snowflake.snowpark.functions.array_to_string

snowflake.snowpark.functions.array_to_string(array: Union[Column, str], separator: Union[Column, str]) → Column[source] (https://github.com/snowflakedb/snowpark-python/blob/v1.47.0/src/snowflake/snowpark/functions.py#L7424-L7450)

Returns an input ARRAY converted to a string by casting all values to strings (using TO_VARCHAR) and concatenating them (using the string from the second argument to separate the elements).

Parameters:

  • array – Column containing the ARRAY of elements to convert to a string.

  • separator – Column containing the string to put between each element (e.g. a space, comma, or other human-readable separator).

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()
