In one of our application the parameters passed to a stored procedure in this way
Dim parm As New SqlParameter("searchText", SqlDbType.VarChar)
parm.Direction = ParameterDirection.Input
parm.Size = 50
parm.Value="test"
cmd.Parameters.Add(parm)
and the procedure contains a parameter as @searchText
ie the parameter name passed from the code is searchText and that in the stored procedure is @searchText .
But it is working properly, i am always getting the required results.
So my question is like so there is no need to specify @ before the parameter? Whether it will append @
I know to define integer type sqlparameter but I do not know the decimal type sqlparameter for the precession.

I have a web application running written on ASP .Net.We have a class accessing the back end written in VB .net which has shared functions for DB interactions.The above error comes up when ever two users are in the same page... tying to do the same thing.Couldn't find a reason why this would happen.The scope of the SQL command is limited and parameters are cleared at the end.
I am experiementing with table updates and the code below gives me the following error message: "The variable named "@Processed" has already been declared... at the following code line: clsWTAdapter.Update("clsWTDataTable"). I fear that all of my code is a general mess, and I am sure there is a much better way to go about it.
Dim clsCmd As New SqlClient.SqlCommand Dim clsCMAdapter = New SqlClient.SqlDataAdapter("SELECT * FROM CatalogMaster WHERE Processed <>-1", clsCnn) Dim clsCMDataTable = New DataTable("CatalogMaster")
I keep getting a strange error message when I try to call my stored procedure. Possibly I have a syntax error? Not my store procedure does not return a value. Also the error message is included at the end of this post.

I created a database in Access 2010. I am thinking of creating a front end in Visual Basic and was wondering if anyone had any experience with this. Is it doable? Or should I save my time and use access's front edn?
Basically, I have an Access database with Primary keys that are structured with this format ("02"000).When I try to paste the number, it ignores the "02" and goes straight to 000.For example, here is the code;
What PeriodRoomID.Name should be is R02001.What PeriodRoomID.Name comes up as is R1.It ignores the "02" and ignores the 0s. This makes sense mathematically but it is not what I want. I need a way to get the exact output and not some simplified version.
The query;
SELECT SpecialSoftware.SpecSoftID, SpecialSoftware.RoomID, SpecialSoftwareNames.Description, Rooms.Capacity FROM SpecialSoftware, SpecialSoftwareNames, Rooms

I've selected two rows of data from one of the tables in my database and pivoted it, making two columns. What I would like to do is add a column in front of the two, and use that like a rowheader, I'm unable to use the actual rowheaders at the moment because I'm exporting the datagridview to word and I'm unsure how to get the rowheaders in, so I thought to just add in another column for the time being.
So, how am I able to add in a new column in front of the others? Or even better, how can I include rowheaders when I export a datagridview?
