Hy,
i'm looking for a solution to get this table dynamicaly in that resultset:
SELECT r_dbrid, r_kategorie AS column_name, r_descr AS value FROM
recnokeyword WHERE r_dbrid=X
r_dbrid | r_kategorie | r_descr
----------+-------------+------------
14725737 |material | Alu Sorte1
14725737 |farbe | Blau
14725737 |gewicht | 100 kg
---->
material | farbe | gewicht
----------+-------------+------------
alu sorte 1|blau | 100kg
----> the number of columns depends on data.
is there is a simple solution for that?
have you ruled out the appropriate contrib module?

yes, but that function requires a return type -> so i has to know how
many columns. also the column description ist defined by data but by
return type.
(
SELECT * FROM crosstab('...', '...')
AS ct(row_name text, extra text, cat1 text, cat2 text, cat3 text, cat4 text);
This will produce a result something like:
<== value columns ==>
row_name extra cat1 cat2 cat3 cat4
)
