Jesus Camacho Rodriguez closed CALCITE-877.
-------------------------------------------
Resolved in release 1.5.0 (2015-11-10)
> Allow ROW as argument to COLLECT
> --------------------------------
>
> Key: CALCITE-877
> URL: https://issues.apache.org/jira/browse/CALCITE-877
> Project: Calcite
> Issue Type: Bug
> Reporter: Julian Hyde
> Assignee: Julian Hyde
> Fix For: 1.5.0
>
>
> We would like to build multisets of records, for instance all of the
> employees in a department: {code}SELECT deptno, COLLECT(ROW(ename, salary))
> AS emps
> FROM emp
> GROUP BY deptno{code}
> Standard SQL only allows ROW inside a table constructor (i.e. a VALUES
> clause). A workaround is to create a user-defined type (CREATE TYPE; see
> http://www.oracle-developer.net/display.php?id=306) but it would be
> preferable to be able to create rows of anonymous type, so that the above
> SELECT statement just works.
