Subject [jira] [Updated] (DERBY-3398) Support min/max values for Java types float/double in real/double columns
Date Fri, 15 Feb 2013 07:29:12 GMT

     [ https://issues.apache.org/jira/browse/DERBY-3398?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Dag H. Wanvik updated DERBY-3398:
---------------------------------

    Attachment: derby-3398-5.stat
                derby-3398-5.diff

Uploading patch #5, which implements the deferred check on DB2 limits in soft upgrade mode,
when no lcc is present, cf. discussion above.

The upgrade tests now verify this distinction, cf. the "defer" parameter to Changes10_10#verifyDB2Behavior.

The patch also adds upgrade tests for the ResultSet#updateXXX case.

 Rerunning regressions.

> Derby doesn't support the entire range of valid (finite) values of the Java primitive
types double/float in columns with SQL type DOUBLE or REAL. This appears to be a limitation
that was introduced for compatibility with DB2. There have been some requests on derby-user
that we lift this restriction.
> The restriction is enforced by the methods normalizeREAL() and normalizeDOUBLE() in org.apache.derby.iapi.types.NumberDataType.
