snowflake.snowpark.functions.object_pick¶

snowflake.snowpark.functions.object_pick(obj: Union[Column, str], key1: Union[Column, str], *keys: Union[Column, str]) → Column[source] (https://github.com/snowflakedb/snowpark-python/blob/v1.16.0/src/snowflake/snowpark/functions.py#L5734-L5767)¶

Returns a new OBJECT containing some of the key-value pairs from an existing object.

To identify the key-value pairs to include in the new object, pass in the keys as arguments, or pass in an array containing the keys.

If a specified key is not present in the input object, the key is ignored.

Example::

>>> from snowflake.snowpark.functions import lit
>>> df = session.sql(
...     "select object_construct(a,b,c,d,e,f) as obj, k, v from "
...     "values('age', 21, 'zip', 21021, 'name', 'Joe', 'age', 0),"
...     "('age', 26, 'zip', 94021, 'name', 'Jay', 'age', 0) as T(a,b,c,d,e,f,k,v)"
... )
>>> df.select(object_pick(col("obj"), col("k"), lit("name")).alias("result")).show()
