Disable a trigger.
Syntax
      DISABLE TRIGGER { [schema.] trigger [,...n ] | ALL }
         ON { object_name | DATABASE | ALL SERVER } [ ; ]
Key:
   object_name - The table or view on which the trigger was created to execute. 
   DATABASE    - The DDL trigger applies to the current database.
   ALL SERVER  - The DDL trigger applies to the current server.
Specifying DISABLE... ALL in a database that is published for merge replication will disable the merge triggers created by SQL Server, and will disrupt replication.
Example
DISABLE TRIGGER MySchema.MyTrigger1 ON MySchema.MyTable; DISABLE TRIGGER MyTrigger2 ON DATABASE;

  How you gonna come?
