i want to select mdata type of field eg visualState in xtk:workflow, how to specify this attribute in querydef call
eg
var query = xtk.queryDef.create(
<queryDef schema={schemaName} operation="select" lineCount="1">
<select>
<node expr="visualState" alias="@visualState"/>
</select>
<where>
<condition expr={condition} />
</where>
</queryDef>
is this correct or is there special syntax to select such elements.
my javascript activity is hanging when i execute this query. it works fine when some simple attribute or element is specified for selection.
Solved! Go to Solution.

Hi Priyanka,
Your syntax is correct, but you were unlucky with your test.
If you replace visualState by the other memo (mdata) field in xtk:workflow, called data, it works fine:
<node expr="data" alias="@data"/> |
For me as well the workflow hangs when I use;
<node expr="visualState" alias="@visualState"/>
It seems the binary data (an image) can't be manage by a standard queryDef, probably you must use buffer manipulation to manage image.
