# SHOW Statements

SHOW statements are used to list objects within their corresponding parent, such as catalogs, databases, tables and views, columns, functions, and modules. See the individual commands for more details and additional options.

SHOW CREATE statements are used to print a DDL statement with which a given object can be created. The currently 'SHOW CREATE' statement is only available in printing DDL statement of the given table and view.

Flink SQL supports the following SHOW statements for now:
- SHOW CATALOGS
- SHOW CURRENT CATALOG
- SHOW CREATE CATALOG
- SHOW DATABASES
- SHOW CURRENT DATABASE
- SHOW TABLES
- SHOW CREATE TABLE
- SHOW COLUMNS
- SHOW PARTITIONS
- SHOW PROCEDURES
- SHOW VIEWS
- SHOW CREATE VIEW
- SHOW FUNCTIONS
- SHOW MODULES
- SHOW JARS
- SHOW JOBS

## Run a SHOW statement

{{< tabs "show" >}}
{{< tab "Java" >}}

SHOW statements can be executed with the `executeSql()` method of the `TableEnvironment`. The `executeSql()` method returns objects for a successful SHOW operation, otherwise will throw an exception.

The following examples show how to run a SHOW statement in `TableEnvironment`.

{{< /tab >}}
{{< tab "Scala" >}}

SHOW statements can be executed with the `executeSql()` method of the `TableEnvironment`. The `executeSql()` method returns objects for a successful SHOW operation, otherwise will throw an exception.

The following examples show how to run a SHOW statement in `TableEnvironment`.

{{< /tab >}}
{{< tab "Python" >}}

SHOW statements can be executed with the `execute_sql()` method of the `TableEnvironment`. The `execute_sql()` method returns objects for a successful SHOW operation, otherwise will throw an exception.

The following examples show how to run a SHOW statement in `TableEnvironment`.

{{< /tab >}}
{{< tab "SQL CLI" >}}

SHOW statements can be executed in [SQL CLI]({{< ref "docs/dev/table/sqlClient" >}}).

The following examples show how to run a SHOW statement in SQL CLI.

## SHOW CATALOGS

```sql
SHOW CATALOGS [ [NOT] (LIKE | ILIKE) <sql_like_pattern> ]
```

Show all catalogs. Additionally, the output of this statement may be filtered by an optional matching pattern.

**LIKE**
Show all catalogs with a `LIKE` clause, whose name is similar to the `<sql_like_pattern>`.

The syntax of the SQL pattern in the `LIKE` clause is the same as that of the `MySQL` dialect.
* `%` matches any number of characters, even zero characters, and `\%` matches one `%` character.
* `_` matches exactly one character, `\_` matches one `_` character.

**ILIKE**
The same behavior as `LIKE` but the SQL pattern is case-insensitive.

### SHOW CATALOGS EXAMPLES

Assumes that we have `catalog1` and `catalog2` in the session.

- Show all catalogs.

```sql
show catalogs;
+-----------------+
|    catalog name |
+-----------------+
|        catalog1 |
|        catalog2 |
| default_catalog |
+-----------------+
3 rows in set
```

- Show all catalogs, which are similar to the given SQL pattern.

```sql
show catalogs like '%log1';
-- show catalogs ilike '%log1';
-- show catalogs ilike '%LOG1';
+--------------+
| catalog name |
+--------------+
|     catalog1 |
+--------------+
1 row in set
```

## SHOW CURRENT CATALOG

```sql
SHOW CURRENT CATALOG
```

Show current catalog.

## SHOW CREATE CATALOG

```sql
SHOW CREATE CATALOG catalog_name
```

Show creation statement for an existing catalog.

The output includes the catalog's name and relevant properties, which allows you to gain an intuitive understanding of the underlying catalog's metadata.

