我正在尝试从aeropike数据存储集中删除记录。我正在使用here给出的查询语言。

但看起来查询有语法错误。我在下面给出了查询和相应的错误。

知道我的查询中有什么问题。提前谢谢。

Answer 1

aql> insert into ns1.user (pk, name, age) values (1, 'Raj', 24)
OK, 1 record affected.

aql> insert into ns1.user (pk, name, age) values (2, 'Kumar', 24)
OK, 1 record affected.

aql> select * from ns1.user
+---------+-----+
| name    | age |
+---------+-----+
| "Raj"   | 24  |
| "Kumar" | 24  |
+---------+-----+
2 rows in set (0.039 secs)

OK

aql> delete from ns1.user where pk = 1
OK, 1 record affected.

aql> select * from ns1.user
+---------+-----+
| name    | age |
+---------+-----+
| "Kumar" | 24  |
+---------+-----+
1 row in set (0.038 secs)

OK

进一步扩展示例（也显示key_send设置为true）以便于理解，显示truncate如何工作。

aql> set key_send true
KEY_SEND = true
aql> insert into ns1.user (pk, name, age) values (1, 'Raj', 24)
OK, 1 record affected.

aql> insert into ns1.user (pk, name, age) values (2, 'Kumar', 25)
OK, 1 record affected.

aql> select * from ns1.user
+----+---------+-----+
| PK | name    | age |
+----+---------+-----+
| 1  | "Raj"   | 24  |
| 2  | "Kumar" | 25  |
+----+---------+-----+
2 rows in set (0.037 secs)

OK

aql> truncate ns1.user
OK

aql> select * from ns1.user
0 rows in set (0.036 secs)

OK

Aerospike aql令牌附近的语法错误 - 确保字符串值用引号括起来
