How do I see the size of all the tables - sql-server

Question

I've created a table in my database by mistake which has zero rows, and I want to know a systemic way to find out that table. I know we can use sp_spaceused to get the number of rows but how can I do it for all the tables.

Answer 1

Paste the output of the below query in a new SQL Editor and do a visual scan of the output
SELECT *
FROM (
SELECT 1000 * ROW_NUMBER () OVER (ORDER BY name) rk,
' sp_spaceused ' + name spused
FROM sys.Tables
UNION ALL
SELECT 1 + 1000 * ROW_NUMBER () OVER (ORDER BY name), ' go'
FROM sys.Tables
) a
ORDER BY a.rk

Below you can find the query with additional details
SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED
SELECT
CASE WHEN FG.Name IS NULL THEN DS.Name ELSE FG.Name END AS 'FileGroupName'
,DB_NAME() AS 'DatabaseName'
,OBJECT_SCHEMA_NAME(P.OBJECT_ID) AS 'Schema'
,OBJECT_NAME(P.OBJECT_ID) AS 'TableName'
,CASE WHEN P.index_id = 0 THEN 'HEAP' ELSE I.name END AS 'IndexName'
,CASE WHEN P.index_id IN (0,1) THEN 'data' ELSE 'index' END AS 'Type'
,P.partition_number AS 'PartitionNumber'
,CAST(P.reserved_page_count * 0.008 AS NUMERIC(18,2)) AS 'ReservedSize_MB'
,CAST(P.used_page_count * 0.008 AS NUMERIC(18,2)) AS 'UsedSize_MB'
,P.row_count AS 'RowCount'
FROM
sys.dm_db_partition_stats P
INNER JOIN sys.indexes I ON I.OBJECT_ID = P.OBJECT_ID AND I.index_id = P.index_id
INNER JOIN sys.data_spaces DS ON DS.data_space_id = I.data_space_id
LEFT OUTER JOIN sys.filegroups FG ON FG.data_space_id = DS.data_space_id
WHERE
OBJECTPROPERTY(p.OBJECT_ID, 'ISMSSHipped') = 0
ORDER BY ReservedSize_MB DESC
Below you can find the query for details of partitioned tables
