The SQL method returns a list of brains. The DTML Method returns a
string (by default). I would suggest using a python script to return a
list of strings from the sql method like so:

list = []
for row in context.sqlMethod(context.REQUEST):
    list.append(row.field)
return list

However, a lines property does not take a list as input, it takes
newline delimited string, so the following python script might work
better (untested):

import string
list = []
for row in context.sqlMethod(context.REQUEST):
    list.append(row.field)
return string.join(list, '\n')
