Using an implementation of XSLT formatting objects, you can transform your dynamic XML data into a binary format like PDF on the fly. To prove the point and see how it is done, we extend our watch list example to generate PDF files rather than HTML documents in this section. For an implementation of XSL formatting objects, we turn once again to the Apache Software Foundation. ASF has a project called FOP that is currently a partial implementation of formatting objects. You can download the binaries, source, and documentation from http:/ /xml.apache.org/fop. For the sake of discussion, let us suppose that we need to output the stock watch list page in PDF format instead of HTML for web-based clients. Perhaps we have a fraud concern that someone might download the HTML source, modify it, and then claim that our pricing information was incorrect and cost

There s no built-in way to suppress a trigger for a particular statement . You can only disable a trigger completely using an ALTER TABLE DISABLE TRIGGER command . If you want to prevent a trigger from firing for a particular statement, you have to develop your own programmatic solution . You need to somehow signal the trigger that you don t want it to run its code . One way to achieve this is by creating a temporary table with a particular name (for example, a GUID) in the calling batch . Remember that a local temporary table is visible only to the creating session, in the calling level, and all levels inner to it . The trigger can first check

whether a temporary table with that particular name exists and, if it does, return . Otherwise, the code can continue running normally . Back in the calling batch, you can drop the temporary table when you don t want to prevent the trigger from running its code anymore . To demonstrate this solution, first run the following code, which creates the table T1:

USE tempdb; IF OBJECT_ID('dbo.T1', 'U') IS NOT NULL DROP TABLE dbo.T1; CREATE TABLE dbo.T1(col1 INT);

Next, run the following code to create the trigger trg_T1_i:

(including dependent objects)

CREATE TRIGGER trg_T1_i ON dbo.T1 FOR INSERT AS IF OBJECT_ID('tempdb..#do_not_fire_trg_T1_i') IS NOT NULL RETURN; PRINT 'trg_T1_i in action...'; GO

The trigger uses the OBJECT_ID function to determine whether a temporary table called #do_not_fire_trg_T1_i exists . If the table does exist, it returns . If the table doesn t exist, the code continues running normally . Note Remember that temporary tables are created in tempdb . Make sure that when

using the OBJECT_ID function to determine whether a temporary table exists, you database-qualify the object name . If you are connected to another database and invoke the function without the tempdb prefix, you ll always get a NULL back .

INSERT INTO dbo.T1 VALUES(1);
