Assigning Value To SessionParameters In SqlDataSource
May 22, 2008
Hello,
I am using SessionParameters within a sqldatasource control, which is the datasource for a formview control.
The Session["PoolID"] has a value which is '0000009485'.<InsertParameters><asp:SessionParameter SessionField="PoolID" Name="pool_id" Size="10" Type="String" ConvertEmptyStringToNull="true" />
</InsertParameters>But when I click 'Save' I get the message 'Cannot insert the value null into column 'pool_id'. Column does not allow nulls. Insert fails'.Do i need to specify something like DefaultValue = <%Session["PoolID"] %>?Thank you in advance for your help.RajanP.S. How can I avoid double line spacing while writing a post? Thanks.

The problem I'm having is described below all this code.---------------------------------------------------------My content page has a SqlDataSource: <asp:SqlDataSource ID="sqlGetUserInfo" runat="server"
ConnectionString="<%$ ConnectionStrings:RemoteNotes_DataConnectionString %>" SelectCommand="SELECT [UserFirstName], [UserLastName] FROM [Users] WHERE ([UserGUID] = @UserGUID)"
onselecting="sqlGetUserInfo_Selecting"> <SelectParameters> <asp:Parameter Name="UserGUID" Type="String" /> </SelectParameters> </asp:SqlDataSource> -----------------------------------------------------Inside my OnSelecting event, I have: protected void sqlGetUserInfo_Selecting(object sender, SqlDataSourceSelectingEventArgs e) { sqlGetUserInfo.SelectParameters["UserGUID"].DefaultValue = Membership.GetUser().ProviderUserKey.ToString(); } ---------------------------------------------------------------------And, inside my Page_Load, the relevant code is: //String strUserFirstName = ((DataView)sqlGetUserInfo.Select(DataSourceSelectArguments.Empty)).Table.Rows[0]["UserFirstName"].ToString();
DataView dvUserDetails = (DataView)sqlGetUserInfo.Select(DataSourceSelectArguments.Empty);
if ((dvUserDetails != null) && (dvUserDetails.Count > 0)) { DataRow drUserInfo = dvUserDetails.Table.Rows[0]; lblHelloMessage.Text = "Hello, " + drUserInfo["UserFirstName"].ToString() + ((drUserInfo["UserLastName"].ToString() == "") ? "" : " " + drUserInfo["UserLastName"].ToString()); } ---------------------Now, here's the problem. My "if" statement is never executing because "dvUserDetails" is null. However, when I break the execution and put awatch on the actual Select() statement, it shows a DataView with the correct return rows! You can see the commented line where I tried tobypass the DataView thing (just as a test), but I get an object reference is null error.The weird thing is that it was working fine one minute, then started getting "funky" (working, then not, then working, then not), and now it just doesn't work at all. All thiswithout me changing one bit of my code because I was checking out some UI flow and stopping and restarting the application. I've tracked downthe temporary files directory the localhost web server runs from, deleted all those files, and cleaned my solution. I've even triedrebooting, and nothing seems to make it work again.My relevant specs are VS2008 9.0.21022.8 RTM on Vista Enterprise x64.

Hi Guys,
I'm fairly new to .Net and have reached a point in the coding I can't seem to get past.
I've created a table with Visual Studio 2005 and MySQL Server 2008 (Beta) and am trying to make the "Select" button bind a result from that table (in this case, image_id) then open up that image ID in a Image details page, I've created the table in Visual Studio 2005.
Here's what I've got so far;
Page 1Protected Sub GridView1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)Dim row As GridViewRow = GridView1.SelectedRowSession("session_current") = row.Cells(1).TextServer.Transfer("page2.aspx")End SubI think this page isn't at fault as it reads the parameter into a text box on page2
Page2</asp:GridView><asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString3 %>"ProviderName="<%$ ConnectionStrings:ConnectionString3.ProviderName %>" SelectCommand="SELECT * FROM [profiles] WHERE ([profile_id] LIKE '%' + ? + '%')"><SelectParameters><asp:SessionParameter Name="profile_id" Type="String"/></SelectParameters>
I'd sincerly appreciate any help, any one may be able to offer,
Cheers,
Craig

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.

