Getting double entry in sql output

Question

I am executing the below sql statement but getting the repetition of the record. Below is the query for the same

select distinct ore.ORDER_RELEASE_GID order_release,
shbuy.SHIPMENT_GID Buy_Shipment,
shsel.SHIPMENT_GID Sell_Shipment,
shbuy.TRANSPORT_MODE_GID Buy_T_Mode,
shbuy.ATTRIBUTE10 Equipment_ID,
shsel.TRANSPORT_MODE_GID Sell_T_Mode,
shbuy.SERVPROV_GID Buy__Carrier,
shsel.SERVPROV_GID Sell__Carrier,
sst1.STOP_NUM Buy_stop_num,
sst2.STOP_NUM Sell_stop_num,
orig.LOCATION_NAME Origin,
orig.CITY Orig_City,
orig.PROVINCE_CODE Orig_State,
orig.POSTAL_CODE Orig_Zip,
dest.LOCATION_NAME Consignee,
dest.CITY Dest_City,
dest.PROVINCE_CODE Dest_State,
dest.POSTAL_CODE Dest_Zip
from ship_unit su, s_ship_unit ssu1, s_ship_unit ssu2, shipment_stop_d ssd1,
shipment_stop ss1, shipment_stop_d ssd2, shipment_stop sst1,
shipment_stop sst2, shipment shbuy, shipment shsel,
order_release ore, location orig, location dest
where su.SHIP_UNIT_GID = ssu1.SHIP_UNIT_GID
and su.SHIP_UNIT_GID = ssu2.SHIP_UNIT_GID
and ssu1.S_SHIP_UNIT_GID = ssd1.S_SHIP_UNIT_GID
and ssu2.S_SHIP_UNIT_GID = ssd2.S_SHIP_UNIT_GID
and ssd1.SHIPMENT_GID = shbuy.SHIPMENT_GID
and ssd2.SHIPMENT_GID = shsel.SHIPMENT_GID
and su.ORDER_RELEASE_GID = ore.ORDER_RELEASE_GID
and shbuy.SHIPMENT_GID = sst1.SHIPMENT_GID
and shsel.SHIPMENT_GID = sst2.SHIPMENT_GID
and ssd1.STOP_NUM = sst1.STOP_NUM
and ssd2.STOP_NUM = sst2.STOP_NUM
and ssd1.STOP_NUM > 1
and ssd2.STOP_NUM > 1
and shbuy.PERSPECTIVE = 'B'
and shsel.PERSPECTIVE = 'S'
-- Common Area
and ss1.LOCATION_GID = orig.LOCATION_GID
and sst1.LOCATION_GID = dest.LOCATION_GID
and shbuy.SHIPMENT_GID = ss1.SHIPMENT_GID
and ss1.STOP_NUM = 1
order by buy_shipment, order_release

The output is as followed

Please let me know what all chnages i need to make in the sql so that it fetches just 1 order release and not twice or thrice as shown in the output.

Thanks Mrugen

Hi, we can see that the two row have different Consignee. At the extreme right of your image... how to choose one? — zip, Feb 01 '20 at 13:35
Hi @ zip the consignee name is different but what i want is that it should pick the lowest stop number if you consider the image then it should just consider the buy_stop_num = 2 , but the query takes buy_stop_num = 3 as well. So , how to restrict this like it should just take the lowest buy_stop_num value .. — mrugen munshi, Feb 01 '20 at 13:47

Use rownum for that to filter ore.ORDER_RELEASE_GID and get the lowest buy_stop_num

select distinct ore.ORDER_RELEASE_GID order_release,
shbuy.SHIPMENT_GID Buy_Shipment,
shsel.SHIPMENT_GID Sell_Shipment,
shbuy.TRANSPORT_MODE_GID Buy_T_Mode,
shbuy.ATTRIBUTE10 Equipment_ID,
shsel.TRANSPORT_MODE_GID Sell_T_Mode,
shbuy.SERVPROV_GID Buy__Carrier,
shsel.SERVPROV_GID Sell__Carrier,
sst1.STOP_NUM Buy_stop_num,
sst2.STOP_NUM Sell_stop_num,
orig.LOCATION_NAME Origin,
orig.CITY Orig_City,
orig.PROVINCE_CODE Orig_State,
orig.POSTAL_CODE Orig_Zip,
dest.LOCATION_NAME Consignee,
dest.CITY Dest_City,
dest.PROVINCE_CODE Dest_State,
dest.POSTAL_CODE Dest_Zip
ROW_NUMBER() OVER(partition BY ore.ORDER_RELEASE_GID ORDER BY ore.ORDER_RELEASE_GID, dest.LOCATION_NAME ASC) AS Row
from ship_unit su, s_ship_unit ssu1, s_ship_unit ssu2, shipment_stop_d ssd1,
shipment_stop ss1, shipment_stop_d ssd2, shipment_stop sst1,
shipment_stop sst2, shipment shbuy, shipment shsel,
order_release ore, location orig, location dest
where su.SHIP_UNIT_GID = ssu1.SHIP_UNIT_GID
and su.SHIP_UNIT_GID = ssu2.SHIP_UNIT_GID
and ssu1.S_SHIP_UNIT_GID = ssd1.S_SHIP_UNIT_GID
and ssu2.S_SHIP_UNIT_GID = ssd2.S_SHIP_UNIT_GID
and ssd1.SHIPMENT_GID = shbuy.SHIPMENT_GID
and ssd2.SHIPMENT_GID = shsel.SHIPMENT_GID
and su.ORDER_RELEASE_GID = ore.ORDER_RELEASE_GID
and shbuy.SHIPMENT_GID = sst1.SHIPMENT_GID
and shsel.SHIPMENT_GID = sst2.SHIPMENT_GID
and ssd1.STOP_NUM = sst1.STOP_NUM
and ssd2.STOP_NUM = sst2.STOP_NUM
and ssd1.STOP_NUM > 1
and ssd2.STOP_NUM > 1
and shbuy.PERSPECTIVE = 'B'
and shsel.PERSPECTIVE = 'S'
-- Common Area
and ss1.LOCATION_GID = orig.LOCATION_GID
and sst1.LOCATION_GID = dest.LOCATION_GID
and shbuy.SHIPMENT_GID = ss1.SHIPMENT_GID
and ss1.STOP_NUM = 1
and Row = 1
order by buy_shipment, order_release
