I am using the SqlDataSource to access the dB from my page. Basically this is what I do with it ds.SelectParameters.Clear();
ds.SelectParameters("Id", TypeCode.Int32, id.ToString());
DataSourceSelectArguments dssa = new DataSourceSelectArguments();
dssa.MaximumRows = 1;
dssa.AddSupportedCapabilities(DataSourceCapabilities.Page);
DataView dv = (DataView)ds.Select(dssa);
if (dv.Count > 0)
{
// collect the information
string title = (string)dv[index].Row.ItemArray[0];
}
And the SelectCommand attribute of the SqlDataSource is set in design mode to "SELECT * from vw_Items ORDER BY Category".
So, since I am trying to retrieve just the item with the given Id I was expecting just one record but when I step through I see that the data view has a count of 9 (all records in the table) !!!
What am I doing wrong here? why can't it return just one? as per the select statement which after adding the parameter should be something like "SELECT * FROM vw_Items WHERE ID = 5 ORDER BY Category
I am running into an issue trying to declaratively set up a SqlDataSource. I want to be able to filter some of my queries based on the user that is currently logged into the web site. I want to do it Declaratively as that's one of my favorite 2.0 features.Is there any way to do this with the Membership information? I know I can use the code behind to set the parameter, or store the User Name in Session Variable, and use a <asp:SessionParameter> but I think there should be a way to bind directly to the Membership user...Am I missing another option, or is there no built in way to do this? Any other suggestions...Thanks
So I have this query that is ignoring my date filter and for the life of me I can't figure out why. Was hoping some guru could explain it to me. Here goes:
This query ignores my date filter:
SELECT rcv.Name AS MachineName, r.JobId, j.Name AS JobName, r.CreateTime AS JCreateTime, rsv.Name AS JResultStatus, rpv.Path + rpv.Name AS ResourcePool, rcvv.ResourceConfigurationVal AS Dimension
FROM dbo.Result_View AS r INNER JOIN dbo.ResourceConfiguration_View AS rcv ON r.ResourceConfigurationId = rcv.Id INNER JOIN dbo.Job_View AS j ON r.JobId = j.Id INNER JOIN dbo.ResultStatus_View AS rsv ON r.ResultStatusId = rsv.Id INNER JOIN dbo.Resource_View AS rv ON rcv.ResourceId = rv.Id INNER JOIN dbo.ResourcePool_View AS rpv ON rv.ResourcePoolId = rpv.Id RIGHT JOIN dbo.ResourceConfigurationValue_View AS rcvv ON rv.LatestResourceConfigurationId = rcvv.ResourceConfigurationId LEFT JOIN dbo.Dimension_View AS d ON rcvv.DimensionId = d.Id
WHERE (r.CreateTime > DATEADD(DAY, -15, GETDATE())) AND (rcv.Name LIKE 'PNP%') AND (d.Id = 859) OR (d.Id = 860)
If I comment out the last two joins and associated select/filters, all of the sudden the date filter works again. From everything I have read, the joins are supposed to be processed BEFORE the filters are applied in the virtual table. My DB goes back a number of years and contains millions of records. W/O the date filter, the query takes a very, very long time to run.
I use SQL Server 2005. I have approx. 50 tables in my database and 30 of them have a filed named "CompanyID". Example: create table A (ID int identity, NAME varchar(100), COMPANYID int)create table A (ID int identity, REF_ID int, FIELD1 varchar(100), FIELD2 varchar(100), COMPANYID int)
Also there are nearly 200 stored procedures that read data from these tables. Example: create procedure ABCasbegin /* some checks and expressions here ... */ select ... from A inner join B on (A.ID = B.REF_ID) where ... /* ... */end;
All my queries in the Stored procedure does not filter the tables by CompanyID, so they process the entire data.
However, now we have a requirement to separate the data for each company. That means that we have to put a filter by CompanyID to each of those 20 tables in each query where the tables appear.
Firstly, I put the CompanyID in the context so now its value is accessible through the context_info() function. Thus I do not need now to pass it as a parameter to the stored procedures.
However, I don't know what is the easiest and fastest way to filter the tables. Example:
I modified the above mentioned procedure in the following way: create procedure ABCasbegin /* some checks and expressions here ... */ -- gets the CompanyID from the context: DECLARE @CompanyID int; SELECT @CompanyID = CONVERT(float, CONVERT(varchar(128), context_info())) select ... from A inner join B on (A.ID = B.REF_ID) where ... and A.COMPANYID = @CompanyID and B.COMPANYID = @CompanyID /* ... */end;
Now I have the desired filter by CompanyID. However, modifying over 200 stored procedures is rather tedious work and I don't think that this is the best approach. Is there any functionality in SQL Server that can provide the possibility to put an automatic filter to the tables. For example: when I wrote "SELECT * FROM A", the actual statements to be executed would be "SELECT * FROM A WHERE CompanyID = CONVERT(float, CONVERT(varchar(128), context_info()))".
