[Zope] z Sql method and data type on insert...

Hi all, I want to use formulator + z sql method to insert data to a Mysql db. Got the form setup, but I have some fieldS that are "textarea" field type in the form, blob in my DB. The problem is that in the sql insert command, the following: "<dtml-sqlvar instructions_recette type="blob">" is not recognized by the Z sql method. Also, what are the valid data type for zsql method? The only one I could find where string or int.