Assumes that the catalog `cat2` is created as follows:
```sql
create catalog cat2 WITH (
    'type'='generic_in_memory',
    'default-database'='db'
);
```
Shows the creation statement.
```sql
show create catalog cat2;
+---------------------------------------------------------------------------------------------+
|                                                                                      result |
+---------------------------------------------------------------------------------------------+
| CREATE CATALOG `cat2` WITH (
  'default-database' = 'db',
  'type' = 'generic_in_memory'
)
 |
+---------------------------------------------------------------------------------------------+
1 row in set
```

## SHOW DATABASES

```sql
SHOW DATABASES [ ( FROM | IN ) catalog_name] [ [NOT] (LIKE | ILIKE) <sql_like_pattern> ]
```

Show all databases within optionally specified catalog. 
If no catalog is specified, then the default catalog is used. 
Additionally, a `<sql_like_pattern>` can be used to filter the databases.

**LIKE**
Show all databases with a `LIKE` clause, whose name is similar to the `<sql_like_pattern>`.

The syntax of the SQL pattern in the `LIKE` clause is the same as that of the `MySQL` dialect.
* `%` matches any number of characters, even zero characters, and `\%` matches one `%` character.
* `_` matches exactly one character, `\_` matches one `_` character.

**ILIKE**
The same behavior as `LIKE` but the SQL pattern is case-insensitive.

## SHOW CURRENT DATABASE

```sql
SHOW CURRENT DATABASE
```

Show current database.

## SHOW TABLES

```sql
SHOW TABLES [ ( FROM | IN ) [catalog_name.]database_name ] [ [NOT] LIKE <sql_like_pattern> ]
```

Show all tables for an optionally specified database. If no database is specified then the tables are returned from the current database. Additionally, the output of this statement may be filtered by an optional matching pattern.

**LIKE**
Show all tables with given table name and optional `LIKE` clause, whose name is whether similar to the `<sql_like_pattern>`.

The syntax of sql pattern in `LIKE` clause is the same as that of `MySQL` dialect.
* `%` matches any number of characters, even zero characters, `\%` matches one `%` character.
* `_` matches exactly one character, `\_` matches one `_` character.

### SHOW TABLES EXAMPLES

Assumes that the `db1` database located in `catalog1` catalog has the following tables:
* person
* dim

the current database in session has the following tables:
* items
* orders

- Shows all tables of the given database.

```sql
show tables from db1;
-- show tables from catalog1.db1;
-- show tables in db1;
-- show tables in catalog1.db1;
+------------+
| table name |
+------------+
|        dim |
|     person |
+------------+
2 rows in set
```

- Shows all tables of the given database, which are similar to the given sql pattern.

```sql
show tables from db1 like '%n';
-- show tables from catalog1.db1 like '%n';
-- show tables in db1 like '%n';
-- show tables in catalog1.db1 like '%n';
+------------+
| table name |
+------------+
|     person |
+------------+
1 row in set
```

- Shows all tables of the given database, which are not similar to the given sql pattern.

```sql
show tables from db1 not like '%n';
-- show tables from catalog1.db1 not like '%n';
-- show tables in db1 not like '%n';
-- show tables in catalog1.db1 not like '%n';
+------------+
| table name |
+------------+
|        dim |
+------------+
1 row in set
```

- Shows all tables of the current database.

```sql
show tables;
+------------+
| table name |
+------------+
|      items |
|     orders |
+------------+
2 rows in set
```


## SHOW CREATE TABLE

```sql
SHOW CREATE TABLE [[catalog_name.]db_name.]table_name
```

Show create table statement for specified table.

The output includes the table name, column names, data types, constraints, comments, and configurations.

It is a very useful statement when you need to understand the structure, configuration and constraints of an existing table or to recreate the table in another database.

