2000. But I just got a copy from my University and I really want to spend some time messing with it. The first thing I want to try is making a shopping cart that stores the items in the database rather than in the session. I'm using asp.net (VB) and I had previously made a simple shopping cart for a SMALL site that stored all the information in a dataset stored in the session... but I've been told that isn't a good idea and reccomended I store the data in the sql database. so that's what I want to do!
I'm looking for resources that can help me get this started. These are the first questions I have about this approach, and any advice from you experts would be most appreciated!
1) do I store the data in a temporary table or do I use the regular table and make temporary rows? if the former how do I transfer the rows from the temp table to the order table? if the latter how do I change it from temporary to peromanent? in either case, how do I eliminate rows if the user abandons their cart?
2) how do I first initialize an order and keep track of the orderID for each user and ensure that no one is assigned a duplicate orderID?
those are my biggest confusions about this approach. I've looked for books on this but most are either too much about sql syntax and big-time server management, or they are too general and not specific to sql server. I've tried looking online, but I can't find much information on doing this using asp.net 2.0. thanks again for your help!

After a customer decides to buy a shopping list, there is generally aneed to store/insert one master record and a variable number of childdetail records, preferably all wrapped in a transaction. There are lotsof ways to do this and I am wondering if anyone knows which is mostefficient.One approach is to use ADO.NET's transaction capabilities, definesingle-record insert procs for the master and detail tables, and callthe detail insert in a loop from the web page. This has N+1 trips tothe server, which is not too attractive.Another approach is to concatenate all the data into a bigstring/varchar variable and pass it to a decoder proc that would thencall the single record insert procs via a loop inside the decoder proc.This second approach would use T-SQL's transaction capability and haveonly one trip to the server, but it is more effort to code on the webpage and in the decoder proc.Surely this is a common problem. Are there any more elegant/efficientmethods that anyone can suggest? Can one pass an array to a proc? Isthis a place for a user defined data type?Any advice is much appreciated.

Hello,
I'm in the progress of developing a shopping cart system that operates with an SQL database in Visual Web Developer 2005. I've managed to successfully add items to the cart and display them, but I'm having trouble providing the user with the option of removing items from the cart.
My understanding so far is that I've got to adjust the DELETE SQL statement of the data source. At first I was thinking along the lines of a simple statement:
DELETE * FROM ShoppingCart WHERE CartID=@CartID AND CategoryID=@CategoryID AND ProductID=@ProductID
However, I've realised that the parameters I need for this SQL query aren't automatically passed in when a user clicks the "Delete" text of the Delete field (at least I think this is the problem).
The error message which I'm getting when I try to remove an item from the cart is as follows:
Incorrect syntax near '*'.
If anyone could let me know where I'm going wrong and point me in the right direction I'd be really grateful.
Thank you,
Luke
Dear all,
I am trying to create a recipe database and one of the funtions is to generate shopping list based on the selected recipes.
at the moment, I have a table --recipe, a table--ingredient, and a cross
over table between these two, reIng.
Does anyone know how can I write a procedure with cursor that no matter how
many recipes the user selected, a list of ingredients will be created based
on that? Another things I can't solve is if an ingredient appears twice, how can I make them sum together..
I can write a simple procedure with one parameter so that I can get the ingredients for a certain recipe.( the parameter is the recipeID ). But I get struck when the possibility is that user will select more than one recipe and
wish to get a list of the ingredients. should I use a cursor to do that? Or I should create a temporary table to store the selected recipe?
THanks for your help!

We have an existing SSRS server, and have just created a new child domain. We'll be migrating users from the parent to the child, and want to add the users of that new domain with access to SSRS. In the parent domain they are able to access, but after migration with the child domain account, they cannot.
I have added the group CHILDDomain Users with a system user role on SSRS, and PARENTDomain Users was already there.
Is there any additional step I should/could take to get this active?
I have had this issue just pop up. I have local users who can connect fine, but my users that require connection by VPN cannot connect. I get the server not available or access denied error.

I am having a problem understanding the db users.
I am working on a DNN site, and having troubles with db users permissions.

1- Login with the public user, create tables, views, sp, add data ...
2- Use the dbo always?
In my application, I will be using the public user in the connections string.

I need to get a copy of the users table from the master DB to another machine I have.
This is to include permissions / passwords etc
anyway this can be done? Cheers!
I'm using SQL 2000 and I'm the database owner. I have been running tests with stored procedures to add logins, revoke logins, add db access, revoke db access etc.
Now I can't seem to add users to the database. I've tried using 'dbo' and 'domainmy_username' but I'm denied permission to run any stored procedures to try and add myself to the db_accessadmin or sysadmin roles.
I've tried the New Database User dialog and choose <new> under login name. I browse for the user name on my domain, click OK, and I get the message 'You must be logged in as 'sa' or a member of sysadmin or securityadmin to perform this operation.'
I thought the dbo always had full permissions on his database. This doesn't make sense to me. :confused:
The only thing I can figure is my permissions have been revoked on the master db.
Can anyone help?

Hello,
I am new to this forum, and ASP .NET 2.0. I watched the tutorial on how to use the login control with SQL Server 2005 Express, and was able to duplicate it easily. However, I tried to see if I could do the same thing with SQL Server 2005 that is hosted by my hosting company, and I was unable to get it to work. I am using Visual Web Developer 2005 Express, at least until I get VS 2005 in a few weeks, and I am able to connect to the SQL Server. I tried following the tutorial on this site step by step, and some of the things they used to set it up I could not use. In the tutorial VWD creates the table automatically. If I use the hosted database, do I need to create the table, or is there a way for VWD to do it that I haven't figured out yet.
Any help and additional information that I might need to know would be great.
Thank you for your help.

I recently moved my .NET project out to production, the server is Windows 2003 running SQL 2005. My developement server was a Windows XP running SQL 2005. Here is my issue.
Under development I created a specific user to log in as, created a role and specified exactly what application specific stored procedures etc. that user was allowed access to. Everything worked fine. Backing that database up and restoring it to the new server, when I attempt to log in as the user (and yes I re-created the login, with the user, just as I did on the development server), I get this error...
EXECUTE permission denied on object 'aspnet_CheckSchemaVersion', database 'MoldKit', schema 'dbo'.
So I attempt to login as SA, and everything works... so I assign the db_owner role to my user and login, everything works... problem being they shouldn't be db_owner. And they're most definitely not assigned this role on development. I even went so far as to delete the database, and recreate it from scratch using the aspnet_regsql.exe and I get the same error. Anyone have any idea why this is happening, or the proper roles I need to assign so the user isn't a dbo, but can still call all the required aspnet procedures. Or could this be some other issue caused by 2003?
I've seen this error in a lot of posts, but never once saw a definiative answer to what causes it and and what the fix is.
Hi there,
When conecting to a MS SQL Server 2005, I could define in my connection string Windows Authentication.
What account it will be used? The one used by IIS (I still don't know the user ASP.net runs, if it is independent of IIS or not)?
And if I whant that some aspx pages have diferente acess rights? I need to use SQL Server Authentication with diferent users created in MS SQL Server right?
In ASP.net, what is best practice: Have one SQL account, and make users access rights in Business Logic, or have different SQL Accounts por the diferent access rights I whant in every page?
Sorry if this are basic questions, but In the find's I made, I saw very confusion ideas.
Thanks in advance, and sorry my english.
