Delete Record From Table A that Is Not In Table B

Posted By:      Posted Date: August 29, 2010    Points: 0   Category :Sql Server
I have two tables; Table A id, name 101, jones 102, smith 103, williams 104, johnson 105, brown 106, green 107, anderson   Table B id, name, city, state 101, jones, des moine, Idaho 103, williams, Corvallis, Oregon 104, johnson, Grand Forks, North Dakota 105, brown, Phoenix, Arizona 107, anderson, New York, New York   I need to delete records from Table A that are not in Table B.  My front end is writen in .net and I am using Data Access Layer along with a Business Logic Layer for data interaction.   I have tried at least seven variations of joining, right outer join, left outer join resulting in wiping our the entire table or nothing at all; not to mention deleting the record that ought to remain and keeping the record that needs to be deleted!   In my BLL I tried to capture the rowsAffected for the deletion by using-without success. Dim rowsAffected As Integer = Adapter.ID_Deletion(ID) If rowsAffected = 1 Then Exit Function Else Return rowsAffected = 1 End If   Please help.   MsMe.

Delete one table record if the no more record are associated from another table

Hello All,   In my scenario I have two tables say Table A and Table B. Table A has 3 records   Id Name Value 1 ABC 123 2 XYZ 456 3 PQR 789   Now in another table I have 4 records   Id FName Lname TableAID 101 ABC XYZ 1 102 AAA BBB 1 103 XXX YYY 1 104 PPP QQQ 2   Now I display table B records in gridview when I select 3 records say id 101,102,103 and click on delete button. Table B selected records should be deleted and its working fine.   The problem is that in Table A record 1 ABC 123 is only associated with that many records so when I delete that record from Table B at that time the associated record in Table A should also be deleted as no more association with that record in Table B.   So please give me query or appropriate solution for that.

Update a record in a table?

HiI've been playing around with MVC lately, and was wondering how you could do this:I have a view that displays a list of products, and against each product is a list of categories (in a combobox). I'm trying to find out how you can update a product's category when you select a category in the list. I know you could do something fairly simple with jQuery, but I'm trying to understand how submitting forms works with MVC.Here's what I currently have:// Controller public ActionResult Index() { List<Product> products = _productRepository.GetProducts(); List<ProductCategory> categories = _productRepository.GetCategories(); ProductsViewModel viewModel = new ProductsViewModel { Products = products, ProductCategories = new SelectList(categories, "Id", "Description") }; return View(viewModel); } // ViewModel public class ProductsViewModel { public List<Product> Products { get; set; } public SelectList ProductCategories { get; set; } } // View <% using (Html.BeginForm()) { %> <table> <tr> <th>Id</th> <th>Description</th> <th>Category</th> </tr> <% foreach (var product in Model.Products) { %> <tr> <td><%: product.Id%></td> <td><%:

Possible to send an email if a record is added to a table?

I would like to be able to send an email notification if a website user inserts a new record in a table.  This will be a relatively rare occurrence so it would be very useful to have the notification as opposed to having my users check my summary page that lists all the IDs that have a record in this table. I googled but I must not be hitting on the right keywords or phrase to find the answer to this question. Thanks in advance for 1) letting me know if this is possible (I'm version ASP.NET 2.0 and using VB with a SQL Server database) and/or 2) pointing me in the right direction to find out how to do it if it is possible. Thanks!

InfoPath Forms : Adding rows dynamically from a SQL table along with a 'Delete' button per row


My requirement is something like this:

In a Task Approval form, I want to have a view which shows all the rows in a particular SQL table (in a infopath repeating table?). Along with each row, there should also be a button, on clicking which the row should disappear from the infopath view table. Do you think InfoPath can handle all this? :) 

To summarize:

1. How do I add rows to a table dynamically?

2. Per row, how do I create a button dynamically?

3. How do I remove the row from the view when the button is clicked?
