If the value does not satisfy the constraint of a target type, the following rules apply: Note The feedback system for this content will be changing soon.

Its value space includes the URIs defined by the RFCs 23, but its lexical space doesn't require the character escapes needed to include non-ASCII characters in URIs.Relative URIs are not "absolutized" by W3C XML Schema.function takes no parameters, and returns the current date and time, with time zone.If the function is called multiple times within the same query, it returns the same value every time. This description is © Copyright 2007, Priscilla Walmsley.For example, the following will succeed and generate a double value, 1.1e0: When casting to binary types such as xs:base64Binary or xs:hex Binary from a string or untyped Atomic type, the input values have to be base64 or hex encoded, respectively.
After a request from other W3C Working Groups, the W3C XML Schema Working Group decided to remove the obligation to include these line breaks from the constraints on the lexical space.This topic describes the type casting rules that are applied when casting from one type to another by using one of the following methods: The following example queries a typed xml variable.The example first creates an XML schema collection.Specifically, this can mean that a value that may have obeyed a specific pattern or other constraint during input will not be represented according to that constraint.To inform users about this, SQL Server flags types where the type constraint can be a problem by providing a warning when those types are loaded into the schema collection.
