Dynamic TSQL Query output as XML - sql

Question

I have a dynamic TSQL query that is working perfectly. However, before I had it dynamic like this I was returning it as an XML output.
How can I do the same with my output now? I need the results in an XML format.

You need to take your existing Dynamic SQL, added the FOR XML... to the end, wrap that in parenthesis, and set that value to a variable which is used as OUTPUT for the sp_executesql. For example:
DECLARE #SQL NVARCHAR(MAX),
#Results XML;
SET #SQL = N'
SET #Out = (SELECT * FROM sys.objects FOR XML AUTO);
';
EXEC sp_executesql #SQL, N'#Out XML OUTPUT', #Out = #Results OUTPUT;
SELECT #Results;
So declare a new variable at the top for:
DECLARE #Results XML;
Then just before your EXECUTE sp_executesql #sSQL... line, do the following:
SET #sSQL = N'SET #Results = (' + #sSQL + N' FOR XML {xml options});';
Then update your param spec for sp_executesql to include, at the end:
N'#_category INT, ..., #Results XML OUTPUT'
And add the following to the end of the sp_executesql:
#_category = #category, ..., #Out = #Results OUTPUT
