SHOW TABLES
Introduced or updated: v1.2.415
Lists the tables in the current or a specified database.
note
Starting from version 1.2.415, the SHOW TABLES command no longer includes views in its results. To display views, use SHOW VIEWS instead.
Syntax
SHOW [ FULL ] TABLES
[ {FROM | IN} <database_name> ]
[ HISTORY ]
[ LIKE '<pattern>' | WHERE <expr> ]
| Parameter | Description |
|---|---|
| FULL | Lists the results with additional information. See Examples for more details. |
| FROM / IN | Specifies a database. If omitted, the command returns the results from the current database. |
| HISTORY | Displays the timestamps of table deletions within the retention period (24 hours by default). If a table has not been deleted yet, the value for drop_time is NULL. |
| LIKE | Filters the results by their names using case-sensitive pattern matching. |
| WHERE | Filters the results using an expression in the WHERE clause. |
Examples
The following example lists the names of all tables in the current database (default):
SHOW TABLES;
┌───────────────────┐
│ Tables_in_default │
├───────────────────┤
│ books │
│ mytable │
│ ontime │
│ products │
└───────────────────┘
The following example lists all the tables with additional information:
SHOW FULL TABLES;
┌──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────┐
│ tables │ table_type │ database │ catalog │ owner │ engine │ cluster_by │ create_time │ num_rows │ data_size │ data_compressed_size │ index_size │
├──────────┼────────────┼──────────┼─────────┼──────────────────┼────────┼────────────┼────────────────────────────┼──────────────────┼──────────────────┼──────────────────────┼──────────────────┤
│ books │ BASE TABLE │ default │ default │ account_admin │ FUSE │ │ 2024-01-16 03:53:15.354132 │ 0 │ 0 │ 0 │ 0 │
│ mytable │ BASE TABLE │ default │ default │ account_admin │ FUSE │ │ 2024-01-16 03:53:27.968505 │ 0 │ 0 │ 0 │ 0 │
│ ontime │ BASE TABLE │ default │ default │ account_admin │ FUSE │ │ 2024-01-16 03:53:42.052399 │ 0 │ 0 │ 0 │ 0 │
│ products │ BASE TABLE │ default │ default │ account_admin │ FUSE │ │ 2024-01-16 03:54:00.883985 │ 0 │ 0 │ 0 │ 0 │
└──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────┘
The following example demonstrates that the results will include dropped tables when the optional parameter HISTORY is present:
DROP TABLE products;
SHOW TABLES;
┌───────────────────┐
│ Tables_in_default │
├───────────────────┤
│ books │
│ mytable │
│ ontime │
└───────────────────┘
SHOW TABLES HISTORY;
┌────────────────────────────────────────────────┐
│ Tables_in_default │ drop_time │
├───────────────────┼────────────────────────────┤
│ books │ NULL │
│ mytable │ NULL │
│ ontime │ NULL │
│ products │ 2024-01-16 03:55:47.900362 │
└────────────────────────────────────────────────┘
The following example lists the tables containing the string "time" at the end of their name:
SHOW TABLES LIKE '%time';
┌───────────────────┐
│ Tables_in_default │
├───────────────────┤
│ ontime │
└───────────────────┘
-- CASE-SENSITIVE pattern matching.
-- No results will be returned if you code the previous statement like this:
SHOW TABLES LIKE '%TIME';
The following example lists tables where the data size is greater than 1,000 bytes:
SHOW TABLES WHERE data_size > 1000 ;
┌───────────────────┐
│ Tables_in_default │
├───────────────────┤
│ ontime │
└───────────────────┘
