Database Indexes

Databases use indexes on tables to locate data quickly. If there are large changes in data or volumes of data over time, maintenance may be required on the indexes.

Rebuild database indexes

DECLARE @TableName VARCHAR(255)
DECLARE @sql NVARCHAR(500)

DECLARE TableCursor CURSOR FOR
SELECT OBJECT_SCHEMA_NAME([object_id])+'.['+ name +']' AS TableName
FROM sys.tables

OPEN TableCursor
FETCH NEXT FROM TableCursor INTO @TableName
WHILE @@FETCH_STATUS = 0
BEGIN
	SET @sql = 'ALTER INDEX ALL ON ' + @TableName + ' REBUILD'
print (@sql)
	EXEC (@sql)
	FETCH NEXT FROM TableCursor INTO @TableName
END
CLOSE TableCursor
DEALLOCATE TableCursor
GO
