获得总场比赛我有以下Postgres的查询： SELECT p_id as player_id, name as player_name
FROM Players
LEFT OUTER JOIN matches
ON Players.p_id = matches.player1 or Players.p_id = matches.player2
;
，并返回以下 player_id |
class TradeItem(models.Model):
...
class Wishlist(models.Model):
user = models.ForeignKey(User, related_name='wishlist_user')
item = models.ForeignKey(TradeItem, related_name='wishlis
var response = client.Search<Timeline>(
x => x.Query(
q => q.Bool(
b => b.Must(queryContainer)))
.Size(0)
.Aggregations(a => a
.DateRange("last_24_hours",
我有一个模型，看起来像这样： class Company(models.Model):
id = models.CharField(max_length=20)
name = models.CharField(max_length=60)
class Department(models.Model):
id = models.CharField(max_lengt
我有这样的查询： var result = clientConnection.Search<dynamic>(s => s
.Index(indexname)
.Type(typename)
.Aggregations(a => a
.DateRange(fieldvalue, d => d
.Field(fieldname)
.Range
让我们想象一下观点： ，我想改变它优雅的方式，为类似如下： 我请使用以下查询： SELECT empid,
sum(CASE WHEN YEAR(ordermonth) = '2014' THEN val END) '2014',
sum(CASE WHEN YEAR(ordermonth) = '2015' THEN val END) '2015',
sum(CAS
