snowflake.snowpark.functions.object_construct_keep_null(*key_values: Union[Column, str]) → Column[source] (https://github.com/snowflakedb/snowpark-python/blob/v1.47.0/src/snowflake/snowpark/functions.py#L7716-L7744)¶

Returns an object containing the contents of the input (i.e. source) object with one or more keys removed.

Example:

>>> from snowflake.snowpark.types import StructType, StructField, VariantType, StringType
>>> df = session.create_dataframe(
...     [["key_1", "one"], ["key_2", None]],
...     schema=StructType([StructField("k", StringType()), StructField("v", VariantType())])
... )
>>> df.select(object_construct_keep_null(col("k"), col("v")).alias("result")).show()
