Infertility now affects 1 in 25 men and one in five healthy young men between the ages of 18 and 25 produce abnormal sperm counts. The three prime causes of male infertility are reduced sperm motility, poor sperm viability and low testosterone levels. Scientific studies demonstrate that mobile phone radiation can cause all three.
WaveWall is an innovative, stylish mobile phone case that will not only protect your phone but will also reduce the harmful mobile radiation from your phone entering your testicles by more than 85%. Protection only on one side allows your phone to send and receive messages, calls and data as normal, even when inside WaveWall!

We're WaveWall, and this is our new phone case. Did you know that one in five people on the planet owns a smartphone?
That's a lot of calls, texts and tweets... and radiation. Scientists have shown that keeping your phone in your pocket can really damage your swimmers. That's pretty bad news if you want to have kids in the future. This is where our case comes in; our patent pending technology acts like a mirror, reflecting your phones radiation away from your equipment, so to speak.
Independent testing has shown our case to reduce radiation by up to 85%, but because protection is only on one side, your phone can still send and receive data as usual. So, if, like most guys, you're keen on keeping your tackle in top notch, you'd better do something fast. Get a WaveWall and protect your manhood!

A trigger is a named PL/SQL unit that is stored in the database and executed ( fired ) in response to a specified event that occurs in the database.
Overview of Triggers.
A trigger is a named program unit that is stored in the database and fired (executed) in response to a specified event. The specified event is associated with either a table, a view, a schema, or the database, and it is one of the following:
A database manipulation (DML) statement ( DELETE , INSERT , or UPDATE )
A database definition (DDL) statement ( CREATE , ALTER , or DROP )
A database operation ( SERVERERROR , LOGON , LOGOFF , STARTUP , or SHUTDOWN )
The trigger is said to be defined on the table, view, schema, or database.
A DML trigger is fired by a DML statement, a DDL trigger is fired by a DDL statement, a DELETE trigger is fired by a DELETE statement, and so on.
An INSTEAD OF trigger is a DML trigger that is defined on a view (not a table). The database fires the INSTEAD OF trigger instead of executing the triggering DML statement. For more information, see Modifying Complex Views (INSTEAD OF Triggers).
A system trigger is defined on a schema or the database. A trigger defined on a schema fires for each event associated with the owner of the schema (the current user). A trigger defined on a database fires for each event associated with all users.
A simple trigger can fire at exactly one of the following timing points :
Before the triggering statement executes.
After the triggering statement executes.
Before each row that the triggering statement affects.
After each row that the triggering statement affects.
A compound trigger can fire at more than one timing point. Compound triggers make it easier to program an approach where you want the actions you implement for the various timing points to share common data. For more information, see Compound Triggers.
