SQL Server

Input

IN -> SqlServer_01.sql

CREATE TABLE xml_demo(object_col XML);

INSERT INTO xml_demo (object_col)
    SELECT
        '<Root>
<ProductDescription ProductID="1" ProductName="Road Bike">
<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>
  <Warranty>1 year parts and labor</Warranty>
  <Maintenance>3 year parts and labor extended maintenance is available</Maintenance>
</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;

Output

 Warranty                                     | Maintenance                                                                          |
----------------------------------------------+--------------------------------------------------------------------------------------+
<Warranty>1 year parts and labor</Warranty>   | <Maintenance>3 year parts and labor extended maintenance is available</Maintenance>  |
<Warranty>1 year parts and labor</Warranty>   | <Maintenance>3 year parts and labor extended maintenance is available</Maintenance>  |

Snowflake SQL

Input

OUT -> SqlServer_01.sql

CREATE OR REPLACE TABLE xml_demo (
    object_col VARIANT !!!RESOLVE EWI!!! /*** SSC-EWI-0036 - XML DATA TYPE CONVERTED TO VARIANT ***/!!!
)
COMMENT = '{"origin":"sf_sc","name":"snowconvert","version":{"major":1, "minor":0},{"attributes":{"component":"transact"}}'

Output
