[Zope] ZSQLmethods don't return a list?!

[alex@quad.com.ar]

hey guys

I created a ZSQL Method "SELECT * FROM users" which returns 10 rows
now in a python script:
type = context.type
sql = context.mySqlMethod()
return type(sql)

this returns: <type 'instance'>
while I expected <type 'list'>

the problem is, I wanted to do something like
return sql[2:4]

but I get an error:

Error Type: TypeError
Error Value: sequence index must be integer

Traceback (innermost last):

Shouldn't ZSQL methods return a list of dictionaries or anything similar to
it ??
any suggestions ?
