修改IList查询语句

Question

我有以下语句，我想对其进行修改以不选择所有表。

1. 在customerItemNo中排除2列manufacturerItemNo和if，并且
2. 在customerItemNoAppend中排除2列manufacturerItemNoAppend和else if。

我该怎么办？

if (p.UserInternal == 'Y' && p.UserActive == 'Y')
    inventorySummary = DataProvider.SelectCondition<Q_TBL_INVENTORY_SUMMARY>
(r => r.InventoryLocationNo == location);

else if (p.UserInternal != 'Y' && p.UserActive == 'Y')
    inventorySummary = DataProvider.SelectCondition<Q_TBL_INVENTORY_SUMMARY>
(r => r.InventoryLocationNo == location && (r.CustomerID == customerID || r.CustomerID == " "));

else
    inventorySummary = new List<Q_TBL_INVENTORY_SUMMARY>();
