If you tell me how you call I may be able to see how it comes back.

Issue is the same with DECIMAL data type.

Multiplying two columns in CASE statement overrides pushdown (Impala) --------------------------------------------------------------------- Key: TEIID-3937 URL: https://issues.jboss.org/browse/TEIID-3937 Project: Teiid Issue Type: Bug Components: JDBC Connector Affects Versions: 8.12.4 Environment: Ubuntu Trusty Reporter: Don Krapohl Assignee: Steven Hawkins In the Impala translator, pushdown doesn't happen when two columns are multiplied in the THEN portion of a CASE statement with decimal data type. //this should push down but does not CASE WHEN column1 IS NOT NULL THEN column1 * column2 ELSE column3 END //but you can multiply the columns by a constant and it will push down CASE WHEN column1 IS NOT NULL THEN column1 * 34567 ELSE column3 END //or CASE WHEN column1 IS NOT NULL THEN 34567 * column2 ELSE column3 END //or casting to consistent datatypes with DECIMAL output CASE WHEN column1 IS NOT NULL THEN cast(column1 as DECIMAL ) * cast(column2 as DECIMAL ) ELSE cast(column3 as DECIMAL ) END //BUT output it as double with the cast statement above changed and it does push down (so floating point works) CASE WHEN column1 IS NOT NULL THEN cast(column1 as double ) * cast(column2 as double) ELSE cast(column3 as double) END Source data types: Column1 is DECIMAL Column2 is BIGINT/LONG Column3 is DECIMAL Output column is DECIMAL
