Thomas,
"I must admit that the blob input parameter is only used within an INSERT
INTO
statement then, inserting into a column which is based on subtype 0, so
independent what blob data is coming through, the inserted blob is always
stored in a subtype 0."

huh??

IN the statement
update tbljobschedule set notes='this is a blob' where jobind=3
do you do something like
update tbljobschedule set notes SUB_TYPE 1 SEGMENT SIZE 80='this is a blob'
where jobind=3
??? How do you do this?
