Trigger For Creating New Table In SQL Server


Triggers are database operations that are automatically fired when an action such as Insert/Update/Delete is performed on a table or a View in a database.


Triggers are associated with the table or View directly; i.e., each table has its own triggers. The triggers are executed in place of any of Create operations.
Create trigger SQL Script
  1. Create TRIGGER [Tr_CreateNewTableByHost]  
  4. AS  
  5. BEGIN  
  6. declare @hostname varchar(30)    
  7. select @hostname = hostname FROM sys.sysprocesses WHERE spid = @@SPID    
  9.     Print 'New Table Created' + ' At ' + cast(Getdate() as nvarchar(20))+' Using Hostname '+@hostname  
  10. END  
  11. GO  
  12. ENABLE TRIGGER [Tr_SatyaCreateNewTable] ON DATABASE  
  13. GO   
Create trigger SQL description

Here, the name of the trigger for a Create Table operation is named Tr_CreateNewTableByHost on DATABASE. That means when any table is created, the trigger will be fired.

@hostname gets the value of system hostname / SQL Server hostname from the system pre-defined object name sys.sysprocesses.cast(Getdate() as nvarchar(20)) , this part will show you the date time the table created.

To enable a DDL trigger with database scope (ON DATABASE), a user must have ALTER ANY DATABASE DDL TRIGGER permission in the current database. 
  1. ENABLE TRIGGER [Tr_SatyaCreateNewTable] ON DATABASE
