A bookings project now requires the same data extract - but from an SQL Server database - instead of Oracle. Can anyone assist converting the following into SQL Server syntax?
SELECT *
FROM (
SELECT o.ot_outlet_code
,v.lab_site_code ot_outlet_code
,v.brand
,v.region
, bd.cd_day_date booking_date, dd.cd_day_date dining_date
, f.last_change_date, f.created_date
, f.modified_date, t15.ts_timeslot_desc
, t.TIME, s.session_type
, tbs.booking_status, f.ADDED_BY_USER
, bp.product, bs.booking_source
, f.SPECIAL_OFFER, f.SEATING_PREFERENCE
, f.Tables_guest_id, covers
, booking_occurrence, breakfast_flag
, row_number() OVER (PARTITION BY f.Tables_guest_id ORDER BY f.last_change_date DESC, f.last_change_time DESC) rank_latest_record
, f.title, f.emailoptout
, f.MOBILE_OPT_IN, f.HIGH_CHAIR_COVERS
, f.GUEST_TYPE, f.Booking_ID
FROM owbi.whs_fact_rest_booking f
, owbi.whs_dim_cal_date bd
, owbi.whs_dim_cal_date dd
, owbi.whs_dim_bat_booking_source bs
, owbi.whs_dim_time_of_day t
, owbi.whs_dim_bat_product bp
, owbi.whs_dim_15_timeslot t15
, owbi.whs_dim_bat_booking_status tbs
, owbi.whs_dim_bat_session s
, owbi.bat_restaurants_v v
WHERE f.whs_dim_outlet = v.outlet
AND f.whs_dim_booking_date = bd.dimension_Key
AND f.whs_dim_dining_date = dd.dimension_key
AND f.whs_dim_bat_session = s.dimension_key
AND f.whs_dim_bat_booking_status = tbs.dimension_key
AND f.whs_dim_bat_product = bp.dimension_Key
AND f.whs_dim_bat_booking_source = bs.dimension_key
AND f.whs_dim_booking_time = t.dimension_Key
AND f.whs_dim_dining_15_timeslot = t15.dimension_key
AND dd.ey_year_code in ('2018')
AND f.whs_dim_dining_date >= 20170303
)
WHERE rank_latest_record = 1
ORDER BY BOOKING_DATE DESC;
The derived table must have an alias. eg
SELECT *
FROM (
SELECT o.ot_outlet_code
,v.lab_site_code ot_outlet_code
,v.brand
,v.region
, bd.cd_day_date booking_date, dd.cd_day_date dining_date
, f.last_change_date, f.created_date
, f.modified_date, t15.ts_timeslot_desc
, t.TIME, s.session_type
, tbs.booking_status, f.ADDED_BY_USER
, bp.product, bs.booking_source
, f.SPECIAL_OFFER, f.SEATING_PREFERENCE
, f.Tables_guest_id, covers
, booking_occurrence, breakfast_flag
, row_number() OVER (PARTITION BY f.Tables_guest_id ORDER BY f.last_change_date DESC, f.last_change_time DESC) rank_latest_record
, f.title, f.emailoptout
, f.MOBILE_OPT_IN, f.HIGH_CHAIR_COVERS
, f.GUEST_TYPE, f.Booking_ID
FROM owbi.whs_fact_rest_booking f
, owbi.whs_dim_cal_date bd
, owbi.whs_dim_cal_date dd
, owbi.whs_dim_bat_booking_source bs
, owbi.whs_dim_time_of_day t
, owbi.whs_dim_bat_product bp
, owbi.whs_dim_15_timeslot t15
, owbi.whs_dim_bat_booking_status tbs
, owbi.whs_dim_bat_session s
, owbi.bat_restaurants_v v
WHERE f.whs_dim_outlet = v.outlet
AND f.whs_dim_booking_date = bd.dimension_Key
AND f.whs_dim_dining_date = dd.dimension_key
AND f.whs_dim_bat_session = s.dimension_key
AND f.whs_dim_bat_booking_status = tbs.dimension_key
AND f.whs_dim_bat_product = bp.dimension_Key
AND f.whs_dim_bat_booking_source = bs.dimension_key
AND f.whs_dim_booking_time = t.dimension_Key
AND f.whs_dim_dining_15_timeslot = t15.dimension_key
AND dd.ey_year_code in ('2018')
AND f.whs_dim_dining_date >= 20170303
) dt
WHERE rank_latest_record = 1
ORDER BY BOOKING_DATE DESC;
In SQL Server it's considered poor form not use ANSI-style JOINs, although it's perfectly legal for inner joins to write them as a cross-join with the join criteria in the WHERE clause.
And it's generally better to use CTEs instead of subqueries/inline views/derived tables in the FROM clause.
