- snowflake.snowpark.functions.array_to_string(array: Union[Column, str], separator: Union[Column, str]) Column[source]¶

- Example::
>>> from snowflake.snowpark import Row >>> df = session.create_dataframe([Row(a=[1, True, "s"])]) >>> df.select(array_to_string("a", lit(",")).alias("result")).show() ------------ |"RESULT" | ------------ |1,true,s | ------------
