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 Nebula Graph 2.0.1, the SHOW TAG/EDGE INDEXES statement only returns Names.
