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

Hope below Oracle query will work.

Select First_column,LISTAGG(second_column,',') 
    WITHIN GROUP (ORDER BY second_column) as Sec_column, 
    LISTAGG(third_column,',') 
    WITHIN GROUP (ORDER BY second_column) as thrd_column 
FROM tablename 
GROUP BY first_column
