[编辑](https://github.com/oceanbase/oceanbase-doc/edit/V4.6.0/zh-CN/700.reference/600.pl-reference/200.pl-mysql/1000.pl-system-package-mysql/17850.dbms-vector-mysql/600.flush-index-mysql.md)  

`FLUSH_INDEX` 过程用于手动强制触发转储任务，对应 HNSW 向量索引中**活跃增量段冻结并落盘**的流程。原理说明请参见 [向量索引原理](https://www.oceanbase.com/docs/common-oceanbase-database-cn-1000000005699342)。

## 语法

```sql
PROCEDURE FLUSH_INDEX(
    IN     TABLE_NAME             VARCHAR(65535),
    IN     IDX_NAME               VARCHAR(65535)
);

```

## 参数说明

| 参数 | 描述 |
| --- | --- |
| table_name | 表名。 |
| idx_name | 索引名。 |

## 示例

创建测试表。

```sql
CREATE TABLE vector_index_test(c1 INT, c2 VECTOR(3), PRIMARY KEY(c1), VECTOR INDEX idx1(c2) WITH (distance=l2, type=hnsw, lib=vsag));

```

写入测试数据。

```sql
INSERT INTO vector_index_test VALUES(1, '[0.203846,0.205289,0.880265]');
INSERT INTO vector_index_test VALUES(2, '[0.484526,0.669954,0.986755]');
INSERT INTO vector_index_test VALUES(3, '[0.327936,0.048756,0.084670]');
INSERT INTO vector_index_test VALUES(4, '[0.148869,0.878546,0.028024]');
INSERT INTO vector_index_test VALUES(5, '[0.334970,0.857377,0.886132]');
INSERT INTO vector_index_test VALUES(6, '[0.117582,0.302352,0.471198]');
INSERT INTO vector_index_test VALUES(7, '[0.551185,0.231134,0.075354]');
INSERT INTO vector_index_test VALUES(8, '[0.185221,0.315131,0.558301]');
INSERT INTO vector_index_test VALUES(9, '[0.928764,0.254038,0.272721]');

```

触发更新。

```sql
-- 触发转储任务。
CALL DBMS_VECTOR.FLUSH_INDEX('vector_index_test', 'idx1');

```