Assumes that the table `orders` is created as follows:
```sql
CREATE TABLE orders (
  order_id BIGINT NOT NULL comment 'this is the primary key, named ''order_id''.',
  product VARCHAR(32),
  amount INT,
  ts TIMESTAMP(3) comment 'notice: watermark, named ''ts''.',
  ptime AS PROCTIME() comment 'notice: computed column, named ''ptime''.',
  WATERMARK FOR ts AS ts - INTERVAL '1' SECOND,
  CONSTRAINT `PK_order_id` PRIMARY KEY (order_id) NOT ENFORCED
) WITH (
  'connector' = 'datagen'
);
```
Shows the creation statement.
```sql
show create table orders;
+---------------------------------------------------------------------------------------------+
|                                                                                      result |
+---------------------------------------------------------------------------------------------+
| CREATE TABLE `default_catalog`.`default_database`.`orders` (
  `order_id` BIGINT NOT NULL COMMENT 'this is the primary key, named ''order_id''.',
  `product` VARCHAR(32),
  `amount` INT,
  `ts` TIMESTAMP(3) COMMENT 'notice: watermark, named ''ts''.',
  `ptime` AS PROCTIME() COMMENT 'notice: computed column, named ''ptime''.',
  WATERMARK FOR `ts` AS `ts` - INTERVAL '1' SECOND,
  CONSTRAINT `PK_order_id` PRIMARY KEY (`order_id`) NOT ENFORCED
) WITH (
  'connector' = 'datagen'
)
 |
+---------------------------------------------------------------------------------------------+
1 row in set
```

<span class="label label-danger">Attention</span> Currently `SHOW CREATE TABLE` only supports table that is created by Flink SQL DDL.

## SHOW COLUMNS

```sql
SHOW COLUMNS ( FROM | IN ) [[catalog_name.]database.]<table_name> [ [NOT] LIKE <sql_like_pattern>]
```

Show all columns of the table with given table name and optional like clause.

**LIKE**
Show all columns of the table with given table name and optional `LIKE` clause, whose name is whether similar to the `<sql_like_pattern>`.

The syntax of sql pattern in `LIKE` clause is the same as that of `MySQL` dialect.

### SHOW COLUMNS EXAMPLES

Assumes that the table named `orders` in the `database1` database which is located in the `catalog1` catalog has the following structure:

```sql
+---------+-----------------------------+-------+-----------+---------------+----------------------------+
|    name |                        type |  null |       key |        extras |                  watermark |
+---------+-----------------------------+-------+-----------+---------------+----------------------------+
|    user |                      BIGINT | false | PRI(user) |               |                            |
| product |                 VARCHAR(32) |  true |           |               |                            |
|  amount |                         INT |  true |           |               |                            |
|      ts |      TIMESTAMP(3) *ROWTIME* |  true |           |               | `ts` - INTERVAL '1' SECOND |
|   ptime | TIMESTAMP_LTZ(3) *PROCTIME* | false |           | AS PROCTIME() |                            |
+---------+-----------------------------+-------+-----------+---------------+----------------------------+
```

- Shows all columns of the given table.

```sql
show columns from orders;
-- show columns from database1.orders;
-- show columns from catalog1.database1.orders;
-- show columns in orders;
-- show columns in database1.orders;
-- show columns in catalog1.database1.orders;
+---------+-----------------------------+-------+-----------+---------------+----------------------------+

## SHOW PARTITIONS

```sql
SHOW PARTITIONS [[catalog_name.]database.]<table_name> [ PARTITION <partition_spec>]

<partition_spec>:
  (key1=val1, key2=val2, ...)
```

Show all partitions of the partitioned table with the given table name and optional partition clause.

**PARTITION**
Show all the partitions which are under the provided <partition_spec> in the given table.

### SHOW PARTITIONS EXAMPLES

Assumes that the partitioned table `table1` in the `database1` database which is located in the `catalog1` catalog has the following partitions:

```sql
+---------+-----------------------------+
|      id |                        date |
+---------+-----------------------------+
|    1001 |                  2020-01-01 |
|    1002 |                  2020-01-01 |
|    1002 |                  2020-01-02 |
+---------+-----------------------------+
```

- Shows all partitions of the given table.

```sql
show partitions table1;
-- show partitions database1.table1;
-- show partitions catalog1.database1.table1;
+---------+-----------------------------+
|      id |                        date |
+---------+-----------------------------+
|    1001 |                  2020-01-01 |
|    1002 |                  2020-01-01 |
|    1002 |                  2020-01-02 |
+---------+-----------------------------+
3 rows in set
```

- Shows all partitions of the given table with the given partition spec.

