Postgresql GROUP_CONCAT equivalent?

Question

I have a table and I\'d like to pull one row per id with field values concatenated.

In my table, for example, I have this:

TM67 | 4  | 32556
TM67 | 9         


        

Answer 1

Try like this:

select field1, array_to_string(array_agg(field2), ',')
from table1
group by field1;
