[Zope] No Database-connection with Z SQL Methode

[Alexander Spanke]

Hello,

i use zope2.0b3 with MySQL as Database. The ZMySQLDatabase-Adabter works
fine. Now i want
include a SQL-Query with Z SQL-Methode. But if i do this, Z SQL-Methode
give the error-msg :
" no database connection found. please connect ... "

Is this a problem of the beta3, how can i debug the problem ?
