SHOW EXTERNAL FUNCTIONS¶
Lists all the external functions created for your account.
For more information, see Writing external functions.
Syntax¶
SHOW EXTERNAL FUNCTIONS [ LIKE '<pattern>' ]
[ IN { 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:
APPLICATION application_name, .APPLICATION PACKAGE application_package_nameReturns records for the named Snowflake Native App or application package.
Usage notes¶
The commands SHOW FUNCTIONS and SHOW USER FUNCTIONS also display information about external functions.
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 RESULT_SCAN function, which treats the output as a table that can be queried. You can also use the pipe operator to query the output of this command.
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¶
