Subject [jira] [Commented] (TORQUE-355) Implement millisecond support for MySQL timestamps
Date Mon, 11 Mar 2019 16:21:00 GMT

    [ https://issues.apache.org/jira/browse/TORQUE-355?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16789733#comment-16789733

Georg Kallidis commented on TORQUE-355:

1) schema->sql 

If setting in schema.xml 
the sql is already set correctly 

datetime DATETIME(6) NOT NULL{code}

Note: I am not sure, if _scale_ should not be the proper attribute, but changing this nothing
happens - it's not used in mapping..

But setting the _default_ for a column to a value, is not quite as easy (in schema.xml).

At least _*two patterns*_ are applied in this case in the mapping in
org.apache.torque.templates.transformer.sql.SQLModelTransformer.getDdlSql(Column, ControllerState){code}
for _default_ values 

1. extracting for any default (DEFAULT_DATE_FORMAT)

2. setting platform specific


Changing the latter e.g. in
 might not be sufficient. Depending on the size different patterns should be applied as the
DEFAULT_DATE_FORMAT might not be parsable.-> add a size parameter to both mappers ?


 2) schema -> java

TODO  ... ?

3) Last not least

As far as I can see java 1.8 is now standard in Torque trunk - may be all Date interfaces
should be migrated to DateTime using java.time ?

>          Issue Type: Improvement
>          Components: Runtime, Templates, Test Project
>    Affects Versions: 4.0
>         Environment: MySQL
>            Reporter: Thomas Vandahl
>            Priority: Major
> MySQL 5.6.4 and up expands fractional seconds support for TIME, DATETIME, and TIMESTAMP
values, with up to microseconds (6 digits) precision. This needs to be supported.
