INSERT INTO xml_demo (object_col)
    SELECT
        '<Root>

<Features>
  <Warranty>1 year parts and labor</Warranty>
  <Maintenance>3 year parts and labor extended maintenance is available</Maintenance>
</Features>
</ProductDescription>
</Root>';

INSERT INTO xml_demo (object_col)
    SELECT
        '<Root>
<ProductDescription ProductID="2" ProductName="Skate">

</Features>
</ProductDescription>
</Root>';

SELECT
    xml_demo.object_col.query('/Root/ProductDescription/Features/Warranty') as Warranty,
    xml_demo.object_col.query('/Root/ProductDescription/Features/Maintenance') as Maintenance
from xml_demo;

Snowflake SQL

OUT -> SqlServer_01.sql
CREATE OR REPLACE TABLE xml_demo (

COMMENT = '{"origin":"sf_sc","name":"snowconvert","version":{"major":1, "minor":0},{"attributes":{"component":"transact"}}'
;

INSERT INTO xml_demo (object_col)
SELECT
    PARSE_XML(
    '<Root>
