Hi Stig,
in order to manipulate a database with Stylus Studio you need to create an XQuery document, set the processor to be DataDirect XQuery, and then use the ddtek:sql-delete function.

Hope this helps,
Alberto

Hi Stig,
you invoke the ddtek:sql-delete function on the XML node you fetched from the database table; for instance, if you want to delete all the rows from the "holdings" table having the "userid" column equal to "Stig" you write:

ddtek:sql-delete(collection("holdings")/holdings[userid = "Stig"])

Hope this helps,
Alberto

Hi Alberto!

Thank's for your quick response!

We still have problems, for example with
the declaration of the external function (ddtek:sql-delete) !

Following is the XQuery code :

declare function ddtek:sql-delete($row as element()*) external;

ddtek:sql-delete(collection("pubs.dbo.StylusTest")/StylusTest[FNAMN = "Stig"])

We receive the following error :

[DataDirect][XQuery]Error at line 2, column 18. The namespace uri of external function declarations must start with "ddtekjava:".

Do you have a complete example for an XQuery ?

We are running Stylus Studio 2006 Enterprise Edition.

Ah. Delete wasn't available at that point.
You need Stylus Studio 2007 Release 2.
