While executing the below query to find the results getting the below error:

Do I need to use cast/convert statement?

Msg 8117, Level 16, State 1, Line 1
Operand data type nvarchar is invalid for sum operator.

select sum(database_name), backup_size/(1024*1024),
backup_finish_date,type from backupset where type ='D'
--order by backup_finish_date asc
group by database_name

Thanks.

No. Cast/convert will not help here. You need to remove SUM() around database_name.

Evenafter that the query fails.

What are you trying to achieve? Other may help you to rewrite the query.

Hello,

alter the query.