I was looking for something like "INSTEAD OF SELECT" triggers but I didn't manage to find any answer.
I would very grateful is someone suggests a solution for something like "global table filter" (that will help me make an easy refactoring)?
Hi, I am new in framework 2 and I can't find a way to filter the sqldatasource. I have an sqldatasource control that retrive data from data base-"Select * from myTable" I set the fiterExpression property-sqlDataSource1.FilterExpression="ID='" + strID + "' " ; I don't know how to continue from here.If I bound the sqlDataSource1 to a control like gridView it works good and I see the filter oparation. but I want to get the result set in the code and loop threw it like I did with ver 1.1 with sqldataReader: While sqlDatareader1.Read { myCode ... } How can I do it with sqlDataSource ? Thanks, David

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.
I want to create a stored procedure that returns a list of records froma table. But depending on a userID value given only certain recordswill be returned that they have access to.I think this might be hard to do in a single SELECT statement becausethe user might also belong to a group that might have permission, etc.Can you do something like this pseudo code in a T-SQL procedure?DECLARE cur CURSOR FOR SELECT * FROM myTableOPEN curFETCH NEXT FROM curWHILE @@FETCH_STATUS = 0BEGINif( accessGranted(curRecord.id) ){ addRecordToResultSet() }else { ommitRecordFromResultSet() }END
I would like to ask for a help regarding MDX query.
I am developing reports in SSRS 2005 that use some multi-valued parameters. I need to filter out my data according to the dimension's properties' value
For example, if I have only single value parameters, I would do:
SET [SelectedDestination] AS FILTER( [Country].[Destination].Members, [Country].CurrentMember.Properties("KEY") = Parameters!Country.Value)
However, I have no idea how to handle it if Parameters!Country is a multi-valued parameter.
Is there a better method to do this? Would anybody please kindly give a direction? it will be greatly appreciated!! any help will do..
Is it possible to set a filter in the SELECT-statementpart? Normaly you the filter is set in the WHERE-statementpart, but that is too late for me in my statement. Right after the SELECTing the field I want to set a filter to the query? Is it possible?
My statement looks like this now: SELECT [DatabaseName$Item].No_, [DatabaseName$Item].Description, [DatabaseName$Sales Price HAG].[Unit Price], [DatabaseName$Sales Price HAG].[Starting Date], [DatabaseName$Sales Price HAG].[Starting Time], [DatabaseName$Sales Price HAG].[Sales Code] (<== here on this item I want to set a filter)

Hi all,I drag sqldatasource to my form, and then adding a button there. I want when clicking the button to be able to use the sqldatasource1.select statement . I found some parameters that this method used but still dont know how to figure it out, which was IEnumerable Select (DataSourceSelectArguments a)for example when the button it clicked I want to perform the select * from employee Thanks
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?
(Newbie). I'm trying to: 1) check if the SELECT command has returned any records, and 2) put a msg box on the screen if there are no records returned from the SELECT query. The type of code I'm heading towards is: (but it's wrong). Thank you in advance for your C# code suggestion. protected void SqlDataSource1_Selected(object sender, SqlDataSourceStatusEventArgs e) {if (SqlDataSource1.SelectParameters.Contains is "") then MessageBox.show ("There are no records available") ; }
I'm sure that is really simple, but how do I pass a parameter with multiple value to a SQLdatasource? ex: SELECT field1 from tblTableA where idTableA IN ( @Param1) Let's say I want to pass 1,2,3,4 as Param1 (SELECT field1 from tblTableA where idTableA IN ( 1,2,3,4)) How I am supposed tu use the .SelectParameters.Add() to pass a list of integers instead of a single value?? Thanks in advance.
I am using <asp:SqlDataSource ID and for the Select Command, the following, where the WHERE clause ... for an exact match (=) works correctly: SelectCommand="SELECT [PatientID], [MedRecord] , [Accession], [FirstName], [LastName], [Address1] FROM [ClinicalPatient] WHERE (LastName = @LastName) ORDER BY [LastName]DESC"> I would like to do a "LIKE" search where the LastName Parameter is matched using "LIKE". In this situation how would the syntax be written.... I tried: LastName LIKE '%" & LastName & "%'" But I get an error???? Any suggestions, please... Thanks !!
