I'm new to SQL 2005, but have been working with SQL 2000 for quite some time.
In studying for the SQL 2005 test 70-431, I'm working in Chapter 12 of the
Self Study guide, working on managing index fragmentation.
What I am trying to do is collect data from sys.dt_db_index_physical_stats
DMF. I'm creating a temporary table that houses the table name in the format
"schema.table". Then I am attempting to put some of that information into a
cursor, and run an ALTER INDEX on all tables that match the criteria I need.
Following is the script I've come up with:
set ansi_nulls on
set quoted_identifier on
if exists (select * from sys.objects where name='tmp_TableIndex')
begin
drop table tmp_TableIndex
end
create table tmp_TableIndex
(
TableName varchar(50),
AvgFragInPercent int,
AvgPageSpaceUsedInPercent int
)
insert tmp_TableIndex(TableName, AvgFragInPercent, AvgPageSpaceUsedInPercent)
select schema_name(sc.schema_id) + '.' + object_name(dt.object_id) as
'TableName',
dt.avg_fragmentation_in_percent,
dt.avg_page_space_used_in_percent
from sys.dm_db_index_physical_stats
(
db_id(db_name()), null, null, null, 'detailed'
)
dt
join sys.objects sc
on sc.object_id=dt.object_id
join sys.indexes si
on si.object_id=dt.object_id
and si.index_id=dt.index_id
where dt.index_ID<>0
and dt.avg_fragmentation_in_percent between 10 and 15
or dt.avg_page_space_used_in_percent between 60 and 75
declare c_Indexreorg cursor
for
select distinct TableName from tmp_TableIndex
open c_Indexreorg
fetch next from c_Indexreorg
while (@.@.FETCH_STATUS=0)
begin
ALTER index ALL on [TableName]
REORGANIZE
fetch next from c_Indexreorg
end
close c_Indexreorg
deallocate c_Indexreorg
The table is created, but I get the following error:
Msg 1088, Level 16, State 9, Line 46
Cannot find the object "TableName" because it does not exist or you do not
have permissions.
I made sure the tablename in the temp table was in schema.tablename format,
but that still didn't help.
What am I doing wrong? Is ALTER INDEX not allowed in a cursor?

Do you run this script under what account?

ms-help://MS.SQLCC.v9/MS.SQLSVR.v9.en/tsqlref9/html/d294dd8e-82d5-4628-aa2d-e57702230613.htm
If you scroll down towards the end, you will find a script that does exactly what you want to do. In
addition, the script will only reoorganize the index if it is fragmented in the first place.
To answer why your script doesn't work:
> fetch next from c_Indexreorg
You don't fetch the column from the cursor into any variables. You should have something like:
> fetch next from c_Indexreorg INTO @.v1, @.v1, ...
> ALTER index ALL on [TableName]
Here you have hardcoded the table name to "TableName", and you probably don't have a table with that
name in the database.

REORGANIZE'
exec (@.command)
fetch next from c_Indexreorg
end
close c_Indexreorg
deallocate c_Indexreorg
Once I created a couple more variables (I had the @.table_name variable on a
previous iteration of the script but took it out, thinking it was making it
to complex), and not slamming the schema name and table name together in my
temporary table, it seemed to work better.
THanks for all that responded.

Why wouldn't you want to reorg if the fragmentation level is high?
