i am getting the error "Adding a value to a 'datetime' column caused overflow."   when I try and run this statement.  DATEADD(dd, - 365, p.LASTMISSEDAPPT) < pl.PLDATE.  how can I change DATEADD(dd, - 365, p.LASTMISSEDAPPT) to avoid this.

Thanks

what are values in the 2 fields? you might hit min value of date ...what about:
 p.LASTMISSEDAPPT < dateadd(dd, 365, pl.PLDATE)





resp:



p.LASTMISSEDAPPT < dateadd(year, 1, pl.PLDATE)

Waht type is p.LASTMISSEDAPPT?

If p.LASTMISSEDAPPT is a float "representing" a date, then this value is likely
to be too high. If it exceeds 2936549 you will get an out or range error
(or similar error). If it represents a date, you should cast it to a
datetime.

Example of a field is the value of the fields could be 9/7/2010.  It still does it when I cast the value as datetime 101.  thanks

There are any rows in your data table with this value in that field?

'1900-01-01 00:00:00'

which is the minimum year value (1753);

going 1 year back will indeed result in that error.
please try what I suggested first, changing to do the "dateadd(year,1 ,... )"

You might look for this to find the problem data:

Select * from yourtable
  Where IsDate(p.LASTMISSEDAPPT) = 0

maybe the minimum SQL DateTime Value is 1/1/1753. Substruct one year to fields with the value you have mentioned ("3/2/1753") throw the exception
