Example:
I have a table name A and have three column name OVER_DUE_DATE_TIME(date/time), DUE_DATE_TIME(date/time) and DURATION(Integer, in hours).
I need to do this validation: DUE_DATE_TIME + DURATION <= OVER_DUE_DATE_TIME
If the validation is wrong then should prompt the user error message.
May I have this solution in C# !!
Thanks in advance !!
