     Posted: 18 Sep 2008 at 7:16pm
 
I have one database field that stores a datetime.  I have another one that stores an integer value (represents minutes).
 
How can I write a formula that takes the datetime, subtracts the integer(minutes), and gives me the new datetime?

you can use this function
 
Dateadd("n",(<integer>*-1),{@tday})
 
where n stands for minutes to be added or subtract
 
(<integer>*-1)  is the no of minutes (table field name)  to be subtracted
 
{@tday} is the date from which the minutes to be subtracted.
 
You can find many more such inbult  functions of crystal reports in chapter 6 "Programming with Crystal Syntax" of  Brians Bischof book " Crystal Reports Encyclopedia"
Thanks

Thanks!  That worked.
 
I was actually playing with Dateadd yesterday but couldn't get it working right.
