Adding a value to a 'datetime' column caused overflow in where part of query (ok in select)

Asked by louise_8 in MS SQL Server, SQL Server 2008

Tags: datetime, sql

Getting this error

'Adding a value to a 'datetime' column caused overflow.'

when Im trying to add 1 or 15 years to a datetime field. When I call the code in the select part of the query it works, however in the where part it returns the error.

If I hardcode the start date ( tbPurchaseItem.dtStart) to '2007-04-10 00:00:00.000' which is the first records value it works.

Any ideas please?
