It thinks ResevedSpace is a get a handle on how your database and tables are changing. I made a minor mod below which simply rips out the ' KB' and casts the data as INT. updated with the following approach. I have previously written about that subject on the following blogs. In this tip we look at some queries that can be used to do this. Oracle Database provides data dictionary views and PL/SQL packages that allow you to display information about the space usage of schema objects. In the Object Explorer in SQL Server Management Studio, go to the database and expand it. It’s very useful before deletion. [' + o.name + ']' > @objname order by 1, update @spaceusedset  reserved = REPLACE(reserved, ' KB', '')  ,data  = REPLACE(data, ' KB', '')  ,index_size = REPLACE(index_size, ' KB', '')  ,unused  = REPLACE(unused, ' KB', ''), http://nazermohamed.blogspot.co.uk/2012/03/quick-dump-of-all-table-sizes-of.html. Cannot insert duplicate key. If there is enough space available on the page it will be used and allocated by the newly inserted record. If you find out more details about space used by a table like size of minimum and maximum record and numbers of page record then you can use below query. schema1.table, schema2.table would result in more than 2 rows of output). Highlight the database of interest. It helped a lot. Using the information_schema.tables table, Using the sys.tables table joined to indexes and partitions, this query allows you to know the last time a table was accessed or update, SQL Server error conversion from XML to NVARCHAR, Violation of UNIQUE KEY constraint. It can basically be any character …, How to convert XML into NVARCHAR with SQL Server? There are several ways that you can get this + t1.name      FROM sys.tables t1     INNER JOIN sys.schemas t2 ON ( t1.schema_id = t2.schema_id ); OPEN c1;    FETCH NEXT FROM c1 INTO @table_name;   WHILE @@FETCH_STATUS = 0    BEGIN      SET @table_name = REPLACE(@table_name, '[','');     SET @table_name = REPLACE(@table_name, ']',''); -- make sure the object exists before calling sp_spacedused    IF EXISTS(SELECT OBJECT_ID FROM sys.objects WHERE OBJECT_ID = OBJECT_ID(@table_name))    BEGIN     INSERT INTO @temp_table EXEC sp_spaceused @table_name, false ;    END        FETCH NEXT FROM c1 INTO @table_name;    END;    CLOSE c1;    DEALLOCATE c1; SELECT   t1.tablename AS TableName   , t1.row_count AS TableRows   , CAST(REPLACE(t1.reserved, ' KB', '') AS INT) AS ReservedSpace   , CAST(REPLACE(t1.data, ' KB', '') AS INT) AS DataSize   , CAST(REPLACE(t1.index_size, ' KB', '') AS INT) AS IndexSize   , CAST(REPLACE(t1.unused, ' KB', '') AS INT) AS UnusedSpace   , t2.schemaname AS SchemaName  FROM @temp_table t1    INNER JOIN @tab1 t2 ON (t1.tablename = t2.tablename )   ORDER BY CAST(REPLACE(t1.reserved, ' KB', '') AS INT) desc; END try   BEGIN catch    SELECT -100 AS l1   , ERROR_NUMBER() AS tablename   , ERROR_SEVERITY() AS row_count   , ERROR_STATE() AS reserved   , ERROR_MESSAGE() AS data   , 1 AS index_size, 1 AS unused, 1 AS schemaname   END catchENDGO. Three different ways, but similar are presented here to display SQL Server tables and disk space used by each table.

For compliance legal reasons, depending on the business area, the data might need to be kept and backed-up more years. + t1.name  FROM sys.tables t1INNER JOIN sys.schemas t2 ON ( t1.schema_id = t2.schema_id );   OPEN c1;FETCH NEXT FROM c1 INTO @table_name;WHILE @@FETCH_STATUS = 0BEGIN          SET @table_name = REPLACE(@table_name, '[','');        SET @table_name = REPLACE(@table_name, ']','');        -- make sure the object exists before calling sp_spacedused        IF EXISTS(SELECT OBJECT_ID FROM sys.objects WHERE OBJECT_ID = OBJECT_ID(@table_name))        BEGIN                                INSERT INTO @temp_table EXEC sp_spaceused @table_name, false ;                UPDATE @temp_table SET tablename = @table_name WHERE row_id =                    (SELECT MAX(row_id) FROM @temp_table)        END                FETCH NEXT FROM c1 INTO @table_name;END;CLOSE c1;DEALLOCATE c1;INSERT INTO [DbStatistics] ( DateReporting, TableName, [RowCount], Reserved, Data, IndexSize, Unused )SELECT GETDATE() as DateReporting, tablename as TableName, row_count as [RowCount], CONVERT(INT,REPLACE(reserved,'KB','')) as Reserved, CONVERT(INT,REPLACE(data,'KB','')) as Data, CONVERT(INT,REPLACE(index_size,'KB','')) as IndexSize, CONVERT(INT,REPLACE(unused,'KB','')) as UnusedFROM @temp_table;SELECT 1  END tryBEGIN catchSELECT -100 AS l1,       ERROR_NUMBER() AS tablename,       ERROR_SEVERITY() AS row_count,       ERROR_STATE() AS reserved,       ERROR_MESSAGE() AS data,       1 AS index_size, 1 AS unused, 1 AS schemanameEND catchUSE SECREADER BEGIN tryDECLARE @table_name VARCHAR(500) ;DECLARE @schema_name VARCHAR(500) ;DECLARE  @temp_table TABLE (            tablename sysname,       row_count INT,       reserved VARCHAR(50) collate database_default,       data VARCHAR(50) collate database_default,       index_size VARCHAR(50) collate database_default,       unused VARCHAR(50) collate database_default,        row_id INT IDENTITY(1,1));DECLARE c1 CURSOR FORSELECT t2.name + '.'
