expected query as:

SELECT `employee`.*
FROM `employee`
WHERE `employee`.`Employee_Code` like '%s%'
  AND `employee`.`Employee_Name` like '%s%'
  AND `employee`.`Employee_Age` like '%s%'
  AND `employee`.`Employee_Contact_No` like '%s%'
  AND `employee`.`Department` like '%s%'
  AND `employee`.`Salary_Grade` like '%s%'
  AND `employee`.`Employee_Email` like '%s%' DESC
LIMIT 10
