Xquery declare updating function

Let's populate the Accounting node with a new Employee node, which should include node attributes (ID, tier): Going back for a moment to the subject of singletons; if we had used '[2]' as the singleton designation, the new Employee node would have been placed in the bottom Accounting node.What if we needed to insert a new node into a specific Employee node in the Marketing department?You may notice that we designated a singleton (single node value) representation of [1]' for Expression 2 (the Salaries destination node).

We can identify the correct employee by their ID attribute, using the @ID' argument: The Projects node has been inserted into the Employee node having ID #2.

We can also insert any collection of nested nodes and values.

XQuery is simpler to work with and easier to maintain than many other alternatives.

Do more with less.” XQuery does not define updating.

[..] A function declaration specifies whether a function is user-defined or external.

For a user-defined function, the function declaration includes an expression called the function body that defines how the result of the function is computed from its parameters.” See the XQuery article.

It's the equivalent of the example discusses in the PHP - My SQL - XML tutorial - basics tutorial.

Instead of using XSLT to format a typical database result table, we use XQuery.

Standards: Let's recall that XQuery uses XPath elements.
