Couchbase 查询未按预期工作

Question

使用 Couchbase 4.1 我有以下文档结构

"bucketName": {
                "UserId": "user1",
                "skillSet": {
                    "punchPower": 1,
                    "kickPower": 1,
                    "specialPower": "Extreme programmer"
                },
                "id": "GameUser_XXX1D",
                "timestamp": 1464935606358
            }

我想要一个查询，它将 return 我返回最近的时间戳和所有匹配项的总数，这就是我所拥有的。

select count(timestamp) as users, timestamp from bucketName where id like 'GameUser__%' AND 
skillSet.specialPower = 'Extreme Programmer' AND 
skillSet.kickPower = 1 AND 
skillSet.punchPower = 1 AND 
timestamp BETWEEN $sometimeIPassHere AND $sometimeIPassHere 
ORDER BY timestamp desc limit 1;

这 returns 返回正确的用户数量，正如我预期的那样，但是正在 returned 的时间戳不正确最旧的时间戳正在 returned 就好像 desc 在我的查询中没有被考虑。我试过删除并应用 asc，这也 return 得到了相同的结果。

如何解决这个不正确的查询结果

Answer 1

我能够通过应用 max() 方法来实现它。

select max(timestamp), count(timestamp) as users, timestamp from bucketName where id like 'GameUser__%' AND 
skillSet.specialPower = 'Extreme Programmer' AND 
skillSet.kickPower = 1 AND 
skillSet.punchPower = 1 AND 
timestamp BETWEEN $sometimeIPassHere AND $sometimeIPassHere 
ORDER BY timestamp desc limit 1;
