Out of the box, Reporting services does not handle divide by zero conditions gracefully. There are plenty of posting on how to use the IIF() function to accomplish this, with some rather horrific looking code.

This is an example to overcome short comings when using BCP to create a 'proper' CSV file. The view vw_Customers_RAW is used in order to provide a method of creating the column heading row and to enclose columns with embedded comma with double quotes, which are not options in BCP. There are more generic methods […]

Comments posted to this topic are about the item 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; See possible answers
