snowflake.snowpark.functions.vector_l2_distance¶
- snowflake.snowpark.functions.vector_l2_distance(v1: Union[Column, str], v2: Union[Column, str]) Column[source] (https://github.com/snowflakedb/snowpark-python/blob/v1.16.0/src/snowflake/snowpark/functions.py#L5793-L5809)¶
Returns the l2 distance between two vectors of equal dimension and element type.
- Example::
>>> from snowflake.snowpark.functions import vector_l2_distance >>> df = session.sql("select [1,2,3]::vector(int,3) as a, [2,3,4]::vector(int,3) as b") >>> df.select(vector_l2_distance(df.a, df.b).as_("dist")).show() ---------------------- |"DIST" | ---------------------- |1.7320508075688772 | ----------------------
