How to make columns in the select list dynamic

Question

Hi
I need to make columns in the select query dynamic.I have three tables.Table 1 contains master information lets say name of group(A group consists of members of various skill sets) and its period(A group is of specific period lets say for 18 months).Table 2 contains different skill sets corresponding to a group i.e there is one to many relationship between table 1 and table 2.Table 3 contains months information of skill sets.For example if skill set 1 is required for 5 months then there will be 5 rows(for each month) in table 3 corresponding to a skill set i.e there is again one to many relationship between table 2 and table 3.Tabale 3 will also contain man month value for perticular month.I need to show all the periods of a group and its sum of man month value for all skill sets.
If group1 is of 6 months (starts nov2006 and ends Apr2007) and has 5 skill sets then there will be one entry in table 1 and 5 entry in table 2(For skill set).For each entry in table 2 there will be 6 entry in table 3(for each month).I need to write a query which would display
Group name   nov2006   dec2006   jan2007   feb2007  mar2007 apr2007
Gr1             10          15      21      17         18         22--These are sum of man month of all skill set for a particular groupIf Gr 2 is of 9 months then it would disply all the information in respective months.i.e for group 2 nine months information and group 1 six months information
Pls help
Thanks in advance

From your requirement, we understand that you want to make Rows in table 3 as Columns.
