AQL 无法通过 PK 找到行。选择时有行

Question

我在 aerospike 中有一个命名空间和一个集合，里面有信息。执行 SELECT * FROM mytecache.search_results 后，我得到大约 600 行：

"bdee9a37e3217f28a057b5e0ebbef43f_Sabre_13"    | "a:11:{s:5:"price";a:14:{s:5:"total";d:2947.5999999999999;s:11:"pricePerPax";d:1473.8;s:8:"totalflt";d:2947.5999999999999;s:9:"baseprice";d:1901.0799999999999;s:3:"tax";d:986.51999999999998;s:10:"servicefee";i:60;s:11:"markupprice";d:1961.0799999999999;s | "flight_bdee9a37e3217f28a057b5e0ebbef43f" | 147380   | LIST('["LH", "LH", "LH", "LH"]'....

如您所知，第一列是主键，所以我尝试 select 行（刚刚出现在 SELECT 中）：

aql> SELECT * FROM mytecache.search_results WHERE PK = "bdee9a37e3217f28a057b5e0ebbef43f_Sabre_13"

我得到：

Error: (2) AEROSPIKE_ERR_RECORD_NOT_FOUND

解释returns这个：

aql> EXPLAIN SELECT * FROM mytecache.search_results WHERE PK="bdee9a37e3217f28a057b5e0ebbef43f_Sabre_13"

这似乎是错误的。为什么查询没有返回结果，明明有结果？

Answer 1

"As you know, the first column is the primary key," -- 没有第一列是您的第一个 bin。主键是您用来编写记录的任何内容。 Aerospike 不存储您的主键。

您很可能对第一个 bin 为 "bdee9a37e3217f28a057b5e0ebbef43f_Sabre_13"

的记录使用了错误的 PK

https://www.aerospike.com/docs/tools/aql/data_management.html

“STATUS”是操作的状态。它将是客户返回的记录代码。例如：0 是 AEROSPIKE_OK，2 是 AEROSPIKE_ERR_RECORD_NOT_FOUND。

因此，即使您在 AQL 中执行解释，也会在 STATUS 中告诉您未找到该记录。

AQL 无法通过 PK 找到行。选择时有行

AQL can not find row by PK. Row is there when selecting
