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.

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).
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.
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 output column names for this command are generated in lowercase. If you consume a result set from this command with the pipe operator or the RESULT_SCAN function, use double-quoted identifiers for the column names in the query to ensure that they match the column names in the output that was scanned. For example, if the name of an output column is type, then specify "type" for the identifier.
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.
Show all the UDFs that you have privileges to view in the current database:
