Regarding Filegroup( table prtition) in ms sql server

Hi,

I want to create t-sql job for automatic creating of new ndf file and automatic dropping/removing same ndf file  based on input parameter (ID and number of rows).  Is it possible in sql server?

I want to add below scripts and conditions in t-sql job:
/*Craete New File Group*/
ALTER DATABASE USERDB Add FileGroup FG_ID
GO

/*Step 2: Add Files to New File Group*/
ALTER DATABASE USERDB
ADD FILE
(
    NAME = [FILE_ID],
    FILENAME = 'C:\SecFiles\ID.ndf',
    SIZE = 5MB    
)
TO FILEGROUP FG_ID;
GO

/*Step 3: Creating a Partition Range Function*/
CREATE PARTITION FUNCTION IDRangePFN (int)
AS RANGE LEFT FOR VALUES
(10,20,30,40,50,60,70)
GO

/*Step 4: Creating a Partition Scheme*/
CREATE PARTITION SCHEME IDRangePS
AS PARTITION IDRangePFN
TO (FG_ID,[PRIMARY])
GO

Condition:
If  id=21 and number of rows (if rowcount=0)---drop ndf file
If  id=21 and number of rows (if rowcount<>0)---no drop ndf file.

after above condition

again creating new table partition function,.schema, range.....

If  id=43 and number of rows (if rowcount=0)---drop ndf file
If   id=43 and number of rows (if rowcount<>0)---no drop ndf file.

Is it possible using t-sql proc?

regards,

Yes.  Yo will need to use dynamic SQL.  Keep in mind the following issue: if aligning the physical storage pruning with logical partition pruning, I would avoid thinking in terms of number of rows but rather think in terms of OS IO ressources. Having a new files created in function of partition ca be quite cumbersome to manage.

Hope this helps...
