I have a label on my page that shows a persons name, but in the database it is identified by a ID for indexing purposes. When I do a UPDATE (users can change other info on the page...not the name though), I want to update by the ID, not the actual name. Problem is, I don't have the ID (just the name) on the page, so I would have to do a lookup for the ID in the database. Is there a another way to do this? When I select the persons name for display using the SqlDataSource, it's easy to select the ID too. But how can I use this ID on the UPDATE? I don't want to reinvent the wheel.
I have the following:omegalove.comIf you go to the search portion u will notice that there are three dropdownlist that are populate using sqldatasource object.I do not want these two post back. Is there a way we can cache this so it is faster.I would like to learn. I appreciate any help. Please don't give me links. I much rather learn from someone who has hands on.Thank you I will have to separate the code from the ui?--------------------------------------------------------------------- Country:<asp:Image ID="FlagImg" runat="server" Height="12px" Width="20px" />
Hi all,Is there a way of counting the number of results/rows from an SqlDataSource which uses a select statement like: "SELECT * FROM TABLE1". I need to get this value from the SqlDataSource into the Sub Page_Load. I don't want to bind to any gridviews, repeaters etc. I just want to get the number of rows/results from the SqlDataSource.Is there a way of doing this?Thanks
Hi guys, now i was able to get the results of the query i made. and the remaining problem now is how can i store the results to my database? here's the my code: protected void btnGenerate_Click(object sender, EventArgs e) { _con = new SqlConnection(database.evgConnection()); _comm = new SqlCommand("EV_usp_SearchNoticeLocation", _con); _comm.CommandType = CommandType.StoredProcedure; _comm.Parameters.AddWithValue("@Locationid", ddlLocation.SelectedValue); _adapt = new SqlDataAdapter(_comm); DataSet objDataset = new DataSet(); _adapt.Fill(objDataset); GridView1.DataSource = objDataset; GridView1.DataBind(); foreach(DataRow dr in objDataset.Tables[0].Rows) { Response.Write(dr["Docownerid"].ToString()); } } how can i store all the Docownerid to another database table?
Can anyone tell me or point me in the direction of how I can store select query results to a variable in VB.NET? Im using the SqlDataSource control with dropdowns and textboxes for searching. I want to store the search results in a variable on the button click event.
I'm writing a search engine and I want to make a search and then, after I've recieved the results, put them into some sort of temporary(in mememory) table so that I can do another query on that temporary table.
I saw something about temp tables (in T-SQL) in the help guide, but I still want to know how to do a query on a regular table and then store those results in a temporary table to perform a query on that. Could anyone show me some example or something?
I thought I would impliment a new feature of my web page using stored procedures and the SqlDataSource object, for practice or whatever, since I don't normally use that stuff. This is the stored procedure:set ANSI_NULLS ON set QUOTED_IDENTIFIER ON go
ALTER PROCEDURE [dbo].[AppcheckContest] -- Add the parameters for the stored procedure here
@BeginDate datetime = '1/1/2006', @EndDate datetime = '12/31/2006', @SectionID int = 10, @WinnerID int = 0 OUTPUT AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements.
SET NOCOUNT ON;
-- Insert statements for procedure here
SELECT top 1 @WinnerID = P.UserID FROM cs_Posts P WHERE P.PostDate BETWEEN @BeginDate AND @EndDate AND P.SectionID = @SectionID AND P.UserID <> 2100 -- I don't want to win my own contest...
AND SettingsID = 1000 -- This number could be different if i had more than one CS installed?
AND IsApproved = 1 ORDER BY NEWID() -- yes this is slow, but it works...
