> In SQL standard 2011 part 7 value expression, it defines the SQL syntax for
> explicit ROW value constructor to allows all the valid value expreesion:
> {code:sql}
> <row value constructor> ::=
> <common value expression>
> | <boolean value expression>
> | <explicit row value constructor>
> <common value expression> ::=
> <numeric value expression>
> | <string value expression>
> | <datetime value expression>
> | <interval value expression>
> | <user-defined type value expression>
> | <reference value expression>
> | <collection value expression>
> <explicit row value constructor> ::=
> <left paren> <row value constructor element> <comma>
> <row value constructor element list> <right paren>
> | ROW <left paren> <row value constructor element list> <right paren>
> | <row subquery>
> <row value constructor element> ::=
> <value expression>
> {code}
> I also tried the PostgreSQL 9.6 for the query:
> {code:sql}
> create table t1(
> f0 int,
> f1 varchar(20)
> );
> insert into t1 values(1, 'abc');
> -- select row(t1.f0 + 1, t1.f1) from t1; -- outputs (2, abc)
> {code}
