The space used by tables

Does this procedure accurately show the space used in db? I doubt the results.

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 order BY tablename

--Final cleanup!
DROP TABLE #TempTable

Sorry for creating this post. StackO sure buggies - no formatting toolbar today.

Your code displays a tabular representation of the space used. You can also simply run sp_spaceusedwithout parameters to get a general overview of the size of the entire database. What makes you doubt the results?

You might want to use one of the system dynamic views / functions

, , sys.dm_db_index_physical_stats, , :

select * from sys.dm_db_index_physical_stats ( 
    DEFAULT 
  , DEFAULT 
  , DEFAULT 
  , DEFAULT 
  , 'DETAILED'
)
