A datetime in MS-SQL Server has different components like day, month, hour or minute among others. If you need to extract one of them.
select getdate() original_value,
datepart(hour, getdate()) hour,
datepart(minute, getdate()) minute,
datepart(day, getdate()) day,
datepart(month, getdate()) month
original_value |
hour |
minute |
day |
month |
