Roman Churganov updated CALCITE-4108:
-------------------------------------
Description:
running a query like :
{{select tp.o, MAX( tp.n )}}
{{ from tp join o on tp.o = o.k}}
{{ group by tp.o}}
type of tp.n in Schema is FLOAT, value of tp.n returned from table is of type
java.lang.Float, Calcite makes grouping internally and get error
{{java.lang.ClassCastException: java.lang.Float cannot be cast to
java.lang.Doublejava.lang.ClassCastException: java.lang.Float cannot be cast to
