Body
I work with public StackOverflow dump and have everything stored in MySQL. Now, I want to perform some analyses using Java and MyBATIS. For some of these I need to extract timeseries for a user, or a particular question etc. So for this, lets say posts and their timestamps, I have a MyBatis query: <pre><code> <select id="GetAllPostsTimeStamps" resultType="java.util.Date"> SELECT creationDate from posts </select> </code></pre> which hands the timestamp data to MyBatis ResultHandler, where I do this transformation: <pre><code>@Override public void handleResult(ResultContext context) { TimeZone tz = TimeZone.getTimeZone("UTC"); TimeZone.setDefault(tz); Date tstamp = (Date) context.getResultObject(); XMLGregorianCalendar xmlTstam = Tstamp.makeTimestamp(tstamp.getTime()); ...etc... } </code></pre> I really need to use <code>XMLGregorianCalendar</code> because all my downstream logic relies on this type. Is it possible to tell MyBatis with its handlers feature to make transformation of SQL datetime to XMLGregorianCalendar internally (i.e. I will code the handler only once), so I will get proper timestamps out of it everytime I need? Editing to add more clarity. So, when I save java objects with <code>XMLGregorianCalendar</code> fields into DB (MySQL datetime type) I use an implementation of MyBatis handler: <pre><code>XMLGregorianCalendarDateTypeHandler implements TypeHandler<XMLGregorianCalendar> ... </code></pre> which I specify in the <code>INSERT</code> query like this: <pre><code> ..., #{creationDate, javaType=javax.xml.datatype.XMLGregorianCalendar, jdbcType=TIMESTAMP, typeHandler=...XMLGregorianCalendarTypeHandler},... </code></pre> is there a way to specify the backward transform handler for <code>SELECT</code> type queries?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
