snowflake.core.user_defined_function.UserDefinedFunctionResource¶

class snowflake.core.user_defined_function.UserDefinedFunctionResource(name_with_args: str, collection_class: UserDefinedFunctionCollection)¶

Bases: UserDefinedFunctionResourceBase

Represents a reference to a Snowflake user defined function.

With this user defined function reference, you can create, drop, rename and fetch information about user defined functions.

Attributes

database¶

The DatabaseResource this reference belongs to.

fully_qualified_name¶

Return the fully qualified name of the object this reference points to.

root¶

The Root object this reference belongs to.

Methods

drop(if_exists: bool | None = None) → None¶

Delete a UDF.

Parameters:

if_exists (bool) – Parameter that specifies how to handle the request for a resource that does not exist: - true: The endpoint does not throw an error if the resource does not exist. It returns a 200 success response, but does not take any action on the resource. - false: The endpoint throws an error if the resource doesn’t exist.

drop_async(if_exists: bool | None = None) → PollingOperation[None]¶

An asynchronous version of drop().

Refer to PollingOperation for more information on asynchronous execution and the return type.

fetch() → UserDefinedFunction¶

Fetch a UDF.

fetch_async() → PollingOperation[UserDefinedFunction]¶

An asynchronous version of fetch().

Refer to PollingOperation for more information on asynchronous execution and the return type.

rename(target_name: str, target_database: str | None = None, target_schema: str | None = None, if_exists: bool | None = None) → None¶

Rename this user defined function.

Parameters:

  • target_name (str) – The new name of the user defined function

  • target_database (str, optional) – The database where the user defined function will be located

  • target_schema (str, optional) – The schema where the user defined function will be located

  • if_exists (bool, optional) – Check the existence of user defined function before rename

Examples

Renaming this user defined function using its reference:

>>> user_defined_function_reference.rename("my_other_user_defined_function")
Copy

Renaming this user defined function if it exists:

>>> user_defined_function_reference.rename("my_other_user_defined_function", if_exists=True)
Copy

Renaming this user defined function and relocating it to another schema within same database:

>>> user_defined_function_reference.rename(
...     "my_other_user_defined_function", target_schema="my_other_schema", if_exists=True
... )
Copy

Renaming this user defined function and relocating it to another database and schema:

>>> user_defined_function_reference.rename(
...     "my_other_user_defined_function",
...     target_database="my_other_database",
...     target_schema="my_other_schema",
...     if_exists=True,
... )
Copy
rename_async(target_name: str, target_database: str | None = None, target_schema: str | None = None, if_exists: bool | None = None) → PollingOperation[None]¶

An asynchronous version of rename().

Refer to PollingOperation for more information on asynchronous execution and the return type.
