Need to support floating point primary keys
-------------------------------------------
Key: OPENJPA-214
URL: https://issues.apache.org/jira/browse/OPENJPA-214
Project: OpenJPA
Issue Type: Bug
Components: jdbc
Affects Versions: 0.9.7
Reporter: Kevin Sutter
Fix For: 0.9.8
Dain first reported this problem on the dev mailing list:
http://www.nabble.com/Float-primary-key--tf3557137.html
>My response:
>Okay, I looked at the spec a bit closer and it looks like we need to allow for
>floats as primary keys:
>"The primary key (or field or property of a composite primary key) should be
>one of the following types:
>any Java primitive type; any primitive wrapper type; java.lang.String;
>java.util.Date;
>java.sql.Date. In general, however, approximate numeric types (e.g., floating
>point types) should
>never be used in primary keys."
>Although the spec clearly recommends against the use of floating points,
>floats are a primitive type (or the Float wrapper) and need to be allowed.
>With no >special "AllowStupidApproximatePrimaryKeys" flag. :-)
>Am I trying to read too much into the spec or Dain's request? This seems to
>be something that we need to support.
>>Abe's response:
>>Given the spec section you quoted, you're definitely right. It's something
>>we need to support.
