             Summary: Decimal number got converted to Integer
                 Key: TEIID-3182
                 URL: https://issues.jboss.org/browse/TEIID-3182
             Project: Teiid
          Issue Type: Bug
          Components: Query Engine
    Affects Versions: 8.8
         Environment: Teiid 8.8.1 with hive driver (hortonworks 2.0)
            Reporter: Ivan Chan
            Assignee: Steven Hawkins


Teiid engines converts  value 1000.0 to 1000 and it doesn't keep the original data type.

My original SQL:

select ("meat_sqft" / 1000.0) as "calcField2" from "HDP20_default"."store" group by ("meat_sqft" / 1000.0)

and Teiid translated it to:

SELECT v_0.c_0 FROM (SELECT (g_0.meat_sqft / 1000) AS c_0 FROM HDP20_default.store AS g_0) AS v_0 GROUP BY v_0.c_0 ORDER BY c_0 LIMIT 200001

(g_0.meat_sqft / 1000)  field returns Integer instead of decimal.

However, if I use 1000.1 instead and it would work.

Original SQL:

select ("meat_sqft" / 1000.1) as "calcField2" from "HDP20_default"."store" group by ("meat_sqft" / 1000.1)

And teiid translated it to:

SELECT v_0.c_0 FROM (SELECT (convert(g_0.meat_sqft, bigdecimal) / 1000.1) AS c_0 FROM HDP20_default.store AS g_0) AS v_0 GROUP BY v_0.c_0 ORDER BY c_0 LIMIT 200001

I believe both 1000.0 and 1000.1 should have consistent behavior.
