Convert date to ticks in SQL Server

Does anyone know how to convert a DATETIM开发者_StackOverflow社区E COLUMN to TICKS in SQL Server?

If you are trying to have t-sql convert a value to ticks that can be compared with the "same" value created in .NET it will not work. A DateTime data type in SQL Server only has a precision of about .003 seconds (actually values are rounded to .000, .003 or .007) or 10^-3 whereas a DateTime data type in .NET has a precision of 100 nanoseconds (10^-7).
