Sqldatasource Using Session Data In Select Parameters
Jan 12, 2007
I'm having trouble using session data in my select parameters. If I manually plug a value into the selectcommand or create a hard coded value using a parameter it works, but if I try to use the session data the query pulls no results. I know the session data is set because I print the value at the top of the page, but for some reason it's not getting passed to the sessionparameter???
This is the datasource code:
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:flautoconnstr %>"
SelectCommand="SELECT * FROM [tblVehicles] WHERE ([profileid] = @profileid)">
<SelectParameters>
<asp:SessionParameter Name="profileid" SessionField="profileid" Type="String" />
</SelectParameters>
</asp:SqlDataSource>
This is the line I use to set the session data.
Session["profileid"] = myQuote.Profileid;

Is there a way to retreive the SQL Statement with the values from the parameters merged together? I know how to retreive the SQL Select Statement and the parameters separately but I need to retreive the final SQL.
For example:
SELECT name FROM employee WHERE id = @id
I would like to retreive from SQLDataSource
SELECT name FROM employee WHERE id = 1
Thank you

I have a sqldatasource in a wizard. When I click the finishbutton in the wizard I want to insert some values (from textboxes, dropdownlists in my wizard) into a mysql-database. For this I use parameters, I add some values in the design mode and some in codebehind. The parameters in codebehind are added perfectly but the other parameters in designmode (name, email) just inserts null. Why? My datasource: <asp:SqlDataSource
ID="dsInsert"
InsertCommand="INSERT INTO tbltest (name, email, city) VALUES (?name, ?email, ?city)"
runat="server"
ConnectionString="<%$ ConnectionStrings:conn %>"
ProviderName="MySql.Data.MySqlClient">
<InsertParameters>
<asp:FormParameter Name="?name" ConvertEmptyStringToNull="true" Type="string" FormField="name" />
<asp:FormParameter Name="?email" ConvertEmptyStringToNull="true" Type="string" FormField="email" />
</InsertParameters>
</asp:SqlDataSource> The codebehind: protected void finishButtonClick(object sender, EventArgs e) { dsInsert.InsertParameters.Add("?city", TypeCode.Int32, city.SelectedValue); dsInsert.Insert(); }

I have a Gridview bound to a SQLDataSource that uses a Stored Procedure expecting 1 or 2 parameters. The parameters are bound to textbox controls. The SP looks up a person by name, the textboxes are Last Name, First Name. It will handle last name only (ie. pass @ln ='Jones' and @fn=null and you get all the people with last name=Jones. I tested the SP in Management Studio and it works as expected. When I enter a last name in the Last Name textbox and no First Name I get no results. If I enter a Last Name AND First Name I get results. I don't understand.
Here's the HTML View of the page. The only code is to bind the Gridview when the Search button is pressed.

Hi Everyone,
I set the session("MyTable") with the user's name as contents when the user logs in, then I copy a new table name with session("MyTable") , I set PK and this all works, but I can't seem to figure out how to use the session var as table name SQLDataSource Selectcommand? I try a bunch of different stuff, putting it into a key in the web.config. Seems like this should be a piece of cake.
Im getting ~ "Session variable is not a valid datasource item" etc. Below is one of the things I have tried.<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:Connectio String %>" SelectCommand="Select * From [" + Session("MyTable") + "] Where ID = @ID">
TIA

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>

I'm having a real problem populating my SqlDataSource and was wondering if anyone could help. I'm sure it's something simple
First off, I created a session variable on a previous page like so Dim NewSubscribeID As Integer = Convert.ToInt32(retSubcribeID.Value)
Session("SubcribeID") = NewSubscribeID
I now want to use this session variable on another page to populate a SqlDataSource like so <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionXX %>" SelectCommand="spXX" SelectCommandType="StoredProcedure">
<SelectParameters>
<asp:SessionParameter Name="SubscribeID" SessionField="SubscribeID" Type="Int32" DefaultValue="0" />
</SelectParameters>
</asp:SqlDataSource>
Here is the problem... Only the default value gets used.
I've tried putting the session variable into a label to test that it does actually exist lblTest.Text = Session("SubcribeID")
and it does...What am I doing wrong?

I'm getting a type mismatch error (currently string, when I think I need Int32 ?) with the code below. I'm having difficultly setting my session variable to type Int32 and having it take up the value of RawCoDeptRowID. When I "Watch" it, it's value remains as "snCoDeptRowID". Also, not sure if my Update command and it's snCoDeptRowID input parameter is well formed? Any advice would be greatly appreciated. Thank you.
Web Page 1:
Session["snCoDeptRowID"] = Convert.ToInt32 (RawCoDeptRowID);
Web Page2:<asp:SqlDataSource ID="SqlDataSource3" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
UpdateCommand="UPDATE [CompanyDepartment] SET [User_Name] = @User_Name, [FirstName] = @FirstName, [LastName] = @LastName, [Company_Name] = @Company_Name, [Department_Name] = @Department_Name WHERE [User_ID] = @snCoDeptRowID ">
<updateparameters>
<asp:parameter Name="User_Name" Type="String" />
<asp:parameter Name="FirstName" Type="String" />
<asp:parameter Name="LastName" Type="String" />
<asp:Controlparameter Name="Company_Name" Type="String" ControlID ="ListBox1" PropertyName ="SelectedValue" />

