Suppose we want to select the data from the database then we write the query for that. Example:
SqlConnection con=new SqlConnection(Connetion name) string selectPkId = @"SELECT PK_ID FROM TABLE" SqlCommand cmd=new SqlCommand(selectPkId ,con);
So,my question is that why we basically use @ before the sql query.If I don't use @ before that then it again work fine (does not give any error), then what is need of using "@"?

What is difference between select { } and select new {} In Linq Query
View 3 RepliesI am writing a linq query to select a blogpost,
[code]....
The blogpost i am testing got 3 tags attached to it. The table structure is:
(table)BlogPost -> (table)BlogPostTags <- (table)Tags
So the BlogPostTags table only contains 2 fields, BlogPostID and TagID.
When i run the query above i get 3 results back. Same blogpost 3 times but with 1 tag in each. It should return 1 post with 3 tags. The problem lies in the Tags query above.

View 4 RepliesI'm using Access 2007 for a project and I'm trying to run the following parameterized query:
string sql = "DELETE * FROM participants WHERE participant_id = @participant_id"
OleDbCommand command = DataAccess.NewCommand(sql);

command.ExecuteNonQuery();
The really weird thing is that it will work if I hard code the value:
string sql = "DELETE * FROM participants WHERE participant_id = 1"

View 5 RepliesLot of times I did edit, delete, insert in my webproject in different pages but I am very surprised that why I am not remembering the technique to do these task. Actualy I never take any course on asp.net/vb.net, what I did in my project just to take help from forum or asp.net website etc. I get a task again to make a web interface having functionality to view data and provide Edit functionality also. The other task is to click a link in the same page to open a new page with the fields of the same table to insert new record.
Q1: Is it necessary to take a dataset or I simply do it using sqlDatasource?
Q2: Could anyone give me a very basic and simple vb.net/asp.net project with all above tasks so that I will do a practice project and never miss it?
I have a table of solicitors with three fields: ID, First, Last.
I created a page with a dropdown that has all the solicitors by their full name (First + ' ' + Last, example "John Dow") and a delete button to delete them from the above mentioned table.
I added a delete query to the solicitors table adapter in the xsd that looks like this:
[Code]....
I named the query "DeleteByFullName"
Here is the vb code for the delete button click event:
[Code]....
The problem is that the xsd expects the Original_ID as an argument and not @FullName
