Hi,
This is a very simple question but I don't have any idea of how to do it.
Says I have a table with 50 records. How do I know the number of record have been return by sqldatasource when it execute a SELECT sql statement that contains a WHERE clause. Says the 30 records match the SELECT statement, what code do I have to write in order to display the number 30?
I would like to use the value returned from my SqlDataSource SELECT method, in the INSERT method for the same SqlDataSource. Any ideas how this is done?
Hello and thank you taking a moment. I have created a simple login page where the user will pass credentials. I have a sqldatasource that will query a database to see if the user exists. What I would like to do is have the user click a button after entering their credentials. When the button is clicked I would like the SqlDatasource SelectCommand to fire and if there are rows returned then redirect the user to a new page. I know I can do this with ADO and a datareader with the HasRows property. But what I would eventually like to do is cache the data and then bind the cached data to a control(like a dataview) on the page the user is redirected to. If anyone can tell me how to get the Select command to fire on a button click I would be eternally grateful. Any help will be greatly appreciated.
I have a sql data source that runs a query that returns a users data (See below). I want to set the session variable "UserID" equal to the tkinit. How do I "bind" the session to a column from this select command? I tried this Session("UserID") = ("tkinit") but that doesn't work. I can hard code a session value, just can't figure out how to "bind" it from the sqldatasource.. <asp:SqlDataSource ID="getUserID" runat="server" ConnectionString="<%$ ConnectionStrings:xxxConnectionString %>" SelectCommand="SELECT [tkinit], [tklast], [tkfirst], [tkfirst]+' '+[tklast] as fullname FROM [yyy] WHERE ([login] = @login)"><SelectParameters><asp:Parameter Name="login" Type="String" /></SelectParameters></asp:SqlDataSource>
Hi all,I have a stored procdure which does a select and returns the recordsdirectly -i.e. Not in output parameters e.g:CREATE PROCEDURE up_SelectRecs(@ProductName nvarchar(30)) ASSELECT *FROM MyTableWHERE [Name]=@ProductNameIn another stored procedure I need to do the following:SELECT COUNT(*)FROM MyTableWHERE [Name]=@ProductNameAs the select queries are actually a lot more complex that this, I'drather not duplicate the select code in 2 sp's to save the maintenanceeffort - I'm looking for a way to execute the first procedure from thesecond and just count the records returned - something like:SELECT Count(*)FROM EXEC up_SelectRecs @ProductNameAny way to achieve this?Thanks all--James
hello, i have a stored procedure SELECT CommentID, UserName, CommentingDate FROM Comm WHERE PictureID = @PictureID ORDER BY CommentingDate DESC witch shows me the users who commented a Picture with PictureID = x I need to add two rows at that stored procedure, one to show the number of total comments at that picutre (like counting the number of rows returned) and the second to show count the DISTINCT users who commented that picture I tryied with COUNT but i have to use GROUP BY and i don't think this is good... I hope you understand... please help me, thanks
I I have a GridView with paging enabled which is bound to a SqlDataSource. I'd like to be able to tell the user how many records were returned in total by the SqlDataSource. Is there any way to do this without re-running the query?
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?
I have a strange problem. I have some code that executes a sql query. If I run the query in SQL server query analyzer, I get a set of data returned for me as expected. This is the query listed on lines 3 and 4. I just manually type it into query analyzer. Yet when I run the same query in my code, the result set is slightly different because it is missing some data. I am confused as to what is going on here. Basically to examine the sql result set returned, I write it out to an XML file. (See line 16). Why the data returned is different, I have no idea. Also writing it out to an XML file is the only way I can look at the data. Otherwise looking at it in the debugger is impossible, with the hundreds of tree nodes returned. If someone is able to help me figure this out, I would appreciate it. 1. public DataSet GetMarketList(string region, string marketRegion)2. {3. string sql = @"SELECT a.RealEstMarket FROM MarketMap a, RegionMap b " + 4."WHERE a.RegionCode = b.RegionCode"; 5. DataSet dsMarketList = new DataSet();6. SqlConnection sqlConn = new SqlConnection(intranetConnStr); 7. SqlCommand cmd = new SqlCommand(sql,sqlConn);8. sqlConn.Open();9. SqlDataAdapter adapter = new SqlDataAdapter(cmd); 10. try11. {12. adapter.Fill(dsMarketList); 13. String bling = adapter.SelectCommand.CommandText;//BRG 14. dsMarketList.DataSetName="RegionMarket"; 15. dsMarketList.Tables[0].TableName = "MarketList"; 16. dsMarketList.WriteXml(Server.MapPath ("myXMLFile.xml" )); // The data written to 17. myXMLFile.xml is not the same data that is returned when I run the query on line 3&4 18. // from the SQL query 19. } 20. catch(Exception e) 21. { 22. // Handle the exception (Code not shown)

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.