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---

Hi all,
This is probably one of the easier questions you get, but I have brain freeze and just can't do it and very rusty.
How can i assign the the values from sql below into variables e.g I want to get all new, pending and cancelled Leads from the rows returned which will come from the status id.
SELECT Count (leadStatusId) As NoOfLeads, leadStatusID, sum(value) As Value
FROM [dbo].[tLead] L
Inner Join dbo.tLeadStatus S on linkLeadStatus = LeadStatusID
Inner Join dbo.tClick C on linkClick = ClickID
WHERE L.DateDeleted Is NULL AND linkAffiliateUser = @UserID AND Month(L.DateCreated) = @month And Year (L.DateCreated) = @Year
Group by LeadStatusID
Order by LeadStatusID asc

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.

Since I had a bad error in replication, my replication monitor won't show the tab "Error details or messages of the select session".
I am not able to activate or to show this "tab", to get all information about my error.
I added two screeshots, one with the 3 tab, and the other, were the information about my error are missing. How i can my default view back?
Replication Monitor OK:

Is
it possible to specify different parameters for the
select/update/delete stored procedures used by a sqldatasource? When I
'configure the datasource' it lists the different stored procedures for
each command, but when it comes to specifying the parameters it only
lets me do so for the select command. Is there another way to do this
for the other commands?
I have tried doing it manually in the aspx file (using the
DeleteParemeters etc), but I don't know how to reference a specific
cell in the selected row of the gridview for the controlparameter). Any
thoughts?

Hello I need help withsetting parameters for SqlDataSource
I have a simple program. I want display date from database on MS SQLSERVER from the table USERS only for current sing on user select by his login.
I save into this variable login current user: string @LOGIN = Context.User.Identity.Name;
I have already done with this way without SqlDataSource:
string login = Context.User.Identity.Name;
SqlConnection conn1 = new SqlConnection("server=CR\SQLEXPRESS;database=myData;integrated security=SSPI");
conn1.Open();
SqlCommand cmd1 = new SqlCommand(" SELECT IN_OUT.TIME_START, IN_OUT.TIME_END, FROM IN_OUT INNER JOIN USER ON USER.USER_ID=IN_OUT.RC_USER_ID where USER.LOGIN=@LOGIN", conn1);
cmd1.Parameters.Add("@LOGIN", SqlDbType.NVarChar, 50);
cmd1.Parameters["@LOGIN"].Value = login;
1.Parameters.Add("@LOGIN", SqlDbType.NVarChar, 50);
cmd1.Parameters["@LOGIN"].Value = login;
Now I don't know how to do with SqlDataSource, what I have to set in SqlDataSource1 yet
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:myConnectionString %>"
ProviderName="<%$ ConnectionStrings:myConnectionString.ProviderName %>" SelectCommand="SELECT IN_OUT.TIME_START, IN_OUT.TIME_END, FROM IN_OUT INNER JOIN USER ON USER.USER_ID=IN_OUT.RC_USER_ID where USER.LOGIN=@LOGIN">

I need to do some select & update from VB code behind a web page. Using VS2005, ASP.NET.
To me, the most logical approach would be to use a SqlDataSource. I can select the connection string, predefine select, insert and update queries and call the select(), and other commands from this control.
I need to use parameters in the queries but I cannot connect parameters straight to controls, I need to do it from VB. But nowhere can I find how to set the parameter values from code. I can find all kind of examples from VS2003 or using SqlCommand, but it should be possible from this control as well, but the help documentation is very poor in this respect.
Please provide me with some example.
Kind regards

Hi,How do I set the parameters of an SqlDataSource programatically?I have tried the following...dsDraftBudgetPI.SelectParameters.Add(new Parameter("@person_id", TypeCode.Int32, pID.ToString()));But that didn't work. I already have the parameter defined at design time so I don't need to create one I just want to set its value and then bind it to a ListBox to display the result.Thanks,Scott

Hello!
I am pulling my hair out over this latest problem. I'm trying to do a simple SQL SELECT statement by taking values from textboxes and inserting them into the WHERE part of the statement. I'm using MySQL and have to use ? prefix for all inserts, that I have working by the way. Now for some reason I cannot get the values from the text boxes to replace the prefixes! Here is my code:
private void submitLogin(object source, EventArgs e) {
if (isPassword(password.Text.ToString()) && isEmail(username.Text.ToString()))
{
ValidateCustomer.SelectParameters["c_email"].DefaultValue = "fish";
ValidateCustomer.SelectParameters["c_password"].DefaultValue = "cakes";
test_label.Text = ValidateCustomer.SelectCommand.ToString();
}
else {
test_label.Text = "Username or Password Incorrect";
}
}
<asp:SqlDataSource runat="server"
ID="ValidateCustomer"
ProviderName="System.Data.Odbc"
ConnectionString ="<%$ connectionStrings:MySQLDatabase %>"
SelectCommand ="SELECT * FROM customer_details WHERE (Customer_Email = ? AND Customer_Password = ?)">
<selectparameters>
<asp:parameter name="c_email" type="String" />
<asp:parameter name="c_password" type="String" />
</selectparameters>
</asp:SqlDataSource>
I have omitted obvious code. The test label, when updated, shows the SQL statement but with the ?. I also use controlparameters that took the values directly from the textboxes but again this did not work. I'm really stuck with this one. Your help is much needed!
Cheers
Dan

