* Restructure query-languages docs files for clarity (#124797) In a few previous PR's we restructured the ES|QL docs to make it possible to generate them dynamically. This PR just moves a few files around to make the query languages docs easier to work with, and a little more organized like the ES|QL docs. A bit part of this was setting up redirects to the new locations, so other repo's could correctly link to the elasticsearch docs. * After running tests, we revert a few features * Fix build.gradle and improved some generating code * After running tests * Update x-pack/plugin/esql/build.gradle

# SHOW TABLES [sql-syntax-show-tables]
|
|
|
|
```sql
|
|
SHOW TABLES
|
|
[CATALOG [catalog_identifier | <1>
|
|
LIKE pattern]]? <2>
|
|
[INCLUDE FROZEN]? <3>
|
|
[table_identifier | <4>
|
|
LIKE pattern]? <5>
|
|
```
|
|
|
|
1. Catalog (cluster) identifier. Supports wildcards (`*`).
|
|
2. SQL LIKE pattern matching catalog names.
|
|
3. Whether or not to include frozen indices.
|
|
4. Single table (index or data stream) identifier or double-quoted multi-target pattern.
|
|
5. SQL LIKE pattern matching table names.
|
|
|
|
|
|
See [index patterns](/reference/query-languages/sql/sql-index-patterns.md) for more information about patterns.
|
|
|
|
**Description**: List the tables available to the current user and their type.
|
|
|
|
```sql
|
|
SHOW TABLES;
|
|
|
|
catalog | name | type | kind
|
|
---------------+---------------+----------+---------------
|
|
javaRestTest |emp |TABLE |INDEX
|
|
javaRestTest |employees |VIEW |ALIAS
|
|
javaRestTest |library |TABLE |INDEX
|
|
```
|
|
|
|
Match multiple indices by using {{es}} [multi-target syntax](/reference/elasticsearch/rest-apis/api-conventions.md#api-multi-index) notation:
|
|
|
|
```sql
|
|
SHOW TABLES "*,-l*";
|
|
|
|
catalog | name | type | kind
|
|
---------------+---------------+----------+---------------
|
|
javaRestTest |emp |TABLE |INDEX
|
|
javaRestTest |employees |VIEW |ALIAS
|
|
```
|
|
|
|
One can also use the `LIKE` clause to restrict the list of names to the given pattern.
|
|
|
|
The pattern can be an exact match:
|
|
|
|
```sql
|
|
SHOW TABLES LIKE 'emp';
|
|
|
|
catalog | name | type | kind
|
|
---------------+---------------+----------+---------------
|
|
javaRestTest |emp |TABLE |INDEX
|
|
```
|
|
|
|
Multiple chars:
|
|
|
|
```sql
|
|
SHOW TABLES LIKE 'emp%';
|
|
|
|
catalog | name | type | kind
|
|
---------------+---------------+----------+---------------
|
|
javaRestTest |emp |TABLE |INDEX
|
|
javaRestTest |employees |VIEW |ALIAS
|
|
```
|
|
|
|
A single char:
|
|
|
|
```sql
|
|
SHOW TABLES LIKE 'em_';
|
|
|
|
catalog | name | type | kind
|
|
---------------+---------------+----------+---------------
|
|
javaRestTest |emp |TABLE |INDEX
|
|
```
|
|
|
|
Or a mixture of single and multiple chars:
|
|
|
|
```sql
|
|
SHOW TABLES LIKE '%em_';
|
|
|
|
catalog | name | type | kind
|
|
---------------+---------------+----------+---------------
|
|
javaRestTest |emp |TABLE |INDEX
|
|
```
|
|
|
|
List tables within remote clusters whose names are matched by a wildcard:
|
|
|
|
```sql
|
|
SHOW TABLES CATALOG 'my_*' LIKE 'test_emp%';
|
|
|
|
catalog | name | type | kind
|
|
-----------------+---------------+---------------+---------------
|
|
my_remote_cluster|test_emp |TABLE |INDEX
|
|
my_remote_cluster|test_emp_copy |TABLE |INDEX
|
|
```
|