The following query returns a value of 0 for the unit percent when I do a count/subquery count. Is there a way to get the percent count using a subquery? Another section of the query using the sum() works.
Here is a test code snippet:
--Test Count/Count subquery
declare @Date datetime
set @date = '8/15/2007'
select -- count returns unit data Count(substring(m.PTNumber,3,3)) as PTCnt, -- count returns total for all units
(select Count(substring(m1.PTNumber,3,3))
from tblVGD1_Master m1
left join tblVGD1_ClassIII v1 on m1.SlotNum_ID = v1.SlotNum_ID
Where left(m1.PTNumber,2) = 'PT' and m1.Denom_ID <> 9
and v1.Act = 1 and m1.Active = 1 and v1.MnyPlyd <> 0
and not (v1.MnyPlyd = v1.MnyWon and v1.ActWin = 0)
and v1.[Date] between DateAdd(dd,-90,@Date) and @Date) as TotalCnt, -- attempting to calculate the percent by PTCnt/TotalCnt returns 0 (Count(substring(m.PTNumber,3,3)) /
(select Count(substring(m1.PTNumber,3,3))
from tblVGD1_Master m1
left join tblVGD1_ClassIII v1 on m1.SlotNum_ID = v1.SlotNum_ID
Where left(m1.PTNumber,2) = 'PT' and m1.Denom_ID <> 9
and v1.Act = 1 and m1.Active = 1 and v1.MnyPlyd <> 0

Stored Procedure:CREATE PROCEDURE [dbo].[GetBanner] @BannerPage nvarchar(50), @MagazineID intASBEGIN SET NOCOUNT ON; DECLARE @BannerID int SELECT TOP 1 @BannerID = BannerID FROM Banners WHERE BannerPage=@BannerPage AND MagazineID = @MagazineID AND StartDate <= GetDate() AND EndDate >=GetDate() ORDER BY Views SELECT BannerID, BannerFileName, AltText, URL, Views FROM Banners WHERE BannerID = @BannerID UPDATE Banners SET Views = Views +1 WHERE BannerID = @BannerID UPDATE BannerStats SET Views = Views + 1 WHERE BannerID = @BannerIDEND OnSelected method: protected void dsBanner_Selected(object sender, SqlDataSourceStatusEventArgs e) { int RecordCount = e.AffectedRows; Response.Write(RecordCount); } This ALWAYS gives me 0 - despite the fact that the correct banner is pulled from the database, and updated etc. Also, when I execute the procedure (for valid parameter values) in SSMS, I get "1 row(s) Affected". Can anyone tell me what I need to change to get the proper value? Thanks

I have a table that COULD be linked to 3 other tables, but if one of the link fields is zero I get nothing back at all. Here is my query: SELECTEvents.*, Agencies.A_NAME AS A_NAME, (Families.F_FNAME + ' ' + Families.F_LNAME) AS F_NAME, (Candidates.C_FNAME + ' ' + Candidates.C_LNAME) AS C_NAME FROM Events INNER JOIN Agencies ON Events.E_AGENCY_ID = Agencies.A_ID INNER JOIN Families ON Events.E_FAMILY_ID = Families.F_ID INNER JOIN Candidates ON Events.E_CANDIDATE_ID = Candidates.C_ID WHEREE_ID = 89
Even if all the inner join id's are zero, I would at least like to get back the event information. Could anyone help me out here, or do I have to do 4 queries?
The following sproc returns no records in query analyzer, although it doesn't error out either. Last time adding the length to the end of the variable fixed this problem, but this time it's an integer type which doesn't accept a length. Any ideas?
