source type are LOBs. Therefore, you have used LOB file reference variables

to assign the contents of the file into the UDT column. You have not used
|

|
the cast function to convert values of BLOB type into your e-mail type. This
|

is because DB2 allows

you to assign values of the source type of a distinct type to targets of the

distinct type.</p>
