SHOW USER FUNCTIONS¶

Lists all user-defined functions (UDFs) for which you have access privileges. Use this command to list the UDFs for a specified database or schema (or the current database/schema for the session), or across your entire account.

For a command that lists all functions, including built-in functions, see SHOW FUNCTIONS.

See also:: SHOW FUNCTIONS, SHOW EXTERNAL FUNCTIONS, FUNCTIONS view (Information Schema), FUNCTIONS view (Account Usage)

Syntax¶

SHOW USER FUNCTIONS [ LIKE '<pattern>' ]
  [ IN
    {
      ACCOUNT                                         |

      DATABASE                                        |
      DATABASE <database_name>                        |

      SCHEMA                                          |
      SCHEMA <schema_name>                            |
      <schema_name>

      APPLICATION <application_name>                  |
      APPLICATION PACKAGE <application_package_name>  |
    }
  ]

Parameters¶

LIKE 'pattern'

Optionally filters the command output by object name. The filter uses case-insensitive pattern matching, with support for SQL wildcard characters (% and _).

For example, the following patterns return the same results:

... LIKE '%testing%' ...

... LIKE '%TESTING%' ...

. Default: No value (no filtering is applied to the output).

[ IN ... ]

Optionally specifies the scope of the command. Specify one of the following:

ACCOUNT

Returns records for the entire account.

DATABASE, . DATABASE db_name

Returns records for the current database in use or for a specified database (db_name).

If you specify DATABASE without db_name and no database is in use, the keyword has no effect on the output.

Note

Using SHOW commands without an IN clause in a database context can result in fewer than expected results.

Objects with the same name are only displayed once if no IN clause is used. For example, if you have table t1 in schema1 and table t1 in schema2, and they are both in scope of the database context you’ve specified (that is, the database you’ve selected is the parent of schema1 and schema2), then SHOW TABLES only displays one of the t1 tables.

SCHEMA, . SCHEMA schema_name

Returns records for the current schema in use or a specified schema (schema_name).

SCHEMA is optional if a database is in use or if you specify the fully qualified schema_name (for example, db.schema).

If no database is in use, specifying SCHEMA has no effect on the output.

APPLICATION application_name, . APPLICATION PACKAGE application_package_name: Returns records for the named Snowflake Native App or application package.

Default: Depends on whether the session currently has a database in use:

Database: DATABASE is the default (that is, the command returns the objects you have privileges to view in the database).
No database: ACCOUNT is the default (that is, the command returns the objects you have privileges to view in your account).

Output¶

The command output provides user function properties and metadata in the following columns:

Column	Description
`created_on`	Timestamp at which the user-defined function (UDF) was created.
`name`	Name of the UDF.
`schema_name`	Name of the schema in which the UDF exists.
`is_builtin`	Always `N` for user-defined functions. See SHOW FUNCTIONS for a command to list all functions, including built-in functions.
`is_aggregate`	`Y` if the function is an aggregate function; `N` otherwise.
`is_ansi`	Not applicable currently.
`min_num_arguments`	Minimum number of arguments to the UDF.
`max_num_arguments`	Maximum number of arguments to the UDF.
`arguments`	Data types of the arguments and return value.
`description`	Description of the UDF.
`catalog_name`	Name of the database in which the UDF exists.
`is_table_function`	`Y` if the UDF is a table function; `N` otherwise.
`valid_for_clustering`	`Y` if the UDF can be used in a CLUSTER BY expression; `N` otherwise.
`is_secure`	`Y` if the UDF is a secure UDF; `N` otherwise.
`secrets`	Map of secret values specified by the function’s SECRETS parameter, where map keys are secret variable names and map values are secret object names.
`external_access_integrations`	Names of external access integrations specified by the function’s EXTERNAL_ACCESS_INTEGRATION parameter.
`is_external_function`	`Y` if the function is an external function; `N` otherwise. See SHOW EXTERNAL FUNCTIONS for a command to list external functions.
`language`	Programming language of the UDF (for example, `PYTHON` or `SQL`).
`is_memoizable`	`Y` if the function is memoizable; `N` otherwise.
`is_data_metric`	`Y` if the function is a data metric function; `N` otherwise.

Usage notes¶

The command doesn’t require a running warehouse to execute.
The command only returns objects for which the current user’s current role has been granted at least one access privilege.
The MANAGE GRANTS access privilege implicitly allows its holder to see every object in the account. By default, only the account administrator (users with the ACCOUNTADMIN role) and security administrator (users with the SECURITYADMIN role) have the MANAGE GRANTS privilege.

To post-process the output of this command, you can use the pipe operator or the RESULT_SCAN function. Both constructs treat the output as a result set that you can query.

The command returns a maximum of ten thousand records for the specified object type, as dictated by the access privileges for the role used to execute the command. Any records above the ten thousand records limit aren’t returned, even with a filter applied.

To view results for which more than ten thousand records exist, query the corresponding view (if one exists) in the Snowflake Information Schema.

Examples¶

Show all the UDFs that you have privileges to view in the current database:

SHOW USER FUNCTIONS LIKE 'ALLOWED_REGIONS%' IN SCHEMA;
