無法在 %1 '%2' 上繼續執行索引 DDL 作業，因為這項作業與已經在物件上執行的另一項並行作業衝突。此並行作業可以是相同物件上的線上索引作業，或用來移動索引頁面的另一個並行作業，例如 DBCC SHRINKFILE。

Could not proceed with index DDL operation on %1 '%2' because it conflicts with another concurrent operation that is already in progress on the object. The concurrent operation could be an online index operation on the same object or another concurrent operation that moves index pages like DBCC SHRINKFILE.
