Hi,
I am trying to create a script that will loop through the tables and return space used info for each table. Some tables are not owned by dbo so I need to use the owner.table syntax. The problem is I can't use that syntax without quotes, but it won't translate the variable with them on. Thanks in advance for your time and assistance.

DECLARE @table varchar(64),
@sql varchar(150),
@owner varchar(20)
DECLARE curTable SCROLL CURSOR FOR SELECT name FROM sysobjects WHERE Type = 'U' And Name <> 'dtproperties' ORDER BY name
OPEN curTable
FETCH FIRST FROM curTable INTO @table
WHILE (@@FETCH_STATUS = 0)
BEGIN
select @owner=user_name(uid) from sysobjects where name = @table
exec sp_spaceused '@owner.@table'
FETCH NEXT FROM curTable INTO @table
END
CLOSE curTable
DEALLOCATE curTable

Declare a temp var and set it to owner.table name

DECLARE @table varchar(64),

@sql varchar(150),

@owner varchar(20),

@temp varchar(90)

DECLARE curTable SCROLL CURSOR FOR SELECT name FROM sysobjects WHERE Type = 'U' And Name <> 'dtproperties' ORDER BY name

OPEN curTable

FETCH FIRST FROM curTable INTO @table

WHILE (@@FETCH_STATUS = 0)

BEGIN

select @owner=user_name(uid) from sysobjects where name = @table

set @temp = @owner +'.'+@table

exec sp_spaceused @temp

FETCH NEXT FROM curTable INTO @table

END

CLOSE curTable

DEALLOCATE curTable

I rolled the following procedure a few years back for the same thing. I place it in the master database and use the sp_prefix so I can call it from any database context.

The procedure includes switches to update statistics so the results are accurate. The first time you run it, pass 1 for both parameters. Depending on the size of your database, updating those statistics may take some time. If you trust the statistics (sp_spaceused uses statistics, not actual table data), then you can pass 0 for both parameters and it will run quickly.

USE MASTER
GO

SET QUOTED_IDENTIFIER, ANSI_NULLS ON 
GO

IF EXISTS (SELECT * FROM dbo.sysobjects WHERE id = object_id(N'[dbo].[sp_spaceused_Report]') 
              AND OBJECTPROPERTY(id, N'IsProcedure') = 1)
  DROP PROC dbo.sp_spaceused_Report 
GO

CREATE PROC dbo.sp_spaceused_Report(
@UpdateUsageFirst smallint = 0,
@CountRowsFirst   smallint = 0
)
