Hi,

why this doesnt workIt does work, for certain requirements.
You never explained what your requirements are, so nobody knows it it works for your requirements or not.
You didn't provide the results you want from the new set of sample data, so it makes it very hard to guess.
Instead of key, you may need to use "DENSE_RANK ... ORDER BY key" in the START WITH and CONNECT BY clauses.
For example:
WITH     got_d_rank     AS
     SELECT     profile
     ,     key
     ,     value
     ,     DENSE_RANK () OVER ( PARTITION BY  profile
                               ORDER BY          key
                       )      AS d_rank
     FROM     target
SELECT     profile
     ||
     SYS_CONNECT_BY_PATH ( key || '-' || value
                   )     AS txt
FROM     got_d_rank
WHERE     CONNECT_BY_ISLEAF     = 1
START WITH     d_rank     = 1
CONNECT BY     d_rank     = PRIOR d_rank + 1
     AND     profile     = PRIOR profile
;Sorry, I can't test this now.
Repeat: this is just a guess, based on very little information.
