PowerShell / SQL Server / Generate SQL Script to Restore Multiple Transaction Logs

PowerShell / SQL Server / Generate SQL Script to Restore Multiple Transaction Logs
Restore multiple TRN logs using PowerShell. In this example I will show you really simple way how you can use PowerShell to restore multiple logs at once. After restoring full backup WITH NORECOVERY you need to figure it out last log sequence number of the last transaction in the backup set. TRN Log backups must be restored in the order in which they were created. Log backups contain log sequence numbers (LSN), and they must be restored in that particular order. There are few ways to find last LSN. USE msdb GO SELECT TOP 10 bck.database_name , bck.first_lsn , bck.last_lsn , bck.backup_start_date ,...

SQL Server / ALTER INDEX / CREATE INDEX Progress

SQL Server / ALTER INDEX / CREATE INDEX Progress
Creating a new and altering existing indexes on the big tables can be time-consuming. There is a simple way to see the progress of the CREATE / ALTER INDEX command. Since SQL Server 2014 we can use sys.dm_exec_query_profiles DMV to monitor real-time query progress. sys.dm_exec_query_profiles (SQL SERVER 2014 and above) “Monitors real-time query progress while the query is in execution. For example, use this DMV to determine which part of the query is running slow. Join this DMV with other system DMVs using the columns identified in the description field”   The first thing we need to...
