Oracle to SQL2005 DATETIME field overflows in SSIS

Question

I\'m importing data from Oracle to SQL Server 2005 using SSIS. I think the datetime fields in Oracle are stored to a higher precision than SQL Server 2005 \"DATETIME\" fields wi

Answer 1

The issue in this is that SQL Server is limited in what dates are valid (January 1, 1753, through December 31, 9999), while Oracle dates from January 1, 4712 BCE through December 31, 9999. So any date in Oracle less than January 1, 1753 will overflow the datetime sql server datatype.

If you move up to Sql 2008 you can use Datetime2 type to help with this issue as that has valid dates from 0001-01-01 through 9999-12-31.