I have a GridView bound to a SqlDataSource. On page load I would like to programmatically specify a SelectParameter value based on the role of the user. This SelectParameter will be used in my WHERE clause. The closest post I can find is http://forums.asp.net/thread/1233258.aspx but no answer was posted.
What code would I use to modify a SelectParameters value? Is it possible to reference a parameter by name (SqlDataSource1.SelectParameters["usertype"]) or does it have to be by index? (SqlDataSource1.SelectParameters[0])
Alternatively, perhaps I'm going about this in the wrong way, is there a better way to have dynamic GridView content based on the role of the user?
Thank you very much for your help.

I'm passing a parameter to a stored procedure stored on my sqlserver, or trying to atleast. And then firing off the update command that contains that parameter from a button. But it's not changing my data on my server when I do so.
I'm filling a dropdown list from a stored procedure and I have a little loop run another sp that grabs what the selected value should be in the dropdown list when the page loads/refreshes. All this works fine, just not sp that should update my data when I hit the submit button.
It's supposed to update one of my tables to whatever the selected value is from my drop down list. But it doesn't even change anything. It just refreshes the page and goes back to the original value for my drop down list.
Just to make sure that it's my update command that's failing, I've even changed the back end data manually to a different value and on page load it shows the proper selected item that I changed the data to, etc. It just won't change the data from the page when I try to.
This is what the stored procedure looks like:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
ALTER PROCEDURE [dbo].[UPDATE_sp] (@SelectedID int) AS
BEGIN
UPDATE [Current_tbl]
SET ID = @SelectedID
WHERE PrimID = '1'
END

<SelectParameters>
<asp:Parameter Name="accountTypeName" Type="string" />
</SelectParameters>

I would like expenseaccount to be able to specify "EXPENSE", incomeaccount to specify "INCOME", etc...

I am using a SQLDataSource with Stored Procedures. The Select, Insert and Update all work well. However I cannot get the delete to work. My stored procedures are tested and verified and the parameter names are the same as the source columns. When I try to run the delete an error that the stored procedure expects the parameter @locationStationId, however this value passes properly for the Update command?!? I tried to change the parameter to original_locationStationID to pass the original value, however this result in Null being passed for the parameter.
I cannot understand why this works for Update and passes the location ID, but will not work for DELETE. Can anyone shed any light onto the matter?
Thanks.OldValuesParameterFormatString="original_{0}" UpdateCommand="spUpdateLocation" UpdateCommandType="StoredProcedure"
DeleteCommand="spDeleteLocation" DeleteCommandType="StoredProcedure">
<DeleteParameters>
<asp:Parameter Name="locationStationId" Type="String" />
</DeleteParameters>
<InsertParameters>
<asp:Parameter Name="locationStationId" Type="String" />
<asp:Parameter Name="locationType" Type="String" />
<asp:Parameter Name="locationName" />
<asp:Parameter Name="division" Type="String" />
</InsertParameters>

I have an SQLDataSource. The SQL is
SELECT UserName, Category, ItemDescription, Size, Price, Reduce, Donate, Sold, ItemNumber, SoldDate, SoldPrice, PrintedFROM Tags WHERE (Printed = @Printed1 OR Printed = @Printed2 OR Printed = @Printed3) ORDER BY ItemNumber DESCThe bit field "printed" can be NULL, True or False.In the Selecting event of the SQLDataSource I have the following to show ALL records. But it does not work. If I remove these parameters it show ALL records.
e.Command.Parameters("@Printed1").Value = Nothing 'ASP.NET 2.0 using Visual basice.Command.Parameters("@Printed2").Value = Truee.Command.Parameters("@Printed3").Value = False
What am I doing wrong???
Thanks

CancelSelectOnNullParameterHi,Suppose I have a SQLDataSource with a
SelectCommand="SELECT * FROM STOCKS WHERE USER=@USER ORDER BY STOCK_NAME"
and @USER is set as a session parameter. No problem till this part, but in some postbacks, I wish to add a new WHERE criteria to my SQL, so I do:DSSQL.SelectParameters.Add("@STOCK_NAME", "ABC123");
DSSQL.SelectCommand = DSgvStoklar.SelectCommand.Replace(" ORDER BY ", " AND STOCK_NAME LIKE @STOCK_NAME+'%' ORDER BY ");
gridViewDS.DataBind();
and wish that my SelectCommand is modified and a new parameter is added.
The SQL is modified, however -I guess- new parameter is not added, so I get "Must declare the scalar variable "@STOCK_NAME" error.
How can I solve, any ideas?
