A B commented on DERBY-2259:
----------------------------
> Apart, any Idea about XML date type for this, currently I had put it as
> typePredNone (I am not
> familiar with XML data type)
typePredNone is the correct value for XML. One is not allowed to search an XML
value directly. The only way to search/query XML values is via use of the
XMLEXISTS() or XMLQUERY() operators.
> DatabaseMetaData.getTypeInfo() SEARCHABLE column returns incorrect
> information for types that cannot be searched.
