Thank you both for your answers.
I am looking at an OLD SQL CRM application that
lets you create Views (application related Views and
not SQL Views) of your Companies list. You
select company names from all the Companies list
and then save the Views for later re-use.
For example the app displays me 50,000 companies
and I manually select 10 of them and save my
first view and give it a name "My Top 10 clients".
Another example I would select "My Top 100 clients"
and another "My Top 1000 clients".
If I do this right now in this app those 1000 ClientNos
will be stored in one IMAGE column on the same
record where my View information "My Top 1000 clients"
is being saved.
If I run the SQL Profiler every time I save my
View I see a lot of calls for "sp_cursorfetch" (I think)
or when I call my View to load I see a lot of cursor calls
(I am not sure if I remember if they were actually cursor
calls) but I saw a #Temptable being created and each
selected ClientNo's Name being inserted to this temp table.
Well it didn't look nice the SQL Profiler statements so
that's why I was just trying to see if the developer(s) of
this old CRM I was looking at had good reason(s)
to store the selections of a user into a single column.
Based on your answers if I need to implement such
a scenario I will stick to One-to-Many table relationship
for all the reasons you have explained.
Thanks again
