Daniel John Debrunner closed DERBY-1863.
----------------------------------------
Resolution: Won't Fix
EoD is being dropped from JDBC 4.
> SQL NULL always represented as zero when mapping an INTEGER column to a Java
> int or Integer field using a EOD query object extended from BaseQuery
> --------------------------------------------------------------------------------------------------------------------------------------------------
>
> Key: DERBY-1863
> URL: http://issues.apache.org/jira/browse/DERBY-1863
> Project: Derby
> Issue Type: Bug
> Components: JDBC
> Affects Versions: 10.2.1.6, 10.3.0.0
> Environment: Mustang b98
> Reporter: Daniel John Debrunner
>
> SQL INTEGER column mapped to a Java primitive int field resulted in the filed
> set to zero when the SQL value was NULL.
> This means there is no way to tell if the field was NULL or not. I was
> expecting some error, either at "mapping" time or at exection time.
> SQL INTEGER column mapped to a Java java.lang.Integer field resulted in the
> filed set to zero when the SQL value was NULL.
> Was expecting the field to be set to Java null. Note for VARCHAR columns
> mapped to a String field, the result is Java null when the SQL value is NULL.
> JDBC 4.0 spec seems silent on the expected behaviour for @Select queries and
> the column mapping when the SQL value is NULL.
