    <p>I am making my first migration script that involves the use of the Groovy/Grails DSL. It looks like this:</p> <pre><code>import my.package.MyObject import my.package.MyObjectUtil import javax.xml.bind.DatatypeConverter databaseChangeLog = { changeSet(author: 'wheresjim', id: '1387238199-1') { comment {'Sets the timestamp in each MyObject where null using the message text'} grailsChange { change { MyObjectUtil myObjectUtil = new MyObjectUtil() def criteria = MyObject.where { isNull("timestamp") } def PAGESIZE = 10 int numRows = criteria.count() int pages = Math.ceil(numRows / PAGESIZE) (pages..0).each { page -&gt; int offset = PAGESIZE * page + PAGESIZE def data = criteria.list(offset: offset, max: PAGESIZE, sort: 'id', order: 'asc') data.each { MyObject myObject -&gt; Date timestamp = new Date(0L) try { def thisMessage = myObjectUtil.createMyObjectFromMessage(myObject.messageText) String dateStr = thisMessage.messageIdentification?.timestamp timestamp = dateStr ? DatatypeConverter.parseDateTime(dateStr).getTime() : timestamp } catch (Exception e) { // Do nothing, this will be logged in the finally which catches another error condition } finally { if (timestamp == new Date(0L)) { log.warn "Error attempting to set timestamp in MyObject ${myObject.id}, setting to $eventDateTime" } } myObject.timestamp = timestamp myObject.save(flush: true) } log.warn "Updated ${myObject.id}" } } } } } </code></pre> <p>The <code>MyObject.messageText</code> is a clob in the database, and to my knowledge, there has been no effort to lazily load it.</p> <p>I should note that this exact script works (it can find the clob text) using the grails console plugin on the app.</p>

    1. COAs a generic advice, try to execute a more simplified version first, maybe it is only some simple difference between the two execution environments.

    2. COI actually had, at one point I was just trying to log the value of the clob field.

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.
