Hi,

I have column which is of "BigInteger" type and when I am trying to execute an SQL which contains the SUM function I am getting the following exception.

The following is the SQL:

SELECT SUM(age) FROM test

My understanding is that the sum of all the BigInteger's is not fitting in the size of the BigInteger and Teiid is trying to convert it into a BigDecimal and end up in an exception.

How to fix this problem? Do we have a woraround for this?

Caused by: org.teiid.core.TeiidRuntimeException: TEIID20001 The modeled datatype biginteger for column 0 doesn't match the runtime type "java.math.BigDecimal". Please ensure that the column's modeled datatype matches the expected data.
