LKBEN11462: Find the actual size of tempDB on MS SQL-Server.
Symptom
You need to find out how much space is needed by TempDB on your SQL Server.
Cause
TempDB can become big and knowing the current size is important.
Solution
You can use the GUI, right click on your TempDB and find the size. This is the initial size or startup size of TempDB. When TempDB grows, this will not match the actual current size.
To get the actual current size you can use the following command:
sp_helpdb 'TempDB'
Another possibility is to use:
select Name,size*8 as KB from Tempdb.sys.database_files
This will show a different view of TempDB and you will have to count the sizes together.
Full details can be seen with:
select * from Tempdb.sys.database_files
Please note that the size column is in KB.
