[Zope] ZSQL Catch Errors

I'm using ZODBCA for my Access Database. I need to catch the 'sql.error' exceptions returned by errors on this connection. Now I get a page like this: ---------- Site Error An error was encountered while publishing this resource. Error Type: sql.error Error Value: ('37000', -3502, '[Microsoft][Controlador ODBC Microsoft Access] Error de sintaxis en la instrucci\xf3n INSERT INTO.') ---------- I need to know how to catch that error value from my python script (the one which calls the zsql method), something like: ---- try: salida=context.qReceptores(tabla='miTabla',columnas=columnas,valores=valores ) except: WHAT CAN I DO TO GET THE VALUES OF THE ERROR?? ---- Thanks in advance!
