Subject [jira] [Commented] (HIVE-22706) Jdbc storage handler incorrectly interprets boolean column value in derby
Date Fri, 10 Jan 2020 11:17:00 GMT

Zoltan Haindrich commented on HIVE-22706:
-----------------------------------------

well; after some digging my hypothesis have confirmed; that datanucleus is pulling these Y/N
into play...the translation is done at several places including [this|https://github.com/datanucleus/datanucleus-rdbms/blob/6f01a33e7d514f90775ddd7d3d7bfe77303e787b/src/main/java/org/datanucleus/store/rdbms/mapping/datastore/CharRDBMSMapping.java#L332].

I played with the idea to try to reuse the parts which are doing this kind of conversions
; but they are kinda deeply tied to a plugin system inside datanucleus and it would look strange....

So I think the best course of action ; to have our sysdb show rational values is to interpret
the char 'N' as false...

> in case the column value is false ; the storage handler interprets it as true
