CREATE OR ALTER - another great language enhancement in SQL Server 2016 SP1

  • Статья

We are happy to announce that SQL Server 2016 SP1 and SQL Server v.Next have new T-SQL language statement - CREATE [OR ALTER]. This statement combines CREATE and ALTER statements and creates object if it does not exist, or alter it if it is already there. CREATE OR ALTER can be applied on the following object:

This is one of the most voted language feature requests on SQL Server connect site with more than 500 votes. A code that uses CREATE OR ALTER is shown in the following example:

 create or alter procedure procTest
as
begin
 print (1)
end;
go
create or alter function fnTest()
returns int
as
begin
 return(1)
end;
go
create or alter view vwTest
as
 select 1 as col;
go
create or alter trigger trTest 
on Product 
after insert, update 
as
 RAISERROR ('We love CREATE OR ALTER!', 1, 10);

We hope that this statement would help you to to write easier T-SQL code.

EDIT (11/17/2016): This and other SQL Server 2016 SP1 topics are also available in the SQL Server Tiger blog.

    Oh man, I've been asking for this for about 15yrs. and it's finally here. This is WONDERFUL. Now backport it to a couple other versions and we'll be golden.

    does alter preserve permissions?

      Hello George, it does not change existing permissions for existing objects.

    I hope it won't take another 15 years to see an easy to use INSERT OR UPDATE statement! The MERGE synthax is orrible.

    It does not seem to accept the CREATE or ALTER format in the SSDT database projects and shows error when I checkin the procedure with the new format.Can you confirm if it has been part of SSDT as well?

    I hope the "Modify" and "Script... to" menu options will automatically add " or alter" to existing objects.

    We need this in SQL Server 2005, 2008, 2012 and 2014 too.

      Duh!SQL Server 2005 is no longer supported.And SQL Server is out of Standard support.Perhaps you should focus on upgrading SQL Server to the later editions instead of getting Microsoft to backport it...No?

    Should we be getting red underlines from IntelliSense when using create or alter on an object that exists? We're using SQL 2016 SP1 and SSMS 2016 version 13.0.16106.4.

    It's a great feature... but who's idea was it to add it in a service pack???Now we have no idea if we can run it in based on compatibility mode or not...130 with SP1 can run it, and 130 without SP1 can't... what a mess...
