Database Change Management: An Automated Approach

SQL Server change management is tough. The tools don't integrate with version control systems, there isn't good administrative controls to enforce control, and often you need to buy a third party tool to make this work. New Author Darren Fuller takes a look at the various ways in which you can implement version control in SQL Server. This is part one of a four part series on version control in SQL Server.

Question of the Day

The string_agg function

We create the following table and then insert some records in it:

create table t1 (
   id int primary key,
   category char(1) not null,
   product varchar(50)
);

insert into t1 values
(1, 'A', 'Product 1'),
(2, 'A', 'Product 2'),
(3, 'A', 'Product 3'),
(4, 'B', 'Product 4'),
(5, 'B', 'Product 5');
What happens if we execute the following query in both Sql Server and PostgreSQL?
select id, 
category, 
string_agg(product, ';')
                 over (partition by category order by id
                 rows between unbounded preceding and unbounded following) as stragg
from t1;
