Build Main phase The data is scanned, sorted, merged, and inserted into the target in bulk load operations. Concurrent user select, insert, update, and delete operations are applied to both the pre-existing indexes and any new indexes being built. IS INDEX_BUILD_INTERNAL_RESOURCE** Final Sh...
The target or targets is the new index (or heap) or a set of new indexes that is being created or rebuilt. User insert, update, and delete operations to the source are applied by the SQL Server Database Engine to the target during the index operation. For example, if the online index...
SQL Server provides a significant amount of index information via Dynamic Management Views (DMVs). The dm_db_index_usage_stats DMV displays essential information about index usage, and it can be a useful tool in identifying unused SQL Server indexes. When an index is used for the first time,...
Well, these 2300 indexes exists on a server, not on one db I've overdone a little; this server holds one real DB and its test_version. I allready have generated script of indexes, but I cann't find a way how to drop all indexes, pk and fk from particular db. Regan Galbraith ...
Nonclustered– this is the most common type in SQL Server and typically more than one on a single table. The maximum number of nonclustered indexes vary depending on the SQL Server version but the number goes e.g. in SQL Server 2016 as high as 999 per table. Unlike clustered indexes, ...

When an index is built, statistics are collected for use in ranking. The process of building a full-text catalog does not directly result in a single index structure. Instead, the Full-Text Engine for SQL Server creates intermediate indexes as data is indexed. The Full-Text Engine then merge...
SQL Server databases with multiple filegroups can be restored in stages using piecemeal restore. Thepiecemeal restoreworks quite similar as the normal restore operation utilizing the three phases; data copy, redo and undo. You can perform a restore of one of your filegroups while your database ...
