[jira] [Issue Comment Edited] (SQOOP-456) Generated Java class does
not distinguish date and timestamp in Oracle DB
[ https://issues.apache.org/jira/browse/SQOOP-456?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13229473#comment-13229473 ]

Hi Arvind,
Thanks for your comment. I think that we would need to introduce a new option something like "--mapDateToTimestamp". In fact, this is the property that Oracle provides for this particular problem. By default, we could set "--mapDatetoTimestamp" to true so that backward incompatibility wouldn't be introduced.

> In genereated Java class, both date and timestamp are considered as timestamps. For examples, the following getter method is generated for a date column:
> {code:xml}
> public void readFields(ResultSet __dbResults) throws SQLException {
> this.__cur_result_set = __dbResults;
> this.DATA_COL0 = JdbcWritableBridge.readTimestamp(1, __dbResults);
> }
> {code}
> This happens because both date and timestamp is labeled as Types.TIMESTAMP by ConnManager. The fix seems straightforward. In ClassWriter, the new method getColTypeNamesForTable introduced by Bilung at SQOOP-352 should replace getColTypes().
