So I checkout a branch and start writing SQL using
that usually looks like :
{{
config(
alias='cool_data_mart_name',
materialized: table
)
}}
WITH fact_table AS (
SELECT * FROM {{ref('fact_table_name')}} WHERE [condition]
),
dimention_table_1 AS (
SELECT
{{ dbt_utils.star(
from=ref('dimention_table_1_name'),
except=[UNWANTED_COLUMN_NAMES],
, relation_alias='d1'
)}},
FROM
{{ref('dimention_table_1_name')}} AS d1
WHERE
[condition]
),
dimention_table_2 AS (
SELECT * FROM {{ref('dimention_table_2_name')}} WHERE [condition]
),
final AS (
SELECT
f.col1,
d1.*,
COALESCE(d2.col123, 'default_value') AS col123,
ROW_NUMBER() OVER( PARTITION BY id ORDER BY event_at DESC) AS deduplicate
FROM
fact_table AS f
INNER JOIN
dimention_table_1 AS d1
ON
f.foreign_1 = d1.primary
LEFT JOIN
dimention_table_2 AS d2
ON
f.foreign_2 = d2.primary
WHERE
[insert mart conditions]
QUALIFY
deduplicate = 1
)
SELECT * FROM final
