Sorry for my poor English.

When I try to insert a new record, the value of BLOB field of last
record will be deleted. There is value of BLOB field in last record
only.

If I insert one record only and post it by calling ApplyUpdates &
CommitUpdates before to insert a new record. This record's BLOB value
will be saved. If I try to insert the second record, the BLOB field
value of first record will be null.

Yes, I edit records in wwDBGrid (InfoPower's DBGrid), but I call
another form to edit the value of BLOB field.

If I set CachedUpdates to false, all records' BLOB value will be
saved.

Helen, thanks for your reply and help!
