We will use SWITCH() to enact conditional formatting in a couple of different ways. First, we will use it to drive formatting of a value to meet requirements that are based upon the magnitude of the value itself. As a part of our practice with SWITCH() to achieve our ends, we will delve into a popular formatting convention for negative (and other "outlier") numbers.

In this article, we are continuing coverage of Foreach Loop container functionality, by discussing different types of loop enumerators. So far, we have presented methods for working with files in a folder as well as records in a recordset (using Foreach File and Foreach ADO enumerators, respectively). Our next enumerator is based on the SQL Server Management Objects technology (hence it is referred to as the SMO enumerator), which is the SQL Server 2005, .NET-based management framework providing replacement for COM-based DMO (Distributed Management Objects) that served an equivalent role in earlier versions of SQL Server.

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, ';')

rows between unbounded preceding and unbounded following) as stragg
