SHOW USER FUNCTIONS¶

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

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.

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).

Usage notes¶

Columns that start with the prefix is_ return either Y (yes) or N (no).
The command does not require a running warehouse to execute.
The command returns a maximum of 10K records for the specified object type, as dictated by the access privileges for the role used to execute the command; any records above the 10K limit are not returned, even with a filter applied.

To view results for which more than 10K records exist, query the corresponding view (if one exists) in the Snowflake Information Schema.

To post-process the output of this command, you can use the RESULT_SCAN function, which treats the output as a table that can be queried.

Output¶

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

Column	Description
`created_on`	The timestamp at which the user-defined function (UDF) was created.
`name`	The name of the UDF.
`schema_name`	The name of the schema in which the UDF exists.
`is_builtin`	Whether the UDF is built-in (always false for UDFs).
`is_aggregate`	True if the UDF is an aggregate function; false otherwise.
`is_ansi`	Not applicable currently.
`min_num_arguments`	The minimum number of arguments to the UDF.
`max_num_arguments`	The maximum number of arguments to the UDF.
`arguments`	The data types of the arguments and of the return value.
`description`	Description of the UDF.
`catalog_name`	The name of the database in which the UDF exists.
`is_table_function`	True if the UDF is a table function; false otherwise.
`valid_for_clustering`	True if the UDF can be used in a CLUSTER BY expression; false otherwise.
`is_secure`	True if the UDF is a secure UDF; false otherwise.
`is_external_function`	Y (yes) if the function is an external function, N (no) otherwise.
`language`	Specifies the language of the UDF (e.g. SQL).
`is_memoizable`	Y (yes) if the function is memoizable, N (no) otherwise.
`is_data_metric`	Y (is) if the function is a data metric function, N (no) otherwise.

Examples¶

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

show user functions like 'ALLOWED_REGIONS%' in schema;
