問題現象：
DPF環境下db2diag.log中有Error級別的報錯， FUNCTION爲sqluCTable::iGetTableInfoForLoadQuery
問題原因：
正常情況下，DPF環境，連接到任意一個節點即可對錶做增刪改操作，無論該節點是否有該表的定義。
但load query是例外，如果應用連接到某個節點上對一張表發出了load query命令，但該表所在的表空間所在的 partition group 並未包含該節點（也就是該表在這個節點上未定義），那麼load query會失敗，報錯 SQL6024C
問題重現：
創建一個分區數據庫，有0、1、2共三個分區，然後在1和2分區上創建表t1, 那麼在0號節點可以增刪改t1，但不能load query.
