Where are these properties on MySQL?

[Henrique Lobo Weissmann]

Hi,
we are migrating our Access database to MySQL. The process is going all right, but I have some doubts.
Here we are accessing our MySQL database (and Access too) using ADO.
When using ADO with Microsoft Access, we could check if the field was required or not just geting the key "required" inside the property Properties of the Field object.
When accessing our new MySQL database using ADO, we couldn´t find this property. Does it exists?
(I know that we could just verify if the field is required or not checking if it can accept the NULL value. But this is not the case)

Another doubt: in Microsoft Access tables, we have the label property. Does something similar exists in MySQL. If it exists, where is it?
