I have a question about how to access 'file' with SQL server
In the beginning, I can upload and read file through my content type
in the zope default file system.
Then, after reading Mr. Burton's useful article: HOWTO:Using Archetypes
SQLStorage and Advanced Tips, I decide to change my content type so as
to access a relational database.
I choose MySQL as my testing database.
Eventually, I almost succeeded in transfering this modification, besides
the access problem.
Originally, I can read the file which I save/read in the old content type.
However, I can not read the file any more when I modify the code as :
FileField('file', storage=MySQLSQLStorage(), widget=FileWidget(),),
The error message is showed in the end of this article.
I can sure that I have added the file property -- LONGBLOB -- in the
SQL Server. And, I also can save file into SQL server. But, I do
really have no idea why I still can not read the file after saving it.
I am a Newbie, please help me with your valuable comments and any
resources in the web.
Thank you very much
