SQL Server :: Updating Multiple Tables Simultaneously
Sep 8, 2010Was 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.

View 4 RepliesDataSource Controls :: Display Results From Two Separate Tables In Two Separate Databases?
Jan 14, 2010I have access to two seperate databases (mySQL) located on two servers. I need to get the data, link the tables on a key field and display the results in a datagrid. My challenge is that if the search criteria changes for the display it affects rows returned from on table and should thus automatically affect the linked table and resulting data returned.
what the best approach would be to achieving this? So far I have set up a dataset with a dataadapter and table for each connection and then linked the tables in the dataset. The problem that I'm having is getting the linked resultsets to work.
On my form I have the datagrid with two Objectdatasources one for each dataadapter and i believe that's where I'm going wrong...
SQL Server :: Use ASPNETDB.MDF To Add Own Tables Or Create A Separate Database?
Dec 6, 2010I'm working on a new asp.net 4.0 resume web site. I'm starting off with SQL Server Express 2005 and using the standard security and login features given with ASPNETDB.mdf. My site will be hosted on GoDaddy.com.
Quesiton. Should the tables that will contain the information that users will be putting in like resumes, contact information and such go into ASPNETDB.mdf or should it go into a separate database.
SQL Server :: Database Design / Create A Separate Table Which Will Contain The Translations For All 50 Tables?
Sep 28, 2010I am working on a multi-lingual application Assume the following:
Database has 50 tables and application has to support 5 languages
Which is the best way to design the database:
1. Include a langugae column for each table. Repeat the values for each language. Say i have a country table which has 100 countries in it. Then my design will contain 500 rows (100 for each langugae)
2. Create a separate table which will contain the translations for all the 50 tables in with a foreign key to the parent table.
Which is more efficient out of the above two.

MVC :: Create Two Objects On Separate Tables Using One POST?
Jan 13, 2010I'm trying to achieve something very similar to a forum. Two basic tables in a database, [Thread] and [Comment] (one to many relationship).
I need to create a form using MVC that creates the initial Thread, and also the very first comment row in the [Comment] table, which references that topic.
Would I need to create a custom object for the View Model? Is there any examples anybody knows of that demonstrate what i'm trying to achieve as I can't seem to find information..
SQL Server :: Simultaneously Connecting To Db With VS, Website And SSMS
Aug 27, 2010I have recently combined my aspnet membership database and main website database into one database file, I'm happy with the schemas, stored procedures etc. (This is a development project not yet a production project.)
My problem is that I can no longer simultaneously connect to the database from Visual Studio if a user is logged in to the website.
EG:
Scenario 1: No user is logged in to the website. I can go to the Data Connection window in VS, choose "Add Connection" and then inspect the contents and schemas of the database. This is fine.
Scenario 2: A user is logged in on the website. I try to connect to the website in VS and get the error:
"Cannot open user default database. Login failed. "
Scenario 3: I am connected to the database in VS and nobody is logged into the website. If someone tries to log into the website they get the following error:
Cannot open user default database. Login failed.
Login failed for user 'NT AUTHORITYNETWORK SERVICE'.
So it seems from the above that there can be only one connection to the database at a time? However this was not the case before I combined the membership database with the main website database. I could always make changes as a user logged into the website and at the same time see those changes through the connection in Visual Studio.

SQL Server :: Separate Web & Database?
Nov 4, 2010Currently, we have our ASP.NET applications running on windows server 2003. All of our data resides on an IBM ISeries / AS400. The 400 people are going to be creating massive new tables with millions of records. Because of this, I've been asked to look into the idea of putting new ASP.NET pages on the IBM ISeries server. This server uses APACHE. I have read that to do this, I will need to use the Mod_Mono Apache module. I would like to come up with a list of benefits and drawbacks to this new idea. Initially, it seems like this is a bad idea for a few reasons:
Security: if a users gets unauthorized access to our local server(s), they will only have access to either DB or web server, not both. Maintainability: Microsoft ASP.NET is easier to implement on a Microsoft Windows Server. Problem Solving: I will have to first determine if an issue is due to the ISeries server, or the Apache server, or the ASP.NET application. This could be countered by saying that I would already have to determine if the issue is due to Windows server, or ASP.NET application. However I have better experience with troubleshooting on a windows box that I am familiar with.
Problem Creating: I could escentially create a problem that not only takes down the web server, but the database as well, and other RPG programs running on the ISeries. Resources: The database server will not have to server my application, it will only have to retrieve the data for it.
Drivers: The windows server already contains many drivers and .DLL's that are used... will these even exist on the ISeries? How easy (if even possible) would it be to get them on the ISeries if they dont exist..? A few positive thoughts: The application will reside on the same server as the data, thus, it may be quicker at retrieving data from these millions of records in a table. This was the main point as to why I should look into this possibility. Single point of failure. We no longer have to worry about two servers going down and causing this application to be unavailable...
