Object with Long or Decimal got initial zero value while database field is null
-------------------------------------------------------------------------------
Key: DBUTILS-42
URL: https://issues.apache.org/jira/browse/DBUTILS-42
Project: Commons DbUtils
Issue Type: Improvement
Affects Versions: 1.1
Environment: JDK 5.0, MSSQL 2000
Reporter: Matt Jiang
While I use dbutil1.1, I got a big different implementation betweeb 1.0 and 1.1.
Given a Java object, it has a property with Long data type; mapping to
database, its table field datatype is bigint.
If it has a record and its value is null.
In 1.0 implementation, if I load entity, then we can see the property in Java
object is also null.
But in 1.1 implementation, the Java object will got a Long object with 0 inside.
This behavior change does big impact if I upgrade from 1.0 to 1.1. It might
make application logic fail because origional null status now become a Long(0)
value to map to null value in database.
I suggest to change it back. If null value in database, then mapped Java object
should be null as well, not new a Long(0) to be a initial value.
