SQL Help for Date Range display

Question

Gurus,
I have a sql statement like
select MIN(HIREDATE), MAX(HIREDATE) FROM EMP WHERE DEPTNO = 30My output looks like
MIN(HIREDATE)     MAX(HIREDATE)
12/30/1998        12/30/2001Based on the values of MIN(HIREDATE) , MAX(HIREDATE) values
I need a SQL to generate the output like
12/30/1998
1/30/1999
2/28/1999
until Max(HIREDATE) value
In Feb we dont have 30th day, In that case take the last day of the month.
Thanks for great help
