# SHOW Statements {#show-queries}

## SHOW CREATE TABLE {#show-create-table}

``` sql
SHOW CREATE [TEMPORARY] [TABLE|DICTIONARY] [db.]table [INTO OUTFILE filename] [FORMAT format]
```

Returns a single `String`-type ‘statement’ column, which contains a single value – the `CREATE` query used for creating the specified object.

## SHOW DATABASES {#show-databases}

Prints a list of all databases.

```sql
SHOW DATABASES [LIKE | ILIKE | NOT LIKE '<pattern>'] [LIMIT <N>] [INTO OUTFILE filename] [FORMAT format]
```

This statement is identical to the query:

```sql
SELECT name FROM system.databases [WHERE name LIKE | ILIKE | NOT LIKE '<pattern>'] [LIMIT <N>] [INTO OUTFILE filename] [FORMAT format]
```

### Examples {#examples}

Getting database names, containing the symbols sequence 'de' in their names:

``` sql
SHOW DATABASES LIKE '%de%'
```

Result:

``` text
┌─name────┐
│ default │
└─────────┘
```

Getting database names, containing symbols sequence 'de' in their names, in the case insensitive manner:

``` sql
SHOW DATABASES ILIKE '%DE%'
```

Result:

``` text
┌─name────┐
│ default │
└─────────┘
```

Getting database names, not containing the symbols sequence 'de' in their names:

``` sql
SHOW DATABASES NOT LIKE '%de%'
```

Result:

``` text
┌─name───────────────────────────┐
│ _temporary_and_external_tables │
│ system                         │
│ test                           │
│ tutorial                       │
└────────────────────────────────┘
```

Getting the first two rows from database names:

``` sql
SHOW DATABASES LIMIT 2
```

Result:

``` text
┌─name───────────────────────────┐
│ _temporary_and_external_tables │
│ default                        │
└────────────────────────────────┘
```

## SHOW PROCESSLIST {#show-processlist}

``` sql
SHOW PROCESSLIST [INTO OUTFILE filename] [FORMAT format]
```

Outputs the content of the [system.processes](../../operations/system-tables/processes.md#system_tables-processes) table, that contains a list of queries that is being processed at the moment, excepting `SHOW PROCESSLIST` queries.

The `SELECT * FROM system.processes` query returns data about all the current queries.

Tip (execute in the console):

``` bash
$ watch -n1 "clickhouse-client --query='SHOW PROCESSLIST'"
```

## SHOW TABLES {#show-tables}

Displays a list of tables.

```sql
SHOW [TEMPORARY] TABLES [{FROM | IN} <db>] [LIKE | ILIKE | NOT LIKE '<pattern>'] [LIMIT <N>] [INTO OUTFILE <filename>] [FORMAT <format>]
```

If the `FROM` clause is not specified, the query returns the list of tables from the current database.

This statement is identical to the query:

```sql
SELECT name FROM system.tables [WHERE name LIKE | ILIKE | NOT LIKE '<pattern>'] [LIMIT <N>] [INTO OUTFILE <filename>] [FORMAT <format>]
```

### Examples {#examples}

Getting table names, containing the symbols sequence 'user' in their names:

``` sql
SHOW TABLES FROM system LIKE '%user%'
```

Result:

``` text
┌─name─────────────┐
│ user_directories │
│ users            │
└──────────────────┘
```

Getting table names, containing sequence 'user' in their names, in the case insensitive manner:

``` sql
SHOW TABLES FROM system ILIKE '%USER%'
```

Result:

``` text
┌─name─────────────┐
│ user_directories │
│ users            │
└──────────────────┘
```

Getting table names, not containing the symbol sequence 's' in their names:

``` sql
SHOW TABLES FROM system NOT LIKE '%s%'
```

Result:

``` text
┌─name─────────┐
│ metric_log   │
│ metric_log_0 │
│ metric_log_1 │
└──────────────┘
```

Getting the first two rows from table names:

``` sql
SHOW TABLES FROM system LIMIT 2
```

Result:

``` text
┌─name───────────────────────────┐
│ aggregate_function_combinators │
│ asynchronous_metric_log        │
└────────────────────────────────┘
```

## SHOW DICTIONARIES {#show-dictionaries}

Displays a list of [external dictionaries](../../sql-reference/dictionaries/external-dictionaries/external-dicts.md).

``` sql
SHOW DICTIONARIES [FROM <db>] [LIKE '<pattern>'] [LIMIT <N>] [INTO OUTFILE <filename>] [FORMAT <format>]
```

If the `FROM` clause is not specified, the query returns the list of dictionaries from the current database.

You can get the same results as the `SHOW DICTIONARIES` query in the following way:

``` sql
SELECT name FROM system.dictionaries WHERE database = <db> [AND name LIKE <pattern>] [LIMIT <N>] [INTO OUTFILE <filename>] [FORMAT <format>]
```

**Example**

The following query selects the first two rows from the list of tables in the `system` database, whose names contain `reg`.

``` sql
SHOW DICTIONARIES FROM db LIKE '%reg%' LIMIT 2
```

``` text
┌─name─────────┐
│ regions      │
│ region_names │
└──────────────┘
```
