I was wondering if anyone could advise on 'Xquery'
I have an xml column in my table its called and in that column i have data like as follows

<Referendum_You_Voted />
<Your_First_Choice>Micheal D Higgins</Your_First_Choice>
<Your_Second_Choice>Sarah McCarthy</Your_Second_Choice>
<Your_Third_Choice>David Norris</Your_Third_Choice>
<Your_Fourth_Choice>Mary Robinson</Your_Fourth_Choice>
<Your_Fifth_Choice>Barack Obama</Your_Fifth_Choice>

Table name results2
xml column name results_xml

I ultimately want to be able to count the results and display them to the user. i have this working using normal sql queries when i have the results stored in regular datatypes.

so essentially id like the results to read
most voted as 1st choice: micheal d higgins
most voted as second choice: sarah mccarthy etc etc.

Any help or examples would be appreciated. Ive looked online myself but ive not come across any examples that give a proper explanation of how the query's are assembled.

thanks in advance.

MSSQL 2005+ supports direct quering xml columns as well as indexing them.

Thus you should be able to run your typical queries with slightly modified criteria for XML fields:

CREATE TABLE results_xml  (pk INT PRIMARY KEY, FieldSQL XML not null)

insert into results_xml (pk,FieldSQL) values (1,'
<referendum_you_voted />
<your_first_choice>Micheal D Higgins</your_first_choice>
<your_second_choice>Sarah McCarthy</your_second_choice>
<your_third_choice>David Norris</your_third_choice>
<your_fourth_choice>Mary Robinson</your_fourth_choice>
<your_fifth_choice>Barack Obama</your_fifth_choice>

FieldSQL.value('(/ResultsDS/Results/Your_First_Choice)[1]', 'nvarchar(1000)')
,* from results_xml
FieldSQL.value('(/ResultsDS/Results/Your_Fifth_Choice)[1]', 'nvarchar(1000)')='Barack Obama'

Syntax is not exact, as I do not have SQL Server running now.

More information can be found on MSDN:[^]

Thanks for that it does produce a result which is better than the errors ive been getting. Im just looking to figure out now how to get the max count of a value (and the value) of an attribute in the XML data.
would you know off hand how to do that by any chance.

I suppose in a similar manner, but if necessary cast to another datatype, rather than nvarchar, if element contains number.

Make sure you put indexes on appropriate paths.
If your requirement is to shred XMl Data values you can do this as below:
Create table #tempTbl
Id int,
Insert into #tempTbl values (1,'<resultsds>
<your_first_choice>Micheal D Higgins
<your_second_choice>Sarah McCarthy
<your_third_choice>David Norris
<your_fourth_choice>Mary Robinson
<your_fifth_choice>Barack Obama

Insert into #tempTbl values (2,'<resultsds>
<your_first_choice>Barack Obama
<your_second_choice>David Norris
<your_third_choice>Sarah McCarthy
<your_fourth_choice>Mary Robinson
<your_fifth_choice>Micheal D Higgins

Insert into #tempTbl values (3,'<resultsds>
<your_first_choice>Barack Obama
<your_second_choice>Micheal D Higgins
<your_third_choice>David Norris
<your_fourth_choice>Mary Robinson
<your_fifth_choice>Sarah McCarthy


from #tempTbl tc Cross apply tc.Doc.nodes('ResultsDS/Results') e(x)

It will give you tabular data by which you can count occurence in each column to most voted for specific position
