Right now, inside the access file, the mssql tables are set up as linked tables so queries can be written using tables from both databases. (e.g. "select * db1.table1 where db1.table1.somevalue not in db2.table1", or select into tables like that one)These queries need to be moved into a VB.NET project, but still be linked to the access file.ng loops or something?

View 4 RepliesI want to design a application which can support two different types of databases same time e.g; when we install, it will ask which db it has to support and based on initial selection it should work with any db without changing anything in the application.In short it has to be developed keeping in mind that user may have either MS SQL or MySQL. It should support both.

connect my vb.net application to a remote sql server database, so every one who installs the application would be able to connect to the same remote database. the application would obviously require the internet to run.i also want the option to add more databases in the future, preferably one for each business who would use my software.i am wondering the best way to set up this server that could hold multiple databases. i would think i have two options:
1) set up the server myself on a dedicated computer
2) pay for some type of service that host sql server dataases
so how would i go about executing these options? i dont know the first thing. which option is better?i do however know how to connect to a remote database so thats not what i am asking.

I'm working on an ASP.NET 4.0 site, which I inherited ownership of. It has a number of existing LINQ datasources pointing to individual tables. For example, to the Patient Encounter Summary table in SQL Server. The problem is in displaying the data there. It's a normalized database, so that table contains (for example) the provider ID, rather than the provider name.
It's simple enough to join the Patient Counter Summary to the Providers table (in SQL)... but how does one do that in ASP.NET? I'm not sure of the correct nomenclature, but the 'mid layer' is VB.

Every time I execute my application and the app try to access the database I received an error message telling me that the user cannot login into the database. This is because the VS Server Explorer have the connection opened. What I need is that every time I debug (F5) my app the Server Explorer close the connection with the database so I do not have to stop the execution and manually close the connection. Is this is possible? Is there any way I can setup the debug or the Server Explorer to do this?

View 2 RepliesI have two tables as follows:
Customer | Product
------------------
A | Car
A | Bike
A | Boat
[Code].....
If I use a normal JOIN then I get a list of friends for every separate product. I just want the two lists once.
The output lists with '-' need not be table cells, they can be <ul>s.
How can I achieve this? I would like to bind to ASP.net GridView. Should I try to do it all in one query, or use multiple queries and somehow add them both to the same Grid?
Each row actually forms part of a long report. Essentially each row of the report contains Customer ID, a bunch of other fields which match one-to-one with Customer ID, then the two lists for each Customer ID I described. Perhaps I can use a separate query for each list, then manually add each list to the grid on RowDataBound or similar?
Iwant to join two tables,'Employee' and 'Dispatch'. Dispatch has column 'DispatcherID' and 'TechnicianID' which are both foregn keys to EmployeeID in Employee table.I want to join these two tables using EmployeeID so that i can obtain the matching name to each id.but it only works when i make a single join to either DispatcherID or TechnicianID and not for both.

I am looking to define data types by fields in SQL Server 2005. My source is an Excel spreadsheet and I cannot define by columns because each row requires a set of definitions applied to each field in that row. Ex, row 1 requires field1 to be CHAR while in row 2 field 1 needs to be DATE.
View 1 RepliesI have a class with a Property called 'Value' which is of type Object.Value can be of any type, a structure, a class, an array, IList etc.My problem is with the setter and determining whether the value has changed or not.This is simple enough for value types, but reference types and lists present a problem.For a class, would you assume that the Equals method has been implemented correctly, or just assume that the value has changed every time the setter is called?If I did assume it's changed, then perhaps I should assume it for value types as well, so that the behaviour is consistent.
