I have executed my query in VB with:
[Code]....
I now want to count the number of returned rows so that I can say:IF rows_returned = 1 then login else deny
I think you get the idea.P.S. I know this is not the most secure method of login but I do not want to use the ASP.NET configuration manager as I like to understand what is happening. I am starting off very simple and I shall work up from there.

When a user submits the query to SQL when clicking a button I need to get a count of the number of rows that are returned. Which event does the gridview.count code need to be place in?
Right now I have it in the btn_click event, but in order to get it to count the rows you have to hit the button twice since the query is not returned yet. Here is my code.

I am trying to show as part of the Gridview table the amount of records found as a total in one of the Gridviews rows. I have some code which does add a row to the Gridview but it does not seem to be counting the number of rows it just shows 0 all the tim. Does anyone know why this might be? you can see the count "visitCount" and the dt.Rows.Add but it doesn't increment

I want to calculate the number of HOLIDAYS between two given dates. For example, to count the number of 'Fridays' and 'Saturdays' and any other holiday (can get from another table) in between two given dates.
For example,
Start Date: 16/07/2010
End Date: 22/07/2010
Holiday: 19/07/2010
OUTPUT: 3 Holidays (Since there are only two Fridays and Saturdays and one Holiday)
do also note that it must include count if the starting day or ending day is a holiday.

I am working on a small project. I ran the query below to get the maximum userid and increase it by 1 to create a new userid. However, when I run the query, it does not display the values that I enter into the database using insert statement. For example, if I open the table called login, I can see there are three records. If Irun the select statement, it only return one record which is the one that I enter manually when I first created the table. If I run the same select statement and give it a user id that I created, it returns the correct result.

I am accepting query/queries from user (our support team) in a text box where user can enter only one query or multiple queries. I need to display result of all queries entered in the textbox. If it is SELECT statement then result of that statement in grid which is done. If UPDATE/INSERT/DELETE then total number of rows affected which is also done but if only one UPDATE/INSERT/DELETE statement is entered in the textbox.
If user enters 2 UPDATE statements and then a SELECT statement then how can I get number of rows affected for individual UPDATE statements just like SQL Server Qury Analyzer displays messages in its result pane.
e.g.
(6 row(s) affected) -- first UPDATE statement
(4 row(s) affected) -- second UPDATE statement
(16 row(s) affected) -- for SELECT statement (grid will also be displayed along with these messages).
I tried almost everything, SqlDataSource (returns count of first statement only), SqlCommand.ExecuteNonQuery and DataAdapter.Fill (returns count of last statement only).

I'm trying to filter a DataView to return all the rows whose column x starts with a number: The following works in SQL Server:
select *
from dbo.Page
where Name like '[0-9]%'
However, when I try this:
dataView = new DataView( someDataTable, "Name LIKE '[0-9]%'", "Name ASC", DataViewRowState.CurrentRows);
I get "invalid parameter [0-9] with Operator Like" error message. What is the correct syntax to achieve my goal?

Never really worked with the asp tables but for this project it makes more sense, I am having trouble addding rows dynamically from the sql datatable i am pulling. In hte datatable it has 12 rows with 14 columns, I need to make this into a table, with a dtagrid I would be done but I have to pull other data that they could add columns, so a table I am told is easier.
This gets my data and I can see it
mydataTable = new DataTable
mydataTable = GetData(sql)
mydataTable.add.row(myDataTable.rows(0)(0))
I get nothing but errors trying to do this, what is the correct way to add rows to an asp.net table
Can I add this all to a datagrid and then add the extra columns I need if they are there with out using a table.

I am generating a unique Ref number using this sql statement: SELECT REPLACE(STR(CAST(CAST(NEWID() AS binary(5)) AS bigint),12),0,0) as REF Subsequently, I need to insert this REF into sql database table in stored procedure. Here is what I did in my stored procedure:
USE [iBankRecords]
GO
/****** Object: StoredProcedure [dbo].[stp_addPayee] Script Date: 07/05/2010 21:57:07 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROC [dbo].[stp_addPayee]
(
@CUSTID char(10),
@PAYEEACCNUM nvarchar(20),
@PAYEEACCTYPE char(10) ,
@PAYEENAME char(20),
@PAYERINITIAL char(20),
)
AS
DECLARE
@ReturnValue int
INSERT INTO PAYEE (CUSTID, PAYEEACCNUM,PAYEEACCTYPE,PAYEENAME,PAYERINITIAL, REF)
VALUES (@CUSTID,@PAYEEACCNUM,@PAYEEACCTYPE,@PAYEENAME,@PAYERINITIAL, REF)
IF @@ERROR<>0
BEGIN
PRINT 'ERROR'
SET @ReturnValue=1
RETURN @RETURNVALUE
END
ELSE
BEGIN
SET @ReturnValue=0
RETURN @RETURNVALUE
END
May I know how do I have generating a unique ref num and inserting the REF into the above statement?

I am counting from a table for that i have written code as below
protected void get_Id_Afterpoint()
{
int counter = 0;
string strSql = "select count(*) as ID from tblEnergy where ID=?";
OdbcCommand com = new OdbcCommand(strSql, con);
com.Parameters.AddWithValue("ID", DropDownList1.SelectedValue);
OdbcDataAdapter oda = new OdbcDataAdapter(com);
DataTable dt = new DataTable();
oda.Fill(dt);
if (dt.Rows.Count == 0)
{
lblID2.Text = "1";
}
else
{
counter = dt.Rows.Count;
counter = counter + 1;
lblID2.Text = Convert.ToString(counter);
}
}
there is no record related to DropDownList1.SelectedValue. but as i am counting if(dt.rows.count) and i put break point on the bolded part it shows 1 record. how it can be possible?
