Tuple Expression |
Constructors.md |
tuple_expr ::= '(' (expr',')* ')'
The last comma is optional.
However, in order to specify a 1-tuple, you have to use (e,).
That being said, 1-tuples will be removed in a future version of Impala.
A tuple (e_1, ..., e_n) has type (E_1, ..., E_n) where e_i is of type E_i.
All elements are evaluated from left to right and packed into a tuple value.
let x = (true, 23, 42.f);
