If you mean In-game Item Mall purchase log, you can find it here:
Code:
[PS_GameData].[dbo].[PointLog]
I just wrote this for you to use;
Code:
SELECT
C.CharID,
C.CharName,
PtL.UsePoint AS PointCost,
PtL.ProductCode,
PtL.TargetName,
PL.ProductName,
PtL.UseDate
FROM [PS_GameData].[dbo].[PointLog] as PtL
inner join [PS_GameDefs].[dbo].[ProductList] as PL on PtL.ProductCode=PL.ProductCode
inner join [PS_GameDefs].[dbo].[Items] AS I on PL.ItemID1=I.ItemID
inner join [PS_GameData].[dbo].[Chars] AS C on C.CharID=PtL.CharID
Here's an example of what you'll see:
You can add more columns to see what's inside the package etc, hope it helps!
