I Am writing here two ways to find the database table size
Method One 1:
---------------------------------------------------
SELECT CASE WHEN (GROUPING(sob.name)=1) THEN 'All_Tables'
ELSE ISNULL(sob.name, 'unknown') END AS Table_name,
SUM(sys.length) AS Byte_LengthFROM sysobjects sob, syscolumns sysWHERE sob.xtype='u' AND sys.id=sob.idGROUP BY sob.nameWITH CUBE
Method One 2:
---------------------------------------------------
Ever wonder how big a table really is in your database? You know
there are a million rows in the table, but how much space is that really
taking?
SQL Server provides a built-in stored procedure that you can run to
easily show the size of a table, including the size of the indexes…
which might surprise you.
Syntax: sp_spaceused ‘Tablename’
Method One 3:
---------------------------------------------------
Actually SQL Server gives you everything you need with its Stored Procedure
sp_spaceused.
Unfortunately this SP does not support iterating over all tables in a
database, so we needed to leverage another (undocumented) Stored
Procedure
sp_msForEachTable.
SET NOCOUNT ON
DBCC UPDATEUSAGE(0)
-- DB size.
EXEC sp_spaceused
-- Table row counts and sizes.
CREATE TABLE #t
(
[name] NVARCHAR(128),
[rows] CHAR(11),
reserved VARCHAR(18),
data VARCHAR(18),
index_size VARCHAR(18),
unused VARCHAR(18)
)
INSERT #t EXEC sp_msForEachTable 'EXEC sp_spaceused ''?'''
SELECT *
FROM #t
-- # of rows.
SELECT SUM(CAST([rows] AS int)) AS [rows]
FROM #t
DROP TABLE #t
Method One 4:
---------------------------------------------------
CREATE PROCEDURE GetAllTableSizes
AS
/*
Obtains spaced used data for ALL user tables in the database
*/
DECLARE @TableName VARCHAR(100) --For storing values in the cursor
--Cursor to get the name of all user tables from the sysobjects listing
DECLARE tableCursor CURSOR
FOR
select [name]
from dbo.sysobjects
where OBJECTPROPERTY(id, N'IsUserTable') = 1
FOR READ ONLY
--A procedure level temp table to store the results
CREATE TABLE #TempTable
(
tableName varchar(100),
numberofRows varchar(100),
reservedSize varchar(50),
dataSize varchar(50),
indexSize varchar(50),
unusedSize varchar(50)
)
--Open the cursor
OPEN tableCursor
--Get the first table name from the cursor
FETCH NEXT FROM tableCursor INTO @TableName
--Loop until the cursor was not able to fetch
WHILE (@@Fetch_Status >= 0)
BEGIN
--Dump the results of the sp_spaceused query to the temp table
INSERT #TempTable
EXEC sp_spaceused @TableName
--Get the next table name
FETCH NEXT FROM tableCursor INTO @TableName
END
--Get rid of the cursor
CLOSE tableCursor
DEALLOCATE tableCursor
--Select all records so we can use the reults
SELECT *
FROM #TempTable
--Final cleanup!
DROP TABLE #TempTable
GO
Exec GetAllTableSizes
