select replace( replace( replace( replace( 'Test ä ö ü ß', 'ä','ae'), 'ö','oe' ), 'ü','ue'), 'ß','ss' );
Thanks a lot. A wrote this into a user defined function with lower() around the source string, and it works. :-)
CREATE OR REPLACE FUNCTION public.unumlaut(varchar)
RETURNS varchar AS
'select replace( replace( replace( replace( lower($1), \'ä\',\'ae\'), \'ö\',\'oe\' ), \'ü\',\'ue\'), \'ß\',\'ss\' );'
LANGUAGE 'sql' IMMUTABLE STRICT;
Best regards, Robert. :)
