Question

I have a MySQL database from which a view is created. Is is possible to add an auto-incrementing id for each row in the view?

I tried

CREATE ALGORITHM=UNDEFINED DEFINER=`database_name`@`%` SQL SECURITY DEFINER VIEW `MyView` AS 
set @i = 0;
select  @i:=@i+1 as `id`
        ...

but that doesn’t work in a View.

Sorry – you can’t autoincrement in a VIEW (You could do this in a Stored Procedure though).

From the MySQL Manual:

A view definition is subject to the
following restrictions: The SELECT
statement cannot refer to system or
user variables.
