One of the embedded services system calendar functions.
For more information about the embedded services calendar functions, see SQL Functions, Operators, Expressions, and Predicates, B035-1145.
DATE expression
DATE AT TIME ZONE expression
A DATE or DATE AT TIME ZONE expression argument for the specified embedded services system calendar function.
You can specify a SELECT CURRENT_DATE or SELECT CURRENT_DATE AT TIME ZONE argument instead of an explicit DATE or DATE AT TIME ZONE expression argument.
TIMESTAMP expression
TIMESTAMP WITH TIME ZONE expression
A TIMESTAMP or TIMESTAMP WITH TIME ZONE expression argument for the specified embedded services system calendar function.
You can specify a SELECT CURRENT_TIMESTAMP or SELECT CURRENT_TIMESTAMP AT TIME ZONE argument instead of an explicit TIMESTAMP or TIMESTAMP WITH TIME ZONE expression argument.
system_calendar_name
An optional system calendar name used to define a different calendar than the one assigned to the current session.
For the definitions of the system calendars, see Data Dictionary, B035-1092.
You do not need to specify a system calendar name for week-related specific times because, for example, the previous Monday for a specified date is the same for all of the calendars.
