snowflake.snowpark.Session.sql¶

Session.sql(query: str, params: Optional[Sequence[Any]] = None) → DataFrame[source] (https://github.com/snowflakedb/snowpark-python/blob/release-v1.6.1/src/snowflake/snowpark/session.py#L1639-L1676)¶

Returns a new DataFrame representing the results of a SQL query. You can use this method to execute a SQL statement. Note that you still need to call DataFrame.collect() to execute this query in Snowflake.

Parameters:

query – The SQL statement to execute.
params – binding parameters. We only support qmark bind variables. For more information, check https://docs.snowflake.cn/en/developer-guide/python-connector/python-connector-example#qmark-or-numeric-binding

Example:

>>> # create a dataframe from a SQL query
>>> df = session.sql("select 1/2")
>>> # execute the query
>>> df.collect()
[Row(1/2=Decimal('0.500000'))]

>>> # Use params to bind variables
>>> session.sql("select * from values (?, ?), (?, ?)", params=[1, "a", 2, "b"]).sort("column1").collect()
[Row(COLUMN1=1, COLUMN2='a'), Row(COLUMN1=2, COLUMN2='b')]