Consider the following:
Sub regUser(s as Object, e as EventArgs)
If IsValid Then
Dim stuTable as String
Dim connStr as String
stuTable = "mytable"
connStr = "myConnectionInfo"
'check to see that student num is in the db
Dim connect as SqlConnection
Dim strSelect as String
Dim cmdSelect as SqlCommand
Dim strDbResult as SqlDataReader
connect = New SqlConnection(connStr)
strSelect = "SELECT stu_num, stu_fname, stu_lname FROM " + stuTable + " WHERE stu_num=@stuNum"
cmdSelect = New SqlCommand(strSelect,connect)
cmdSelect.Parameters.Add("@stuNum", txtStdNum.text)
connect.Open()
strDbResult = cmdSelect.ExecuteReader()
Dim stuFName as String
Dim stuLName as String
Dim stuEmail as String
Dim strRandom as String
Dim strPassword as String
Dim i as Integer
Dim charIndex as String
Dim stuMailMessage as MailMessage
Dim strHTMLBody as String
'declare stuFname, stuLname, stuEmail
stuFName = strDbResult("stu_fname")
stuLName = strDbResult("stu_lname")
stuEmail = txtStdEmail.text
'more code follows ....
In my DB I have a table with the columns stu_num, stu_fname and stu_lname. Each of these columns contains rows with data. However, the proceeding code gives me this error: Invalid attempt to read when no data is present (line 58 --> stuFName = strDbResult("stu_fname") ).
What am I doing wrong here? How do I assign the stu_fname in the DB to the page level variable stuFName?
As a little aside how do I say "If no record was found matching stuNum Then" ... ??
Sorry, I'm a .NET beginner ...

Hi ,
I have a typical scenario here where I am trying to assign a variable a value using another variable, for that I am using two execute SQL task , the fisrt one assigns the first variable a value and then the second one uses the first variable to evaluate and then assigns a value to another variable. The first execute sql task works fine , however the second one fails with the following error
"failed with the following error: "An error occurred while extracting the result into a variable of type (DBTYPE_I4)". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly. "
Here is the query I am using to assign the value in my second execute sql task
select (CASE
WHEN Sum(col1) <> 0 AND ? = 'M' THEN 'M'
WHEN Sum(col2) <> 0 AND ? >= 'T' THEN 'T'
WHEN Sum(col3) <> 0 AND ? >= 'R' THEN 'R'
ELSE 'S'
END) as Current
FROM dbo.TABLE1
I am passing the variable by mapping the parameters and then assigning the value using a single row result set.
Can someone please tell me where am I going wrong?
Thanks

I’ve reconfigured Microsoft’s IBS Store shopping cart to function within a small e-commerce website. What I am trying to do is to modify the code slightly in order to use a third party credit card processing center. The situation is this: once the customer clicks the final "check out" button, a stored procedure writes all of the product ordering information into the database. I, then, capture what they're wanting to purchase with the following SQL statement:
Dim strSQL as String = "Select orderID, modelNumber from orderDetails" & _
"where CustomerID = " & User.Identity.Name & _
"And orderid = (SELECT MAX(orderid)FROM orderDetails" & _
"where CustomerID = " & User.Identity.Name & ")"
What I would like to do is assign specific values to variables based off of the above query. For example:
Dim orderItem as String = (all of the modelNumbers from the query)
Dim orderIdItem as String = (all of the orderIDs from the query)
How do I do this?? Any help is much appreciated! Thanks in advance.

Ok guys,
I'm realitvely new to the whole database development stuff, but I have a very important project to finish using SQL and ASP. I am to design a new links manager for a website.
Right now I have the following:
The ability to add a link, and edit it
The ability to add a category and edit it
When you go to add a link, a list of categories is provided for you, with checkboxes. What I need to do is figure out how to assign multipule categories to one link.
I have a Cross-Referencing table with three fields:
CrossRefID
LinkID
and CatID.
If you need more clarification, post here and let me know.
Thanks in Advance,

Hi I'm new to SQL and I'm trying to build a store procedure. What I'm trying to find out is how to assign a variable a value from a table.
So, I declare a variable:
DECLARE @variable int
Then I want to assign a single int value to that variable that is already in a table. For instance the id value from a single row in a table.
I've tried SELECT INTO and SET, but nothing has worked so far and I'm lost after searching for a few hours.
Thanks in advance for any help

I have the following problem:
in a data flow, if inserting new records, there are columns that take some default values. These default values are kept in a table in case the user wants to change them some day. Def. values could not be assigned at a table level because there's another dataflow that populates the same table, but the rules for the default values are different.
Since I want to extract these values only if there is at least one new row, I'm not fond of the idea to use Execute SQL Task (to save the default values in a variable) before the actual Data Flow. What are my options in getting these values in a Data Flow right before inserting? Thank you for the help.

Hi,
I would like to assign the value of a variable to a column name of a table. For eg:
declare @sam varchar(100)
set @sam = 'Insert'
create table #temp(Sample varchar(100) not null)
insert into #temp(Sample) Values(@sam)
drop table #temp
I would like to generate a table whose column name should be generated dynamically. The value of @sam that is "Insert "should be set to the column name. Is there a way to assign like this. Can anyone please help me in achieving this.

