C# - Best Practice For Inserting/updating Data In Multiple Tables At Once?

Feb 11, 2011

So I have two tables in my database, Contacts and Addresses:

Contacts : ContactID | AddressID | FirstName | LastName

Addresses: AddressID | Address1 | Address2 | City | State | Zipcode

I have a page where you can add a contact. It contains all the information for a contact and an address for a contact. Here's my code for when you submit the form:

[code]...

Now my main concern is that the address is added successfully, but then an error occurs when I try to save the contact, leaving the address in the database with no contact.

What's the best practice here for rolling back any changes if an error occurs?

Databases :: Importing - Updating Sql Tables From Excel Sheet Into Multiple Tables Daily

Jan 4, 2011

I have an C# ASP application I am writing that needs to have the capability to import a generated excel or a comma delineated sheet each day. A clerk will have this job each morning so it doesn't need to be automated. My problem in trying to understand the solution to this is that the 1 sheet contains loan information, including customer information all in the same sheet. I would like to send certain columns to update information in the loan table and send other information to update the customer table. I need it to create relationships when new loans appear in the spreadsheet.

Web Forms :: Inserting Into Multiple Tables Code Behind

May 8, 2010

I have to code this:

I'm building a registration page. The form will insert into multiple table at the same time. I need to automatically get the data from one of those tables and insert it in a field into another 2 tables.

Tables:

[URL]

As can be seen both the tcoach_Members and tcoach_Roles table have a column named UsersToRolesId; this column is a foreign key to the UsersToRoles table.

In the UsersToRoles table the Id "Is Identity" and increments by 1 automatically. The UserName and the RoleName will be entered into this table upon registration of a user. Following this, in the Roles and Members tables, this Id number must be entered.

The question is, how can I grab this Id number from the UsersToRole table and insert it into both the Roles and Members tables, via code behind? Can anyone advise me of a way to do this?

The code below is what I've done so far but I am stuck at this Id number:

SQL Server :: Updating Multiple Tables Simultaneously

Sep 8, 2010

Was wondering if someone can help me out with this multi update problem

I have a webform that populates a single table but due to certain dropdown data conditions it could also potentially populate 3 other tables

The tables information populates a gridview with amounts from accounts etc..

e.g.

Table 1

Site DataType account update

34 SS 12.50 N

Table 2

Site account

34 12.50

Say the above entry has the updated column changed to Y via the webform the amount 12.50 should disappear from the gridview. I was

a bit shortsighted and added the additional tables afterward. The information on the gridview pulls from the additional tables and since

the first table and the additional tables are not linked the data still stays the same in the gridview

I do have an Id column on both tables but unfortunately I added the rest of the tables after the first one so the Id's do not really match.

Forms Data Controls :: How To Stop A Detailsview From Inserting Or Updating

Aug 12, 2010

Here is the scenerio:I have a radtabstrip (with 2 tabs) at the top of my page followed by radMultiPage control Tab 1 displays pageview 1 which has a gridview showing data from our database and allows for selection or deletion of data tab 2 displays a detailsview when gridview_selectedindexchanged(from tab 1) is fired.Problem... If you select an entry in the gridview it switech the page and the detailsview into editmode (works fine) but if you then click on tab 1 without clicking update or cancel in the detailsview, the data is updated. This is what i don't want as the user has basically abandoned the changes.So what i need is a what to say ... if the detailsview is in edit or insert when the tabstrip is clicked then cancel the insert or update. I tried switching it back to readonly mode but that did not seem to work.

Forms Data Controls :: Inserting / Updating Sql Data From A Listbox In Formview?

Jun 2, 2010

I have a web page with a gridview & formview (master/detail relationship) combo. On page load the gridview shows all records from a SQL table. On my page I have a button that when clicked shows the formview in Insert mode to allow users to add a new record to the data. I have also added a column to my gridview that has a link. When a user clicks this link it hides the gridview and shows the formview in edit mode with the detail from the record selected from the gridview.

In my formview I am using a listbox control to allow users to select multiple values. The choices in the listbox are populated by a SQL data table. I have successfully written code to post the selected listbox values to my SQL data field during Insert. When the user selects a record to edit I have code in the databound event to select values in the listbox from the choices based on the value in the sql data field. This works as well. My problem is that I cannot figure out the correct code to update my SqL data when a user is editing the record and makes changes to the selected listbox value. I have included my design code for my listbox in my formview edittemplate and also my behind code that I have attempted.

<td
style="width: 454px">
<asp:ListBox
ID="lbox_ConstructionType"
runat="server"
DataSourceID="SqlDataConstructionTypes"
DataTextField="Construction_Type"
DataValueField="Construction_Type"
SelectionMode="Multiple"
Width="144px"></asp:ListBox>
<asp:TextBox
ID="tbox_Ctype"
runat="server"
Text='<%# Bind("ConstructionTypeID") %>'></asp:TextBox></td>

DataSource Controls :: Sql Server Deadlock / Only Inserting/updating Data Into A Table

Jun 11, 2010

I m getting following error in my eventvwr . I couldnt find reasons of the following error.

"Transaction (Process ID 110) was deadlocked on lock | communication buffer resources with another process and has been chosen as the deadlock victim. Rerun the transaction. "

The only thing my page is doing is inserting/updating data into a table in sql and the thing I can think of is because multiple users are using the same page to insert/update data? Will that cause deadlock?

SQL Server :: Inserting Same Autonumber To Both Tables?

Sep 10, 2010

I have an SQL DB which contains 2 tables. The first one 'advs' has some information about an advertisement and it got an ID field. The second one, "photos", contains all the paths of photos, this one also has an ID field.

Each advertisement from the 'advs' Table has three photos in the PHOTOS table. now obviously the photos related to the 'ad' must have the same ID.

What I'm trying to do is a Form to add the information about each advertisement and its' photos. This form should enter the SAME ID number to both tables AUTOMATICALLY after adding.
