我想创建一个列表，显示每个食品的总量。我已经获得了想要的数据，但是，它在分组依据所包含的成分列中显示了多个具有相同值的单元格。
我已经尝试重建脚本，但是我已经尽力了。
SELECT "recipeingredients"."ingredient",
("recipeingredients"."amountperservekg" * SUM("transactionGC"."Unit_Qty_Sold")) as "Total Ingredient"
FROM public.recipemain
left join "recipelinkingpos" on "recipemain"."recipename" = "recipelinkingpos"."sendrecipe"
left join "recipeingredients" on "recipemain"."recipeid" = "recipeingredients"."recipeid"
left join "transactionGC" on "recipelinkingpos"."Product_Name" = "transactionGC"."Product_Name"
where
ingredient is not null
and
date_trunc('week',"transactionGC"."Date/Time")
between (now()- interval '8 days') and (now()-interval '1 days')
group by
"recipeingredients"."amountperservekg",
"recipeingredients"."ingredient"
order by "recipeingredients"."ingredient" asc;
上述脚本的结果。我只希望每种成分只有一个实例。