Hi,
1 20031012121212 200 (recordtype, CreationDateTime(YYYYMMDDHHMISS), Rec_Count) -- Header records
2 ABCD, XYZ, 9999, 999999999, 1234 ---- Detailed Record
2 ABCD, XYZ, 9999, 999999999, 1234 ---- Detailed Record
For the above given sample data I am having two outputs at Condition Split (based on the recordtype). I want to store the 1st record datetime value into a variable and then I want to use that variable value into 2nd and 3rd row.
Basically, detailed records would be stored into the database not the header record. Is there any way I can use the variable while doing processing for 2nd and 3rd records.
Please suggest me.

Hi,
I have a parent SSIS package that executes various subpackages. Each of the subpackages contain variables that are required for their successful execution, e.g. one has a variable of datetime datatype and a variable of varchar datatype.
This date will essentially change with every running of the package as it specifies the date that additional data has been added to the back-end SQL Server 2005 database.
I can't find anything in the expressions of the Execute Package Task that would allow me to pass these variables into the package.
Can anyone advise?
Thanks,
Paul

I'm trying to assign a datasource to a gmap control in 2.0 so that i can get pushpins in the map for all the locations in the sql db. I've enclosed my code below as well as a link to the site that provides the control and their sample. Can anyone tell me why it won't show the pins? What am I doing wrong?
Thanks.
My Code (sqllocations is a datasource):
GMap1.DataSource = sqllocations;
GMap1.DataBind();
Their site: http://en.googlemaps.subgurim.net/ejemplos/ejemplo_991000_DataSource.aspx
Their example (part of their explanation is not english, sorry):
List<DataSourceField> fields = new List<DataSourceField>(); fields.Add(new DataSourceField(45, 2, "hola"));fields.Add(new DataSourceField(46, 3));// Lo comentamos porque al utilizar la clase DataSourceField, // pero si fuera un dataset o cualquier otra cosa, // le deberíamos dar los nombres correspondientes// GMap1.DataLatField = "lat";// GMap1.DataLngField = "lng";// GMap1.DataGInfoWindowTextField = "gInfoWindowText";GMap1.DataSource = fields;GMap1.DataBind();

Hi ,
I will need some examples in assigning and getting values using SQLServer 2005. For eg. How can I store the value that I retrieved in a variable and return that value ? How can I use a function inside a stored procedure ? Do we have any examples or some simple sample code just to take a look ?
For eg I have written the following function which I called from a stored procedure.
BEGIN
--Declare the return variable here
DECLARE @Rows NUMERIC(10)
DECLARE @RETURN_ENABLED VARCHAR(1)
-- Add the T-SQL statements to compute the return value here
SELECT @Rows = MAX(PROFILE_INDEX) FROM PROFILE_PERMISSION PP
INNER JOIN sys_menu_item ON PP.MENU_ITEM=sys_menu_item.menu_item
WHERE PP.PROFILE_INDEX in (select up.profile_index from user_profile up where up.user_id= @is_user) and
not exists (select up.profile_index from user_profile up where up.user_id= @is_user and up.profile_index=1) and
PP.APPLICATION_CODE = @is_appl AND
PP.MENU_NAME=@menu_name
Group By Profile_INdex
IF @Rows > 0
SELECT @RETURN_ENABLED = 'N'
ELSE
SELECT @RETURN_ENABLED = 'Y';
-- Return the result of the function
RETURN @RETURN_ENABLED;
END
Is it correct ? The variable @ROWS will be assigned with the values that the sql statement will return ?
From the stored procedure I'm calling the function inside a CTE.
;WITH GetHierarchy (item_text ,orden , read_order, item_parent , menu_item , enabled)
AS
(--Anchor.
select tb1.item_text, tb1.orden, tb1.read_order, tb1.item_parent , tb1.menu_item ,
dbo.f_sty_print_menu_per_role_per_app2(@menu_name , @is_user , @is_appl) as enabled
From sys_menu_item as tb1
where tb1.MENU_ITEM not in ('m_window','m_help','m_toolbar') and tb1.item_parent not in ('m_toolbar','m_window','m_help')
And tb1.item_parent= @menu_name
--Members
UNION ALL
select tb2.item_text, tb2.orden, tb2.read_order, tb2.item_parent , tb2.menu_item ,
dbo.f_sty_print_menu_per_role_per_app2(@menu_name , @is_user , @is_appl) as enabled
from sys_menu_item as tb2 , GetHierarchy
where tb2.MENU_ITEM not in ('m_window','m_help','m_toolbar') and tb2.item_parent not in ('m_toolbar','m_window','m_help')
And tb2.item_parent = GetHierarchy.menu_item and tb2.menu_name = @menu_name
)
select Space(5*(orden)) + item_text as menui, orden, read_order, item_parent , menu_item ,enabled
From GetHierarchy
Am I doing it correctly ?
I would appreciated any help you could give me.
Thank you
