Hi all,
I have been trying to use the blob functionality within dbforms.
And apart from my problems it works ok, but not quite.
I can upload and download images (blobs).
I use MySQL LONGBLOB....
So far so good....
Now for my problems :
1) It seems the maximum length is about 64 KB, files larger than this give
me a 'Check if uploaded file(s) exceeded allowed size'.
ok, i can understand that, but where to put that allowed size ??
DBFORMS ? Where ?? maybe LONGBLOB in the XML file ??
MySQL : Should not matter, as its a LONGBLOB....
2) How to determine whether a blob element is empty or not in JSP.
I would like to blend in the (almost) standard paperclip if a
attachment
is present in a record. So I would like to do something like :
<% if (currentRow_table.get("blob_1") == null) { %>
ATTATCHMENT...... present
<% } else { %>
sorry, no attachment
<%>
Unfortunatly, above always evaluates to true.... perhaps something like
' == emptyblob()'
/me confused
Thanx,
Fred
