I am having difficulty trying to return data in a very compact form. Here is
a simple example that will explain the problem:
I have a table with column E, T and P containing data such as
A, 1, R
A, 1, S
A, 2, R
A, 2, S
Trying the query
select E, group_concat(T,';'), group_concat(P,';') give me

Ahhh
the DISTINCT keyword was what I'm missing. However, this may be a bug,
when I use group_concat(DISTINCT T, ';') I get the error message
