I need help with iterating the records of a database table and populating a field with the concatenation of 2 fields in the table.

I currently have a table with the Following fields and records:

Class_ID, Class_Day, Start_Time, End_Time
"GMS-557-01","T","08:30AM","10:50AM"
"GMS-557-01","TH","08:30AM","10:50AM"
"GMS-595Y-01","T","1:00PM","2:50PM"
"GMS-610-01","M","08:30AM","11:50PM"
"GMS-623-01","M","01:00PM","05:50PM"
"GMS-623-01","W","03:00PM","04:50PM"
"GMS-623-01","F","01:00PM","02:30PM"
"GMS-649-01","W","08:00AM","09:50AM"
"GMS-649-01","F","08:00AM","09:50AM"
"GMS-710-01","TBA","08:00AM","09:50AM"

After running a stored procedure preferably or a vb2005 sub procedure in the code of my asp.net 2.0 project I need to have the day(s) that each class meets concatenated and entered in the Class_Days field.

Class_ID, Class_Day, Start_Time, End_Time, Class_Days
"GMS-557-01","T","08:30AM","10:50AM","T,TH"
"GMS-557-01","TH","08:30AM","10:50AM","T,TH"
"GMS-595Y-01","T","1:00PM","2:50PM","T"
"GMS-610-01","M","08:30AM","11:50PM","M"
"GMS-623-01","M","01:00PM","05:50PM","M,W,F"
"GMS-623-01","W","03:00PM","04:50PM","M,W,F"
"GMS-623-01","F","01:00PM","02:30PM","M,W,F"
"GMS-649-01","W","08:00AM","09:50AM",,"W,F"
"GMS-649-01","F","08:00AM","09:50AM",,"W,F"
"GMS-710-01","TBA","08:00AM","09:50AM","TBA"
