I have the following following SQL call that I make on a Pervasive V11 database. I'm looking to work it so that I only get one line for each Item Id.
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;
As it is now, I receive an error from the database if I don't have trx_type, stocked_by_factor, or unit_weight listed in the Group By clause.
Removing those fields results in this error:
Column invalid. Must be a group by column: trx_type in SELECT LIST.
Here are sample results of the complete SQL call:
ItemId Description QtyChangeP CostChangeP QtyChangeS CostChangeS QtyChangeA CostChangeA QtyChangeT CostChangeT WtPerFt

Any help is greatly appreciated. Thanks!!
The condition should be the argument to the sum()
:
sum(If(RTrim(trx_type) = 'P', change_quantity), 0) AS QtyChangeP,
Normally, this would be written using case
:
sum(case when RTrim(trx_type) = 'P' then change_quantity else 0 end) AS QtyChangeP,
Never mind... after hours of racking my brain, the answer was right in front of me. I just needed to turn the If() functions into SUM() functions.
Here's the working call:
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',
SUM(If(RTrim(trx_type) = 'A',inventory_history.change_quantity,0)) AS 'QtyChangeA',
SUM(If(RTrim(trx_type) = 'A',(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 'CostChangeA',
SUM(If(RTrim(trx_type) = 'T',inventory_history.change_quantity,0)) AS 'QtyChangeT',
SUM(If(RTrim(trx_type) = 'T',(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 'CostChangeT',
If(RTrim(inventory_categories.stocked_by_factor) = 'FT',inventory_items.unit_weight,'') AS 'WtPerFt'
