Subject [jira] Created: (DERBY-4810) setTimestamp() methods don't agree on trailing zeros
Date Wed, 22 Sep 2010 13:10:33 GMT
setTimestamp() methods don't agree on trailing zeros

                 Key: DERBY-4810
                 URL: https://issues.apache.org/jira/browse/DERBY-4810
             Project: Derby
          Issue Type: Bug
          Components: JDBC
    Affects Versions:
            Reporter: Knut Anders Hatlen
            Assignee: Knut Anders Hatlen
            Priority: Minor

With the statement


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.
