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
+---------+-----+

为了便于理解，进一步扩展示例（也将 key_send 设置为 true），展示截断的工作原理。

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