```sql
show partitions table1 partition (id=1002);
-- show partitions database1.table1 partition (id=1002);
-- show partitions catalog1.database1.table1 partition (id=1002);
+---------+-----------------------------+
|      id |                        date |
+---------+-----------------------------+
|    1002 |                  2020-01-01 |
|    1002 |                  2020-01-02 |
+---------+-----------------------------+
2 rows in set
```

## SHOW PROCEDURES

```sql
SHOW PROCEDURES [ ( FROM | IN ) [catalog_name.]database_name ] [ [NOT] (LIKE | ILIKE) <sql_like_pattern> ]	
```

Show all procedures for an optionally specified database. If no database is specified then the procedures are returned from the current database. Additionally, a `<sql_like_pattern>` can be used to filter the procedures.

**LIKE**
Show all procedures with a `LIKE` clause, whose name is similar to the `<sql_like_pattern>`.

The syntax of the SQL pattern in the `LIKE` clause is the same as that of the `MySQL` dialect.
* `%` matches any number of characters, even zero characters, and `\%` matches one `%` character.
* `_` matches exactly one character, `\_` matches one `_` character.

**ILIKE**
The same behavior as `LIKE` but the SQL pattern is case-insensitive.

## SHOW VIEWS

```sql
SHOW VIEWS [ ( FROM | IN ) [catalog_name.]database_name ] [ [NOT] LIKE <sql_like_pattern> ]
```

Show all views for an optionally specified database. If no database is specified then the views are returned from the current database. Additionally, the output of this statement may be filtered by an optional matching pattern.

**LIKE**
Show all views with given view name and optional `LIKE` clause, whose name is whether similar to the `<sql_like_pattern>`.

The syntax of sql pattern in `LIKE` clause is the same as that of `MySQL` dialect.
* `%` matches any number of characters, even zero characters, `\%` matches one `%` character.
* `_` matches exactly one character, `\_` matches one `_` character.

## SHOW CREATE VIEW

```sql
SHOW CREATE VIEW [catalog_name.][db_name.]view_name
```

Show create view statement for specified view.

## SHOW FUNCTIONS

```sql
SHOW [USER] FUNCTIONS [ ( FROM | IN ) [catalog_name.]database_name ] [ [NOT] (LIKE | ILIKE) <sql_like_pattern> ]	
```

Show all functions including system functions and user-defined functions for an optionally specified database. If no database is specified then the functions are returned from the current database. Additionally, a `<sql_like_pattern>` can be used to filter the functions.

**USER**
Show only user-defined functions for an optionally specified database. If no database is specified then the functions are returned from the current database. Additionally, a `<sql_like_pattern>` can be used to filter the functions.

**LIKE**
Show all functions with a `LIKE` clause, whose name is similar to the `<sql_like_pattern>`.

The syntax of the SQL pattern in the `LIKE` clause is the same as that of the `MySQL` dialect.
* `%` matches any number of characters, even zero characters, and `\%` matches one `%` character.
* `_` matches exactly one character, `\_` matches one `_` character.

**ILIKE**
The same behavior as `LIKE` but the SQL pattern is case-insensitive.

## SHOW MODULES

```sql
SHOW [FULL] MODULES
```

Show all enabled module names with resolution order.

**FULL**
Show all loaded modules and enabled status with resolution order.

## SHOW JARS

```sql
SHOW JARS
```

Show all added jars in the session classloader which are added by [`ADD JAR`]({{< ref "docs/dev/table/sql/jar" >}}#add-jar) statements.

<span class="label label-danger">Attention</span> Currently `SHOW JARS` statements only work in the [SQL CLI]({{< ref "docs/dev/table/sqlClient" >}}) or [SQL Gateway]({{< ref "docs/dev/table/sql-gateway/overview" >}}).

## SHOW JOBS

```sql
SHOW JOBS
```

Show the jobs in the Flink cluster.

<span class="label label-danger">Attention</span> Currently `SHOW JOBS` statements only work in the [SQL CLI]({{< ref "docs/dev/table/sqlClient" >}}) or [SQL Gateway]({{< ref "docs/dev/table/sql-gateway/overview" >}}).
