This is typically a task that is performed in the presentation-layer and not in the database.

If you must do it in SQL then you can use:

SELECT *
FROM   shift_t
PIVOT (
  MAX(shift)
  FOR shift_date IN (
    DATE '2022-07-01' AS "07/01/2022",
    DATE '2022-07-02' AS "07/02/2022",
    DATE '2022-07-03' AS "07/03/2022",
    DATE '2022-07-04' AS "07/04/2022",
    DATE '2022-07-05' AS "07/05/2022",
    DATE '2022-07-06' AS "07/06/2022",
    DATE '2022-07-07' AS "07/07/2022",
    DATE '2022-07-08' AS "07/08/2022",
    DATE '2022-07-09' AS "07/09/2022"
  )
)

Which, for the sample data, outputs:

LOCATION	NAME	07/01/2022	07/02/2022	07/03/2022	07/04/2022	07/05/2022	07/06/2022	07/07/2022	07/08/2022	07/09/2022
HYD	Rose	C	W	W	C	C	C	C	C	W

Note: You must hard-code the date values. They cannot be provided dynamically using a PIVOT statement. If you want a dynamic pivot then look at this question (and then ignore it and perform the task in the presentation-layer and not in SQL).
