Now I'm developing web application with ASP.Net MVC but I have to use 3 databases. So I have no idea about this. I have to extract the data from 2 databases and I have to save the data to another 3rd database.
View 7 RepliesI have a situation where I am accessing a database multiple times and I'm wondering if it is necessary.
I have a GridView with a template column with a hyperlink to "Get Results" and on the RowDataBound event I have it check the batch number against the database and see if results exist and then if they don't, hide the link.
So when viewing the page if there is 20 rows in the gridview it is effectively doing 20 queries.
I was wondering if it is a better idea to query the database once with all "batches" and load it into a datatable, then on the RowDataBound event query the datatable. The only issue I see with this is there is currently 40,000 batches and grows daily.
How can i connect my local project with the SQL server 2008 Database that is running on other server (This server is not on my network and i connect to it via remote desktop connection).
View 1 Replies If I have the appropriate permission, is their a way to access a sql server database on two different servers?
For example if I have a Table A on server 1 and Table B on a different server. How would I join the two tables together, if they each have a column named "PonyId"
I have never tried Cross Tab query in sql server. Googled but could not find possible solution.

I am creating an insert statement in my c# code to insert records to an access database table. I am getting the error copied below using c# code. When I copy the generated insert statement from the console and run this on my access database, it succesfully appends a record in the table.Insert statement generated:
insert into [Pet Fish-log 2010] ([Specimen Type], Year, [Lab Number], [Last Name], [First Name], [Middle Initial], Gender, [Date of Birth], [Collection Date], [Date Received], Client, [Tissue Type], [Block Number],

I am using SQL SERVER 2008.
Now I want to access the SQL SERVER 2008 DATABASE on the LAN.
So what was the Connection String and can u give me the Example of that.
I am pulling a date from an Access Database and inserting into my Dataset. I am assigning it to "myDate" and then assigning it to my SQL parameter @StartDate.
When I run my ExecuteNonQuery I get a null value in my SQL database. There are no null values in my access database. I must have the syntax wrong.

In the development environment, in SSMSE > MyDatabase > Security > MyUser > Database role membership I have checked db_owner to allow me to build the database.
Now I am copying the database to the production environment I would like to lock the security down tightly. In the past (with classic ASP applications) I have only checked db_datawriter and db_datareader and, in Securables, checked Execute Grant on the stored procedures.
In Database > Securables I add my stored procedures and check Execute/Grant for each of them and click OK. When I return to the securables page the stored procedures are no longer listed.
I have noticed that nothing is listed in Effective Permissions and I think it should list Execute. If this is the problem, how do I add Execute to the Effective Permissions list?
I have a requirement where i need to combine tables from two different datacontext. Does Cross context is allowed in Linq??
i wrote a linq query but its throwing error.
I have some structured objects that map to multiple DB tables that I have created using LINQ using [Association(Name=, Storage=, ThisKey=, OtherKey=)] links to the objects attached to other tables. If I try to create an association to an object attached to a table on another database server, will this throw an error/go horribly wrong (I'm guessing yes)? If this _is_ possible, are there any issues I need to be aware of?
View 2 RepliesIn remote db, I can be able to connect ms sql db as localhost in my connection string like below,
<
add
name="ConnectionString"
connectionString="Data
Source=localhost;Initial Catalog=DBServer;Persist Security Info=True;User ID=sa;Password=*****"
providerName="System.Data.SqlClient"
/>
This is running in server and its working fine.
If i want to make any changes in db structure or need to modify any data values, i have to login remotely to my server and has to open sql server management studio do db change or value editing stuffs. Its really getting iritating when the remote machine looks slow.
I just want to know how to configure the db hostname like dbname.domainname.com or mssql.domainname.com in server, so that we can open the server db in local using sql server management studio.

