concatenating the two column values of different rows into one in teradata

问题

I have table with the below data in teradata database

cstmr_id | name 1 | aaaaaa 1 | bbbbbb 2 | cccccc 2 | dddddd

I want the output to be like 1 | aaaaaa,bbbbbb 2 | cccccc,dddddd

The output should be written to another table. All this needs to be done in teradata.

Thanks in Advance, Nikhila

What's your Teradata release? Are XML services installed?

SELECT cstmr_id,  
   RTRIM(XMLAGG(name || ','
          ORDER BY name
        ) (VARCHAR(1000)),',')
FROM tab
GROUP BY 1
