Hello,
I have the error ORA-00979 : not a GROUP BY expression, when i try to execute this request :

SELECT T.A_RO, A.A_ANCIEN_RO, T.A_NOM, T.A_PRENOM, I.N_NUM_SEQ AS N_NUM_SEQ_INF, T.N_NUM_SEQ AS N_NUM_SEQ_TIERS, I.A_NUM_PV, TO_CHAR(I.D_DATE_HEURE, 'DD/MM/YYYY')"D_DATE_HEURE", I.A_SERVICE_VERB, I.A_CODE_NATINF
FROM ...
WHERE ...
GROUP BY T.A_RO

I think you don't need the FROM and WHERE clauses (i hope).

Thank you very much.

The Group By functionality seems to want you to mirror the items in the Select statement. If you put every field in the Group By that you put in the Select it might work.
