Get the TimeValue From SQL Server DMZMGMT SQL server database in Unix and then send an email to users about elapsed time

I have this query in SQL server , It yields time difference value between two steps. I need to send an email via UNIX with the time difference value .

So I need to do the following steps which i am not aware of: 1. Connect Unix to SQL server to yield time difference value. 2. Send an email with time difference value.

Query:

select  Audit1.Time_  Time_Full_Calc , Audit2.Time_  Time_Step2_Calc  ,Cast(Audit2.Time  -  Audit1.Time  As Time ) As TimeDifferencefrom Schema.dbo.Table Audit1 inner join Schema.dbo.Table Audit2on CAST(Audit1.Time AS date) = CAST(Audit2.Time AS date)where CAST(getdate() AS date) = CAST(Audit2.Time AS date)and  CAST(getdate() AS date) = CAST(Audit1.Time AS date)

Thanks In Advance.
