I need to update a blob field via SQL. I am trying this:

Update MyTable
set MyBlobField = :BlobParam where MyTable_ID = :IDParam

How do I assign the value to 'BlobParam'? I can 'LoadFromFile' but I
have it in a memory stream. The Param.Assign wants a TIB_Column, not
a memory stream, and I don't see any .LoadFromStream method.

Thanks
