Restrict SP_ (Naming convention) with DDL Trigger

Sometimes naming convention also impact the performance problem in SQL SERVER. Whenever we creating the stored procedures we are giving the name just like SP_Get_Customer. SP_ it first checks the Master Database system procedures. All the system procedures stored in Master Database.
In this article we do not allow SP_ whenever stored procedure creating by using DDL Trigger.

--Create Student Table
create table Student
(             
                id int identity(1,1) ,
                Name varchar(100)
)

--Create DDL Trigger on Database
create  trigger Restrict_Sp_NameConvenction
on database
for create_Procedure
as
begin
declare @EventData XML = EVENTDATA(),@ObjectName Nvarchar(100);
select    @ObjectName=@EventData.value('(/EVENT_INSTANCE/ObjectName[1]','NVARCHAR(100)');
                if(substring(@ObjectName,1,3)='sp_')
                begin
                                raiserror('Procedure name can not be start with sp_',16,1)
                                rollback;
                end
end

--Create Stored Procedure Name starts with sp_
create procedure sp_Get_Student
 as
 begin
                select * from Student
 end

Msg 50000, Level 16, State 1, Procedure Restrict_Sp_NameConvenction, Line 10
Procedure name can not be start with sp_
Msg 3609, Level 16, State 2, Procedure sp_Get_Student, Line 1
The transaction ended in the trigger. The batch has been aborted.

--Create Stored Procedure Name does not starts with sp_
create procedure usp_Get_Student
 as
 begin
                select * from Student
 end

--Command(s) completed successfully.
  
 drop procedure sp_Get_Student

-- Disable trigger from Databse
disable trigger Restrict_Sp_NameConvenction on database

--Enable trigger from Databse
Enable trigger Restrict_Sp_NameConvenction on database

--Drop trigger from Databse
drop trigger Restrict_Sp_NameConvenction on database

--For more information about trigger event types
 select * from sys.trigger_event_types
