Temporal Types and Literals
U-SQL’s built-in temporal types are:
The grammar rules use
Temporal_Type to refer to one of these types.
U-SQL’s temporal types do not have a built-in literal form, but require the standard C# construction mechanisms such as DateTime.Parse() or new DateTime(). Note that these constructions with simple string and number parameters are constant folded (executed at compile time) and thus are similar to a built-in literal.