I have a SqlDataSource object that is bound to a GridView control. I have configured the SqlDataSource with a default select command. Under certain values of query strings on the URL for this page (Default.aspx), I want to change the select command. So I put the statements in the Page_Load method for Default.aspx to define SqlDataSource1.SelectCommand. The changed SelectCommand works fine for the first page of GridView data and shows 5 GridView pages, but if I switch to one of the other pages, it seems to revert to the default SelectCommand (which generates 19 GridView pages). I assume I should put my code to change the SelectCommand somewhere else. Can someone help me with where to put it? Thanks!
Is it possible to use a WHERE-IN statement with a SqlDataSource control. For instance: <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:myConnectionString %>" SelectCommand="SELECT [Id], [Name], [Phone] FROM [Table1] WHERE ([Id] IN @Id)"> <SelectParameters> <asp:Parameter DefaultValue="( 1, 3, 5, 7, 11 )" Name="Id" Type="Int32" /> </SelectParameters></asp:SqlDataSource> I'm hoping the gridview would then display a table with rows for records 1,3,5,7,11. Thanks for any help...

I have a GridView (that uses SqlDataSource1) and a Dropdownlist. Depending upon the value selected on the DropDownList I need to select different stored procedures for the gridview. The problem is that I can do it without taking SqlDataSource1 by using DataSet or DataTable. But, I need to Use SQLDataSource1 for easy way of Header SORTING. So, is there any way to change the SQLDatasource1.SELECT Command dynamically. So that, I can use different queries for the Single DataGrid. I have attached the sample code of the SqlDataSource1 I'm using. I need to change the Command i.e. SelectCommand="usp_reports_shortages" to "usp_reports_shortagesbyID" and "usp_reports_shortagesbyDate" depending on the value selected in the dropdownlist. So, is there any way to do this????<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:TESTDrivercommunication %>"
I'm a traditional asp guy and I'm having a heck of a time getting my arms around this SQLDataSource provided in ASP.NET 2.0 I've setup the Connection String and successfully used the SQLDataSource.Insert method. I can't for the life of me figure out how to use the SQLDataSource.Select command. I want to get the @@IDENTITY of the last record inserted. Example: ---Works Fine--- SQLDataSource.InsertCommand = "Insert into Engines(Type, Description)values('" & DrpType.Text & "', '" & txtDescription.Text & "')" SQLDataSource.Insert() --- End Works Fine------- Doesn't Work--- SQLDataSource.SelectCommand = "Select @@IDENTITY as 'Identity'" set RecordSetVar = SQLDataSource.Select <--- this wants some kind of arguements --- End Doesn't Work---
I am trying to implement an "advanced search" feature on my ASP.NET 2.0 web form. I have a GridView control and a SqlDataSource. The SqlDataSource control successfully retrieves data when the SelectCommand attribute is set in the aspx page. I need to make it so when a user clicks on a button, it can take a value from a text box and use it in the WHERE clause. I have tried setting the SelectCommand programmatically and then DataBinding but it never accepts the new SelectCommand. What can I do to fix this?
Hello, I am trying to write a select command that will select a table by year using asp:sqldatasource selectcommand. The table name includes the year, ie: table98, table99, table00, table01, etc. These tables do not have a 'year' field but there is a separate table called "Years" where each record is a different year. In other words, my select statement is static where is needs to be dynamic. Not sure if that makes sense, but any help would be great!!!
I cant seen to change the Select command for a SQL Datasourcetry #1 SqlDataSourceProfilesThatMatch.SelectCommand = strSQLForSearch SqlDataSourceProfilesThatMatch.SelectParameters("ProfileID").DefaultValue = pProfileID SqlDataSourceProfilesThatMatch.SelectParameters("LoggedInUsersZipcode").DefaultValue = pUsersZipCode SqlDataSourceProfilesThatMatch.SelectParameters("ZipDistance").DefaultValue = pDistance NewProfilesThatMatchGridView.DataBind() try #2 SqlDataSourceProfilesToBeMatched.SelectParameters.Clear() SqlDataSourceProfilesThatMatch.SelectCommand = strSQLForSearch SqlDataSourceProfilesThatMatch.SelectParameters.Add("ProfileID", pProfileID) SqlDataSourceProfilesThatMatch.SelectParameters.Add("LoggedInUsersZipcode", pUsersZipCode) SqlDataSourceProfilesThatMatch.SelectParameters.Add("ZipDistance", pDistance) NewProfilesThatMatchGridView.DataBind() No errors but no rows show in the gridview. If I debug and get the value strSQLForSearch and paste it into a new SQL query window I get results. Any ideas???? Thanks
