Overcoming OpenXML Hangups

If you're writing an application that uses XML as a data-interchange format, you need a way to extract the data from the XML document and store that data in your database. T-SQL's OpenXML keyword is a convenient way to insert, delete, and update data in SQL Server 2000. OpenXML creates one or more relational views (or rowsets) of the XML document within a T-SQL stored procedure. You can access the data in those views to perform relational operations on your database. Although OpenXML is fairly easy to work with, you need to overcome a few hurdles before you can use it in real-world applications. I've discussed the largest stumbling block—the difficulty in passing an XML document to a stored procedure—in my Exploring XML columns in July 2001, InstantDoc ID 21077, and August 2001, InstantDoc ID 21259. Now let's look at two other common OpenXML obstacles you might encounter.
