Figure 11-11. Using the value method to retrieve job candidate last names Like the query() method described previously, the value() method sample XQuery query begins by declaring a namespace: declare namespace ns = "http://schemas.microsoft.com/sqlserver/2004/07/adventure-works/Resume"; The actual query portion of the XQuery query is a simple path expression: (/ns:Resume/ns:Name/ns:Name.Last)[1] Because value() returns a scalar value, the query is enclosed in parentheses with an XQuery numeric predicate [1] following it to force the return of a singleton atomic value. The second parameter passed into value() is the T-SQL data type that value() will cast the result to, in this case nvarchar. The value() method cannot cast its result to a SQL CLR user-defined type or an xml, image, text, ntext, or sql_variant data type.

DML triggers are composed of T-SQL code that is executed (fired) in response to an INSERT, an UPDATE, or a DELETE statement on a table or view. DML triggers are created via the CREATE TRIGGER statement, which allows you to specify the following details about the trigger: The name of the trigger, which is the identifier you can use to manage the trigger. You can specify a two-part name for a trigger (schema and trigger name), but the schema must be the same as the schema for the table on which the trigger executes. The table or view on which the trigger executes. The triggering events, which can be any combination of INSERT, UPDATE, and DELETE. The triggering events indicate the type of events that the trigger fires in response to. The AFTER/FOR or INSTEAD OF indicators, which determine whether the trigger is fired after the triggering statement completes or whether the trigger overrides the firing statement. Additional options like the ENCRYPTION and EXECUTE AS clauses, which allow you to obfuscate the trigger source code and specify the context that the trigger executes under, respectively.