RETURN @WinnerID END It's really simple - just needs to return the one randomly chosen integer userID. I've tested it in query designer or whatever it's called in Management Studio and it works fine there at least. Thinking I was done the hard part, I created a new web form in visual studio, dropped a SqlDataSource on it, and used the 'configure data source' wizard from the smart tag to do all the work for me. I didn't have any trouble using the wizard to select my stored procedure, and i'm using the sa connection string to simplify my debugging. I tried using the FormParameter / FormField way of getting the output and setting the input parameters. I can't seem to get it working though. There's no errors or anything, just the output isn't coming through. Here's the code from the aspx codebehind file:Partial Class Contest Inherits System.Web.UI.Page
Protected Sub btnSelectWinner_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSelectWinner.Click Dim stuff As New System.Web.UI.DataSourceSelectArguments SqlDataSource1.Select(stuff) SqlDataSource1.DataBind() lblWinnerID.Text = SqlDataSource1.SelectParameters("WinnerID").ToString End Sub End Class As you can see, I wasn't sure if you're supposed to call databind() or select() to actually get the stored procedure to execute, so I tried both. I was hoping the last line of code there would set the label to the value contained in the @WinnerID parameter, but instead it sets it to "WinnerID". Here's the code from the .aspx file. Most of this was generated by the Wizard, but I messed around with it a bit. <%@ Page Language="VB" MasterPageFile="~/MasterPage.master" AutoEventWireup="false" CodeFile="Contest.aspx.vb" Inherits="Contest" title="Untitled Page" %> <asp:Content ID="Content1" ContentPlaceHolderID="CPHMain" Runat="Server"> <asp:Button ID="btnSelectWinner" runat="server" Text="Find Winner" /> <asp:Calendar ID="Calendar_From" runat="server"></asp:Calendar> <asp:Calendar ID="Calendar_To" runat="server"></asp:Calendar> <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:appcheck-csConnectionString-sa %>" SelectCommand="AppcheckContest" SelectCommandType="StoredProcedure" CancelSelectOnNullParameter="False"> <SelectParameters> <asp:FormParameter FormField="Calendar_From" Name="BeginDate" Type="DateTime" /> <asp:FormParameter FormField="Calendar_To" Name="EndDate" Type="DateTime" /> <asp:Parameter DefaultValue="10" Name="SectionID" Type="Int32" /> <asp:formParameter FormField="lblWinnerID" defaultvalue="666" Direction="InputOutput" Name="WinnerID" Type="Int32" /> </SelectParameters> </asp:SqlDataSource>
I would like to perform a large query operation (which takes many seconds), and store that into a designated table which will act as basically a cache for that query. Is there a way to achieve this just using SQL, as opposed to using a data reader, then inserting that back into the designated table with a sqlceresultset.
I have a query that I created in SqlServer and then merely copied the code to a sqldatasource. They are both connected to the same db, however the sqldatasource query only returns 6 records and when run in SqlServer, it returns 52 rows which is the correct number. Any ideas on what might be causing this? There are no filters on the sqldatasource. It only has that one query. Do they differ in the way they execute sql code? Thanks for any help!
Hi, Hope you guys won't mind this rather newbie question. I'm writing a simple blog page for my website and have created a SqlDataSource which queries the database for a list of blog post titles (from the web.Blog table) and the number of comments (from the web.BlogComments table). The SqlDataSource control is: <asp:SqlDataSource ID="sourceBlogArticles" ProviderName="System.Data.SqlClient" connectionString="<%$ ConnectionStrings:myDatabase %>" runat="server" SelectCommand="SELECT gb.blogID, gb.title, gb.description, gb.tags, gb.dateAdded, COUNT(gbc.blogID) AS noOfComments FROM web.Blog gb LEFT OUTER JOIN web.BlogComments gbc ON gb.blogID = gbc.blogID GROUP BY gb.blogID, gb.title, gb.description, gb.tags, gb.dateAdded ORDER BY gb.dateAdded"></asp:SqlDataSource> This works perfectly well if each blog entry in the web.Blog table has associated comments in the web.BlogComments table. However, if there are no comments yet defined in the web.BlogComments table for that blogID then no row is returned in ASP.Net (as checked with a GridView control or similar linked to the data source to view what I get) HOWEVER, I think the SELECT command IS correct: if I use the select command as a query in SQL Server Managment Studio Express, I do get the rows returned, with 0 for the number of comments which is what I would expect for that query: blogID, title, description, tags, dateAdded, noOfComments 1, title 1, description for title 1, tag1, 2007-09-27 06:49:03.810, 32, title 2, description for title 2, tag2, 2007-09-27 06:49:37.513, 03, title 3, description for title3, tag3, 2007-10-02 18:21:30.467, 0 Can anyone help? The result from the SSMSE query is what I want, yet when I use the very same SELECT statement in my SqlDataSource I don't get any rows returned if the BlogComment count is zero (in the above example I get only the first row). Many thanks for any suggestions!
I am looking for an example of a store procedure that will run a existing view and copy the results to a table. Every time it runs the table needs to be truncated. Will run once a day.
My view is a follows
SELECT PClass FROM mydatabase.dbo.ProductClassDes WHERE (ProductClass <> '_RBS') AND (ProductClass <> '_EDT') AND (ProductClass <> '_BMS') AND (ProductClass <> '_PAZ') AND (ProductClass <> '_PBC')
View results need to be copied to a table tblCurrentProductClasses that will only contain one field PClass.
I am wondering if tempdb stores all results tempararily whenever I query a large fact table with over 4 million records which joins another dimension table? Since each time when I run the query, the tempdb grows to nearly 1GB which nearly runs out all the space on my local system drive, as a result the performance totally down. Is there any way to fix this problem? Thanks a lot in advance and I am looking forward to hearing from you shortly for your kind advices.
