When PARSETIMESTAMP is included in a query aggregates in other columns may not be written correctly. Example is as below, sum(first_metric) is rewritten to anon_grp0.agg0 in the query sent to Impala.

Given the schema:
//source
SourceTable
the_attribute string(255),
first_metric long,
second_metric bigdecimal
another_attribute String(255)

//view
VirtualTable
the_attribute string(255),
first_metric long,
second_metric bigdecimal
another_attribute String(255)

// Teiid query
SELECT the_attribute,
cast(
sum(
first_metric
)
/
count(
distinct case when second_metric >= 0 then second_metric end
) as double
) as some_alias,
PARSETIMESTAMP(another_attribute, 'yyyy-MM-dd') as somedate
FROM VirtualTable
WHERE a_filter_val=111
GROUP BY the_attribute, another_attribute

//Query sent to impala
SELECT g_0.the_attribute AS c_0,
cast(
(
anon_grp0.agg0
/
cast(
anon_grp0.agg1 AS bigint
)
) AS double
) AS c_1,
g_0.another_attribute AS c_2
FROM VirtualTable
WHERE a_filter_val=111
GROUP BY g_0.the_attribute, g_0.another_attribute
