SQL Database Space/ Fragmentation

SQL Query to get space on Database

SELECT DISTINCT DB_NAME(dovs.database_id) DBName,
mf.physical_name PhysicalFileLocation,
dovs.logical_volume_name AS LogicalName,
dovs.volume_mount_point AS Drive,
CONVERT(INT,dovs.available_bytes/1048576.0) AS FreeSpaceInMB
FROM sys.master_files mf
CROSS APPLY sys.dm_os_volume_stats(mf.database_id, mf.FILE_ID) dovs
ORDER BY FreeSpaceInMB ASC

SQL Query to get Fragmentation of Indexes

SELECT
ps.database_id,
ps.OBJECT_ID,
object_name(ps.object_id) as ObjectName,
ps.index_id,
b.name,
ps.avg_fragmentation_in_percent
FROM sys.dm_db_index_physical_stats (DB_ID(), NULL, NULL, NULL, NULL) AS ps
INNER JOIN sys.indexes AS b ON ps.OBJECT_ID = b.OBJECT_ID
AND ps.index_id = b.index_id
WHERE ps.database_id = DB_ID()
ORDER BY ps.avg_fragmentation_in_percent DESC
