XQuery constructors

XQuery constructors create XML structures within a query. .

Enclosed expressions in constructors
Enclosed expressions are used in constructors to provide computed values for element and attribute content. These expressions are evaluated and replaced by their value when the constructor is processed. Enclosed expressions are enclosed in curly braces ({}) to distinguish them from literal text.
Direct element constructors
Direct element constructors use an XML-like notation to create element nodes. The constructed node can be a simple element or a complex element that contains attributes, text content, and nested elements.
Document node constructors
All document node constructors are computed constructors. A document node constructor creates a document node for which the content of the node is computed based on an enclosed expression.
Processing instruction constructors
Processing instruction constructors create processing instruction nodes. Db2 for z/OS® supports direct constructors for creating processing instruction nodes.
Comment constructors
Comment constructors create comment nodes. Db2 for z/OS supports direct constructors for creating comment nodes.
