Andrej Šmigala created TEIID-5192: ------------------------------------- Summary: Osisoft Translator - selecting ABS on a long value causes NPE Key: TEIID-5192 URL: https://issues.jboss.org/browse/TEIID-5192 Project: Teiid Issue Type: Bug Components: JDBC Connector Affects Versions: 8.12.x-6.4 Reporter: Andrej Šmigala Assignee: Steven Hawkins Running a query such as {code:sql} SELECT LongNum, ABS(LongNum) AS ABSLongNum FROM BQT2.SmallB {code} results in a NullPointerException while translating the results. The type of LongNum column on the datasource is int64. This does not happen with other column types (integer, float, double). When running an equivalent query directly against the Osisoft PI datasource, the correct results are returned and the type of the ABS column is Single (i.e. float). It appears the translator tries to get the ABS value as long, see stacktrace.
