DataSource Controls :: Filter A DataView To Return All The Rows Whose Column X Starts With A Number
Jan 29, 2010
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?

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 want to check that the row index I specify is below the row count so it doesn't throw the error
Index 2 is either negative or above rows count.
how would I achieve this with my code?
Using connection As New SqlConnection(connStr)
Dim command As New SqlCommand
command.Connection = connection
connection.Open()
Dim a As New SqlDataAdapter("SELECT top(3) name, (SELECT TOP (1) ImageId FROM Images WHERE(productid = products.Id)) AS imageId FROM Products WHERE beginnerdiscount = '1' ORDER BY Dateadded", connection)
Dim s As New DataSet()......

I'm using a table adapter to perform my queries. I'm sure I'm missing something really easy, but I can't figure out how to return the number of rows returned from a query to a dataset used for a GridView.Basically, I want to display a message "No records exist for your selection" by testing for ReturnedRows = 0.
Excerpt of C# code:
handoutDSTableAdapters.handoutTableAdapter handoutsAdapter =
new handoutDSTableAdapters.handoutTableAdapter();
gv_Handout.DataSource = handoutsAdapter.GetDataByDoctor(Int32.Parse(ddl_MD.SelectedValue));
gv_Handout.DataBind();

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 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.

I currently have a datasource that displays several rows on an editable gridview where the user can update several rows at once. Each row contains an ActivityTotal column per row. I'd like to sum all the ActivityTotal rows displayed and have one totalValue.
for example
row 1 activityTotal = 4
row 2 activityTotal = 3
row 3 activityTotal = 1
totalValue = 8
How can I incorporate this into the code?

I need a way to read all the rows in one column from an Excel file that the user picks from a fileupload control. I tried saving the excel file on the webserver with the upload control and then opening it with a OleDbConnection but that fails when running it from the webserver and gives the error:
Request for the permission of type 'System.Data.OleDb.OleDbPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
This works fine when just running it localhost, so i figured it might be a problem with security level at the webserver which i cant change. Instead i tried doing it with a streamreader direct from the fileupload control and because theres no need for saving the excel file on the server, but im not sure how to query the rows i need this way.

Here is the query I have now which returns over 2 million records:
[Code]....
This works, but the result is littered with many rows that contain the same SSN. So how do I return only one row for each ssn? I cant use distinct because all of the other columns are already always different, this would return the same as above.

What I want is to filter the dataview so I get top 10.
I googled it and found out that I had first to sort the dataview. Then add a column (int) to datatable. This column I then made a AutoIncrement on......
This works fine - I can see in the codebehind that it adds a column to the datatable that I called AutoInc.
Then make a RowFilter on the dataview - here it goes "wrong" for me.....
When using the line
datVie.RowFiler = "AutoInc < 11";
and bind it to a gridview I don't get a error - but it also don't show me any rows in the gridview...... If I comment the line out - I get all the rows in the dataview..
Can anyone see in my below code what is wrong?

In my organization we use nested groups. For a particular usage, we have a group (let's assume that the group name "kuku"), and the names of all the nested groups under it contains "kuku" as well.
We may assume that no other group in the LDAP has "kuku" in the name.
I need to create a filter which will return all the users which belong to one of the "kuku"s group.
Obviously, using this filter will bring only the head kukus
(&(&(objectclass=user)(objectclass=person))(memberOf=CN=kuku,cn=...rest of the group DN...))
How can I use wild card to fetch all users which belong to any kuku?
For example: (&(&(objectclass=user)(objectclass=person))(memberOf=CN=.*kuku.*))

I'm not sure if the topic describes my problem very well but I am creating some HTML elements (textboxes) on the fly with jQuery and I never know how many I will create (it loops through a database). I then want to get all the elements in the code behind and perform some actions (insert them into another database).
I know I can use
string n = String.Format("{0}", Request.Form["hiddenField0"]).ToString();
To get the first textbox but what if Idon't know how many textboxes I have created and want them all? Their name starts with hiddenField plus an incrementing number.
Is there a way to loop through all elements that has a name that starts with a certain string?

I know how to do this in a datatable but I would just like to learn how to do it in a dataview.
I have a dataview which is used to populate a gridview. It has the following column
userid Location
123 New York
124 Chicago
125 London
Now, I would like to know how to determine the 124 row and highlight it to a blue in a dataview used to populate a gridview. kindly note, i can do this in a datatable but not a dataview. I would like to learn how to do it in a dataview.
