Snowpark Session¶

Session

Session(conn[, options])

Establishes a connection with a Snowflake database and provides methods for creating DataFrames and accessing objects for working with files in stages.

SessionBuilder

`Session.SessionBuilder.app_name`(app_name)	Adds the app name to the `SessionBuilder` to set in the query_tag after session creation
`Session.SessionBuilder.config`(key, value)	Adds the specified connection parameter to the `SessionBuilder` configuration.
`Session.SessionBuilder.configs`(options)	Adds the specified `dict` of connection parameters to the `SessionBuilder` configuration.
`Session.SessionBuilder.create`()	Creates a new Session.
`Session.SessionBuilder.getOrCreate`()	Gets the last created session or creates a new one if needed.

`Session.get_imports`()	Returns a list of imports added for user defined functions (UDFs).
`Session.get_packages`()	Returns a `dict` of packages added for user-defined functions (UDFs).
`Session.get_session_stage`([statement_params])	Returns the name of the temporary stage created by the Snowpark library for uploading and storing temporary artifacts for this session.
`Session.query_history`()	Create an instance of `QueryHistory` as a context manager to record queries that are pushed down to the Snowflake database.
`Session.range`(start[, end, step])	Creates a new DataFrame from a range of numbers.
`Session.remove_import`(path)	Removes a file in stage or local file from the imports of a user-defined function (UDF).
`Session.remove_package`(package)	Removes a third-party package from the dependency list of a user-defined function (UDF).
`Session.replicate_local_environment`([...])	Adds all third-party packages in your local environment as dependencies of a user-defined function (UDF).
`Session.sql`(query[, params])	Returns a new DataFrame representing the results of a SQL query.
`Session.table`(name)	Returns a Table that points the specified table.
`Session.table_function`(func_name, ...)	Creates a new DataFrame from the given snowflake SQL table function.
