SHOW CREATE INDEX¶
SHOW CREATE INDEX展示创建 Tag 或者 Edge type 时使用的 nGQL 语句，其中包含索引的详细信息，例如其关联的属性。
语法¶
ngql
SHOW CREATE {TAG | EDGE} INDEX <index_name>;
示例¶
用户可以先运行SHOW TAG INDEXES查看有哪些 Tag 索引，然后用SHOW CREATE TAG INDEX查看指定索引的创建信息。
```ngql nebula> SHOW TAG INDEXES; +------------------+----------+----------+ | Index Name | By Tag | Columns | +------------------+----------+----------+ | "player_index_0" | "player" | [] | | "player_index_1" | "player" | ["name"] | +------------------+----------+----------+
nebula> SHOW CREATE TAG INDEX player_index_1;
+------------------+--------------------------------------------------+
| Tag Index Name | Create Tag Index |
+------------------+--------------------------------------------------+
| "player_index_1" | "CREATE TAG INDEX player_index_1 ON player ( |
| | name(20) |
| | )" |
+------------------+--------------------------------------------------+
```
Edge type 索引可以用类似的方法查询：
```ngql nebula> SHOW EDGE INDEXES; +----------------+----------+---------+ | Index Name | By Edge | Columns | +----------------+----------+---------+ | "follow_index" | "follow" | [] | +----------------+----------+---------+
nebula> SHOW CREATE EDGE INDEX follow_index;
+-----------------+-------------------------------------------------+
| Edge Index Name | Create Edge Index |
+-----------------+-------------------------------------------------+
| "follow_index" | "CREATE EDGE INDEX follow_index ON follow ( |
| | )" |
+-----------------+-------------------------------------------------+
```
