Pervasive PSQL GROUP BY句

Question

私はPervasive V11データベースで以下のSQL呼び出しを行います。 私はそれを働かせて、アイテムIDごとに1行しか得られないようにしています。

SELECT 
    inventory_history.item_id AS 'ItemId', 
    RTrim(inventory_items.item_name) AS 'Description', 
    If(RTrim(trx_type) = 'P',SUM(change_quantity),'') AS 'QtyChangeP', 
    If(RTrim(trx_type) = 'P',SUM(history_cost_01+history_cost_02+history_cost_03+history_cost_04+history_cost_05+history_cost_06+history_cost_07+history_cost_08+history_cost_09+history_cost_10+history_cost_11+history_cost_12),'') AS 'CostChangeP', 
    If(RTrim(trx_type) = 'S',SUM(change_quantity),'') AS 'QtyChangeS', 
    If(RTrim(trx_type) = 'S',SUM(history_cost_01+history_cost_02+history_cost_03+history_cost_04+history_cost_05+history_cost_06+history_cost_07+history_cost_08+history_cost_09+history_cost_10+history_cost_11+history_cost_12),'') AS 'CostChangeS', 
    If(RTrim(trx_type) = 'A',SUM(change_quantity),'') AS 'QtyChangeA', 
    If(RTrim(trx_type) = 'A',SUM(history_cost_01+history_cost_02+history_cost_03+history_cost_04+history_cost_05+history_cost_06+history_cost_07+history_cost_08+history_cost_09+history_cost_10+history_cost_11+history_cost_12),'') AS 'CostChangeA', 
    If(RTrim(trx_type) = 'T',SUM(change_quantity),'') AS 'QtyChangeT', 
    If(RTrim(trx_type) = 'T',SUM(history_cost_01+history_cost_02+history_cost_03+history_cost_04+history_cost_05+history_cost_06+history_cost_07+history_cost_08+history_cost_09+history_cost_10+history_cost_11+history_cost_12),'') AS 'CostChangeT', 
    If(RTrim(inventory_categories.stocked_by_factor) = 'FT',inventory_items.unit_weight,'') AS 'WtPerFt' 
FROM 
    inventory_history 
INNER JOIN 
    inventory_items ON inventory_history.item_id = inventory_items.item_id 
INNER JOIN 
    inventory_categories ON inventory_items.category_id = inventory_categories.category_id 
WHERE 
    trx_date>'20170731' 
GROUP BY 
    inventory_history.item_id, inventory_items.item_name, trx_type, stocked_by_factor, unit_weight; 

それが今であると私はtrx_type、stocked_by_factor、またはunit_weightは、GROUP BY句にリストされていない場合、私は、データベースからのエラーを受け取ります。これらのフィールドを削除する

は、このエラーが発生：すべてのヘルプは大歓迎です

：ここ

Column invalid. Must be a group by column: trx_type in SELECT LIST.

は完全なSQLの呼び出しのサンプル結果です。ありがとう!!

Answer 1

気にしないで...私の脳をラッキングの時間後に、答えは私の目の前にあった。私は、If（）関数をSUM（）関数に変える必要がありました。

は、ここでの作業コールです：

SELECT 
    inventory_history.item_id AS 'ItemId', 
    RTrim(inventory_items.item_name) AS 'Description', 
    SUM(If(RTrim(trx_type) = 'P',inventory_history.change_quantity,0)) AS 'QtyChangeP', 
    SUM(If(RTrim(trx_type) = 'P',(history_cost_01+history_cost_02+history_cost_03+history_cost_04+history_cost_05+history_cost_06+history_cost_07+history_cost_08+history_cost_09+history_cost_10+history_cost_11+history_cost_12),0)) AS 'CostChangeP', 
    SUM(If(RTrim(trx_type) = 'S',inventory_history.change_quantity,0)) AS 'QtyChangeS', 
    SUM(If(RTrim(trx_type) = 'S',(history_cost_01+history_cost_02+history_cost_03+history_cost_04+history_cost_05+history_cost_06+history_cost_07+history_cost_08+history_cost_09+history_cost_10+history_cost_11+history_cost_12),0)) AS 'CostChangeS',

Answer 2

条件がsum()の引数でなければなりません：

sum(If(RTrim(trx_type) = 'P', change_quantity), 0) AS QtyChangeP, 

通常、これはcaseを使って書くことになります。

sum(case when RTrim(trx_type) = 'P' then change_quantity else 0 end) AS QtyChangeP,
