How to combine 2 SQL queries?

Question

I have this my first query:

SELECT (Temperature) + 273.15  FROM tbl_Temperature;

( Temperature is the column name and tbl_Temperature is the table name.)

Data in database dbTemp :

25,3
26,7
28,4

(This are Temperature in Celsius)

output
272,45
273,85
275,55

(this are temperature in Kelvin)

This is my second query:

SELECT MAX (Temperature) FROM tbl_Temperature;

Data in database dbTemp :

25,3
26,7
28,4

Output

28,4

(This are Temperature in Celsius)

I want to combine these queries.

Data in database dbTemp :

25,3
26,7
28,4

(This are Temperature in Celsius)

Desired output

272,45
273,85
275,55

max: 275,55

(This are temperature in Kelvin)

So what I want is that it shows the data in Kelvin and the maximum in Kelvin .

Answer 1

You simply need to do:

SELECT Temperature + 273.15  FROM tbl_Temperature;
UNION ALL
SELECT  'max: ' + cast(MAX (Temperature)+ 273.15 as nvarchar)  FROM tbl_Temperature;
