Question

In my application i have one value which is stored as boolean.
How can i change that Boolean value to text when displaying in grid view.

I have this sql

SELECT     Driver.FirstName + Driver.LastName AS DriverName, Driver.PhoneNumber, 
           Booking.BookingId, Booking.DriverRating, Driver.CarId AS CarUsed 
FROM       Booking 
INNER JOIN Driver ON Booking.DriverId = Driver.DriverId 
WHERE      Booking.DriverRating = 0

I am retrieving all the all the driver rating which is false(0). Now when i display it to grid view i want to change boolean value false to unsatisfactory.

How can i do it within sql query?

Answer 1

How bout retrieving it from the server as a string to begin with?

For example

SELECT Driver.FirstName + Driver.LastName AS DriverName, Driver.PhoneNumber, Booking.BookingId,
 Case Booking.DriverRating When 0 then 'Unsatisfactory' else 'Satisfactory' end as DriverRating,   
Driver.CarId AS CarUsed 
FROM Booking 
INNER JOIN Driver ON Booking.DriverId = Driver.DriverId 
WHERE (Booking.DriverRating = 0)

Or in your case since you are already using a where clause:

SELECT Driver.FirstName + Driver.LastName AS DriverName, Driver.PhoneNumber, Booking.BookingId, 
    'Unsatisfactory' as DriverRating,
    Driver.CarId AS CarUsed 
FROM Booking INNER JOIN Driver ON Booking.DriverId = Driver.DriverId 
WHERE (Booking.DriverRating = 0)
