这是我的问题:
currentID = 7
deck = range(0,3)
similarIDs = db.GqlQuery('SELECT * FROM itemSet WHERE jokeID=:1 AND position IN :2', currentID, deck[:3]).fetch(100)
这是我的模特:
class itemSet(db.Model):
jokeID = db.IntegerProperty()
jokeID2 = db.IntegerProperty()
position = db.IntegerProperty()
当我在GoogleAppEngine数据查看器中执行查询时,我得到了结果:
我错过了什么?
答案 0 :(得分:1)
以下带有GqlQuery语句的代码适用于我。
item = itemSet()
item.jokeID = 7
item.jokeID2 = 1
item.position = 0
item.put()
item = itemSet()
item.jokeID = 7
item.jokeID2 = 2
item.position = 1
item.put()
currentID = 7
deck = range(0,3)
similarIDs = db.GqlQuery('SELECT * FROM itemSet \
WHERE jokeID=:1 AND position IN :2'
, currentID, deck[:3]).fetch(100)
for item in similarIDs:
logging.info("%s : %s" % (item.jokeID, item.position))
它返回:
