SQL Server Script to Rebuild/Reorganize Fragmented Indexes When on a database’s table frequently running INSERT, UPDATE or DELETE queries than we can see indexes on the particular table gets fragmented and the SQL query may run slower as they may choose the non-optimal execution plan. Most of the people asking about Does SQL Server rebuild index automatically or any rebuild criteria? But Rebuilding/Reorganize of fragmented Indexes not supported automatically because rebuilding the indexes is expansive operation so be careful to schedule rebuilding via SQL Server Agent. But hare we are adopting an approach to rebuild or Reorganize only the necessary Indexes instead of all index rebuild, As a general recommendation, the index needs to rebuild that gets fragment percentage more than 30% and reorganize the index that has fragment percentage greater than 10% and less than 30%. The below script rebuilding index one by one, so it won’t be an expansive operation on the production database. --- Rebuild/Reorganize Indexes CREATE TABLE #IndexRebuild ( DatabaseName SYSNAME, SchemaName SYSNAME, TableName SYSNAME, IndexName SYSNAME, [Fragmentation%] FLOAT ) INSERT INTO #IndexRebuild SELECT DB_NAME(DB_ID()) AS DatabaseName, ss.name AS SchemaName, OBJECT_NAME (s.object_id) AS TableName, i.name AS IndexName, s.avg_fragmentation_in_percent AS [Fragmentation%] FROM sys.dm_db_index_physical_stats(db_id(),NULL, NULL, NULL, 'SAMPLED') s INNER JOIN sys.indexes i ON s.[object_id] = i.[object_id] AND s.index_id = i.index_id INNER JOIN sys.objects o ON s.object_id = o.object_id INNER JOIN sys.schemas ss ON ss.[schema_id] = o.[schema_id] WHERE s.database_id = DB_ID() AND i.index_id != 0 AND s.record_count > 0 AND o.is_ms_shipped = 0 AND s.avg_fragmentation_in_percent > 10 DECLARE @RebuildSQL NVARCHAR(MAX) SET @RebuildSQL = '' SELECT @RebuildSQL = @RebuildSQL + CASE WHEN [Fragmentation%] > 30 THEN CHAR(10) + 'ALTER INDEX ' + QUOTENAME(IndexName) + ' ON ' + QUOTENAME(SchemaName) + '.' + QUOTENAME(TableName) + ' REBUILD;' WHEN [Fragmentation%] > 10 THEN CHAR(10) + 'ALTER INDEX ' + QUOTENAME(IndexName) + ' ON ' + QUOTENAME(SchemaName) + '.' + QUOTENAME(TableName) + ' REORGANIZE;' END FROM #IndexRebuild WHERE [Fragmentation%] > 10 DECLARE @StartOffset INT DECLARE @Length INT SET @StartOffset = 0 SET @Length = 4000 WHILE (@StartOffset < LEN(@RebuildSQL)) BEGIN PRINT SUBSTRING(@RebuildSQL, @StartOffset, @Length) SET @StartOffset = @StartOffset + @Length END PRINT SUBSTRING(@RebuildSQL, @StartOffset, @Length) EXECUTE sp_executesql @RebuildSQL DROP TABLE #IndexRebuild The scripts will work like a charm, You can create a stored procedure and can call the stored procedure via the SQL Server agent or via windows task scheduler.

How to make aside collapse when mobile resolution using bootstrap?

pradeepkumarjse

Im trying to make my aside menu collapse when using mobile resolutions so its not shown at all, but .collapse class is making my aside collapse in all resolutions, big and small ones. How can i change this to only collapse in small resolutions? There must be a way using bootstrap classes, otherwise bootstrap nav-bars couldn't collapse the way they do when using mobile resolutions.

Thank you
