To get a rough view of how many rows, total, used and unused space each table has, in a sql server database you can run the following query:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 | USE {Database_Name}; GO SELECT t.Name AS TableName, s.Name AS SchemaName, p.Rows AS RowCounts, SUM(a.total_pages) * 8 AS TotalSpaceKB, SUM(a.used_pages) * 8 AS UsedSpaceKB, (SUM(a.total_pages) - SUM(a.used_pages)) * 8 AS UnusedSpaceKB FROM sys.tables t INNER JOIN sys.indexes i ON t.object_id = i.object_id INNER JOIN sys.partitions p ON i.object_id = p.object_id AND i.index_id = p.index_id INNER JOIN sys.allocation_units a ON p.partition_id = a.container_id LEFT OUTER JOIN sys.schemas s ON t.schema_id = s.schema_id WHERE t.Name NOT LIKE 'dt%' AND t.is_ms_shipped = 0 AND i.object_id > 255 GROUP BY t.Name, s.Name, p.Rows ORDER BY t.Name; GO |
Another way is using the stored procedure sp_spaceused which displays the number of rows, disk space reserved, and disk space used by a table, indexed view, or Service Broker queue in…
