Subject [jira] Created: (GERONIMO-5617) Timestamp precision (scale) openjpa -> Oracle
Date Tue, 21 Sep 2010 10:44:32 GMT
Timestamp precision (scale) openjpa -> Oracle
---------------------------------------------

                 Key: GERONIMO-5617
                 URL: https://issues.apache.org/jira/browse/GERONIMO-5617
             Project: Geronimo
          Issue Type: Bug
      Security Level: public (Regular issues)
          Components: databases, persistence
    Affects Versions: 2.1.4
         Environment: Geronimo 2.14 with JDK 1.5 update 20, on Window / Linux, Database Oracle
10g or 11
            Reporter: Ralf Baumhof


Timestamp precision should be up to 10 up -12 (nano second) with Datatype java.sql.Timestamp.
On inserts to database only 10 up -3 is inserted. 
This is done with rounding at position 10 up -3.

Example - the log lines beginning with a "#" the value of 5551110 is rounded to 12:16:06.006:
