Still don't know how to build this string ? - Mailing list pgsql-sql

Hello there

I have still the same problem. Any help would really be appreciated !
Thanks ... jr

Is it possible (and I think it is) to do the following :

I have a table with diameters and types. I need to build a comma separated
string.

typ       diam
01        800
01        840
01        870
01        1120
02        760
02        780
02        800
02        900
03        1200
03        1234
03        1352

select diam from zylinder where typ='01'

should produce the string "800,840,870,1120"
