insufficient privileges using dbmd_sql : I have a PLSQL code using dbms_sql package. For example it starts with sequence creation.

    request:= 'CREATE SEQUENCE ' || utilisateur || '.' || 'seq_fusion_table
                    MINVALUE 1
                    START WITH 1
                    INCREMENT BY 1';
    dbms_sql.parse(curseur_ref, request, dbms_sql.native);
    response := dbms_sql.execute(curseur_ref);  

I have an error :

    ORA-01031: insufficient privileges

I thought the user could not use dbms_sql so I sent this request :

    GRANT execute on DBMS_SQL to user;
    commit;

And just to be sure I sent the creation request without using dbms_sql and indeed the user has the right to create sequences.

What should I do to get rid of this insufficient privileges error ?
