Trying to move NDF file to the PRIMARY filegroup

Question

We have a DB with an MDF file and an NDF file on different filegroups: MDF is on PRIMARY and NDF is on XYZ filegroup.
Is there a way to move the NDF file from the XYZ filegroup to the PRIMARY filegroup (so they are both on the same filegroup)?

Hi Ben
As Olaf already told you can change filegroup for file once done. But before deleting you have to make sure you move all data.
I tried on my machine to check, please use refrence of below code as steps
/**************Create database with 2 file groupse*************/
CREATE DATABASE [Check_filegroup]
CONTAINMENT = NONE
ON PRIMARY
( NAME = N'Check_filegroup', FILENAME = N'G:\Saurabh\Check_filegroup.mdf' ),
FILEGROUP [secondry]
( NAME = N'Check_filegroup_data1', FILENAME = N'G:\Saurabh\Check_filegroup_data1.ndf' )
LOG ON
( NAME = N'Check_filegroup_log', FILENAME = N'G:\Saurabh\Check_filegroup_log.ldf' )
GO
/**************create table on secondry file group*************/
USE Check_filegroup
create table test (col1 int , col2 varchar (50)) on [secondry]
/**************insert data into table*************/
USE Check_filegroup
insert into test values (1,'saurabh')
insert into test values (1,'saurabh')
insert into test values (1,'saurabh')
insert into test values (1,'saurabh')
insert into test values (1,'saurabh')
/**************Transfer data into primary file group*************/
USE Check_filegroup
create table test1 (col1 int , col2 varchar (50)) on [Primary]
insert into test1
select * from test
Drop table Test
sp_rename test1, test
---> Do same for all tables and objects if created
/**************Clear Secondry group before delete*************/
USE Check_filegroup
GO
DBCC SHRINKFILE (N'Check_filegroup_data1' , EMPTYFILE)
GO
/************* Delete ndf file ***************/
USE [Check_filegroup]
GO
ALTER DATABASE [Check_filegroup] REMOVE FILE [Check_filegroup_data1]
GO
Please make sure you move all objects in file group and file , belofre deleting them.
