You know the custom classes you can use in the ZSQL Advanced tab?
You can use ZClasses to implement such classes.

The method "Shared.DC.ZRDB.DA.DA.manage_product_zclass_info"
runs through all ZClasses and tries to build a list of
ZClasses that can be used for this purpose.

Thereby, it hits a ZClass that is dependent on a product that is no longer
installed.

Your options:

  *  find the ZClass that produces the problem and delete it.

     It is probably an old Portal Toolkit ZClass.

  *  add a "try ... except" round line 476 of "Shared/DC/ZRDB/DA.py"

     File a bug report to "<http://collector.zope.org>" with your
     patch
