SHOW CREATE INDEX

SHOW CREATE INDEX shows the statement used when creating a tag or an edge type. It contains detailed information about the index, such as its associated properties.

Syntax

SHOW CREATE {TAG | EDGE} INDEX <index_name>;

Examples

You can run SHOW TAG INDEXES to list all tag indexes, and then use SHOW CREATE TAG INDEX to show the information about the creation of the specified index.

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 indexes can be queried through a similar approach.

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` ( |
|                 | )"                                              |
+-----------------+-------------------------------------------------+

Legacy version compatibility

In NebulaGraph 2.0.1, the SHOW TAG/EDGE INDEXES statement only returns Names.
