Accessing Value From SqlDataSource
Jan 24, 2007
I have a SqlDataSource that returns a list of companies and their details by ProductID. It also returns the name of the product associated with the ProductID as the final column (which means it appears for every record returned). I already have a way of determining how many rows were returned, and use that information in a label to say "Your search has returned x records".
protected void dsGetSuppliersByProduct_Selected(object sender, SqlDataSourceStatusEventArgs e)
{
int RecordCount = e.AffectedRows;
if (RecordCount == 0)
{ lblRecordCount.Text = "<p>No Records found"; }
else
{
if (RecordCount == 1)
{ lblRecordCount.Text = "<p>Your search returned 1 record"; }
else
{ lblRecordCount.Text = "<p>Your search returned " + RecordCount + " records"; }
}
string ProductName;
}
How can I access the ProductName value so that I can extend the label text to say "Your search has returned x records for <ProductName>" ?

I am using a drap and drop SQLDataSource control. Everything works like I am wanting it to, but I want to check a value from one of the fields that I have retrieved. I am lost as how to retreive just the field. If I have to create another dataset to do the work what is the point of using the drag and drop control? I would really like to just access the dataset fields as needed.

First let me give you a little back ground on me. I'm very new to the ASP, ASP.NET, Visual Studio, Sql Server, Frameworks....thing. I am coming over from a PHP/MySql background of over 5 years. The change over to VBScript and VB has been to tough and I have a basic liking for the Visual Studio 2005 and the ease of putting things together. However, I have come across something that to me seems like it should be relatively simple, but haven't been able to find the documentation or samples to describe what I'm looking to do.
Rough Need:
1. Start with a form will a couple labels and a singe textbox to get the lookup date from an user.
2. Query one table/view based on the users choice of date and select only one field of returned data.(Doing this by itself is not a problem and I can display my results in a Gridview, but this is where it starts getting tricky and the gridviews won't work for me.)
3. If there is something returned, I need to start a HTML table layout or possibly some form of a Gridview(I don't see how I would use the Gridview) and start a loop, adding the first returned row from this query into the first cell.
4. Now, based on that same User Date and the returned row value from the previous query, I need to query another Table/view and return another single field, which might return 1 or multiple rows, which I need to start a loop to display unique items in cells under the first on above.
5. Based on the original User Date and each returned row from the first query, I need to query two other Table/views and get some additional information. 4-5 fields will be returned and be displayed on one row in the number of necessary columns.
6. This would finish the first row from the first query, so I would need to loop back up to see if there were any further results and continue looping until the get to the last of the results from the first query.
7. Finally, I would just need to close up the Table/gridview.
The basic results I'm looking for would be similar to the following:
Results for 10/11/2005
Field name 1
Field name 2
Field name 3
Field name 4
Field name 5
First Result from query 11 of 4 results from Query 2, but only 1 unique result
Info from Query 3
Info from Query 3
Info from Query 3
Info from Query 4
Info from Query 4
Info from Query 3
Info from Query 3.
Info from Query 3
Info from Query 4
Info from Query 4
Info from Query 3
Info from Query 3
Info from Query 3
Info from Query 4
Info from Query 4
Info from Query 3
Info from Query 3
Info from Query 3
Info from Query 4
Info from Query 4
Second Result from query 1First result from Query 2 after looping though the first query Second result from Query 2 after looping though the first query
Info from Query 3
Info from Query 3
Info from Query 3
Info from Query 4
Info from Query 4
Info from Query 3
Info from Query 3.
Info from Query 3
Info from Query 4
Info from Query 4
Info from Query 3
Info from Query 3
Info from Query 3
Info from Query 4
Info from Query 4
Info from Query 3
Info from Query 3
Info from Query 3
Info from Query 4
Info from Query 4
It seems me from what I have read and slowly figuring out, is that I should be able to directly access the DataSet returned by four SqlDataSources, one for each of the above querys and then just write my own VB to handle the necessary looping, table format and such. I can easily add the for SqlDataSources to the page and add a Gridview for each one and get 4 separate chunks of info, but can't see a way with GridViews to intermingle the info like displayed above.
So, if it can be done with Gridviews, then I would love to see how that is done. But, if someone could explain to me how I access the DataSets directly that I get from the 4 SqlDataSources, then that would be ok too. I have figured enough out with VB, that I can write the code to do my looping requirements, if I can just access the information I get back. Thanks for reading all the way through this long post.

