Subject [jira] Commented: (DERBY-2602) TIMESTAMP value is truncated when return to client
Date Thu, 15 Nov 2007 13:32:43 GMT

    [ https://issues.apache.org/jira/browse/DERBY-2602?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12542771
] 

Mayuresh Nirhali commented on DERBY-2602:
-----------------------------------------

A quick look at client/amt/PreparedStatement:setTimestamp(int parameterIndex, java.sql.Timestamp
x) showed following comment,

         setInput(parameterIndex, x);
                // once the nanosecond field of timestamp is trim to microsecond for DERBY,
should we throw a warning
                //if (getParameterType (parameterIndex) == java.sql.Types.TIMESTAMP &&
x.getNanos() % 1000 != 0)
                //  accumulateWarning (new SqlWarning (agent_.logWriter_, "DERBY timestamp
can only store up to microsecond, conversion from nanosecond to microsecond causes rounding."));


There seems to be some reason for trimming here. Before going further, I would like to know
if anyone knows why it was done this way ????

> In ParameterMappingTest   I see the following differences between embedded and client.
 Client is truncating the TIMESTAMP value.  Look for this bug number in the test for reproduction.
>  case java.sql.Types.TIMESTAMP:
>             if (param == 2)
>                 if (usingEmbedded())
>                     assertEquals("2004-03-12 21:14:24.938222433", val.toString());
