Removing Filegroup

Mar 8, 2001

Hi all,

I am trying to remove one of the filegroups in the development database to shrink its size down. I started with emptying and removing its files and ran:
dbcc shrinkfile
(pubs_data_1,emptyfile)
go

and it ran fine, with 'DBCC execution completed' message

but when I tried :

alter database pubs
remove file pubs_data_1
go

I got 'pubs_data_1 cannot be removed because it is not empty'.
I even tried to go to each of the tables and delete from them first which didn't work, then drop all tables in that filegroup (I knew which tables are located on that filegroup), that didn't work either.

Any ideas? Is there a way to check what else sits on that filegroup?

Thanks

Removing A Filegroup

Apr 25, 2000

Hello,

A few days ago one our database's default filegroup filled up. To solve the problem one of my colleagues created a new filegroup. This didn't solve the problem as no objects were placed on this filegroup and the initial one is still full. The idea was to expand the original filegroup over a new physical disk, not to create a new filegroup on that disk. Unfortunately, this is what happened.
To solve this I want to delete the new filegroup, but when I issue the command 'alter database PvgOmcsOds remove filegroup ternary' I get the message 'Server: Msg 5042, Level 16, State 7, Line 1 The filegroup 'ternary' cannot be removed because it is not empty.' Yet there're no objects placed on this filegroup.
How can I get rid of this filegroup?

i understand that the filegroup for a table can be specified in the CREATE Table statement. just out of curiosity, is there any way to move a table to a different filegroup, that too, if the table contains data.

Hi,
There is a table which is about 50GB is size.
I am thinking of placing the database of this table into a separate .ndf on a separate drive on the server.
Is it possible to place this particular table into a searate drive to increase the performance even more?
Basically my question is: is it possible to place tables into separate .ndf files?
Thanks

Filegroup

Hi,
I have created a database with two filegroups called FG_GroupData, FG_GroupHistory.
FG_GroupData is set as default.
FG_GroupData contains two secondary data files i.e. GroupData1.ndf and GroupData2.ndf
I can create a table so that it is stored in FG_GroupHistory. i.e.
CREATE TABLE dbo.OrdersHistory
(
OrderID int NOT NULL,
ProductID int NOT NULL,
CustomerID int NOT NULL,
UnitPrice money NOT NULL,
OrderQty smallint NOT NULL
)
ON FG_GroupHistory
Questions:
1)
How do I add tables to each .ndf file inside a group i.e. FG_GroupData
For example, how do I add a table to GroupData1.ndf and one to GroupData2.ndf ?
2)
I guess there is no need to place the file name i.e. .ndf inside the select query
Thanks

What is the advantage of having two secondary files inside a filegroup.
For example, I can create a table and place it inside a filegroup which obviously will use the secondary files.
Not sure why some DBAs create just one but otherscreate more than one secondar files in a filegroup.
I have read the booksonline but can not figure out the advantages.
Thanks