I have a lot of members data to enter into the ASPNETDB database. How can I read this data from an Access data file and input into the SQL database. All data is for user Names and Password,
View 1 RepliesI am using an SQL Express server hosted on a different machine and it is listed in my server explorer just fine. It is listed as my connection string in my web.config just fine as well and lastly it seems to sync just fine with my asp.net membership tables. My question is does it need to be listed in my app data folder of my site? Currently I have the ASPNETDB.mdf connection listed, which is apparently just a local sql express connection. The database I am using in my webconfig and other files is not listed so do I need to add it there?
Second question is about DAL, Data Access Layers. I have mostly been using presentation level SQL commands with my data presentation controls. Manually entering separate select, insert and update statements. I just went through a tutorial that stated the best way to interact with your database in asp.net is with DAL using table adapters. It mentioned that it gives you the ability to use strongly-typed references to each row. My question is can I use the same method multiple times on a single page. For instance a method inside an adapter named GetProductsByID(@ID) ? What if I want this bound to three different gridviews on a single page? Anyone have any other general things to point out about using DAL over presentation level commands?
does anybody knows if EF 4.0 supports cross database joins for its entities?

I am storing a custom "Organisation" object as a session variable. One of the properties of the Organisation object is "OrganisationID" (integer). I have a DataSource that requires a parameter value to run, and I want to use a SessionParameter to populate this. In a previous version, I stored the OrganisationID directly as a session variable. In that case, I could easily access it like this:
[Code]....
However, how do I now access the OrganisationID property of an "Organisation" type session variable (called "Organisation")? I have tried this, which does not seem to work: <asp:SessionParameter Name="OrganisationID" SessionField="Organisation.OrganisationID" Type="Int32" />
Is there anything missing in IIS 6.0 that prevents me from (Insert into table) using MS-Access?
Explain: The application works fine under Visual Studio 2008 IDE the insert into table works fine with no error, Also I tested with hosting provider and works fine with no problem. but now I have published the same exact app in a dedicated server windows 2003 with
IIS 6.0 .NET framework 2.0 with latest service pack I gave IIS_WPG write/modify access to the folder where MS-Access database is located and database but at the time of insert an error pop-up. I need to install in the Server or settings in the IIS to recognize my MS-Access db is it some office runtime that I am missing. (BTW I am using OLEDB connection string in my C# )
Using System.Data.OleDb;
I can retrieve data off of it with no problem but when I try to insert is when it fails I thought the problem was Access Rights but I do not think is the case.
I'm trying to figure out if it's possible to transfer records from SQL central database (who has a public IP address) into SQL local database (who doesn't have a public IP)?
or if it's not possible can I use a centralized website instead to pass some data into the local website? (but i'm not sure if it will have some security concerns)..
Creating a system with web front end and SQL backend (microsoft obviously). I have tried using the asp.netsqlprovider but i can;t as i am only allowed one database on the server, so i then tried to update my current database with the triggers to input the schema into the already existing database.Next step i create my own table with two simple fields of username and password and try and authenticate that way, i can't get that to work either.
I ahve limited permissions on the network as i am a University Student. I really don't know what to do. Never had to create a log on system before and i thought it would be far simpler than this. I ahve used Microsoft's sqlprovider schema before and it worked fine. I have also authenticated via IIS and AD too before. I can't do any of those two in this instance it seems.I need an alternative for logging in users, if needs be in can be crude. I also still need to have some kind of two different views too for logged in users and not logged in users, but that can change if needs must.Don't let me down people, haha. Think this posts in the correct place, i could not find another one i thought could be more relevant.

View 1 RepliesI have a development database and one in production. There are two different sets of data in each database. On my dev system, I have mostly dummy data that I test with and in production is the real data for my web application. I recently added a new feature to the app that required a new table, and a new field for a foreign key in an existing table. I now need to upload that new structure to the production database without overwriting the live data with my test data.
If I run the Database Publishing Wizard, and choose "Schema Only" will it import the new structure and leave the existing data alone, or will it drop the records in my production database tables?
I have created a sdf database in a mobile application.Now I want to synchronize that database to a sql server database.