I am wondering where can I store my mining results in data mining engine? For example, I got mining results like accuracy chart, decision trees, and other formats of results based on different mining algorithms I used for my data mining, so where can I actually store the results for reporting service use later? Is it possible to do that in SQL Server 2005?
Thanks a lot for any help and guidance in advance.
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, like, if i need to do delete some items with the id = 10000 then also need to update on the remaining items on the with the same idthen i will need to go through all the records to fetch the items with the same id right? so, is there something that i can use to hold those records so that i can do the delete and update just on those records and don't need to query twice? or is there a way to do that in one go ?thanks in advance!
I have four tables: Customer (CustomerId INT, CountyId INT), County (CountyId INT), Search(SearchId INT), and SearchCriteria (SearchCriteriaId INT, SearchId INT, CountyId INT, [others not related to this]).
I want to search Customer based off of the Search record, which could have multiple SearchCriteria records. However, if there aren't any SearchCriteria records with CountyId populated for a given Search, I want it to assume to get all Customer records, regardless of CountyId.
Right now, I'm doing it this way.
DECLARE @SearchId INT = 100 SELECT * FROM Customer WHERE CountyId IN ( SELECT CASE WHEN EXISTS(SELECT CountyId FROM SearchCriteria WHERE SearchId = @SearchId) THEN SearchCriteria.CountyId
[Code] .....
This works; it just seems cludgy. Is there a more elegant way to do this?
Hello. I currently have a website that has a table on one webpage. When a record is clicked, the primary key of that record is transfered in the query string to another page and fed into an sql statement. In this case its selecting a project on the first page, and displaying all the scripts for that project on another page. I also have an additional dropdownlist on the second page that i use to filter the scripts by an attribute called 'testdomain'. At present this works to an extent. When i click a project, i am navigated to the scripts page which is empty except for the dropdownlist. i then select a 'testdomain' from the dropdownlist and the page populates with scripts (formview) for the particular test domain. what i would like is for all the scripts to be displayed using the formview in the first instance when the user arrives at the second page. from there, they can then filter the scripts using the dropdownlist. My current SQL statement is as follows. SelectCommand="SELECT * FROM [TestScript] WHERE (([ProjectID] = @ProjectID) AND ([TestDomain] = @TestDomain))" So what is happening is when testdomain = a null value, it does not select any scripts. Is there a way i can achieve the behaivour of the page as i outlined above? Any help would be appreciated. Thanks, James.

ErikGalvezMelville82625180.7200000.7307691.24000011322101015 As you can see, all teams except for Safe Haven's have the correct AVG and OBP. Since AVG is simply H/AB, it doesn't make sense for Gabriel Helbig's results to be 1.00000. Can anyone shed ANY light on this please?Thank you in advance,Markuu ***As a side note, could anyone also let me know how I could format the output so that AVG and OBP are only 3 decimal places? (ex: 0.719 for the 1st result)***
Hi, I have a web form that lets users search for people in my database they wish to contact. The database returns a paged set of results using a CTE, Top X, and Row_number(). I would like to give my users to option of removing individual people from this list but cannot find a way to do this. I have tried creating a session variable with a comma delimited list of ID's that I pass to my sproc and use in a NOT IN() statement. But I keep getting a "Input string was not in a correct format." Error Message. Is there any way to do this? I am still new to stored procedures so any advice would be helpful. Thanks
Hi, when I copy and paste results from query analyzer into Excel it appears that values with zeroes at the end loose the zeroes. Example, if I copy and paste V128.0 into an Excel cell it comes out as V128 or if I copy 178.70 it displays as 178.7 - any ideas? I'm using SQL Enterprise Manager for 2000.

hi all, in all my 2.0 learnings and books i keep coming across the page element <asp:sqldatasource>. I have always (in 1.1) used server side connections and adapters to bind my Sql datasets to any control needed. Now that im learning 2.0 im finding it difficult to understand using control on the page to bind my data. Can someone explain the benefits of using this data source? Ideally i would like to keep my data access layer separate from my presentation layer but i'd really like to understand why this method seems so popular. thanks in advance, mcm
Hi, I am new to ASP.NET 2.0 and I am trying to use VWB to bind my web site to a SQL Express edition. I used SQLDataSource to specify the .mdf file so I can connect to my tables but when I click on the advanced button to generate the Insert, Update, Delete SQL I find it grayed out and it cannot be clicked. I looked into several tutorials online and I couldn't find the problem, can anyone explain what I am missing or doing wrong? Any suggestion is very appreciated. Thanks
