SQL Trigger Syntax

I have a table e.g. SalesMaster with a field 'Status'. I want to detect if the status changes to '\' or '*' and then send an email (I know how to do this bit)
Can anyone help with the syntax, and will the asterix cause a problem?

You can write something like this.

CREATE TRIGGER notify_mail
ON SalesMaster
  DECLARE @stschk CHAR(1)
  SELECT @stschk = Status from updated
  IF  @stschk in ('\' , '*')
        EXEC msdb.dbo.sp_send_dbmail
          @recipients = 'email@yourcompany.com', 
          @profile_name = 'default',
          @subject = 'Status Changed', 
          @body = 'Status Changed.';

I would do something like this:

if exists (select * from sysobjects where name = 'myTrigger' and type = 'tr')
    drop trigger myTrigger

create trigger myTrigger
on SalesMaster
for update
    declare @nvchOldStatus nvarchar(1),
            @nvchNewStatus nvarchar(1)

    select @nvchOldStatus = Status from deleted
    select @nvchNewStatus = Status from inserted
    -- If there has been a change in the status field
    if @nvchNewStatus <> @nvchOldStatus
        if @nvchNewStatus in ('\', '*')
            -- send your email