Hi
I think I've programmatically created a SqlDataSource - which is what I want to do; but I can't seem to access details from the source - row 1, column 1, for example????
If Not Page.IsPostBack Then
'Start by determining the connection string valueDim connString As New Data.SqlClient.SqlConnection(ConfigurationManager.ConnectionStrings("ConnectionString").ConnectionString)
'Create a SqlConnection instanceUsing connString
'Specify the SQL query
Const sql As String = "SELECT eventID FROM viewEvents WHERE eventID=17"
'Create a SqlCommand instanceDim myCommand As New Data.SqlClient.SqlCommand(sql, connString)
'Get back a DataSetDim myDataSet As New Data.DataSet
'Create a SqlDataAdapter instanceDim myAdapter As New Data.SqlClient.SqlDataAdapter(myCommand)
myAdapter.Fill(myDataSet)Label1.Text = myAdapter.Tables.Rows(0).Item("eventID").ToString() -??????????????
'Close the connection
connString.Close()
End Using
End IfThanks for any helpRichard

I've found example code of accessing an SQLDataSource and even have it working in my own code - an example would be Dim datastuff As DataView = CType(srcSoftwareSelected.Select(DataSourceSelectArguments.Empty), DataView) Dim row As DataRow = datastuff.Table.Rows(0) Dim installtype As Integer = row("InstallMethod") Dim install As String = row("Install").ToString Dim notes As String = row("Notes").ToString The above only works on a single row, of course. If I needed more, I know I can loop it.The query in srcSoftwareSelected is something like "SELECT InstallMethod, Install, Notes FROM Software"My problem lies in trying to access the data in a simliar way when I'm using a SELECT COUNT query. Dim datastuff As DataView = CType(srcSoftwareUsage.Select(DataSourceSelectArguments.Empty), DataView) Dim row As DataRow = datastuff.Table.Rows(0) Dim count As Integer = row("rowcnt") The query here is "SELECT COUNT(*) as rowcnt FROM Software"The variable count is 1 every time I query this, no matter what the actual count is. I know I've got to be accessing the incorrect data member in the 2nd query because a gridview tied to srcSoftwareUsage (the SQLDataSource) always displays the correct value. Where am I going wrong here?

What is the C# code I use to do this?
I'm guessing it should be fairly simple, as there is only one row selected. I just need to pull out a specific field from that row and then insert that value into a different SqlDataSource.

Hi!
I have two assets: a URL that points to an XML file, and a stored procedure that can accept this file as a text variable and store it in a SQL 2005 table.
create procedure [dbo].[insertObjects]
@availabilityXml text
as
DECLARE @xmlHndAdd INT
EXEC sp_xml_prepareDocument @xmlHndAdd OUTPUT, @availabilityXml
TRUNCATE TABLE Objects
INSERT Objects
SELECT *
FROM OPENXML(@xmlHndAdd, '//NewDataSet/Table1', 2)
WITH Objects
Now, I need to find a solution to combine the URL with the proc. Does anyone have any suggestions on how I can pass my URL as a text variable to the procedure? SSIS, vb-script, etc. are welcome!
Thank you!

I am trying to execute an SSIS package (which accesses a dbf file through an odbc connection) through a Sql job, but the package log reports an error of "Disk or netowrk error". When I execute the package in the IDE, the package executes fine. When I run the manifest on the DB server, I can execute the package with no errors. But, when I create the job, and try to execute the job, it fails. I thought at first that the user didn't have privileges to the directory that the file existed in, but that isn't the case.
Can anyone shed some light on how to accomplish what I am trying to accomplish? It seems like this would be a common use of SSIS, but I cannot seem to get it to work.
Thanks in advance for any assistance you can provide!

