I have a query where one field is a blob - different documents saved in binary form.
The blobfield is marked as non visible in the fielddefinition of the query, only fields like the
filedate and size of the saved document are shown in a grid. My first question is: Does the blob go
over the wire if only the grid is shown. Or is it only extracted from the database when it is really
needed.
My second question is about the "size" of the blob when defining the field upon creation of the
database. Is is necessary to carefully set this value to a certain value. If so, how do I calculate
it.
