Exception while using biginteger column with SUM function --------------------------------------------------------- Key: TEIID-3273 URL: https://issues.jboss.org/browse/TEIID-3273 Project: Teiid Issue Type: Bug Components: Query Engine Affects Versions: 8.7 Environment: Teiid 8.7 and Windows Reporter: Rakesh Balguri Assignee: Steven Hawkins Fix For: 8.7.1, 8.10 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".
