Hi,

I'm working on a system migration and I need to combine data from multiple
rows (with the same ID) into one comma separated string. This is how the
data is at the moment:

Company_ID Material
0x00C00000000053B86 Lead
0x00C00000000053B86 Sulphur
0x00C00000000053B86 Concrete

I need it in the following format:
Company_ID Material
0x00C00000000053B86 Lead, Sulphur, Concrete

There is no definite number of materials per Company.

I have read the part of
http://www.sommarskog.se/arrays-in-sql.html#iterative that talks about 'The
Iterative Method' but my knowledge of SQL is very limited and I don't know
how to use this code to get what I need.

Can anyone help me?
