snowflake.core.task.StoredProcedureCall

class snowflake.core.task.StoredProcedureCall(func: Callable[[...], Any] | StoredProcedure, *, args: List[Any] | None = None, return_type: DataType | None = None, input_types: List[DataType] | None = None, stage_location: str | None = None, imports: List[str | Tuple[str, str]] | None = None, packages: List[str | ModuleType] | None = None)

Bases: object

Represents a procedure call used as a task’s definition.

Parameters:

  • func –

    When it’s a Callable, typically a function, an anonymous stored procedure will be created as the Task’s definition by using this Callable. Note that the first parameter of your function should be a snowpark Session.

    When it’s a StoredProcedure, it will be converted to a SQL to call an existing stored procedure. The StoredProcedure must be a permanent one instead of a temporary one because a Task will run in a different session than the session that creates the Task. A temporary one won’t be accessible from that session that runs the Task.

  • args – The arguments to call the stored procedure when func is a StoredProcedure.

  • return_type – A DataType representing the return data type of the stored procedure. Optional if type hints are provided.

  • input_types – A list of DataType representing the input data types of the stored procedure. Optional if type hints are provided.

  • stage_location – The stage location where the Python file for the anonymous stored procedure and its dependencies should be uploaded. It must be a permanent location because a Task will run in a different session than the session that creates the Task. A temporary one won’t be accessible from that session that runs the Task.

  • imports – A list of imports that only apply to this stored procedure. You can use a string to represent a file path (similar to the path argument in add_import()) in this list, or a tuple of two strings to represent a file path and an import path (similar to the import_path argument in add_import()). These stored procedure-level imports will override the session-level imports added by add_import().

  • packages – A list of packages that only apply to this stored procedure. These stored procedure-level packages will override the session-level packages added by add_packages() and add_requirements().

Methods

__init__(func: Callable[[...], Any] | StoredProcedure, *, args: List[Any] | None = None, return_type: DataType | None = None, input_types: List[DataType] | None = None, stage_location: str | None = None, imports: List[str | Tuple[str, str]] | None = None, packages: List[str | ModuleType] | None = None) → None
