Registers a Python function as a Snowflake Python stored procedure and returns the stored procedure. The usage, input arguments, and return value of this method are the same as they are for sproc(), but register() cannot be used as a decorator. See examples in StoredProcedureRegistration.

Parameters:

func – A Python function used for creating the stored procedure. Note that the first parameter of your function should be a snowpark Session.
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.
name – A string or list of strings that specify the name or fully-qualified object identifier (database name, schema name, and function name) for the stored procedure in Snowflake, which allows you to call this stored procedure in a SQL command or via call(). If it is not provided, a name will be automatically generated for the stored procedure. A name must be specified when is_permanent is True.
is_permanent – Whether to create a permanent stored procedure. The default is False. If it is True, a valid stage_location must be provided.
stage_location – The stage location where the Python file for the stored procedure and its dependencies should be uploaded. The stage location must be specified when is_permanent is True, and it will be ignored when is_permanent is False. It can be any stage other than temporary stages and external stages.
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().
replace – Whether to replace a stored procedure that already was registered. The default is False. If it is False, attempting to register a stored procedure with a name that already exists results in a SnowparkSQLException exception being thrown. If it is True, an existing stored procedure with the same name is overwritten.
if_not_exists – Whether to skip creation of a stored procedure the same procedure is already registered. The default is False. if_not_exists and replace are mutually exclusive and a ValueError is raised when both are set. If it is True and a stored procedure is already registered, the registration is skipped.
parallel – The number of threads to use for uploading stored procedure files with the PUT command. The default value is 4 and supported values are from 1 to 99. Increasing the number of threads can improve performance when uploading large stored procedure files.
execute_as – What permissions should the procedure have while executing. This supports caller, or owner for now.
strict – Whether the created stored procedure is strict. A strict stored procedure will not invoke the stored procedure if any input is null. Instead, a null value will always be returned. Note that the stored procedure might still return null for non-null inputs.
statement_params – Dictionary of statement level parameters to be set while executing this action.
source_code_display – Display the source code of the stored procedure func as comments in the generated script. The source code is dynamically generated therefore it may not be identical to how the func is originally defined. The default is True. If it is False, source code will not be generated or displayed.
