DBCC Results into a Table Brings Errors!

If you run the script below, it will cause an error. However, if you
run the select portion after the error, it will have accomplished the
desired result. Unfortunately, the table has to be manually dropped
after the proc is run. Any ideas why'? USing the GO keyword is not
an option as it will blow the rest of the script.
CREATE TABLE #db_file_information(
fileid integer,
theFileGroup integer,
Total_Extents integer,
Used_Extents integer,
db varchar(30),
file_Path_name varchar(300)--,
-- File_Free_space decimal(15,2),
-- Percent_Free decimal(15,2)
)
-- Get the size of the datafiles
insert into #db_file_information exec('DBCC showfilestats')
-- add two columns to the temp table
alter table #db_file_information add dude as
((Total_Extents-Used_Extents)/(Total_extents*1.0))
select * from #db_file_information
drop table #db_file_informationTry,
use northwind
go
CREATE TABLE #db_file_information(
Fileid bigint,
[FileGroup] bigint,
TotalExtents bigint,

go

exec('DBCC showfilestats with NO_INFOMSGS')
-- add two columns to the temp table
alter table #db_file_information

DBCC InputBuffer statement to be part of a select statement

I want to use DBCC inputbuffer function for all the spids in sysprocesses table without using a cursor or loop. In other words, I want to have the value of dbcc inputbuffer part of the select statement directly or indirectly. Is there a way??SQLDBAxxx,
Try running the following:

----------
set nocount on
select 'exec DBCC INPUTBUFFER('+convert(varchar,spid)+')'
from sysprocesses
go
----------

This will generate the DBCC code you need to run; it won't run
DBCC in the TSQL mode that you need. You can save the result set
and reload it to run it. Simple, but works...

I've never been able to execute a DBCC statement using ANSI-SQL syntax( select,update, insert ).|||SQLDBAxxx,

I want to capture the input buffer for a given spid. I can do it thro a cursor or loop but if my recordset is big then by the time it comes to execute the dbcc inputbuffer for the last spid the inputbuffer may have changed. That is the reason I wanted to try by some other way to narrow down the time difference.

dbcc dbreindex on all tables/indexes and slow

This is what i ran and it was slow
declare reindex_cursor insensitive cursor for
select TABLE_NAME
from INFORMATION_SCHEMA.TABLES
where objectproperty(object_id(TABLE_NAME), 'IsMSShipped') = 0
and table_type = 'Base table'
declare @.table_name sysname
open reindex_cursor
fetch next from reindex_cursor into @.table_name
while (@.@.fetch_status = 0)
begin
print ('dbcc dbreindex(' + @.table_name + ')' )
exec ('dbcc dbreindex(' + @.table_name + ')' )
fetch next from reindex_cursor into @.table_name
end
close reindex_cursor
deallocate reindex_cursor
Could the problem be because of the insensitive that i mentioned in the
cursor declaration ? I can see that the DBCC is still running and not being
blocked but its way too slow. If I do cancel in between, will it rollback
everything ?For something like that I always use a STATIC cursor. You also don't need
to use dynamic sql as DBCC DBREINDEX will take a variable for the table
name. My guess why the operation is so slow is that your log and db files
probably don't have enough room in them for this and are constantly growing.
If your in full recovery mode you might want to backup your logs in between
so try something like this:
SET NOCOUNT ON
DECLARE @.TableName VARCHAR(100), @.Counter INT
SET @.Counter = 1
DECLARE curTables CURSOR STATIC LOCAL
FOR
SELECT Table_Name
FROM Information_Schema.Tables
WHERE Table_Type = 'BASE TABLE'
OPEN curTables
FETCH NEXT FROM curTables INTO @.TableName
SET @.TableName = RTRIM(@.TableName)
WHILE @.@.FETCH_STATUS = 0
BEGIN
SELECT 'Reindexing ' + @.TableName
DBCC DBREINDEX (@.TableName)
SET @.Counter = @.Counter + 1
-- Backup the Log every so often so as not to fill the log
IF @.Counter % 10 = 0
BEGIN
BACKUP LOG [Presents] TO [DD_Presents_Log] WITH NOINIT , NOUNLOAD
,
NAME = N'Presents Log Backup', NOSKIP , STATS = 10,
NOFORMAT
END
FETCH NEXT FROM curTables INTO @.TableName
END
CLOSE curTables
DEALLOCATE curTables

dynamic sql and what can accept variables. Can you provide some examples and
how can i figure it out ? Also the definition of insensitive and static
seemed to be the same from BOL. Btw, i got the initial script from google
too.

it isn't always spelled out but if you look at the entry in BOL it usually
gives a hint. If there are quotes around the option you can usually use a
variable.
DBCC DBREINDEX
( [ 'database.owner.table_name'
[ , index_name
[ , fillfactor ]
]
]

It will help you determine the best way to deal with fragmentation and
