I am attempting to insert into two tables at once, but it's inserting blank values into the first table, and then correctly inserting the values into the second table. here is my codebehind, I can post the rest of my code if needed.
[code]...
Even when I comment out the second insert command, the first one still inserts null values.
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.
I have a view which displays columns from multiple tables. for ex memberprofile(firstname, gender )
membereducation( education), memberoccupation(occupation) etc.
now i want to insert them. how to make this view strongly typed with multiple tables iam using linq.
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:

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?
I have an excel sheet with 2 tabs and has data in those 2 sheets(sheet1, sheet2) which correspond to different tables in the same database. This excel sheet gets updated daily, I am wiriting a console app( which will later be a batch build). I have to insert the data from the excel sheet to corresponding tables (table1, table2,table3) in database when i run it and and also if the table has the same data already present it should ignore and if there are any modifications done the data it should update the table. I know we can do this using ado.net or LINQ, I am a little new to database based programming .

View 3 RepliesI have a webpage with a gridview on it which is bound to a table in an Access database. So I now drop a dropdownlist on the webpage and when the Choose a Data Source popup appears if I select my Access data source there is nothing in the select a data field for display and select a data field for value fields on this popup. So it appears I have to create another Access data source. But why if I already have an Access data source on the same database? What am I doing wrong?
View 7 RepliesWhen I add an AccessDataSource and attempt to configure it, the "Advanced SQL Generation Options" panel opens, but checkboxes "Generate INSERT, UPDATE and DELETE statements" and "Use optimistic concurrency" are sometimes grayed out.It appears that this happens when a table is specified that contains a foreign key, and it also seems that any Update query statement I specify in conjunction with a related databound gridview doesn't "take". What's the story here? Is it not possible to update a database table from a databound gridview control if the underlying table has a foreign key? Or is something else going on?
View 2 RepliesI wish you are having a wonderful day Today I encounter a problem which I am unable to solver yet. have a e-mail subscription area and I am using accessdatasource for that. Also I am inserting the e-mail adress into database with AccessDataSource InsertCommand in aspx page not in codebehind. What I want is that;I want it to first check for the textbox-email value if it exists already or not ! Then if exists, I want to make "LabelOutPut.Text = "Already Exists !"" But if not exists, I want to do on button click that; "AccessDataSource1.Insert() and LabelOutPut.Text = "Subscribed !"

I'm using an access database that has an AutoNumber field as the primary key. After adding a record I'd like to retrieve the ID for the record that was just entered, however, I'm not able to figure out how to do this in ASP.NET using standard AccesDataSource and FormView functionality. My goal is to retrieve the ID so that I can then use it to add an additional record in a child / sub table.
I could do it strictly using vb.net and forget about using the InsertCommand for the AccessDataSource and it's built in functionality. However, that would require a complete rewrite of some other items, accomplish this using the standard AccesDataSource functionality.
Below is a sample of something I've tried to do using "Direction='Output'" on one of the ID field for one of Insert paramaters (source: http://www.4guysfromrolla.com/articles/050207-1.aspx). The plan was to then caputre that "output" using the my "_OnInserted" sub procedue. However, apparantly I'm not able to use this with AccessDataSource. Did some research and saw that I'd have to switch to SqlDataSource which I'd rather not do cause all other pages use AccessDataSource and I'm having problems defining my connection string with it.

View 1 RepliesI'm trying to display all orders placed and I have a primary accessdatasource control that has a select query to get the customer information and the orderID. I want to use the orderID value from this first query as a parameter for the secondary accessdatasource control that selects the product information of the products in the order. In plain english, I want to:- select product info from product table where orderID = ?(where ? is the orderID value from the first query)
I have tried the <%#Eval("OrderID")%> but I get a "server tag not well formed" error, but I do get results returned when I just type the order ID in, but obviously every result (order) just contains the same product info...

How do I assign database to AccessDataSource control dynamically.
If I load aspx page by mypage.aspx?DB=100 then I want to use 100.mdb as data base
If I load aspx page by mypage.aspx?DB=200 then I want to use 200.mdb as data base
Both databases are identical except for the fact that data is different.
Here's default code - Need to replace Bold Code with equivalent of DataFile = response.querystring("DB") + ".mdb"
<asp:AccessDataSource ID="AccessDataSource1" runat="server"
DataFile="c: rims2k�00001000.mdb"

View 1 RepliesI 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.
