Measure SQL tables with ROWCOUNTS and STORAGE

With custom SQL line of business databases it can be helpful to enumerate all tables and row counts for each.   The below TSQL will create a new VIEW named “RowCounts” for that purpose.   I’d suggest adding this to any custom SQL database for easy data quality checks and monitoring.

Cheers!  

TSQL RowCount

CREATE VIEW RowCounts AS (
SELECT o.NAME,
  i.rowcnt 
FROM sysindexes AS i
INNER JOIN sysobjects AS o
ON i.id = o.id
WHERE i.indid < 2 AND OBJECTPROPERTY(o.id, 'IsMSShipped') = 0)

TSQL Storage

SELECT 
t.NAME AS TableName,
s.Name AS SchemaName,
p.rows AS RowCounts,
SUM(a.total_pages) * 8 AS TotalSpaceKB, 
CAST(ROUND(((SUM(a.total_pages) * 8) / 1024.00), 2) AS NUMERIC(36, 2)) AS TotalSpaceMB,
SUM(a.used_pages) * 8 AS UsedSpaceKB, 
CAST(ROUND(((SUM(a.used_pages) * 8) / 1024.00), 2) AS NUMERIC(36, 2)) AS UsedSpaceMB, 
(SUM(a.total_pages) - SUM(a.used_pages)) * 8 AS UnusedSpaceKB,
CAST(ROUND(((SUM(a.total_pages) - SUM(a.used_pages)) * 8) / 1024.00, 2) AS NUMERIC(36, 2)) AS UnusedSpaceMB
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
