How to Round to Nearest Whole Number

Transact-SQL
#1

Hi experts,
I'm retrieving data file sizes:
with fs
as
(select database_id, type, (size * 8.0 / 1024) size
from sys.master_files
)
select
name,
(select sum(size) from fs where type = 0 and fs.database_id = db.database_id) DataFileSizeInMB,
(select sum(size) from fs where type = 1 and fs.database_id = db.database_id) LogFileSizeInMB
from sys.databases db
ORDER bY NAME

The resultset contains a number with 6 decimal places and I want to derive a whoile number:

DBName 5120.000000 1058.437500

I've tried a few things but I can't get the result to be 5120 1058
Can anyone provide any tips? Thanks

Please try

Cast ( column as int )
Or
Cast ( value as int )

Hope it helps

Or you could use

Thanks for your ideas, harishgg1. I guess I'm not sure how to plug in your suggestion to my TSQL code.
I tried this:

with fs
as
(select database_id, type, (size * 8.0 / 1024) size
from sys.master_files
)
select @@SERVERNAME,
name,
(select sum(size) from fs where type = 0 and fs.database_id = db.database_id) CAST (DataFileSizeInMB as int),

(select sum(size) from fs where type = 1 and fs.database_id = db.database_id) LogFileSizeInMB

from sys.databases db
It gives this error:
Incorrect syntax near 'DataFileSizeInMB'.

       a.database_id, 
       Cast(( a.size * 8.0 / 1024 ) AS INT) AS DataFileSizeinMB, 
       Cast(( b.size * 8.0 / 1024 ) AS INT) AS LogFileSizeinMB 
FROM   (SELECT * 
        FROM   sys.master_files 
        WHERE  type = 0) a 
       JOIN (SELECT * 
             FROM   sys.master_files 
             WHERE  type = 1) b 
         ON a.database_id = b.database_id 
       JOIN sys.databases db

Yes harishgg1. I used Cast ( value as int ) and it worked perfectly. Thank you
