No, No not for this statement , my group leader tells that rownum is not used so much in applications becouse it can give wrong results sometimes. I do not know if it is correct . I ask you for approve him or not.. Thanks

Consider the following case.
TABLE : DEPT

empid             number,
deptid             number,
deptname        varchar2(30)

primary key (empid, deptid)

now i want to fetch first seven records from a cursor whose deptid is maximum
and empid is minimum. kindly let me know how to write this cursor statement.for example.

SQL> select deptid, empid from dept;

DEPTID EMPID

---------       ---------
        2     94204
        2     94205
        2     94206
        2     94207
        2     94208
        5     94209
        5     94210
        5     94211
        5     94212
        5     94213
        7     94214
        7     94215
        7     94216
        7     94217
        7     94218

15 rows selected.

i want output as following by single query.

DEPTID EMPID

---------      ---------
        7     94214
        7     94215
        7     94216
        7     94217
        7     94218
        5     94209
        5     94210
