Count Value In XML Field Via XQuery

Posted By:      Posted Date: September 13, 2010    Points: 0   Category :Sql Server
I have an XML field in SQL Server 2008. Within the XML is a node entitiled "Key".  There are some XML fields that will have the same value of 'Key'.  I want to count how many duplicates per 'Key'.  For example, if I query :  select   messagebody.query('/msg/body/Color/Key') from #t then the result might be: <Key>735110040</Key> <Key>0115220</Key> <Key>735110040</Key> I need to get the following output: 735110040, 2 0115220, 1 If I incorporate the traditional a count/group by with XML then I can't use group by as normal or I get "Cannot use an aggregate or a subquery in an expression used for the group by list of a GROUP BY clause." : select   messagebody.query('/msg/body/RetrieveAccount/Key'), count(('/msg/body/RetrieveAccount/Key'))from #t  group by count(('/msg/body/RetrieveAccount/Key'))  I've tried variations on the xquery count() function but I keep getting something wrong.  Does anyone know what the correct syntax for this scenario would be? Thanks, cj

Individual field - MySQL



I was wondering how to recieve an individual field from my MySQL database.

I have been able to get a row, but what I am trying to do is get a name from my database and set it into the HeaderText in my DataGrid.

The way I am trying to do it at the moment is

using (OdbcCommand cmd = new OdbcCommand(formQuery, con))
                formDataGrid.Columns[0].HeaderText = cmd.ExecuteReader(
                    CommandBehavior.CloseConnection |

This doesn't seem to get a value from the GetValue, but if use

using (OdbcCommand cmd = new OdbcCommand(formQuery, con))
                formDataGrid.DataSource = cmd.ExecuteReader(
                    CommandBehavior.CloseConnection |

it will bind my data into the grid.

I just want to be able to change the HeaderText in the first coulmn of the DataGrid from one table and have the DataGrid be filled from another table.

I can fill the DataGrid its just changing the HeaderText that I am having trouble with.

Any help?

Count words in the ascx file



I have 163 .resx files. I want to count the words in these files, because my want to translate the sentences (my task is the localisation).

Now I'm opening each file in Ms Visual Studio and I count words manually. How can I count words in all files? And the second question: can I use a program what grab strings from .resx into an editor where I can translate them and save bacn into .resx files? Or must open the files one by one and edit the text fields manually?

Thanks for helping, unfortunately I'm not a programmer.

How to display a count of search results with keywords in a label?


Sorry for a basic post here; I am very new to VB!

I am currently building a search page, which includes a textbox and two drop-down lists, a search button, and a datagrid. If results are found and displayed, I would like a label to display:

(e.g.) "24 results found for 'blue sky clouds' "

...where the integer represents the results count, and the keywords and/or drop-down list selections are included in the string.

If no results are found I would like the label to display:

(e.g.) "No results were found that match your selection. Please try again"

I would also like the label to be invisible until a search occurs.

Thanks in advance!

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.
