Im making a shopping cart website for a school project in ASP.net with VB. I need help subtracting the quantity purchased (its saved in a session) from the stock number saved in a database.I know this:UPDATE inventory SET stock = stock - <quantity_purchased> WHERE id = <inventory_id>But I dont understand how to get the quantity purchased from the session to <quantity_purchased>. I tried putting the name of the session there and I got an error, i tried saving the session into a dim didnt work either.

Wanted: Sql Shopping Cart Resources

Sep 30, 2005

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!

Adding A Delete Functionality To My Shopping Cart

Dec 29, 2005

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

Connecting Users From ASPNETDB.MDF To A Shopping Cart And Order History

Jan 2, 2007

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.

Sequence Numbering Items In A Cart

Dec 15, 2005

I'm looking for any help/tricks on creating an item numbering system in a MSSQL database. The object is to number the items in a cart from 1 to whatever and have the ability for the user to change that sequence. The client wants the ability to order the items any way they choose by changing the sequence number. This process would require.
1. Starting at one (1) for the first item in the cart and incrementing from there.2. If I have 10 items and I change item 3 to 5,  items 4 and 5 have to increment down by one and 6-10 would stay the same. (and vise versa moving item 3 to item 1)3. If I have 10 items and I delete item 4, 5-10 must incremet down by one.
On 1 my first though in adding items is doing a select count to see if any items exist in the cart. If they don't assign the number one. if it does do a max on the sequence column and increment by one.
on 3 I would simply delete the item and do an update on all items with seq# > then the deleted Seq#
on 2 I'm not sure yet.
Am I on the right track and are there any tricks to doing this? Any help would be appreciated. This would all be done in stored procedures.

Shopping For DTS Package Scheduling Help

Mar 3, 2004

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

What Is The Best Way To Store A Shopping List Or Order?

Oct 17, 2006

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.

Get Shopping List Based On Selected Recipes

Nov 19, 2007

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!

Database Empty

Mar 23, 2006

hello everyone,
am not sure if this is the right forum, but here goes.

We have a couple of clients we support running MS SQL, and as a rule, all db access is by SP and select statements.

However, we noticed earlier today, that a newly created account was empty. All columns except the users columns had been deleted.

1. Is there a way of checking which user account deleted the columns ?
2. Or finding out what went wrong ?

This has never happened before

Does SSRS Have To Create Its Own Database? Or Can It Use An Existing Empty One?

Sep 10, 2007

Hello everyone,


Greetings! I just found this group after wasting hours trying to make
SSRS work with databases that are already created (that is, the DBA
created two empty databases for me, X and XTempDB).



I keep getting "this connection string is invalid can't use this to
connect to SQL Server" in the Database Setup tab.



The problem is that to create its own database, SSRS needs dbcreator
and securityadmin roles (please correct me if I'm wrong here). And I'm
having a helluva problem trying to convince the DBA to give me
temporary dbcreator and securityadmin roles!

Is there any document or
something that I can use to convince him that SSRS will not do
anything like recreating the login (because he said that the login has
already existed and has its role set up in many other databases)?


Any help, pointers, suggestions, etc. is very much appreciated.



Thanks,
Ray

Database Insert Question - Best Practices For Empty Data

Apr 17, 2007

I am making a form that takes input for 1 to 5 students using VWD.  With the help of previous posts I have been able to make the database insert query work properly.  In my form I have a radio list that has the user select if they are entering information for 1, 2, 3,4, or 5 children.  Depending on how many children are selected on the radio list, I am displaying the proper number of textboxes and validating the data using the handy RequiredFieldValidator.  Now I am at the point where I want to perform the instert to the database depending on the selected number of children in the family.  What is the general rule for best  practices. Please keep in mind that it is my understanding that ALL fileds in a SQL insert statment must have data. Should I ...1) create alternative SQL statements depending on the textboxes displayed OR2) is it more common to insert a standard string or integer, depending on the datatype, into the unused textboxes to populate the unused fields? Sincerely,Mike

Impact Of Empty Tables On Database Size And Performance

Jun 21, 2007

Hello All,

When creating my database I have modeled some of the tables after the Adventureworks sample database.

There are some fields or entire tables in Adventureworks that I do not see an imediate use for, however; I would hate to ommit them to find out later they would have been benificial. (.eg territory table).



In general terms what would the impact be on size and performance of a database which contains tables or fields that do not contain data.

A Curious Error Message, Local Temp Vs. Global Temp Tables?!?!?

Nov 17, 2004

Hi all,

Looking at BOL for temp tables help, I discover that a local temp table (I want to only have life within my stored proc) SHOULD be visible to all (child) stored procs called by the papa stored proc.

However, the following code works just peachy when I use a GLOBAL temp table (i.e., ##MyTempTbl) but fails when I use a local temp table (i.e., #MyTempTable). Through trial and error, and careful weeding efforts, I know that the error I get on the local version is coming from the xp_sendmail call. The error I get is: ODBC error 208 (42S02) Invalid object name '#MyTempTbl'.

Here is the code that works:SET NOCOUNT ON

CREATE TABLE ##MyTempTbl (SeqNo int identity, MyWords varchar(1000))
INSERT ##MyTempTbl values ('Put your long message here.')
INSERT ##MyTempTbl values ('Put your second long message here.')
INSERT ##MyTempTbl values ('put your really, really LONG message (yeah, every guy says his message is the longest...whatever!')
DECLARE @cmd varchar(256)
DECLARE @LargestEventSize int
DECLARE @Width int, @Msg varchar(128)
SELECT @LargestEventSize = Max(Len(MyWords))
FROM ##MyTempTbl

SET @cmd = 'SELECT Cast(MyWords AS varchar(' +
CONVERT(varchar(5), @LargestEventSize) +
')) FROM ##MyTempTbl order by SeqNo'
SET @Width = @LargestEventSize + 1
SET @Msg = 'Here is the junk you asked about' + CHAR(13) + '----------------------------'
EXECUTE Master.dbo.xp_sendmail
'YoMama@WhoKnows.com',
@query = @cmd,
@no_header= 'TRUE',
@width = @Width,
@dbuse = 'MyDB',
@subject='none of your darn business',
@message= @Msg
DROP TABLE ##MyTempTbl

The only thing I change to make it fail is the table name, change it from ##MyTempTbl to #MyTempTbl, and it dashes the email hopes of the stored procedure upon the jagged rocks of electronic despair.

Any insight anyone? Or is BOL just full of...well..."stuff"?
