dBackend defines getDictCursorClass wich must return the class of the
cursor, not an instance, on mysql for instance we can just return
MySQLdb.cursors.DictCursor as it can be instanced passing a connection
object as argument.
Dabo assumes it can do this:
cur = CursorClass(connection)
On pymssql it cannot, the pymssqlCnx is not the connection itself,
pymssqlCnx._cnx is!, thats why i have defined getDictCursorClass as:
def getDictCursorClass(self):
import pymssql
class conCursor(pymssql.pymssqlCursor):
def __init__(self, src):
self.super(src._cnx)
def _getconn(self):
return self.__source
# pymssql doesn't supply this optional dbapi attribute, so
create it here.
connection = property(_getconn, None, None)
return conCursor
