I make use of SMO namaspace to get Table, Function, Procedure names from the DB.
Now I've intended to get the tables [Column] name and the relation (dependency) among the tables. Is this possible?
I have such entities
Then I tried to retrieve node type from Node this way - Nodes node = Entities.Nodes.First(); string nodetype = node.NodeTypes.Name; but for some reason node.NodeTypes equalls null despite fact that there is some records in NodeTypes table.
I have one dataset in which there are 40 tables. Now i want to make a relation between these tables and show important data in grid. How do i do this?

View 2 Replieswhen i create my entity data model i have a situation in the DB like this :
TableFirst : [Id,IdTableSecond,IdTableSecondAgain];TableSecond[Id]
Created data model is: TableFirst.TableSecond and TableFirst.TableSecond1
Question is: Every time when i create my entity TableFirst.TableSecond will have same relation in behind (IdTableSecond) and TableFirst.TableSecond1 (IdTableSecondAgain)
or they may change?
I have a table that contains item data. If the item is a particular type further information exists to describe the item. The additional information isn't that heavy however the number of records in relation to the main file will be quite small (less than
5%).
So I have 2 scenarios:1) Put the additional data in the main table and take tha hit on storage
2) Create an additional table and link the 2 together
If we were talking huge amounts of data I can understand that 2) would be the obvious choice but given the simplicity should 1) be a consideration?
If 2) is the answer - is it possible to create a dependency between the 2 tables when the item is 'that' particular type. In other words wnsure the addition data is populated for the required items and not others.

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.

One of my classes currently is a C# class. I was given a small assignment for creating a bare-bones Facebook clone. I am now ready to list wall posts on user's pages.Having just been taught about DataLists (using tables), I thought I'd use one. However, I'm told "The messages list must be displayed without using table tags (<table>, .<td>, etc.)"
This is not really a coding question, just asking for a recommendation on how I should go about displaying posts without tables while still easy on the eyes (including name, the poster's picture, the message, and a date).
My SQL Server db was installed before I installed VS2008. What happens when I create the standard ASP.net security it does not create the tables and SPs that are needed.

When I move those panels from the table to outside the table they are seen in code - so I obviously can't put them in that spot.What is the preferred method to have optional columns in table/repeaters?
I recently read Scott Mitchell's article series "Examining ASP.NET's Membership, Roles, and Profile". In Part [URL], It says "to store additional, user-specific fields...If you are using the SqlMembershipProvider, this would mean creating an additional database table that had as a primary key the UserId value from the aspnet_Users table and columns for each of the additional user properties."I created a table named Thread to store some specific users information and comments they make. I set the ThreadId as the primary key and the UserId as the foreign key to the UserId in aspnet_Users table. But when I run the application and use a user's account to submit a comment, there is an error in my Comments.aspx.vb page "Cannot insert the value NULL into column 'UserId', table 'ASPNETDB.dbo.Thread'; column does not allow nulls. INSERT fails.The statement has been terminated."How can I make the logged-on user's UserId inserted into the Thread table when storing the user's other data information?

I was trying to find out how I can join more than 2 tables using the LINQ-to-SQL syntax. For instance, joining 2 tables in SQL:
SELECT * FROM Table1 AS T1 INNER JOIN Table2 AS T2 ON T1.Key=T2.Column1WHERE T2.Key='17';
can be expressed as:
var Result = from T1 in DbContext.Table1 join T2 in DbContext.Table2 on T1.Key equals T2.ForeignKey where T2.Key=17 select new { T1, T2 };
But how would I join 3 or more tables using LINQ? For example:
SELECT * FROM (Table1 AS T1 INNER JOIN Table2 AS T2 ON T1.Key=T2.Column1) INNER JOIN Table3 AS T3 ON T3.Key=T2.Column2 WHERE T2.Key='37';
I've been searching and experimenting and I cannot seem to find any informraiton on this. One example I found involves putting the result for the frist join into a temp object, and then performing the second join. I'm not sure performance-wise if that's the same as doing a 3-table join directly using a single SQL statement.
I'm using SqlDependency to control my cache. I want to use it to monitor several tables (around 10). There should be one SqlDependency per watched table.
Should I create for each of them code like that:

or can I reuse something between them? Like connection?Is this the preferred way of setting multiple notifications?
I need to copy rows for 2 tables from one db to another.I want to be able to do identity insert, one way is to change the column to not be PK.if I mark the pk not a pk but just a column, can I still map it as an ID?
View 1 RepliesI have a scenario, I will pass a StatusID , According to that StatusID , The rows will be fetched from a table[tblEventStatus] and newly fetched row has to fecth the data from another table [tblEvent].
Ex: StatusID - Value I am Passing
Table 1: tblEventStatus - Column:SysID - StatusId - EventID
Table 2: tblEvent - Column:SysID - EventID - EventDesc
I want to use the Linq - I tried like this, But It doesnt work
var query1 = from objtblEventStatus in db.tblEventStatus
where objtblEventStatus.StatusId== StatusId
join objev_events in db.tblEvent on objtblEventStatus.EventID equals
(objev_events == null ? null : objev_events.UID)
