The Original SQL Statement is:
SELECT SA.[RequestStartDate] as \'Service Start Date\',
SA.[RequestEndDate] as \'Service End Date\',
FROM
(......)SA
WHER
Changed to:
SELECT FORMAT(SA.[RequestStartDate],'dd/MM/yyyy') as 'Service Start Date', SA.[RequestEndDate] as 'Service End Date', FROM (......)SA WHERE......
Have no idea which SQL engine you are using, for other SQL engine, CONVERT can be used in SELECT statement to change the format in the form you needed.
