DataSource Controls :: How To Access The Return Value Of The SQLDataReade
Feb 15, 2010
accessing the return value of the SQLDataReader. My code is below. Actually the variable that I assigned my SQLDatareader object to is say HasRows property=true. But I am having trouble accessing the return value. And I get the error when I use the following code .Text =SQLDataReader("Contact Name").ToString I get the following error message: Invalid attempt to read when no data is present.
con = New SqlConnection(ConfigurationManager.ConnectionStrings("Connect").ConnectionString)
Dim getDirectorsCMD As SqlCommand = New SqlCommand("dbo.spGetDirector", con)
getDirectorsCMD.CommandType = CommandType.StoredProcedure
Dim myParm As SqlParameter = getDirectorsCMD.Parameters.Add("@BuildingTID", SqlDbType.Int, 15)
myParm.Value = ddlBuilding.SelectedValue

It reset my table Identity value However, when I call it from my function reset, it returns -1, and does not reset my table identitity value. The function to restet my identity value is:

I 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.

I have 2 tables. Table_A has one to many relationship with Table_B.
For example. Table_A has an ApplicantKey and in Table_B I am storing (Resume_name and CoverLetter_name for the Applicant). Joined by ApplicantKey
Now when I join them and execute the query obviously it returns me two rows. But what I want is that it should return only one row with Columns like Resume_name, CoverLetter_Name

I have this query:
[Code]....
I want to select dates that also fallin the range. Heres the scenario: I have an event from 01/20/2010 TO 01/25/2010. So right now it would only return a date of 01/20/2010. How could I return 01/20/2010, 01/21/2010 , 01/22/2010, 01/23/2010, 01/24/2010, 01/25/2010? Mind you only a start and end date are in the database.

I have a select statement in a stored procedure and want to be able to retrieve the key column value (PRODUCTID)and return it as Output when Select statement is executed on input Parameter (NAME).
addition, return two further output values (COST,TOTAL).
note the grid control expects to receive all values at once! so i need to get out these values at the same instance of execution.
Select productID,COST,QUANTITY,NAME,TOTAL,DATE
FROM PRODUCTS
WHERE NAME=@NAME

I have the following simple stored procedure:
ALTER PROCEDURE GetadiByPhiNo
@PhiNo int
SELECT adirefno, adidescription
FROM aditable
WHERE adiphino = @PhiNo
Here is an example of data returned:
1 Skin diesease
2 Cough
3 Cough
4 Rash
You notice "Cough" is in the adidescription column twice. I would like to return only one row for adidescription with the same value. So what I want returned is this:
1 Skin diesease
2 Cough
4 Rash

So I am getting this error message:
Cannot implicitly convert type 'System.Data.SqlClient.SqlParameter' to 'string' I have a stored procedure on SQL 2000 returning an email from a database table (aspnet_Membership). The email type from the table is nvarchar. I have a method (in C# in the code behind) that gets that value. But the debugger doesn't like the last line:
return returnEmail; // returnEmail is a string variable we created to capture the stored procedure's return value
I've tried doing returnEmail.toString() in several places, but still get the same error message for the last line of code (returning the email).
This is the stored procedure:

I have a stored procedure which returns a value to state if the userlogin is valid. but i want to return the data and store it in a data session as i will require the user details in the checkout page.
is it best to get individual parameters out of the stored procedure then assign the variables to a datatable which is then assigned to session Or how can i get all the details returned from the stored procedure for the table? not sure which would be the most effective solution?

I have an SQL database table like the following:
ID // Code // Shape
The ID is the integer identifier.
On one line the Code may be OX01 and shape Hexagon for example
Then the next line the code is still OX01 but the shape is Triangle.
What I want to do is be able to pull back data for every line that is equal to a unique Code column. in the above example OX01 Hexagon would be returned but not OX01 Triangle.
I've tried using SELECT DISTINCT but it brings back all records and doesn't filter them correctly.
I've considered having another column which could have Child/Parent data so that only the parent is returned but i'm sure there must be a better way of doing this.

I've looked all over for this answer and had to resort to several resources. I wanted to post this here because it was so hard for me to find a simple example. If it exist other places then please excuse my post and put references to it on a reply.
So, How do I return the Primary Key Identity when I click the control with the 'Insert' command on a FormView? (With very least minimal code) Help me if there's a quicker way.
<InsertItem>
<SqlDatasource ID="sqlSource">
<InsertCommand = "INSERT INTO ... ; SELECT @ID = Scope_Identity()">
<InsertParameters>
<asp:Parameter Name="ID" Direction="Output" Type="Int32" />
</InsertParameters>
</SqlDatasource>
</InsertItem>
Protected Sub sqlSource_Inserted()
Dim cmd as System.Data.Common.DbCommand = e.command
Dim strID as String
sqlSource.InsertParameters("ID").DefaultValue = cmd.Parameters("@ID").Value.ToString()
strID = sqlSource.InsertParameters("ID").DefaultValue.ToString()
lblResults.Text = strID
End Sub

I have a user table with userID, userName ...the standards. I also have a "Material" table with materialID, materialName, etc.
I combine these in another table "UsersMaterial" with userID and materialID, depending on which materials the user has chosen (between 0 and 5).
Now I need a stored procedure that returns the user information + the set of materials that is mapped to the user.
But I can't see how I can return one row of user information combined with a set of the user materials? Do I join or can I return a set + one row?

I am trying to return a dataset. I must be doing something wrong. The returned dataset in this sample code indicates there is a datatable, Users, but there are no datarows. What am I doing wrong? This example is only using the rows.count, but of course I really need to use the whole datatable as the datasource for a gridview.
[Code]....
Public Function getmyds() As DataSet
Dim dsUser1 As DataSet = New DataSet()
Dim tbUser1 As DataTable = dsUser1.Tables.Add("Users")
tbUser1.Columns.Add("UserName")
tbUser1.Columns.Add("Days Remaining")
tbUser1.Columns.Add("UserAccountControl")
Dim rwDefaultUser1 As DataRow = tbUser1.NewRow()
rwDefaultUser1("UserName") = "John Smith"
rwDefaultUser1("Days remaining") = 100
rwDefaultUser1("userAccountControl") = "Enabled"
Return dsUser1
End Function
