hi all
i'm using postgres 7.3
my problem is i want to build a helper table:
UPDATE studienmodul_summary
SET kategorie = (SELECT kategorie_bezeichnung
if the SELECT gives back just one result row, everthing is easy. my
problem is, there is sometimes more than one result row.
is there a way to concatenate all result rows and insert them in one
field?
any hint is very much appreciated.
thanks
simon
