I need to concat these columns as address

Answer 1

Try This select concat (EMP_HOUSE_NO,' ',EMP_STREET_NAME,' ',EMP_AREA,' ',EMP_PIN_CODE) as address from EMPLOYEE_DETAILS WHERE EMP_ID=1;

Answer 2

If you want spaces between the components, I would suggest concat_ws():

SELECT CONCAT_WS(' ', EMP_HOUSE_NO, EMP_STREET_NAME, EMP_AREA, EMP_PIN_CODE)
FROM EMPLOYEE_DETAILS
WHERE EMP_ID = 1;

Answer 3

SELECT CONCAT(EMP_HOUSE_NO,' ', EMP_STREET_NAME,' ', EMP_AREA) AS address

from EMPLOYEE_DETAILS

WHERE EMP_ID=1;
