[jira] [Reopened] (SOLR-4978) Time is stripped from datetime column when imported into Solr date field

["Bill Au (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/SOLR-4978?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Bill Au reopened SOLR-4978:
---------------------------


setting convertType=false is a workaround for my problem.  But the bug still exists when convertType is set to true.  DIH should not call ResultSet.getDate() for solr date field because ResultSet.getDate() returns a java.sql.Date which has not time portion.  Since sold date field does have a time portion, DIH should call ResultSet.getTimestamp().

> I discovered that all dates I imported into a Solr date field from a MySQL datetime column have the time stripped (ie time portion is always 00:00:00).
> After double checking my DIH config and trying different things, I decided to take a look at the DIH code.
> When I looked at the source code of DIH JdbcDataSource class, I discovered that it is using java.sql.ResultSet and its getDate() method to handle date field. The getDate() method returns java.sql.Date. The java api doc for java.sql.Date
> http://docs.oracle.com/javase/6/docs/api/java/sql/Date.html
> states that:
> "To conform with the definition of SQL DATE, the millisecond values wrapped by a java.sql.Date instance must be 'normalized' by setting the hours, minutes, seconds, and milliseconds to zero in the particular time zone with which the instance is associated."
> I am so surprise at my finding that I think I may not be right.  What am I doing wrong here?  This is such a big hole in DIH, how could it be possible that no one has noticed this until now?
> Has anyone successfully imported a datetime column into a Solr date field using DIH?
