Hi,
Is current_date a function? It's a bit puzzling to me since there are no parentheses after it, i.e.
SELECT current_date;
And not
SELECT current_date(); -- syntax error
It, and the others like it, behave as functions. They don't require parentheses because the SQL standard
defines them without parentheses.
How come `current_date` has no parenthesis but `clock_timestamp()` does?
clock_timestamp isn't standard defined and unless the standard forces us to do otherwise function invocation requires parentheses.
