Subject [jira] Commented: (DERBY-163) Timestamp formatting
Date Wed, 02 May 2007 17:22:16 GMT

    [ https://issues.apache.org/jira/browse/DERBY-163?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12493150
] 

Daniel John Debrunner commented on DERBY-163:
---------------------------------------------

I think the problem Kathey is seeing is a separate, more serious, bug.
The value being returned to the client is not the correct value, but instead a truncated value.
This bug is for trailing zeros not being displayed.

>                 Key: DERBY-163
>                 URL: https://issues.apache.org/jira/browse/DERBY-163
>             Project: Derby
>          Issue Type: Bug
>          Components: Newcomer, SQL
>    Affects Versions: 10.0.2.0
>         Environment: Windows XP Professional SP1
>            Reporter: George Baklarz
>            Priority: Minor
>
> The timestamp format within Derby contains the following information:
>     yyyy-mm-dd-hh.mm.ss.mmmmmm
> When issuing a CURRENT TIMESTAMP function, it returns
>     yyyy-mm-dd-hh.mm.ss.mmm
> If you do a TIMESTAMP('1988-12-15-17.12.30.123400') it will return
>     1988-12-15-17.12.30.1234
> Is there any particular reason why Derby does not display the zeros at the end of the
field? This may just be just to be consistent with the ISO standards, but if you look at the
example in the manual, it shows:
>   VALUES TIMESTAMP(START_DATE, END_DATE)
>   1988-12-25-17.12.30.000000
> If I try this with a simple table:
> CREATE TABLE TS (A DATE, B TIME);
> INSERT INTO TS VALUES (CURRENT DATE, CURRENT TIME);
> SELECT TIMESTAMP(A,B) FROM TS;
> ij> select timestamp(a,b) from ts;
> 1
> --------------------------
> 2005-03-04 15:13:19.0
> So the 0's are not displayed, except for the first microsecond. The format needs to be
clarified either in the manuals or corrected in the program.
