  In SQL Server database, there is a table InventDim with two indexes: Idx1 with index columns (DataAreaID, BatchID) and Idx2 with index columns (DataAreaID, BatchID, InventSizeID). Is it possible to drop Idx1 if Idx2 already exists and covers all the columns in Idx1? thanks a lot!

  Duplicate question. See https://www.sqlservercentral.com/forums/topic/how-to-determine-if-we-can-delete-the-index-can-be-removed for answer.
