How to use variable in XQuery

Posted By:      Posted Date: September 24, 2010    Points: 0   Category :ASP.Net

I want to use a local sql variable in XQuery.

Following is my table structure with columns and data type.










OrderDetail column contains XML in the following form.

  <Book BookID="033ba62a-3bbe-48cc-ad15-c3f28ff86306" Title="XYZ" Price="120" />
  <Book BookID="805BC2BE-A91E-4E0E-A99E-C290D2EEEFF6" Title="XYZ" Price="120" />

I want to select Orders (rows) which have BookID = "033ba62a-3bbe-48cc-ad15-c3f28ff86306". I am able to achive it through the following query.

Select * From Orders Where OrderDetail.exist('//Book[@BookID = "033ba62a-3bbe-48cc-ad15-c3f28ff86306"]') = 1

Now the issue is I want to use an sql local variable (@BookID) instead of the hardcoded BookID.

So How I can use a sql variable in a XQuery.

Local variable scoping in C#

In my previous post, Compiler-generated scopes for local variable declarations, I briefly touched on the issue of multiple meanings applied to the same name. In this post, I'll aim to flush out the compiler's rules with regards to binding names in their local scopes.

Compiler-generated scopes for local variable declarations

I was tasked with understanding and fixing a bug on error reporting with foreach iteration variables the other day, and it got me thinking about local variable scoping rules in C# in general. First, the bug.

Retrieving a variable from a previous page



I'm looking to have a search page where a user will select an item from a listview, then then taken to another page that wil display data based on their original selection.

A user will type in a string and be presented with a list of usernames that are like that string, when they select a user name who's profile they would like to view I would like the page that they're taken to, to be that users profile.

How would I transfer the variable from the search page to the profile page, and when I work on the profile page, how can I access that variable?


Embeb a variable number of videos


I need to provide some alternate content for my non-Flash users.

I have a directory of video files that is scanned using the DirectoryInfo() function, and I want to use the results to embed all files ending in ".mov" in QuickTime players on a web form.

How would you approach this? Right now I am using the count on the array of videos to determine how many times to repeat the embed code.  But this seems inelegant.

Is there a way to have a single QuickTime player.ascx control that gets duplicated according to the number of videos available for display?

How to take value of bound field of grid in a variable or in a textbox.


How to take value of bound field of grid in a variable or in a textbox.

Hidden variable has no value


I know I have a valid solution, but the js is telling me that the value in the hdnRecordSaved variable has no value!
Even when I specify in my function the following, it still tells me it has no value:
var myTextField = document.getElementById('hdnRecordSaved');

When I put the full value of the variable in (ctl00_ctl00_cphTopCenter_cphCenter_hdnRecordSaved.value), I get the correct contents back ("1"), which I set in my code behind. However, I would prefer to just put the short name in since the masterpages may change, etc. Unfortunately, I know I can get around this with VS2010, but we are using VS2008.

What am I doing wrong with the js naming conventions that can't give me the contents? Here is my below js.

<asp:Panel ID="pnlMapFields" runat="server" ScrollBars="Both" Height="430px">

<telerik:RadTreeView ID="RadTreeView1" runat="server" DataTextField="Description"

DataFieldParentID="MapFieldparentID" DataF

How to retrieve data from SqlDataSource and pass to a variable?


Hi there,

I have a page in my website where there is very little code-behind. I only have two lines of code in Page_Load() and the rest of the code is declarative ASP.NET code. I have a FormView control which uses a SqlDataSource to get some order information. The SqlDataSource calls a stored procedure called usp_GetOrderDetails, here's the code for the SqlDataSource:

    <asp:SqlDataSource ID="sdsFormOrderDetails" runat="server" 
ConnectionString="<%$ ConnectionStrings:ForexDB %>"
ProviderName="<%$ ConnectionStrings:ForexDB.ProviderName %>"
SelectCommand="usp_GetOrderDetails" SelectCommandType="StoredProcedure"
UpdateCommand="usp_UpdateOrder" UpdateCommandType="StoredProcedure"
<asp:ControlParameter Name="orderId" ControlID="grdOrders" PropertyName="SelectedDataKey.Value" />
<asp:ControlParameter Name="orderId" ControlID="frmOrderDetails" PropertyName="SelectedValue" />

Data Points: Using XQuery, New Large DataTypes, and More


SQL Server 2005 introduces a lot of new features, but it also enhances the popular and oft-used Transact-SQL (T-SQL) language. Changes include the introduction of new datatypes to store large values using the MAX indicator, the integration of enhanced XML querying and data modification with XQuery, and the new XML datatype.

Session Variable issues


Hello everyone,

I ran into an issud to day with the follwoing code.  The strPanelOrder session variable is false, however, once it goes into the next if statement and sets the strTrimOrder to True, it changes the strPanelOrder session varialbe to true as well.  Why is this and how to I stop that from happening?

If Session(strPanelOrder) Is "False" Then
                If (strItemNumber.Length() = 10) And (strItemNumber.Substring(0, 2) = "FS" Or strItemNumber.Substring(0, 2) = "FC" Or strItemNumber.Substring(0, 2) = "DS" Or strItemNumber.Substring(0, 2) = "DC") Then
                    Session(strPanelOrder) = "True"
                End If
End If
If Session(strTrimOrder) Is "False" Then
               If (strItemNumber.Substring(4, 1) = "T") And (strItemNumber.Substring(0, 2) <> "AC") And (strItemNumber <> "Length") Then
                    Session(strTrimOrder) = "True"
                End If
End If


Thanks in advance for taking a look at this.

Textbox text populated by Session Variable wont update into SQL with new text


Hi everyone, I have what I think is a weird issue. I send text from one page to another via Session Variable. When page 2 loads, the text box has the session text set, but if the user changes the text and clicks the button, the SQL database is update with the original session text. If I remove the redirect from the page 2 button_Click method, then, the page refreshes with the textbox reverting to the session text and thr SQLDataSource has the session text added to it.

Why would the button click cause the textbox refresh with the text from the pageLoad before updating the data source?

Pass the server variable to search core result web part


I'd like to custom the search core result web part to filter results based on the log on user name.

It can easily be done in Dataview web part.

However the search core web part doesn't accept "<parameterbining>" to pass in the server variable [logon_user]. I can't figure out how to use <xsl:param> to get this server variable either.


Any ideas? Thanks a lot!

Submtting Calendar items with variable date information via InfoPath 2007 form



I've seen several posts regarding submitting to a list using and InfoPath form which I am successfully able to do in limited form. (only passing a basic date value) My environment: MOSS 2007 Enterprise w/SP2, InfoPath 2007, SPD 2007.

I'm basically trying to recreate a calendar form with the same data elements (and some additional ones for a specific business requirement) as the standard calendar newform.aspx form. (start time, end time broken down by date, hour, minute and All day event)

I need the form users to be able to select the date and if it is not an All day event...be able to select the hours and minutes just like on the newform.aspx. (date picker control for date and drop downs for hour and minute selection)

On submit I then need to create the list item with the appropriate data passed via a workflow.

My Start Time has a validation rule to not allow dates prior to the current date (and it can't blank) The End Time has a validation rule to not allow dates prior to what is specified as the Start Time value. (Also can't be blank) When I attempt to include conditonal formatting to hide the hour and minute drop downs if 'All Day Event' is selected I get errors stating the fields can't be blank.

I also can't figure out how to pass the entire date/time values or the All Day Event to the list withou

Function and Variable declaration with out an 'As' clause
