The simple answer is ingested gluten. But iodine (potassium iodide, iodized salt, kelp), some anti-inflammatories and stress can exacerbate the disease. An area of controversy is whether or not gluten can be absorbed through the skin. Most medical experts say no, only dietary gluten is of concern. DH can be "exquistely sensitive" to gluten. Since the skin may not be rid of the IgA deposits for 2+ years after starting a gluten-free diet, flare-ups may continue to occur.

Where are triggers stored?

Appendix A. Frequently Asked Questions About MySQL 5.1
Triggers are currently stored in .TRG files, with one such file one per table. In other words, a trigger belongs to a table. In the future, we plan to change this so that trigger information will be included in the .FRM file that defines the structure of the table. We also plan to make triggers database-level objects - rather than table-level objects as they are now - to bring them into compliance with the SQL standard.

How are triggers managed in MySQL?

Appendix A. Frequently Asked Questions About MySQL 5.1
In MySQL 5.1, triggers can be created using the CREATE TRIGGER statement, and dropped using DROP TRIGGER. See Section 19.1, "CREATE TRIGGER Syntax", and Section 19.2, "DROP TRIGGER Syntax", for more about these statements. Information about triggers can be obtained by querying the INFORMATION_SCHEMA.TRIGGERS table. See Section 22.16, "The INFORMATION_SCHEMA TRIGGERS Table".

Can triggers access tables?

Appendix A. Frequently Asked Questions About MySQL 5.1
A trigger can access both old and new data in its own table. Through a stored procedure, or a multi-table update or delete statement, a trigger can also affect other tables.

Do triggers work with replication?

Appendix A. Frequently Asked Questions About MySQL 5.1
Triggers and replication in MySQL 5.1 work in the same wasy as in most other database engines: Actions carried out through triggers on a master are not replicated to a slave server. Instead, triggers that exist on tables that reside on a MySQL master server need to be created on the corresponding tables on any MySQL slave servers so that the triggers activate on the slaves as well as the master.

What is a default order?

What triggers RRP initially?

FAQ
ldquo;To all of you who wonder what triggered your RRP to start with, doctors and scientists who work with this disease cannot say for any individual patient. However, there are several things we do know: Many people carry HPV in their throat without any disease. We call this virus latency. At least 5% of the people have latent virus, while 10 people in a million have RRP. Big difference! Obviously, most of the time the virus causes no problem.

Is there a way to view all triggers in a given database?

Appendix A. Frequently Asked Questions About MySQL 5.1
Yes. You can obtain a listing of all triggers defined on database dbname using a query on the INFORMATION_SCHEMA.TRIGGERS table such as the one shown here: SELECT TRIGGER_NAME, EVENT_MANIPULATION, EVENT_OBJECT_TABLE, ACTION_STATEMENT FROM INFORMATION_SCHEMA.TRIGGERS WHERE TRIGGER_SCHEMA='dbname'; You can also use the SHOW TRIGGERS statement, which is specific to MySQL. See Section 13.5.4.29, "SHOW TRIGGERS Syntax".

How are actions carried out through triggers on a master replicated to a slave?

Appendix A. Frequently Asked Questions About MySQL 5.1
First, the triggers that exist on a master must be re-created on the slave server. Once this is done, the replication flow works as any other standard DML statement that participates in replication. For example, consider a table EMP that has an AFTER insert trigger, which exists on a master MySQL server. The same EMP table and AFTER insert trigger exist on the slave server as well.
