Answer 1

Try something like this:

select (cast(day as varchar(2)) + '/' 
    + cast(month as varchar(2)) + '/' 
    + cast(year as varchar(4))) as xdate 
from table1

Answer 2

If TSQL / SQL-SERVER, then + only works to concatenate strings... So do some conversions on your numbers in that case:

select
   CONVERT(VARCHAR, day) + '\' + CONVERT(VARCHAR, month) + '\' ... etc.

Answer 3

Since you are Casting int to Varchar, so you need to use CAST or CONVERT function

CAST and CONVERT

Try like this

select (Cast(day AS Varchar(10)) + '\' + Cast(month AS Varchar(10)) + '\' + Cast(year AS Varchar(10))) as xdate from table1

(Or)

select (Cast(day AS Varchar(10)) + '-' + Cast(month AS Varchar(10)) + '-' + Cast(year AS Varchar(10))) as xdate from table1

Answer 4

CONVERT(date, , 103) converts a date to a string representation in dd/mm/yyyy form

SELECT CONVERT(date,DATEFROMPARTS([year],[month],[day]),103)
