Moving SQL tempdb to another drive

Today I urgently needed to move tempdb from one drive to another to free up space. So I googled to find a script and found this one by Brent Ozar. It has been added to StackExchange and refined a bit.

DECLARE @newDriveAndFolder VARCHAR(8000);
SET @newDriveAndFolder = ‘Z:\YourTempDBfolder’;
SELECT [name] AS [Logical Name]
,physical_name AS [Current Location]
,state_desc AS [Status]
,size/1024 AS [Size(MB)]
,’ALTER DATABASE tempdb MODIFY FILE (NAME = ’ + QUOTENAME(f.[name])
+ CHAR(9) /* Tab /
+ ’,FILENAME = ‘’’ + @newDriveAndFolder + CHAR(92) / Backslash / + f.[name]
+ CASE WHEN f.[type] = 1 / Log */ THEN ‘.ldf’ ELSE ‘.mdf’ END  + ‘’‘’
+ ‘);’
AS [Create new TempDB files]
FROM sys.master_files f
WHERE f.database_id = DB_ID(N’tempdb’)
ORDER BY f.[type];

Change the newDriveAndFolder variable and run the script and it will generate the T-SQL statements you need to move them.

ALTER DATABASE tempdb MODIFY FILE (NAME = [temp2] ,FILENAME = ‘F:\MSSQLDATA\temp2.mdf’);
ALTER DATABASE tempdb MODIFY FILE (NAME = [temp3] ,FILENAME = ‘F:\MSSQLDATA\temp3.mdf’);
ALTER DATABASE tempdb MODIFY FILE (NAME = [temp4] ,FILENAME = ‘F:\MSSQLDATA\temp4.mdf’);
ALTER DATABASE tempdb MODIFY FILE (NAME = [temp5] ,FILENAME = ‘F:\MSSQLDATA\temp5.mdf’);

Worked like a charm
