I am receiving this error when I run the following query:

SELECT CallDetail.callTime +  CAST(CallDetail.actionCode AS INTERVAL
HOUR) AS switchLocalTime
  FROM CallDetail
 WHERE CallDetail.mdn = '1231231234'
   AND switchLocalTime > timestamp '2002-12-21 00:00:00'
   AND switchLocalTime < timestamp '2002-12-21 23:59:59'

The error is:

7453: Interval field overflow.

The really strange thing is that sometimes the query works without error. The callTime column is of type timestamp and the actionCode column is of type smallint.

Anyone have any ideas?

Thanks,

John
