Mixing
Update Rows based on Select from same Table
I have PervasiveSQL DB with a table with Item Selling Costs Listed by StoreCode. Data looks like the data below
StoreCore ItemCode LastPurchAmt
001 2201 78.75
002 2201 75.0
003 2201 75.0
05 2201 0.0
07 2201 75.0
08 2201 78.75
09 2201 75.0
10 2201 75.0
They requested that i set the LastPurchAmt for each item = to the LastPurchAmt of Store 001.
I've read through more update examples and tried more variations for the update statement than i care to remember but i just can't seem to get this.
This Statement:
Update MultiStoreTrn as UpdateTrn
join (select ItemCode, LastPurchAmt from MultiStoreTrn where StoreCode = '001') as ValueTrn
on UpdateTrn.ItemCode = ValueTrn.ItemCode
set UpdateTrn.LastPurchAmt = ValueTrn.LastPurchAmt
where UpdateTrn.StoreCode <> '001';
Returns a Error Message:
[LNA][Pervasive][ODBC Engine Interface]A table or view name must be specified for update.
This Code:
Update MultiStoreTrn as UpdateTrn
set UpdateTrn.LastPurchAmt = (Select LastPurchAmt from MultiStoreTrn where StoreCode = 001 and ItemCode = UpdateTrn.ItemCode);
Works but it updates all the values to Zero
I have tried this code as well:
Update MultiStoreTrn
set MultiStoreTrn.LastPurchAmt = ValueTrn.LastPurchAmt
from (select ItemCode, LastPurchAmt from MultiStoreTrn where storecode = 001) as ValueTrn
where MultiStoreTrn.StoreCode <> 001 and MultiStoreTrn.ItemCode = ValueTrn.ItemCode;
It runs without errors but updates nothing.
Any ideas what i'm missing :(
Thanks for the Time Reading and Answering...

What version of Pervasive PSQL are you using? I ran through your queries and the last two worked for me. I think the last query is the best option