Hi, I am developing a small asp.net application where I read from a readonly omnis database via odbc then dependant on user input write records to a second database.My first idea was to use an odbc connection to Omnis database and write to ms sql database. There is quite a few queries that need to be made to the Omnis database and I am binding a datagrid to the MS Sql server database. I was hoping to use stored procedures to update the mssql tables. So there will be much opening and closing of connections. Should I go down that road or should i think of using an Access database, with linked table to the Omnis database, then only one connection needs to be made. And I can store my information in the Access database tables. Thanks.

Hey All
I wish to display the 3rd and 4th to last records of a table on a page. Is there anyway of doing this? I can access the last records by using Count and TOP 1 but i find that count - 1 as the ID to select can be errornous if records are removed from the table. I also tried using ORBER BY followed by LIMIT but kept getting an error in order by clause message.
Any help would be greatly appreciated

Hi
If my site is hosted with an external company web host can I use ASP.NET pages to connect to a MS SQL DB that is on my company's internal server if I had MS SQL installed on it?
My company's server is always on and always connected to the internet.
I have access to my company's server if I need to set anything up on it for this to happen.
There will not be any kind of overload as the site is not accessed constantly.
Also, would this cause any kind of security leak? If so how would I go about plugging this hole?
Our server does have confidential info on it.
Cheers

I'm new to databases as you probably can tell. A friend sent me three data bases, which in my mind should have been one database with all the tables included, but he didn't. So my question is, can you pull info from two databases in the same query?
I write the query acessing one database and the result chart must depend on a where predicate based on accessing tables in another database. If this isn't possible, how do I get the tables I need together, that presently reside in differing databases?
Thanks for the help in advance.

Hello all,
We are planning to migrate an application written in Perl + mySQL to .NET + MS-SQL Server. The test machine now has SQL Server running. During the development phase in .NET, we would want to access the mySQL database which is being updated at real time, from the Windows box. This is how I think it has to be done:
1. Use DTS to migrate data from mySQL. Does DTS take care of migrating schema and the difference in data types between the mySQL and MS-SQL? Is there any 3rd party software out there that takes care of the migration without any manual labor?
2. Synchronize the data between 2 DBs by creating some kind of a batch job? If so, whats the best way of doing this?
Instead, is it easier to access the live mySQL database on the Linux box from the .NET code and move the DB only after development in the new environment is completed?
Any help/ideas is greatly appreciated.
TIA

I have to troubleshoot a problem with a complex sproc that is running against a number of views that select entire tables from another "production" database. The problem we are having is that while the views should be read-only, there are no transactions, and no locking, the application's process on SQL Server is blocking anyone else who tries to write data. I'm wondering if this method of using a view as a proxy to another DB is effecting the block. The reason for doing this was to improve performance by offloading the production DB, but since it's the same instance of SQL Server, does it really matter? THX for your advice.

Hello everybody.
I'm having a problem:
As the result of Dataflow task I get a recordset with about 50 columns in it. Now I need to loop through each row in the dataset and make some manipulations with the data in all 50 columns in a single script task. So I need 'em as separate variables.
Ofcourse I can make a For Each Loop container with ADO enumerator, and map each column to specific variable. But that's not a very good thing, because if the format changes, i will have to remap everything again (takes a lot of time to remap 50 values)
So is it possible:
1. To map using not index of columns, but there names?
2. To pass actual row into the script task?

Greetings. I am curently having problems with authorizations while attempting to connect to SQL Server with an Asp.NET web application. I will try to explain my problem as clearly as possible.
I am developing an Asp.NET web application with Visual Studio to connect and view a database on a remote SQL Server. In my Web.config file, I have added the line
<identity impersonate = "true"/>
In my IIS security options, I have disabled the annonymous authentication and enabled the Windows mode authentication instead. When accessing the database from my computer, by compiling and debugging my web application in Visual Studio, everything works wonder. When I try to use the web application from a remote computer using the IP address or from my own computer using localhost in the URL, it asks me for my Windows username and password, which I provide, and then refuses any further access, saying I don't have permission to even connect to the server.
How can I go around this and allow my users to connect to the server from a remote computer? My machine is running Windows XP SP2 and the server is running Windows Server 2003.
Thank you in advance for any help you may provide,
Marie
