Subject [jira] Updated: (DERBY-4810) setTimestamp() methods don't agree on trailing zeros
Date Wed, 22 Sep 2010 13:16:34 GMT

     [ https://issues.apache.org/jira/browse/DERBY-4810?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Knut Anders Hatlen updated DERBY-4810:
--------------------------------------

    Bug behavior facts: [Embedded/Client difference]

Marking as an Embedded/Client difference too, since the client driver will always use the
format of setTimestamp(int,Timestamp,Calendar).

> PreparedStatement.setTimestamp(int,Timestamp) and PreparedStatement.setTimestamp(int,Timestamp,Calendar)
don't agree on what to do with trailing zeros in the nanosecond component. The method that
doesn't take a Calendar argument, removes trailing zeros. The method that takes a Calendar
object appends zeros so that the nanosecond component always has nine digits. (Both methods
have a special case when nanoseconds is zero, and they agree on adding just a single zero
after the decimal point in that case.)
> The format used by PreparedStatement.setTimestamp(int,Timestamp) matches what java.sql.Timestamp.toString()
returns (in fact, it uses Timestamp.toString() internally to produce the string representation),
and I think it would be reasonable to use that format for both the methods.
